If you look at lower powered cars at the nurburgring for example. They tend to stay away from wide wheels/tires because of the mass. People who run E36 M3’s actually go quicker on 235’s than 245’s for example, and they have 140hp more than this RX8. I believe the E36 M3 stock motor record BTG is done on 235/45 Dunlop DZ03G. So having 275’s on a 185hp car probably isnt the smartest.
@@km6832I’m sure it was a control tire test. Tire width should be scaled to vehicle weight and power. A sticky, narrower tire will be faster than a wider, less sticky tire in most cases
I just watched two men add a lot of drag to an underpowered car. I hope there aren't a lot of long straights on this track. Otherwise this rx-8 is going to get smoked.
Adding downforce to slower cars is not so detrimental. The reason why is because underpowered cars can't reach the speeds where the drag matters so much to begin with. Wind resistance does not scale linearly, so, drag matters a lot more the faster you go
doesnt have a spare only the tire repair kit from factory. rear seats weigh almost nothing. a big weight saving would be to replace the driver seat with the passenger seat because the passenger seat isnt elecric and thus is a lot lighter
@JorgeMartinez-iq2tc I had 245s on my 8 and you had to work to break them free and they were firehawk Indy 500s. These on Ben's car won't budge and be heavier. Imo. I wouldn't have gone above 245
Get a tune from a pro tuner and tune it on E85, I have owed Rx8’s for years. You can definitely get 220+ whp. Also lightweight flywheel crank pulley, racing best intake and sway bars. She’ll be a blast to drive
Honestly I don’t think the rx8 stands a chance, I was rooting for it at first but the power and weight difference between it and the s2000 will be quite evident on track. Was kinda hoping the Bridgeport gave her a little more juice than that
Dont get why people think a s2k is that much quicker best motoring had a rx-8 A Spec kinda destroy a s2k around a track especially around the turns the honda couldn't match its handling.

It might be underpowered, its not really that much heavier as everyone makes it out to be but its suspension design, geometry and amazing balance on the limit give driver the confidence to push but also provide a tonne of lateral grip.

When sanding exhaust flanges you should always use a belt sander bigger than the flange. Using a die grinder like that will just make the flange surface not be flat, causing a leak.
Renesis can handle 55 shot of nitrous all day. He should throw on a 10lb bottle which would be like 2 minutes of wot. Then the cars would be even power wise
...and it's mounted poorly, they haven't even tested it. It will probably just add a ton of drag and no downforce + heaps of weight lol. I wish them the best though.
Expected as much from the bridgeport. A built up streetported motor usually nets more power. Some people have even seen 220+whp N/A that way, while retaining better power in the low-mid rpm range. It's a different rotary so it's gotta be treated as such. One of the best mods you could do is a full free flowing exhaust system, decatted. That alone with probably net you the most gains. The stock intake is already really good from factory, but I think there's some aftermarket intakes on the market that will net you a couple more hp. Another thing to note with these motors is the exhaust port, it's very restrictive from factory and there's not much room to port it due to water galleys/jackets running real close to em. Small cleanup/porting/smoothing can be done and net a couple HP, along with small cleanup on the intake runners but you gotta be careful. Some companies such as Racing Beat have porting templates available, and although it's a small increase it does help to gain a little more power. Better ignition coils net a teeny bit of power from stock as well, BHR coils are popular. This is all from research, I have never owned a renesis I'm just a fan of them.
For you not to have one that's pretty good research. All you're missing is a lightweight flywheel from racing beat steel braided clutch line and exedy HD clutch.

It will allow him to carry more speed in the turns where as Asian Ben’s car will have to slow down. S2000’s suffer from snap oversteer so (A)Ben will need to go slower in the turns. That’s the only way the rX8 will be able to stay competitive.

