For starters, the exhaust rubbing on the dyno roller WILL affect the results. Your power picking up on every run is probably due to the exhaust clearance itself as metal gets rubbed away and the rollers get easier to turn.
Pronounce it like the word noisy but instead of "s" use "z" letter Noizy, and can be written like you already did.... So i like your name idea for the Noi-Z 🙂
@@brokeblasian You don’t really notice chatter when you’re driving around. It is annoying in a drive-thru or at a red light because people think your car is about to blow up. Mine is also in a MK6 GTI.
@@brokeblasian you only hear the chatter really when your sitting at idle in traffic or something i have a stage 3 6 puck and 17 pound flywheel with full interior and and exhaust i cant hear it unless i have my door open worth a little noise forsure
A stock HR makes like 250 torque. So if your logic is correct it should have been making like 170 while the exhaust was scrubbing and then as it wore down it moved up to a max of 250 torque. But it didn't, it kept moving up and up to what, like 320 torque? I agree that problem was most likely the exhaust scrubbing, but there has to be more going on with the dyno and false readings not just that the exhaust wore down and the Zs true numbers came out.
When you first started it was dragging the exhaust really bad which was causing lag on the pull that made it look like you had less power each time you made another run it freed it up more and caused it to show more power each time
YOOOO What if the exhaust rubbing was slowing it down and the more you guys ran it and grinded through the less it restricted the rollers and therefore resulted in the slow increase in power XD
There is a good theory pointed out many others that the exhaust rubbing away is creating less resistance, thus reading more HP/TQ. Correct me if I’m wrong on this. Another theory I have is the Main Base Timing (MBT) is increasing on its own due to less knock threshold each run. Then relieving the airflow restrictions with the aftermarket intake leads to less knock threshold, therefore more timing automatically added for more power. I’m not totally familiar with tuning this platform, but from my (very) small experience with tuning Nissan/Infiniti, this is a viable theory.
Back in 2003 I bought a 350 when they first hit the US. Went to a dyno day that weekend. Made 237 wheel… (287 flywheel from factory I think is what Nissan reports/non hr) how tf are you seeing 300 and saying “yea it’s stock”. Factory the “hr” comes with 306 flywheel hp… how are you getting those numbers with zero drivetrain loss? I mean it’s cool 😎 just doesn’t compute. Thx for the content. ❤️
I think you're getting more power each run because you're wearing further through the exhaust and it doesn't have to work as hard to grind out the exhaust
Bro that dyno is wayyy off lol. 350z never make that much torque hr or de on an otherwise stock motor. Put Dj 370z on the rollers and compare. Something is definitely skewed.
@@TheRealMrRoyal larger resellers like Z1 have shipments coming in and out multiple times a day, and don't run live inventory because an item can go out of stock as quickly as it comes in, but will usually mark items that have an extended backprder.
I mess with the eyelids, I can't lie. It's already lready a vibe, especially from a few good feet away. If they're painted to match though... I think they will look muchhhhh better closer up...🤷♀
You have the intakes installed backwards. with aftermarket intakes, the MAF sensor is supposed to be on the bottom. That should help with the clearance.
Just think, these guys work on performance cars and parts all day and they didn't figure out that they were backwards and the exhaust was wearing causing more hp....now think what your local moron mechanic is doing to your car when you take it in to the shop. Work on your own shit lol
Hrs/vhr have good manifolds from the factory because they hold heat well, my car doesn’t actually run good until I drive it 20-30mins give or take. They like running in a sweet hot spot. Stock tune 07 HR
I feel like my Z lost a lot of low end when I installed the Z1 CAI. I am going to switch back to stock boxes w/ K&N drop-ins and the silicone post-MAF tubes. OEM+ish
If it has test pipes on it already without a CEL, it was more than likely tuned as they normally disable the post-cat O2 sensor in the tune. VQ's normally will do better with stock airboxes than the short ram intakes, but there is typically another bump when you make the jump from air boxes to long tube intakes so it sort of makes sense. If temp in the shop dropped too that would help the numbers too in my mind.
@@AudibleVisibIe you do realize the sun set in the time they installed the intakes right? Northern climates during the winter you’ll get a fairly drastic temp change once the sun sets but IAT’s directly effect timing so if it dropped 5-10 degrees, it could completely lead to better numbers.
Wondering if air temps affected the power as the sun went down, also wondering if the dyno is doing something funky to the numbers based on air temps. Almost feel like you should try stock airboxes vs the Z1 setup on Derek's dyno for a sanity check.
Get a roll of sticky backed 1/8 in. "hard" rubber for any contact points on the new intake. You can cut to size and the hard rubber will last for a while. I get it from Nashville rubber and gasket here and I'll bet there's some place similar in Conn. Z-bois about to ride!
More lenght and smaller diameter tube affect air velocity and usually generate more mid range torque. As long as the air is nice and cool should make more but if air gets hot propably makes less than on stock intakes
Damn jimmy you got the tiny boys should have went 3inch intakes tbh but at the end of the day like you said they was your only option and your drifting not looking for crazy horse pups!
I had a G37s and had both stillen and takeda intakes and only spot that was an issue is on driver side a/c line from the vibrations wore a hole thru my ac line but they worked great, im surprised it doesnt come with a bracket to hold the filters still, the stillen ones where definitely stiller because it has the one long filter
Diy twin turbo kit for the z , Johnny pipes can make headers or you can weld them yourself, and learn to weld , do something to make it quite, turbo charger , air to water intercooler and custom ecu, so the z will be quite with good power
TIP OF THE DAY:What you need to do is go down to a couple of your local firestations and ask if you can have their expired 2.5 inch firehoses and cut off the end couplers and you got yourself some of the best line insulation and wrap for around metal pieces to keep from rubbing.
I suggest a: Clutch Lightened flywheel Jim Wolf Cam Gears Jim Wolf Springs and Retainers Z1 Plenum Spacer Z1 Valve Guides Z1 Power Intake Mani Z1 Ported Lower Intake Mani
You wouldn't believe the amount of quiet you can get on a loud car by putting on a reduction down turn on the end of the muffler, and you could always remove it later when you get a proper exhaust. If you get an adapter to go from whatever the exhaust is 3" or 2.5" and bring it down to 2" and put a down turn on it, it's like 90% quieter its crazy. I have evidence on my own channel of doing this with a straight pipe car that was driving me crazy. It took away all the drone and the majority of the annoying noise.
Is it possible that the exhaust dragging on the dyno roller was creating drag & as it wore through, it was giving less & less drag, therefor showing higher numbers every pull. 🤔

