Depends on the courses you're tracking on but you can usually cut your lap times by more seconds per dollar doing basically anything other than adding boost. Improving braking, suspension, grip, and aero will cost you about as much as adding boost alone and will get you better lap times on most courses.
The boost curve from a centrifugal supercharger makes you use more throttle at the bottom of a pull, but as the rpms climb the boost also climbs (exponentially) and “blows the tires off” the car. It is especially pronounced on FWD with street tires.

Good morning SA! It seems more enjoyable without the S/C. You can rip thru gears and play with the throttle a lot more without the constant burning of rubber. I believe you guys made the right choice!
Lower power isn't bad. Miata is a ton of fun, FRS/BRZ/GR86 is fun. They don't have high power but still great. FWD has special challenges in grip due to weight transfer to back tires... I have a fast car I can't really use anywhere. It sits in the garage and comes out a few times during the summer. So, cutting back the power to have something fun to get around in without going to jail is good.
I have a kraftwerks civic I’ve put thousands of miles on it and my wife drives it too it’s incredible. If you don’t wanna rip the tires off you pedal it or shift up the power is always there if/when you want it and if you don’t want it you can drive out of boost easy. I added a rfl blow off valve so every gear change is fun and sounds cool. To each his own!
I’m of the mindset that i should have gotten better with a crv all wheel drive setup with the supercharger,maybe that should be another video suggestion
Way too complex, expensive and heavy. All they needed was a 255 square setup on some nice 300 tread wear tires and maybe lowering the boost a bit if required.
@@CrossWindsPat 255/35R18 200TW tires + add an external wastegate on the charge pipe plugged into a 4-port solenoid (boost by gear setup) Problem solved ✅
I had a 5th gen Camaro, did normal bolt on and really enjoyed the car, put a supercharger on and never really enjoyed it after. It was a blast in a straight line but it took the sportiness away. I drove it to the dealer with the mods all removed to trade it and actually missed how the car was in stock form.
More Power = More Problems. Just a fact. The more strain you put on parts to sustain that power, the lower the lifetime expectancy. And the other train of thought... Driving Overpowered cars = Chore .... Driving Underpowered cars = space to have fun.... not running out of road or fighting for traction.
Wisest decision ever. I build my K20 without the k24. Got the Brian crowder light weight striker, 87mm pistons, BC stage 3 cams. Running 2.2L. Having the extra power and torque balancing with the cars setup it’s super fun to drive. I’d post pics but don’t think I can on here.
Glad to see you guys thriving up North. Congrats on nearly 650k subscribers. I always say add power until you reach the limits of the chassis/tire. With light FWD cars on street tires, that's a pretty low limit. 250-300 whp is probably that limit for most people. Even the newer CTRs with much better suspension design start to become a handful on street tires above 350-400 whp.
Not surprised at all; I had a crx back in the day that made 300whp and in a street race would get beat by anything from a dig. Highway and the track with r compounds was different but 245whp on that chassis sounds perfect. 👍
Honestly I love the 8th gen civic si and seeing you build the supercharger set up was awesome and I’m glad I’m now seeing an all motor set up really love seeing this car on camera
You guys should install an ecu controlled wastegate on the charge pipe. So your tuner can limit you boost by whatever values he wants. Like limit it per gear, limit in per mode setting, etc. Seen a couple guys doing this lately and it's really neat
Definately true, If you are drag racing you need the power. For daily driving I've been at ~240hp 197 ft/lbs Crank in my CL9 for 8 years now, every time I come across the money and time to boost or build I think to myself why? The car is already ludicruously fast for a family car. The tires don't ast very long as it is and the fuel economy is now mediocre. During Street driving 90% of the time your car is below 4000 RPMS. so tune for that, and whatever the top number is it will be good enough. torque wins races HP sells cars. .
A custom tune could improve your gas mileage! and I agree that you don't need to put crazy amount of money on a family car which you don't rev past 4k rpm..it totally make sens. But it's HP actually that wins race as it make you go fast.. few exemple: golf TDI (torquier) < golf R (faster) , euro Civic 2.2Ldiesel (torquier) < Civic SI 2L (Faster), Harley davidson (torquier) < CBR1000 (faster) , F150 3.0L diesel (torquier) < F150 5.0L coyote(still faster) etc.. Torque move the mass (great for hauling) and HP make the MPH (great for racing) so let's say two same car (same weight) but one is 200hp/100tq and the other is 100hp/200tq.. the first one will ALWAYS be faster in a race. Hope that help, Cheers!