@easydayez true bridge port cant extend port you can. RUclips has habit of calling all types of porting o a rotor bridgeporting. If properly bridgported the forced induction causes porblems due to the overlap. not saying you cant do some form of porting because huge power rotors are always ported but they pretty specific to application. Na vs turbo you approach it differently. But loads of examples of people doing the wrong thing on youtube for sure. Doesnt mean their engine didnt go kaboom a week later. Bridgeporting provides the best results for na. Plus this 13b type not fantastic for turbo to begin with.

Is supercharging an Rotary a thing? can that be done? has it been done... hmmm...
I do really appreciate you Ben, but getting rid of some parts of the interior would have been much better than adding aero, lowering center of gravity too! Buy some pole positions and get rid of that +200lb interior asap, you will win that way (and need you to do so)
Forced induction + alcohol please. Rotaries love methanol injection or ethanol for fuel for the knock resistance and cooling. Rotaries don't cool the combustion chamber well since intake and exhaust take place in different parts of the housing.
I did love the Forza wing line. Big laugh for that no doubt. But I agree with Mark, you need to do more. No replacement for displacement, needs more power. My tuned Golf might give you a run for your money as that sits now.
Looks like it'll handle well into a sweeper at 100mph, but it's gonna need such a long straight to get to that speed. And a 235 track tire would've been the move, a 275 is a lot of unnecessary unsprung weight to add for such little power. Plus a wider tire adds frictional resistance which slows you down in straights.
I personally can't wait to see the race! I love both cars so iam not siding on one or the other. But my heart senses a roadtrip in them,atleast I'm hoping for it! Track is why I subscribed to G&G,but its been a good minute since we got a roadtrip episode!
Wider isn't necessarily better for tires. Tire width should be optimized for operating temperatures for the specific car. Tire temperature under operation depends on the force per its contact area. So a narrower tire will heat up more than a wider one. Because tire rubber has an ideal operating temperature where its friction coefficient is at its highest, this means that for a light weight car you may get more grip from a medium/narrow tire than a really wide one. The cars weight struggles to heat up the wider tires to its ideal temperature. Naturally you can also go too far the other way where the tires get too hot. There is also a common misconception that friction depends on surface area. But it doesn't. As surface area increases, contact pressure decreases if mass is constant. So in reality tire friction only depends on vehicle mass and friction coefficient. Area can effect the friction coefficient as i described above, but has no direct impact. The same rubber at the same temperature will provide the same grip in a 200mm tire as with a 275mm tire.
Everybody ragging on the aero... :D A low power car benefits from aero a lot. A 9 Lives Racing wing on my 170 whp MR-S cut 3 seconds off on a 90 sec track. Every single braking point has a HIGHER speed with the wing due to higher cornering speed, earlier throttle and thus, faster exit from the corner before. Also, the Torsen diff doesn't slip any more, meaning yet earlier throttle at the exit. Depends on the track, of course, but low power cars will not reach the point where drag kills your top speed. So I am more than certain the RX-8 is faster with the added aero. The 275's, on the other hand...
The Renesis, the answer to can you make a rotary clean running and reliable. Answer, not really. The exhaust ports are the killer with this engine as it bakes the casing seals.
Many people stating the rx8 won't push the wheels but forget hit import in japan did many many builds that showed the rx8 handling incredibly well with tires alone.
It’d be epic to see a factory renesis 13b make more power while utilizing a turbocharger. I’m just hoping that the Ben Thorne’s Ford Escort will get another chance to make a road trip. As uncommon to many better known platforms as this is to modify it’s what got me hooked for a long time following you guys at gears and gasoline. It’s definitely awesome seeing that in recent times the rx8 is finally getting more popular and recognized by us enthusiasts
You're set up for serious autocross as a track driver. Good luck. Some notes. 275s are fine as I've seen up to 315 under those fenders. I would have put them on 17s, though. S long tube header would have been better. Lightweight flywheel as others have mentioned. Not much torque means lightening any rotational load as much as possible. Lastly, take the cat out and use a single exit exhaust, and she'll fly just fine. Noisy, grippy, def not the fastest, but it's a damn go kart.