+1 for this
Also the intakes are backwards thats why they fit funny and hit everything!
This is what I was thinking too.
Still not gonna be making that much power on a stock HR with exhaust, intake, and a tune
I came here to say this
I know it’s getting quieter at some point down the line but I feel like the name for this thing at the moment should be the Noi-Z cause it is LOUD
But it sounds like trash 🥴🥴🥴
Pronounce it like the word noisy but instead of "s" use "z" letter Noizy, and can be written like you already did.... So i like your name idea for the Noi-Z 🙂
that's fire
That's actually great.
@@Daveytoonasty didnt say it sounded fkn good he just said its noisy
Doggy throttle response comes from the 30 + lb flywheel. Aftermarket flywheel fixes that.excited to see this build
Yeah when I did the flywheel when I had mine, the throttle response was crazy good
@@synergy_gt5005 how is the flywheel chatter ? I want to go a lightweight flywheel but I don’t want to deal with the loud ass chatter
@@brokeblasian depends. I went ACT for mine and there was some chatter but it wasn’t unbearable by any means
@@brokeblasian You don’t really notice chatter when you’re driving around. It is annoying in a drive-thru or at a red light because people think your car is about to blow up. Mine is also in a MK6 GTI.

its wearing through the exhaust is why its gaining power
thats the first thing that came to mind yeah
Every pull had less resistance. Metal dragging on the rough roller surface acting as a brake.
The power kept going up because the exhaust was getting worn down and the rolling resistance was decreasing with each pull.
A stock HR makes like 250 torque. So if your logic is correct it should have been making like 170 while the exhaust was scrubbing and then as it wore down it moved up to a max of 250 torque. But it didn't, it kept moving up and up to what, like 320 torque? I agree that problem was most likely the exhaust scrubbing, but there has to be more going on with the dyno and false readings not just that the exhaust wore down and the Zs true numbers came out.
I prefer forced air intakes, but that's just me :D
Shutoff on the battery please. That's a whole lot of fire between your legs.
My man!
When you first started it was dragging the exhaust really bad which was causing lag on the pull that made it look like you had less power each time you made another run it freed it up more and caused it to show more power each time
All the shit talk on the z1 intakes, and you've got them installed upside down. The MAF sensors should be hidden under the pipes.
Dj: you got the exhaust on the roller
Jimmy: it’s all right
Ant: it’s good
Jimmy: oh wow that’s bad 😂
you know somethings up when DJ's the one who notices a problem
And still don't understand why the power numbers are going up each pull. lmao
YOOOO What if the exhaust rubbing was slowing it down and the more you guys ran it and grinded through the less it restricted the rollers and therefore resulted in the slow increase in power XD
Each pull wore the exhaust more causing less resistance on the dyno making your horsepower jump up each time!
It is so puzzling to me, that Jimmy didn't pick up on this immediately after seeing the exhaust lol
Get an ISR single exit and itll sound 10x better and more quiet!
With TP?
I ordered a z1 single, is that good?
JIMMY YOU HAVE THE INTAKES BACKWARDS THATs WHY THEY FIT WEIRD. Maf is supposed to be looking down! Like this so he can see
Dude I swear we tried both directions and they fit better this way 🙃🥲
@@JimmyOakes hmmm i have them in my G37 and they fit great not sure what happened with the Z 🥲🥲 that rubbing is going to be annoying
Good morning! Exciting stuff here Patreon gang.
This indeed is exciting stuff Nick
Always forget he’s got a Patreon just joined 🤓