@@benjbsn2429 I actually did spend what most would consider crazy money, I just didnt go FULL SEND. The gearbox has been rebuilt with RSX-S gears, the engine is from a JDM accord type-s, it has a competition flywheel, clutch, header and tune. sitting on continental 235/45R18 tires. It really was not cheap. I just ordered new RDX injectors due to mine being almost 20 years old now and well I'm maxing them out. THe GOLF R has 295 ftlbs of torque with the Golf diesel being 236ft'lbs, the harley weighs double what the CBR does. The coyote is 5.0 L, the diesel is 3.0, you are mistaken. The vehicles you compare are tuned for different purposes, its apples to oranges. WHat you are describing comes from the transmission type (auto vs man), gearing, cam timing, intake manifold design and the exhaust restrictions, not wether the car is"torquey" or not, I didn't say I don't rev past 4K, what I meant with the 90% comment is that when driving on the street you almost never have to downshift this car (unlike a b16a for example) you can cruise at 2000 mash the throttle and you are off to whatever the public road allows. About HP and torque, that is a misconception. When you see the revs climb and you feel it.. THAT IS TORQUE, when you shift at redline and the tires spin when you get back on it and the RPMS don't drop, THAT IS HP. HP is just sustained torque, a broader torque curve, properly geared, wins the race due to the TORQUE being MORE available in a broad range of RPMs. super high RPM power is "useful" but the engine is only capable in a very narrow range. The ideal Road car in my opinion has as much HP as possible, however without sacrificing the nominal torque. a simple cam change on my k24a i lost 8 HP and gained 10 ft/lbs and the car feels MUCH faster. It already had a decent amount of HP, but it really felt slower than a k24a3 below VTEC. I guess It really depends on what you mean by racing. Drag racing is pretty much the only type where HP wins consistently. But you must also remember that limiting or unleashing HP can be as simple as using a restrictor plate. However adding torque can only be acheived by increasing port velocities (reducing HP) or enlarging/mechanically tuning the engine. (all motor) So some race cars (RALLY CARS) have a mountain of torque but it drops off abruptly. why would the manufacturers do this??? to WIN without breaking the HP limit. My "restriction" is that the engine does NOT do as much past 7K. Big deal. THE SECRET SAUCE. When I had the A2 cams installed the peak torque was 187 at 4600 RPMS. with my new setup I have the 197 ftlbs peak at 5200 RPMS (Almost 200 HP at 5250 FTW) . Lower RPM CAMs WITH i-VTEC bring the torque peak HIGHER!!!!! with more available below, this is why the car feels faster. It has more torque than a 3.0 V6 Taurus The peak torque doesnt carry on past 5500 however it still has plenty to go. Peak HP is 236 at 6900. lol Things have changed alot from the days of tuning my ls-vtec and aiming for the moon, that is for sure. If you compare mine to a turbo car, I'm using a SMALLER turbo that builds MORE BOOST. VS a LARGER TURBO running LOW BOOST. Thicker legs don't run as fast but man do they haul a$$.
This is why the high majority of the builders that work on civics in Japan, especially Osaka,they love keeping their civics NA regardless of the engine type. Just good old full engine builds and tunes, very reliable as well.
Depending on your application it’s actually better if you are just after power then turbo is the only way but for circuit racing supercharger is the best option
Damn I am so stoked you guys did this was a little bummed it was a Type R rep in the beginning because I think that means absolutely has to be NA HAS TO BE !! I thought maybe supercharged might make that extenuated but NA is best you guys know!!
I've become a lot more mindful of sticking to an intended purpose for a car as I've gotten older. My daily, turbo E46 has a respectable amount of power for the streets. But not enough to overpower the chassis/tires. It's still enough to play with the Hellcats and ZL1s though 😅
I sold my Type R that was making 420 whp to get back into another 9th gen civic si for this EXACT reason. 400whp is lot more power than what the internet wants people to believe. Especially in a light car. It's really hard to find the space on roads to enjoy that power, and when you do enjoy that power.... it goes from 40-jail time speeds very quickly lol
The old motor setup is great for swapping into rear wheel drive cars like the lotus Elise, mr2, and such. When you're sticking with front wheel drive setups, there are unfortunately limitations.