Well Ben. You could have Easly fixed the flex issue of the trunk lid by installing struts inside the trunk and distribute the load to a wider area without adding a lot of weight. Just check how you can transfer the down force load from the trunk lid to the inner part of the trunk.
Strip down the interior. All they need is the driver seat and door handles. Passenger, rear seat, all the panels sound dampening, anything in the trunk, spare tire. Also in the trunk from the inside add some rods so the wing mounts rest on them and have them rest on the trunks floor. That will allow you to run more down force.
This comment is the winner. Gotta gut the rx8. Drop the weight by 500 pounds will give it shot. Balance the weight if possible. Might need reinforcements.
I only do, but for the sake of the RX8. The 8 will be tge better handling car at the limit guaranteed because they're exceptionally easy to drive all the way to the limit, but it doesn't make enough power.
You can add about 30% or more front downforce with tunnels/diffusers in it. And I'd close that gap up and vent the hood if you want the front to really work. Also people in the comments stop pretending like you know what you're talking about with the 275 wide tires. A wider wheel and tire combo will almost always be faster around a road course. Very obvious you're not racing a road course car. Nobody would ever say a narrower wheel and tire will be faster. It's really that simple. Wider is almost always faster. Even on 100 hp car. Grip is always a limiting factor unless it's an oval or huge insanely long straight track. Even cota a 275 would be faster than a 235 or 245
Love it awesome I'm also prepreping my rx8 for track use and the builds is almost identical,one thing Wich I found a lil odd that Eric didn't mentioned that a total rotary brake in is 1500miles so they only completed the bare minimum so idk maybe is for production porpoises but small Ben rx8 power is gonna increases cuz he is still in brake in period and the brand new housing ,apex seal and side seal still has to brake in properly so Ben if u read this u still have hope on the power department cuz u literally have all the bolt on mods on rotary for power so it should be around 215-220
Hedders in REV engine is really good designed. If RX-8 had be fastest as it can be, you should build lightest car you can, plus good driving position, good suspension with allignment, tyres and at the end add more lightness ;)
Ben is going to be running Honda s2000 with spoon engine, and on top of that, he just went into Harry’s and bought a t66 turbo with nos, and a motec exhaust system.
Watching the series in order, let me just say I have high hopes for the RX8, seen an Auto X RX8 build, also NA 1.3, and that RX8 was FLYYYINNGGG, one of the fastest cars at it's events. So I'm thinking even though the RX8 may be a little bigger, and engine a little weaker, the RX8 chassis and balance is very, very good from what I seen, so that's my prediction right now, I think it'll be competitive at least.
Around 2010-2012, some of my friends who owns an RX-8 tried pretty much all combinations of modifications except engine porting... The most power comes by removing that stupid cat and putting there a proper, single exit 76mm (3 inches) full exhaust. That gives the highest increase in HP. Second most critical modification is a lightweight flywheel. One of my friend's rx8 dynoed 206 whp with 76 mm single exit full exhaust, headers, lightweight flywheel and a tune (tune gave very little). So, if you really want to get some gains, no-cat and 76mm single exit full exhaust is kind of must. Yes it will be very loud bla bla... But at least 10whp is lost there otherwise... Found the video of the pull: ruclips.net/video/YnyFhFr-rVQ/видео.html
Yep, I was glad they installed a header, but leaving the stock cat and mid-pipe, I knew it was going to come in low for power. The Renesis' weakness is its exhaust ports! Do everything to make the exhaust flow well. That Bridgeport only made the problem worse. That poor stock cat is going to be melted before the end of their race.
I enjoy the video series on this RX8! The RX8 needs more love to battle a K swap S2000 with cams, ITB’s, headers, big brake kit, full tune by a know Honda tuner. Plus the added big aero is going to kill the RX8.
