Great post, I was just curious about the dyno numbers. If I'm not mistaken, the new VQ37's are cranking at 332hp. And you got numbers at 256 to the wheels. That's nearly 23% drivetrain loss [22.89 to be exact]... Don't RWD's loose 15-20%? 20% at most to the wheels? Also your loosing 24.4% for torque @ 204. This link under "more info" provides other links to other 370z's dyno numbers and videos.

YouTube - Nissan 370Z Z34 on Dyno 12.10.08

But after calculating correctly these are the numbers I got:

332hp/270tq @ crank

STILLEN: 276 RWHP and 227 WTQ
-0.16867469879518072289156626506024 HP
-0.15925925925925925925925925925926 TQ

GT Motorsports: 287 RWHP and 237 WTQ
-0.13554216867469879518072289156627 HP
-0.12222222222222222222222222222222 TQ

DD Motorsports: 285.46 RWHP and 243.40 WTQ
-0.14018072289156626506024096385542 HP
-0.098518518518518518518518518518519 TQ

Injected Performance: 258 HP
-0.22289156626506024096385542168675 HP
TQ unknown

370z dyno: 289 rwhp and 229 rwtq
-0.12951807228915662650602409638554 HP
-0.15185185185185185185185185185185 TQ

16% was the average RWHP loss for these five cars on their dyno's
13.25% was the average TORQUE loss among FOUR of five cars, for Injected did not provide one.

It seems that you and Injected both lost about the same percentage of HP. Figures for torque I can't say, but wouldn't be surprised if you both received the same torque too.

I'm just curious, and if you don't mind help a congested brain like mine understand better, I'd really appreciate it. =]

BTW, beautiful car!!!!

First of all thanks!

Secondly, to answer your very well structured post (thank you for actually making a case and trying to get somewhere. It is a breath of fresh air!) The discrepancies here are only a matter of what dyno was used to do the testing.

Injected and I both tested on a Mustang Dyno. This brand of dyno (not at all related to the Ford Mustang) usually reads about 8-12% lower than most others, such as a dynojet for example.

I really appreciate what you have done with your data and would be happy if you would post that information on another thread I made where I wanted to compare dynos.

nice post bro...

RCZ,

I don't want to assume anything (btw, awesome feedback on the Z so far!) but the hp numbers you have as your goal in your sig, is that NA of FI? If it is NA, what mods are you planning to do to get there? Keep it up!!

S.

o0javi0o · 03-20-2009, 08:42 PM

Awesome!
Would love to see soon a clip of the new sound that your Z is going to be making after the installation. Also which is going to be the increment in HP of the baby

RCZ, great great Review, just great.

N/A

Intakes/Headers/Test Pipes/Catback/DynoTune/flywheel/oil cooler/luck/ prayers. I think it is possible to pick up 50whp with these mods.

Whats up Javi! Oh man I completely forgot about Ultra tickets!
When are you coming back down to Miami?

Thanks

I had a hook up from a friend who owns an exotics dealership. Its some special tint that he called 35% that is usually used when customers request dark tinting from Porsche factory. He said it is somewhere between 25% and 35% in the real world. The cool part is that is that it is surprisingly light from the inside. You can tell sometimes from the outside when the light hits it, but anytime before 11AM and after 3PM, it looks really nice and dark from outside.

To make the answer short. 30% Ill try to get a picture from the inside sometime.