I went from Kraftwerks to NA on my 8th gen coupe and although I miss the power and speed of the Rotrex kit I love my NA set up now, it still has nice torque, it's feisty and it grips like a dream. This is my daily and I'd rather have reliability and fun power than more power and problems, guess it's a middle age thing🤷🏾♂️🤣
there's tons of times I think less power is the right power. unless the objective with a build is to compete or display, cars are almost always best balanced and enjoyed with near-stock power.
Great choice. I didn't like the idea of having to cut out holes in the hood to fit that supercharger and also never liked staggered wheel/tire setup. Now it's more suitable for the streets like you've mentioned; more practical in a good way. Maybe fix that hole on the hood and a more subtle spoiler and it would be perfect. Love watching you guys wrench on the Hondas! PS. noticing a bit of rattling noise in idle.
I think it was a great decision. If not mistaken, you were slightly limited on the rpm range with the supercharger, which was a little anti-honda 😅 now you have all the rpms ✔️
Superchargers only exist to be used where a turbo doesn’t package well or at all. Every short coming or weakness of a centrifugal supercharger is in the area a small displacement 4 cylinder needs all the help it can get. Boost will be nearly linear with engine RPM. Hence why your HP line is at nearly a 45degree angle across the range. Stock compression/internals dictates a low peak boost limit. That 8lb pulley at 7.5k rpm is in theory and hopes 4lbs at 3750rpm. A peaky power spike for across the tail end of power band would definitely suck everywhere but the strip. On a lower rpm healthy displacement V8 they feel and perform awesome. I can almost guarantee a properly spec’d turbo/engine setup would never be tossed back for stock.
As a older Honda owner still playing with these cars. I have tossed around the idea of supercharging my 6-speed Tsx or swapping in a J37. Seems sacrilegious to remove the K24a2 but making 300 whp NA with a J37 without opening up the motor is so appealing. Especially from a reliability and daily driver point of view. Showing my age….😂
The best setup was the CT Engineering or old school Jackson Racing Eaton/M62 root style superchargers. Anywhere from 280-350whp depending on other mods/cooling. Its very simple AND the old Eaton units are as reliable as the Honda motor itself.
Ive found myself in this state of mind. My k swap is plenty but I want more at times. Not in normal driving situations, its perfect there. Thought about trying nitrous.
I am a 34yo petrolhead/car enthusiast and i totally agree with the NA choice. Its reliable and fun to drive. You can track it on Sundays, you can go to Walmart, you can take the kid to karate lessons, you can have fun on twisties on the way home in the afternoon, you can commute to work. Every time you will have a big smile on your face😊😊
I feel you could've gone for some 3d printing on this episode. Hood vent is right next to intake plenum. It could make for a short run and some proper intake noise.
I wanted a krafwerks sc for my DC2 for the longest time but ended up having King Motorsports build me a spicy 84.5mm bore b18c1 that makes 240whp/161wtq on e85. I am very happy I went the NA route, as it’s more than enough power for a good time! K power in a B series package and it just fits the character of the car perfectly.
As an old school vtec connoisseur, and also owning a FK8 type R, I can honestly say I miss that old vtec kicking in. I'll jump in my 9th gen Si once and a while just to rip some tec even though it's slow as hell compared to the FK8. Fully understand the reasoning behind removing the supercharger. Cheers boys.
Wait so you miss the old school vtec since the fk8 only has 1 side exhaust only vtec so you hop in a 9th gen Si which also has 1 side intake only vtec? Lol
@@d0mochi lol. You don't hear the vtec in the fk8 at all. Listen, I've had all the vtec motors you could have, h22 b18c b16b k20a2 k24a2 etc...the vtec still pops in my 9th gen despite only the ex. having vtec. I just miss the old na vtec that's all. No need to be saying things like your comment.
For power I always think turbo is the way to go, but 240 HP is great amount of power for a trackday/street car. I think that car would do well with some 245 tires atleast for trackdays.