What gets me is a stock 86 beats these numbers, no wonder they became the new miata standard, and to tack onto that you can bolt on 400hp now with stock trans etc :)
I feel tire width should be selected for the right balance of minimizing rolling resistance and maximizing cornering grip. Same way of thinking for tire selection for na/nb miatas, they are usually faster on a 8” wheel with a 205 rather than a 225
I remember there being a lot of noise when the RX8 came out that it dyno's low became the ECU didn't see the front wheels rotating so it pulled back power. I think you're making more real power when the car is moving, maybe another 30 whp.
Winner of the race picks the next roadtrip destination! Loving this series so far 🔥
Take Mark along too
Yo it be great if our boys can do a roadtrip in a different country instead. UK? JAPAN? Somewhere right hand drive? It would be something new for them

Forced induction + alcohol please. Rotaries love methanol injection or ethanol for fuel for the knock resistance and cooling. Rotaries don't cool the combustion chamber well since intake and exhaust take place in different parts of the housing.
All that 7 HP gain to loose 20 HP in weight on a heavy pices of wood lol
To compliment that wing I also have an anchor that will pull you to the ground even more and increase grip further.
So happy to see Mr Rad helping out
I love these builds you guys have been doing lately with this and the dsm. You guys are killing it.
I did love the Forza wing line. Big laugh for that no doubt. But I agree with Mark, you need to do more. No replacement for displacement, needs more power. My tuned Golf might give you a run for your money as that sits now.
Looks like it'll handle well into a sweeper at 100mph, but it's gonna need such a long straight to get to that speed. And a 235 track tire would've been the move, a 275 is a lot of unnecessary unsprung weight to add for such little power. Plus a wider tire adds frictional resistance which slows you down in straights.
yeah rx8 needs to be at THAT speed for the aero to work well but its getting to that speed is the problem right now hehehe
Boy oh boy, I smell a future roadtrip with those two cars 😊
Such a creative genius, seriously!
I personally can't wait to see the race! I love both cars so iam not siding on one or the other. But my heart senses a roadtrip in them,atleast I'm hoping for it! Track is why I subscribed to G&G,but its been a good minute since we got a roadtrip episode!
On the curves you could take advantage! Good luck! RX8 team🦾
Something about mark throwing that crusty ah coil pack bracket back in made me wanna punch a wall
LOL budget meal build 😅
kinda expected a street race at the end, felt like a movie scene
Wider isn't necessarily better for tires. Tire width should be optimized for operating temperatures for the specific car. Tire temperature under operation depends on the force per its contact area. So a narrower tire will heat up more than a wider one. Because tire rubber has an ideal operating temperature where its friction coefficient is at its highest, this means that for a light weight car you may get more grip from a medium/narrow tire than a really wide one. The cars weight struggles to heat up the wider tires to its ideal temperature. Naturally you can also go too far the other way where the tires get too hot.
There is also a common misconception that friction depends on surface area. But it doesn't. As surface area increases, contact pressure decreases if mass is constant. So in reality tire friction only depends on vehicle mass and friction coefficient. Area can effect the friction coefficient as i described above, but has no direct impact. The same rubber at the same temperature will provide the same grip in a 200mm tire as with a 275mm tire.
Everybody ragging on the aero... :D A low power car benefits from aero a lot. A 9 Lives Racing wing on my 170 whp MR-S cut 3 seconds off on a 90 sec track. Every single braking point has a HIGHER speed with the wing due to higher cornering speed, earlier throttle and thus, faster exit from the corner before. Also, the Torsen diff doesn't slip any more, meaning yet earlier throttle at the exit.
Depends on the track, of course, but low power cars will not reach the point where drag kills your top speed. So I am more than certain the RX-8 is faster with the added aero.
The 275's, on the other hand...
I really WANTto like the RX-8... Such a beautiful unique vehicle!
