N/A HP BRAG thread

[NickTurnon]

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.

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

good job.

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

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

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

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 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

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

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.

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%