@@mursetvlogs5717 They are going to sell it, and make more money selling the SC separate. Probably
@@dancarlos1216 ooo, yea that makes sense too. I figured a lot of their projects they always end up selling anyway since you never see them again
Why would I buy a civic to pedal it and shortshift? I want to be matted and banging gears every single drive.
I’m of the mindset that i should have gotten better with a crv all wheel drive setup with the supercharger,maybe that should be another video suggestion
AWD supercharged making 380 would be really rowdy 🔥
Way too complex, expensive and heavy. All they needed was a 255 square setup on some nice 300 tread wear tires and maybe lowering the boost a bit if required.
@@CrossWindsPat 255/35R18 200TW tires + add an external wastegate on the charge pipe plugged into a 4-port solenoid (boost by gear setup) Problem solved ✅
As a fa5 owner and 42 year old I still want the SC lol 😂
I had a 5th gen Camaro, did normal bolt on and really enjoyed the car, put a supercharger on and never really enjoyed it after. It was a blast in a straight line but it took the sportiness away. I drove it to the dealer with the mods all removed to trade it and actually missed how the car was in stock form.
Agree with the change back to n/a. So much more that can still be improved, not just acceleration but the whole dynamic of things.
I'm 43 & have a fwd SR20DE+T . I like the sounds the turbo🐌 makes......stututu🙂. Doubling the hp made the car more fun to drive.
Spent the day at TMP only to get home to watch some Speed Academy!
More Power = More Problems. Just a fact. The more strain you put on parts to sustain that power, the lower the lifetime expectancy. And the other train of thought... Driving Overpowered cars = Chore .... Driving Underpowered cars = space to have fun.... not running out of road or fighting for traction.
Yup
It’s already been proven in multiple videos that the Kworks charger did not give people issues at 20k+ miles.
Wisest decision ever. I build my K20 without the k24. Got the Brian crowder light weight striker, 87mm pistons, BC stage 3 cams. Running 2.2L. Having the extra power and torque balancing with the cars setup it’s super fun to drive. I’d post pics but don’t think I can on here.
My setup is FD2R and live in Japan. My numbers were 260hp and 178
Glad to see you guys thriving up North. Congrats on nearly 650k subscribers. I always say add power until you reach the limits of the chassis/tire. With light FWD cars on street tires, that's a pretty low limit. 250-300 whp is probably that limit for most people. Even the newer CTRs with much better suspension design start to become a handful on street tires above 350-400 whp.
Not surprised at all; I had a crx back in the day that made 300whp and in a street race would get beat by anything from a dig. Highway and the track with r compounds was different but 245whp on that chassis sounds perfect. 👍
Honestly I love the 8th gen civic si and seeing you build the supercharger set up was awesome and I’m glad I’m now seeing an all motor set up really love seeing this car on camera
Such a great car! I love my 197ish hp 8th gen Si coupe. Just put Micheline Pilot Sport 4S tires on and really enjoying it.
It's pretty nice being able to get traction in most every gear, instead of half way through 3rd and on. Guess I need to get a K24 bottom end now.
Saturday morning coffee with Speed Academy makes it a good morning for also this middle aged enthusiast ☕
Also as a middle aged enthusiast I too agree, sometimes less is better. Waiting patiently for that Miata build.
You guys should install an ecu controlled wastegate on the charge pipe. So your tuner can limit you boost by whatever values he wants. Like limit it per gear, limit in per mode setting, etc.
Seen a couple guys doing this lately and it's really neat
Where have you seen this? I’m interested for my fg2 with a kraftwerks .
41 yrs old, just got a FA5 7 months ago, i also have a Fb6 si as well. Just simple bolt ons and a tune on either one of them is enough. 😊
Definately true, If you are drag racing you need the power. For daily driving I've been at ~240hp 197 ft/lbs Crank in my CL9 for 8 years now, every time I come across the money and time to boost or build I think to myself why? The car is already ludicruously fast for a family car. The tires don't ast very long as it is and the fuel economy is now mediocre. During Street driving 90% of the time your car is below 4000 RPMS. so tune for that, and whatever the top number is it will be good enough. torque wins races HP sells cars. .