It's an amazing car if you can accept the fact you will have to rebuild the engine. People don't understand how good the handling is
19:30 same reaction when a girl steps on the scale 😂
there was a japanese racer who said on the trach while racing: i hate heavy cars, and heavy chicks XD
"Not that"
YESSSSSSSSSSSSSS IVE BEEN WAITING FOR YOU TO BUILD THE RX8. This my cement the decision of me selling my civic and purchasing an rx8.
The Renesis, the answer to can you make a rotary clean running and reliable. Answer, not really. The exhaust ports are the killer with this engine as it bakes the casing seals.
Yup gotta port the exhaust
Many people stating the rx8 won't push the wheels but forget hit import in japan did many many builds that showed the rx8 handling incredibly well with tires alone.
I have never gotten something spoiled by a T-Shirt before…
And boy am I happy to have my hope confirmed!
You should toss on a lightweight flywheel for hehes and hahas to see how much more power you can free up
great content keep building the RX8!! love it man
I don't know why I love watching you make splitters so much. But, I do.
Get some hub centric rings for the wheels. It centers the studs in the lug holes so sockets wont rub and scratch the paint. It also reduces vibration.
It’d be epic to see a factory renesis 13b make more power while utilizing a turbocharger. I’m just hoping that the Ben Thorne’s Ford Escort will get another chance to make a road trip. As uncommon to many better known platforms as this is to modify it’s what got me hooked for a long time following you guys at gears and gasoline. It’s definitely awesome seeing that in recent times the rx8 is finally getting more popular and recognized by us enthusiasts
One sick looking Rx8.
You're set up for serious autocross as a track driver. Good luck. Some notes. 275s are fine as I've seen up to 315 under those fenders. I would have put them on 17s, though. S long tube header would have been better. Lightweight flywheel as others have mentioned. Not much torque means lightening any rotational load as much as possible. Lastly, take the cat out and use a single exit exhaust, and she'll fly just fine. Noisy, grippy, def not the fastest, but it's a damn go kart.
Man sunday cartoons are the best
That looks like a blast to drive. No idea how it’ll deal with the S10K, but it looks like a great time.
Well Ben. You could have Easly fixed the flex issue of the trunk lid by installing struts inside the trunk and distribute the load to a wider area without adding a lot of weight. Just check how you can transfer the down force load from the trunk lid to the inner part of the trunk.
Very excited for this series.
Keep up the builds guys! This is youtube gold 🥇
Strip down the interior. All they need is the driver seat and door handles. Passenger, rear seat, all the panels sound dampening, anything in the trunk, spare tire.
Also in the trunk from the inside add some rods so the wing mounts rest on them and have them rest on the trunks floor. That will allow you to run more down force.
This comment is the winner. Gotta gut the rx8. Drop the weight by 500 pounds will give it shot. Balance the weight if possible. Might need reinforcements.
I kinda want Asian Ben to lose for some reason 😂
He'd be cursing way too much.😅😅😅
Not me hahah that guy needs a break😅
Gotta put those stookie bros in their place. It's our only hope.
Same
I only do, but for the sake of the RX8. The 8 will be tge better handling car at the limit guaranteed because they're exceptionally easy to drive all the way to the limit, but it doesn't make enough power.
You can add about 30% or more front downforce with tunnels/diffusers in it. And I'd close that gap up and vent the hood if you want the front to really work.
Also people in the comments stop pretending like you know what you're talking about with the 275 wide tires. A wider wheel and tire combo will almost always be faster around a road course. Very obvious you're not racing a road course car. Nobody would ever say a narrower wheel and tire will be faster. It's really that simple. Wider is almost always faster. Even on 100 hp car. Grip is always a limiting factor unless it's an oval or huge insanely long straight track. Even cota a 275 would be faster than a 235 or 245
Should put the manifold on a belt sander or machine to flatten
I love RX8's, incredible design of the interior and exterior. Wishing you luck against the S2000!
