I will list but don't have any rwhp numbers. Is that ok?

322WHP no tune, 7AT, and that was while hitting the speed limiter

EDIT:

As for my mods:
Stillen G3 with K&N branded water sock things
Megan Test pipes (had a CEL)
Stillen exhaust
Stillen UD pulley

NO tune, stock sport wheels with 20mm Ichiba bolt on spacers, Yokohama S.Drive tires


I only have my 4th gear pulls on a DynoJet at 321, and 4th shows less WHP
When I get home I'll try to find the runs

310/241lbft STD Dynojet (busted, flip flopped, and miswired O2 sensors)
290/223lbft Mustang Dyno (busted, flip flopped and miswired O2 sensors)
AEM CAI
PPE LTH
Motordyne Y pipe and HFC
Tanabe Medallion exhaust
NST pulleys
Tune (don't ask me how with busted O2 sensors)

Thinking I left a good 20whp/tq on the table :|

Z1 test pipes
Tuned at Uprev in Austin Tx

324whp/257wtq on Dynojet
Est weight of my Z- 2970lbs

Had exhaust leaks from both TP to header flange (thanks Uprev!) Not sure how much HP that was causing me to lose, and I've also went with a Litespeed CBE. Plan to re dyno when I get a chance.

342/275
Stillen Gen 3
Z1 intake manifold mod
Momentum headers
test pipes
Invidia Exhaust with muffler section removed and replaced with 12" glasspacks
Z1 tune.

Pretty sure these N/A numbers shut everyone down. I'm headed to Z1 soon for my tune and i'd be happy to get close to these.

If you aren't above 320, I probably wouldn't post on this thread haha!

The rest of us cant hang yet- Great job though guys!

Mike, awesome numbers!

its why I don't really want to post mine !

Dyno are only a tuning tool , one read low the other read high ,, so its kind of useless

copy/paste from my signature ! Ver.1 once started at 256whp then died at 324whp.SAE 265 TQ
which is a gain of 68whp.

and for you guys on the Dynojet showing std # ,, well I got 330

mod list;
custom CAI/Maf tube
overzied TB (proved 7-9whp gain)
custom 350z HR intake manifold
PPE header
Custom X-pipe / muffler setup to reduce Decibel at the track (restriction means lower higher power.)
NST pulley kit
7AT (usualy read lower vs 6mt)

I wish I didn't blow that engine ! lol there is quite more to be gained.

2009 7AT

fast intentions nonres TP
fast intentions nonres CBE
Akuma long tube prototype intakes
AAM tuned

324RWHP/258RWTQ

yea i made that with only exhaust, intake, and a tune. no headers, no MAF mods, no TB mod, not intake manifold or spacer. :tup:

dyno video

I only posted mine because I think it's a miracle the car made what it did with O2 sensors that didn't work. Think about that for a moment. FYI, Car put down 309 SAE as well before a tune. Hence why I think there was a lot left on the table had the car been working 100%

Mine was on a generous (Dyno Pac) dyno :ugh2:
1/14/11

Mods:
FI exhaust
Stillen Gen3
NST Pulley kit
UpRev tune
Trans 7AT

good job. :tup:

what was your baseline on that same dyno with very similar weather ?

isnt dynapack one of the higher reading dynos? not trying to :stirthepot: just interested since i cant remember exactly which ones read highest and lowest.

oh, I could say that im also in the 340+whp SAE # with this, right ?

if I didn't specify about the 4th gear ,, I could claim that 340+whp SAE.

http://www.the370z.com/members/megan...ure43795-a.jpg


well it depend,, during my dyno test day , I got 321whp SAE on the dynojet and 324whpSAE on the dynapack I use to go for tuning. this was the same day , within 2 hours from each other,,
so its really depend how the dyno was setup

they baselined it prior to tune and it was 309RWHP/250RWTQ

i never had it one the dyno prior to my tune.

Nice Numbers Fpenvy, I'm going with that same setup aswell besides the intake system I have k&n short rams though lol

nice! my only goal getting tuned was to hit 320rwhp. i was extremely surprised and pleased when i saw 324.

True, but the Z1 dyno has seen many 370z's, so its also a good comparison tool. I don't remember what my baseline was honestly though, it was so long ago. However, since then, I believe Russell's car (owner of Z1) made came within 1 hp of mine but with slightly higher torque. I know before the headers I was 311 on their dyno.

Mike, go back and dyno with a few gallons of 100 octane and then come back and tell us your numbers :)

What is the Z1 intake manifold mod?

mike are yours SAE (inflated) numbers?

i've gone through countless build threads and dyno threads but your numbers just seem "too" high. i've seen multiple people with many different brands of headers who are a lot lower HP than what you have listed.

i'm not trying to sound like i'm calling you a liar. i'm just curious as to how with very similar mods plus headers you are 20HP or so higher than me.

his 342 is STD number which are higher than SAE.