A custom tune could improve your gas mileage! and I agree that you don't need to put crazy amount of money on a family car which you don't rev past 4k rpm..it totally make sens. But it's HP actually that wins race as it make you go fast.. few exemple: golf TDI (torquier) < golf R (faster) , euro Civic 2.2Ldiesel (torquier) < Civic SI 2L (Faster), Harley davidson (torquier) < CBR1000 (faster) , F150 3.0L diesel (torquier) < F150 5.0L coyote(still faster) etc.. Torque move the mass (great for hauling) and HP make the MPH (great for racing) so let's say two same car (same weight) but one is 200hp/100tq and the other is 100hp/200tq.. the first one will ALWAYS be faster in a race. Hope that help,
Cheers!
@@benjbsn2429 I actually did spend what most would consider crazy money, I just didnt go FULL SEND. The gearbox has been rebuilt with RSX-S gears, the engine is from a JDM accord type-s, it has a competition flywheel, clutch, header and tune. sitting on continental 235/45R18 tires. It really was not cheap. I just ordered new RDX injectors due to mine being almost 20 years old now and well I'm maxing them out.
THe GOLF R has 295 ftlbs of torque with the Golf diesel being 236ft'lbs, the harley weighs double what the CBR does. The coyote is 5.0 L, the diesel is 3.0, you are mistaken. The vehicles you compare are tuned for different purposes, its apples to oranges. WHat you are describing comes from the transmission type (auto vs man), gearing, cam timing, intake manifold design and the exhaust restrictions, not wether the car is"torquey" or not, I didn't say I don't rev past 4K, what I meant with the 90% comment is that when driving on the street you almost never have to downshift this car (unlike a b16a for example) you can cruise at 2000 mash the throttle and you are off to whatever the public road allows.
About HP and torque, that is a misconception. When you see the revs climb and you feel it.. THAT IS TORQUE, when you shift at redline and the tires spin when you get back on it and the RPMS don't drop, THAT IS HP. HP is just sustained torque, a broader torque curve, properly geared, wins the race due to the TORQUE being MORE available in a broad range of RPMs. super high RPM power is "useful" but the engine is only capable in a very narrow range. The ideal Road car in my opinion has as much HP as possible, however without sacrificing the nominal torque. a simple cam change on my k24a i lost 8 HP and gained 10 ft/lbs and the car feels MUCH faster. It already had a decent amount of HP, but it really felt slower than a k24a3 below VTEC.
I guess It really depends on what you mean by racing. Drag racing is pretty much the only type where HP wins consistently. But you must also remember that limiting or unleashing HP can be as simple as using a restrictor plate. However adding torque can only be acheived by increasing port velocities (reducing HP) or enlarging/mechanically tuning the engine. (all motor) So some race cars (RALLY CARS) have a mountain of torque but it drops off abruptly. why would the manufacturers do this??? to WIN without breaking the HP limit.
My "restriction" is that the engine does NOT do as much past 7K. Big deal.
THE SECRET SAUCE. When I had the A2 cams installed the peak torque was 187 at 4600 RPMS. with my new setup I have the 197 ftlbs peak at 5200 RPMS (Almost 200 HP at 5250 FTW) . Lower RPM CAMs WITH i-VTEC bring the torque peak HIGHER!!!!! with more available below, this is why the car feels faster. It has more torque than a 3.0 V6 Taurus The peak torque doesnt carry on past 5500 however it still has plenty to go. Peak HP is 236 at 6900. lol Things have changed alot from the days of tuning my ls-vtec and aiming for the moon, that is for sure.
If you compare mine to a turbo car, I'm using a SMALLER turbo that builds MORE BOOST. VS a LARGER TURBO running LOW BOOST. Thicker legs don't run as fast but man do they haul a$$.
this content makes me miss my FBO FA5 so much.. had it tuned by Nick as well, great guy!
I always thought that the supercharger wasn't the correct fit for that car. I really think that this is the perfect setup for this car.
That’s what the k24 bottom end is for. TORQUE!!! Adding the k20 head for high end power and you have consistent power throughout the power band
I'm still at the beginning of the video and I already agree. Nothing like NA. Beautiful engine bay. Compliments the cars looks.
Always worth it! Had an 8th with CTEngineering supercharger kit (roots) and that thing whined!
Nothing like a N/A vtec k series , that’s enough great power , kids these days think 500whp is low is crazy
K20/24 way to go.. it’s the setup in my 03 rsx-s.. with 2.2 dc cams and e85 with dc Creations intake I made 256 and it’s crazy quick!