I always love the rx8. this has become such a rad build. lets go bens
The "quick release" latches for the splitter, are the same latches used for ambulance doors. Just a fun fact, since I work on ambulances for a living
Also removing the knock sensor helps in making power in these engines as they're quite noisy internally causing some issues with higher rpm power.
Woke up randomly at 4am to see this posted yay
Love it awesome I'm also prepreping my rx8 for track use and the builds is almost identical,one thing Wich I found a lil odd that Eric didn't mentioned that a total rotary brake in is 1500miles so they only completed the bare minimum so idk maybe is for production porpoises but small Ben rx8 power is gonna increases cuz he is still in brake in period and the brand new housing ,apex seal and side seal still has to brake in properly so Ben if u read this u still have hope on the power department cuz u literally have all the bolt on mods on rotary for power so it should be around 215-220
Hedders in REV engine is really good designed.
If RX-8 had be fastest as it can be, you should build lightest car you can, plus good driving position, good suspension with allignment, tyres and at the end add more lightness ;)
so excited for this matchup 💯
Ben is going to be running Honda s2000 with spoon engine, and on top of that, he just went into Harry’s and bought a t66 turbo with nos, and a motec exhaust system.
"Rotary engine" and "indestructable" dont live in the same sentence
glass engines
idk who to root for both cars are beautiful!
I want to see Mark show up with his car and destroy both the Mazda and the Honda. hahaha
Watching the series in order, let me just say I have high hopes for the RX8, seen an Auto X RX8 build, also NA 1.3, and that RX8 was FLYYYINNGGG, one of the fastest cars at it's events. So I'm thinking even though the RX8 may be a little bigger, and engine a little weaker, the RX8 chassis and balance is very, very good from what I seen, so that's my prediction right now, I think it'll be competitive at least.
Around 2010-2012, some of my friends who owns an RX-8 tried pretty much all combinations of modifications except engine porting... The most power comes by removing that stupid cat and putting there a proper, single exit 76mm (3 inches) full exhaust. That gives the highest increase in HP. Second most critical modification is a lightweight flywheel. One of my friend's rx8 dynoed 206 whp with 76 mm single exit full exhaust, headers, lightweight flywheel and a tune (tune gave very little). So, if you really want to get some gains, no-cat and 76mm single exit full exhaust is kind of must. Yes it will be very loud bla bla... But at least 10whp is lost there otherwise...
Found the video of the pull:
ruclips.net/video/YnyFhFr-rVQ/видео.html
Yep, I was glad they installed a header, but leaving the stock cat and mid-pipe, I knew it was going to come in low for power.
The Renesis' weakness is its exhaust ports! Do everything to make the exhaust flow well.
That Bridgeport only made the problem worse. That poor stock cat is going to be melted before the end of their race.
I enjoy the video series on this RX8! The RX8 needs more love to battle a K swap S2000 with cams, ITB’s, headers, big brake kit, full tune by a know Honda tuner. Plus the added big aero is going to kill the RX8.
I just want an Rx8 more and more watching these videos
What gets me is a stock 86 beats these numbers, no wonder they became the new miata standard, and to tack onto that you can bolt on 400hp now with stock trans etc :)
I feel tire width should be selected for the right balance of minimizing rolling resistance and maximizing cornering grip. Same way of thinking for tire selection for na/nb miatas, they are usually faster on a 8” wheel with a 205 rather than a 225
Safe to say this car is gonna be Ben T's New track car. This and the Civic for different classes or if one is down
Shiny is fast. Adding stickers is even faster.
I remember there being a lot of noise when the RX8 came out that it dyno's low became the ECU didn't see the front wheels rotating so it pulled back power. I think you're making more real power when the car is moving, maybe another 30 whp.
do you recall if it were the forums from the time?
winning the race or not, this car looks wicked
"im gonna need more power if i want to beat a honda" are words no american has ever said until now
Rotary for the win !!