you got the intake in the wrong side
Good morning Patreon gang 🙏 Stevie your dog is adorable 😍 RIP headphone users btw.
Ants reaction to all these numbers is killing me 😂😂 “OHH GAHH DAMITTT”
Flip the intake pipes, there mixed up boss
Get berk resonated test pipes,isr Y pipe and tomei or isr single exit for a nice no rasp setup 🔥💦
The exhaust probably grinded down a little more each pass and letting it make more power
Looks like you got the pipes backwards maybe. Might be why they're hitting everything
Power going up each time because he's clearancing the exhaust with each pull. 😂
The eye lids look dope the just need a respray. Then it will be killer
“Like if DJ should drift this thing”. Meh
Like if DJ should drift this thing with Lambo doors. 💪🏼💪🏼💪🏼
I don't understand this "out of stock" thing. I just went and did a search and found 4-5 intakes in a min. Cobb, Z1, Stillen, etc all in Stock.
call the companies and see what's ACTUALLY in stock.
@@drizzetsrevenge generally on the bigger brands/websites won't they say "out of stock" instead of add to cart if they aren't available?
@@TheRealMrRoyal larger resellers like Z1 have shipments coming in and out multiple times a day, and don't run live inventory because an item can go out of stock as quickly as it comes in, but will usually mark items that have an extended backprder.
I’ve always felt like the 350z HR’s “factory claimed” HP was a bit underrated.
Yo jimmy you can fix that strut bar rubbing against the intakes if you simply use strut bar spacers!!!
I mess with the eyelids, I can't lie. It's already lready a vibe, especially from a few good feet away. If they're painted to match though... I think they will look muchhhhh better closer up...🤷♀
Add some air ducts in the bumper to provide more air to the filters
@Rinda Foty reported 😊
You have the intakes installed backwards. with aftermarket intakes, the MAF sensor is supposed to be on the bottom. That should help with the clearance.
Jimmy, I know this is an old video, but the intake tubes are swapped left for right and upside down, MAFs go on the bottom.

Great to see Sammy back again. Them winter blues get me to..
Good call on the Z1 intakes. Definitely a good addition. Love seeing Z content.
as a gold LINK distributor, you should have something to say in other car models ECU's
It looks like you installed the Z1 intakes upside down. The MAF's are not supposed to be visible.
@jimmy could it be your getting parasitic loss from the exhaust dragging and now that the exhaust is getting warn down it has less drag
It was already tuned. Stock tune on a hr is around 275 wheel max. Plus the burble. It was definitely already messed with.
This dyno sucks for power figures. There always all over the place

your dyno def reads high. ported hr heads with big cams barely make 300wtq
How to Ruin a $1,000 dollar exhaust:
I feel like my Z lost a lot of low end when I installed the Z1 CAI. I am going to switch back to stock boxes w/ K&N drop-ins and the silicone post-MAF tubes. OEM+ish
That’s what I’m running rn, thinking of going z1 or stillen intakes.. is it really not worth it?
did the stock boxes feel better than the z1 cai?
Either the car is already tuned, or the dyno is still reading high, cause these cars dyno around 260ish bone stock.
All the cars on that dyno gives of way too much power. He should calibrate it, or fix it somehow...
Just roll around like dj with no bumper
If it has test pipes on it already without a CEL, it was more than likely tuned as they normally disable the post-cat O2 sensor in the tune.
VQ's normally will do better with stock airboxes than the short ram intakes, but there is typically another bump when you make the jump from air boxes to long tube intakes so it sort of makes sense. If temp in the shop dropped too that would help the numbers too in my mind.
Temperature of the shop.
So obvious but not once did it occur to me.
Temperature of the shop dropped enough in 5 runs to effect the numbers every time?
.. That is the silliest thing I've ever heard

I reckon not
Air temp will 100000% affect results on the dyno
@@PrimeMaverickAPB If it has a weather station though it will also be correcting results based on the lower temps. Not that it's perfect.
probably not because it's winter
Can confirm this channel deletes comments

I LOVE some hr vq action
Stevie is a great add to the channel! Keeps things fresh and those music videos are on point lol.
Those numbers are on par for an HR that's tuned,intake,exhaust.
I honestly wish Tommy crashes into Djs Z. I wanna see him drift his 370.
The dog licking the floor where he took a dump 😂
Z is looking mint now and a new shop dog? W's
I don't see many people answering Stevies question so I'm gonna say the little dog makes like 5 hp and about 15 lbs of torque!
2.5hp 20 torque
I think the intakes are backwards Jimbo, they look funny
You installed the intakes upside-down. The MAFs are supposed to point down
Swap them side to side
Seems like there's less resistance from the exhaust each time you do a run lol. Is it still dragging on the rollers towards the end?
More lenght and smaller diameter tube affect air velocity and usually generate more mid range torque. As long as the air is nice and cool should make more but if air gets hot propably makes less than on stock intakes
The power was low because it was scraping the exhaust hard and made more after it went through the exhaust
skinnier longer intakes make more torque
Intakes are on backwards
Ya need a flywheel my guy

From it rubbing on the bottom of the car. As it rubs more away it's making less pressure on the roller which make it seem like it's picking up power.

It’s like as you used the “self clearance” exhaust….as y’all threw those sparks could that have taken away friction on the roller and “added” power??