Pete's genuine reaction on that first pull after the dyno says it all! The perfect Civic maybe?
that hybrid intake is killing it! I have hybrid CAI on my K24 EP3 & it is awesome
For not being a true FD2, you guys did it the right way to being close to identical to a true FD2. I would LOVE to own one.
on that config 200 torque would be just the perfect numbers to match that NA HP, Love the build tho great looking Si
As a 40 year old owner of a K20Z3 swapped EK, I say NA just works. I love this take, great episode!
Also approaching middle age and power is overrated when you consider worry free driving enjoyment
I love not ever looking at my AFR gauge :)
Approaching middle age is definitely overrated
@@ChoPi-Eww As someone middle-aged, I'll co-sign this statement. 🤣
lame
Got rid of that rotrex before that shaft snapped which is always a plus. Tons of these rotrexes are seeing the shaft snap off for some reason
Aaaand superchargers are expensive asf 😂
This is why the high majority of the builders that work on civics in Japan, especially Osaka,they love keeping their civics NA regardless of the engine type. Just good old full engine builds and tunes, very reliable as well.
Depending on your application it’s actually better if you are just after power then turbo is the only way but for circuit racing supercharger is the best option
I would LOVE to do this to my 06 k24 accord. Itd be such a sweet sleeper and plus it looks so beautiful under the hood
I’m 26 and i turned down my 430hp AWD rsx down because I didn’t need that power on a street daily driver.
I hope you do a SW20 MR2 some day.
Me too buddy me too, I have one myself.
Simplicity works every-time, i prefer that engine setup with a set of drag cartel stage 4 camshafts and head package.
Dave great job !! Love it’s all motor sounds really good it’s more street able to enjoy as a daily driver! Keep up the great videos
Damn I am so stoked you guys did this was a little bummed it was a Type R rep in the beginning because I think that means absolutely has to be NA HAS TO BE !! I thought maybe supercharged might make that extenuated but NA is best you guys know!!
What a beautiful build! Glad the injectors worked out well!
Great choice going back to N/A. Perfect amount of power!
Teaching the car to talk. Love the Civic, great series.
I've become a lot more mindful of sticking to an intended purpose for a car as I've gotten older. My daily, turbo E46 has a respectable amount of power for the streets. But not enough to overpower the chassis/tires. It's still enough to play with the Hellcats and ZL1s though 😅
I sold my Type R that was making 420 whp to get back into another 9th gen civic si for this EXACT reason. 400whp is lot more power than what the internet wants people to believe. Especially in a light car. It's really hard to find the space on roads to enjoy that power, and when you do enjoy that power.... it goes from 40-jail time speeds very quickly lol
The old motor setup is great for swapping into rear wheel drive cars like the lotus Elise, mr2, and such. When you're sticking with front wheel drive setups, there are unfortunately limitations.
The only thing I regret about this build is the race seat and the rear wing. This is your build it's up to you.
I went from Kraftwerks to NA on my 8th gen coupe and although I miss the power and speed of the Rotrex kit I love my NA set up now, it still has nice torque, it's feisty and it grips like a dream. This is my daily and I'd rather have reliability and fun power than more power and problems, guess it's a middle age thing🤷🏾♂️🤣
there's tons of times I think less power is the right power. unless the objective with a build is to compete or display, cars are almost always best balanced and enjoyed with near-stock power.
Great choice. I didn't like the idea of having to cut out holes in the hood to fit that supercharger and also never liked staggered wheel/tire setup. Now it's more suitable for the streets like you've mentioned; more practical in a good way. Maybe fix that hole on the hood and a more subtle spoiler and it would be perfect. Love watching you guys wrench on the Hondas!
PS. noticing a bit of rattling noise in idle.
The 8th gen really looks so good with a big old wing.
My time attack car is down for a while…it might “lose” its wing to my daily.
I think it was a great decision. If not mistaken, you were slightly limited on the rpm range with the supercharger, which was a little anti-honda 😅 now you have all the rpms ✔️
What a great result!!