I will let Mike speak about about this but I will still add my small opinion on this.
that number of 342whp STD is plausible and when he shared his number with us, I did a research with others known high number on the forum (similar mods).

its all depend what component you have and the tuner.
I know when he got his 342.. Z1 had access to the Uprev beta for the VVEL adjustability , they did said they played with this . but gain were very limited.

also remember his Z is 6MT instead of 7At like yours, should have a few whp different right there.

the trick is to not have a too big exhaust like double 70mm as example from what I gathered.
Mike was smaller if I remember correctly.

I have momentum headers and my car was tuned at thee Uprev in Austin Tx, the actual headquarters and my car only made 324whp. I'm not sure if they messed with VVEL... Maybe Mike's Z has other secret mods he isn't mentioning lol

i've looked and havent found many Z's over 330whp besides that fake 403whp one. (some 330WHP were on dyno with tweaks to make numbers bigger i believe) anyone can change variables and have higher numbers not saying this with mike's. just saying i know it can be done easily lol

my exhaust is 2.5" which is only 63.5mm

7AT does have around 15-20% more loss of power through the gear box from what i've read. i mean if you add those in i'd be much higher than him or anyone so i find it hard to believe it's that high of a difference given my mods.i'm guessing it's more like 10% difference.

soooo they used software only a few shops have access to. lucky bastards lol

i just want to see how headers/secret z1 intake mod/and beta software jumped him 18whp more than me. possible point me in the direction of future mods to beat those numbers lol

i may have to think so lol :stirthepot: :bowrofl:

difference from 6MT to 7MT is less than 5%.
There was a guy here who were doing that research which I forgot his name. My guess was 3% more drivetrain loss on the 7AT Vs the 6MT.

as far as the VVEL tuning , they did said they couldn't do much with it. need more time learning to tune it properly I suppose.

Mike had this exhaust that was modified with glasspack muffler
60mm exhaust . Invidia Gemini
http://www.jscspeed.com/images/catal...thumb_full.jpg
Spoon did like 32Xwhp with a very similar setup but with 2x 70mm exhaust. Its where I think he lost power because of that.


then again Dyno are a tuning tool ,, unless you go for some pull on that same dyno where Mike's Z went, with the same seting and everything, we cant know for sure if you are or he is making the most power.

yea i know it's not a big percent hence why i said i didnt believe when i read somewhere saying it was 15%

based on the VVEL tuning not being really useful yet that still makes me wonder what they did to pull 342whp.

i doubt glasspacks help with HP pretty sure thats a sound mod lol

326whp - 268tq

We don't think the glasspacks help, but the 60mm tubing probably does. As for the intake mod, I don't really know what it is, that is Z1s secret. Their shop car is making the same power as mine also.

I do think another possible difference is that I didn't baby mine during break in and its been 90% hard track miles since day 1.

Other possible factors are maybe my quaife lsd has less drag than a stock one, but I have no idea on that one, and also maybe because my race wheels and tires at the time were a good bit lighter and smaller diameter than street wheels and tires could also help. I think when I actually had a set of street tires, the car dyno'd 6hp lower

Hmmm all interesting. Just trying to see where there is a 20hp jump is all. Curiosity for future mods is why I'm questioning it. Hope none is taken in the wrong way.

LSD may have some factor in it but I'm with you in being unsure on that as well.

I'm just running the stock sport wheels and pilot super sport tires obviously not as light. Not sure if that would make any significant difference or not.

No biggie, because personally, I don't really care. All I care about is being faster than the much more expensive cars at the track :)

327 whp / 255 tq in 4th gear (local tuner uses 4th to avoid additional stress during tuning) on an AWD Mustang Dyno.

Anyone know how 4th gear pulls compare to 5th gear pulls?

depend on the dyno .

on a dynapack I get like 34x whp on the 4th gear but 324 on the 5th
on a dynojet I was getting a lower reading with the 4th vs the 5th gear.

http://www.the370z.com/members/megan...ure43795-a.jpg

So Mike, when you went from 311 to 342 was it only the header change or did that include the mystery intake mani as well?

I'm not entirely sure, but I think it was at the same time. I sometimes keep my car at Z1 over the winter when I'm not doing track events though, so I'm not sure exactly, but I think it was with the headers.

Georgia has a winter? :roflpuke2: Come to Ohio and experience a real winter. :ugh2:

Cool thanks! Now I'm curious about this mani I don't think I've read about it before...

ohio? come to PA and try that out lol

I think I like the 1/4 mile thread better :\ dyno inconsistencies make this thread very misleading

If anything, people should be posting their before and after, the differences between a baseline to mods+tune or whatever you may have, however I know a lot of you guys don't have baselines so that rules that one out