Have to say was expecting nick to flick the Honda badge and say in ASMR voice “Honda” when he was strapping it down 🤣
Superchargers only exist to be used where a turbo doesn’t package well or at all. Every short coming or weakness of a centrifugal supercharger is in the area a small displacement 4 cylinder needs all the help it can get. Boost will be nearly linear with engine RPM. Hence why your HP line is at nearly a 45degree angle across the range. Stock compression/internals dictates a low peak boost limit. That 8lb pulley at 7.5k rpm is in theory and hopes 4lbs at 3750rpm. A peaky power spike for across the tail end of power band would definitely suck everywhere but the strip. On a lower rpm healthy displacement V8 they feel and perform awesome. I can almost guarantee a properly spec’d turbo/engine setup would never be tossed back for stock.
As a older Honda owner still playing with these cars. I have tossed around the idea of supercharging my 6-speed Tsx or swapping in a J37. Seems sacrilegious to remove the K24a2 but making 300 whp NA with a J37 without opening up the motor is so appealing. Especially from a reliability and daily driver point of view. Showing my age….😂
8th gens hook really well. NA is Best! Don't need a lot horsepower to have fun. Love the content guys!!
"it's crazy how bad the roads are"
*laughs in Louisiana*
I'm surprised yall don't get tire/wheel allowance from the state for how bad it is. Anything south of Interstate 20 is "F"ed.
The best setup was the CT Engineering or old school Jackson Racing Eaton/M62 root style superchargers. Anywhere from 280-350whp depending on other mods/cooling. Its very simple AND the old Eaton units are as reliable as the Honda motor itself.
Ive found myself in this state of mind. My k swap is plenty but I want more at times. Not in normal driving situations, its perfect there. Thought about trying nitrous.
I am 100% with you! The builds with 600hp for the street that spun all gears even with boost by gear are just not my thing anymore.
We're not just Honda guys, we're about to K-swap a Miata! lol
Have you seen the J series miata setup?
I want to K Swap my Mazda Protege, there is a handful of guys that already did it and say its almost like kswaping an EK,
There really is a sweet spot for usable power in a street car, especially a front wheel drive one.
I am a 34yo petrolhead/car enthusiast and i totally agree with the NA choice.
Its reliable and fun to drive. You can track it on Sundays, you can go to Walmart, you can take the kid to karate lessons, you can have fun on twisties on the way home in the afternoon, you can commute to work. Every time you will have a big smile on your face😊😊
I feel you could've gone for some 3d printing on this episode. Hood vent is right next to intake plenum. It could make for a short run and some proper intake noise.
I thought y’all sold this car. Nice to see you mod it make it an awesome daily.
EF vs EG vs FD shoot out?
Yes!! @speedacademy
I wanted a krafwerks sc for my DC2 for the longest time but ended up having King Motorsports build me a spicy 84.5mm bore b18c1 that makes 240whp/161wtq on e85. I am very happy I went the NA route, as it’s more than enough power for a good time! K power in a B series package and it just fits the character of the car perfectly.
Even though I am young I get what he is talking about, driving a slow car fast is way more fun, because you can actually push it’s limit on roads
As an old school vtec connoisseur, and also owning a FK8 type R, I can honestly say I miss that old vtec kicking in. I'll jump in my 9th gen Si once and a while just to rip some tec even though it's slow as hell compared to the FK8. Fully understand the reasoning behind removing the supercharger. Cheers boys.
Wait so you miss the old school vtec since the fk8 only has 1 side exhaust only vtec so you hop in a 9th gen Si which also has 1 side intake only vtec? Lol
@@d0mochi lol. You don't hear the vtec in the fk8 at all. Listen, I've had all the vtec motors you could have, h22 b18c b16b k20a2 k24a2 etc...the vtec still pops in my 9th gen despite only the ex. having vtec. I just miss the old na vtec that's all. No need to be saying things like your comment.
@@JDM_Jeffro it’s the boost. I’ve had an s2000, fk7 and now an fa5. Even those f20c and k20z3 you don’t hear the vtec once you get forced induction.
For power I always think turbo is the way to go, but 240 HP is great amount of power for a trackday/street car. I think that car would do well with some 245 tires atleast for trackdays.
I think you made the right move. No point in having so much power that you over cook the tires.
If anyone wants to do rdx injectors you can get scion tc injector plugs and just repin them. Much better then splicing your harness
I miss multiple videos per week from you guys. I’m guessing life has gotten in the way
