Glad to hear good things about the kit again, go figure custom tunes and perfection. I do find it funny(watch the fan boys come out now), that someone installed the GTM, and now their is a fluttering noise that they havent figured out. I guess the all perfect gtm, isnt as perfect as it seems.

I am sure with time itll get fixed though, just like the stillen issues are.

Twin Stillen Supercharger

TKF racing Stillen Supercharger

Insanely nice looking ride ^ PW

Omfg hot! ^

Not sure if it was the same article, but I read 0-60 in 4.5 secs, and that's 0.7 secs quicker than the stock 370z previously tested by the magazine. 12.8 @ 113 for the quarter mile.

I don't think stillen had tuning problems w/ their press car, just certain ECUs.

The test car had KW V3 coils, Stillen rear sways, AP racing brakes (6 front 4 rear pistons), and enkei gtc01 19s w/ 10mm wider than stock (255 and 285?) toyo r888 tires.

The article did mention that they "predict better numbers are possible with less camber than what came dialed into the rear of [their] test car".

The one I read is Road and Track, 12/2010 issue.

THat 350 needed 2 power adders to hit 444whp?

Dyno Results
 

4th Gear: 352.4 Rear Wheel HP, Torque 293.2
5th Gear: 375.7 Rear Wheel HP, Torque 300.8

I was told to get Engine HP divide by .8

4th: 440 HP
5th: 470 HP

Did three runs and the best of the 4th gear run we kept
Each time we got to 160 mph, 7500 rpm got the electric cutoff, it was starting to flatline anyway. The Fuel and Air looks good all the way through.
It was 61 degrees outside. Oil temp never got above 250F
I asked how the Dyno itself was calibrated and the Tech told me it was all done through the software. I asked how often the big wheel is greased up and he said every 6 months or by hours whichever comes first.
Running Super Unleaded, Stock pipes, no oil cooler, just skin and bones.
Hopes this helps anyone else.

That might work randomly for random engines, but it's not going to be consistent nor does it work mathematically.

HP = [Torque * RPM (at given torque value)]/5250

Yes. It looks to me you are right. This one is for Rotational Horsepower.

Lowers my Engine HP numbers by about 40 on each (if peak is 6700 - 6900 rpm).
Some could consider Horsepower is actually obtained in a quarter mile run matched with the weight of a car and how fast it is going when it hits the trap in real world conditions.

HP = weight x (velocity/234)cubed. The Dyno is Static.

Thanks for the post on that. I don't know where the Tech guy got the .8
I bought it though.

The Tech guy probably didn't have to take a lot of physics for his engineering degree ;)

Edit: I use that equation you posted for my hp/weight based trap speed calculators...incredibly accurate, neat math trick used in it to factor in drag. I was able to confirm this when it actually calculated the top speed of the Bugatti Veyron SS within about 1mph based on the stock ones stats (since drag & frontal area would be very close).

That formula the tech gave you was to obtain a rough estimate for your BHP since you already have WHP.

Well done car. I like the PW Amuse, Gunmetal BBS combo.

He wAs probably assuming 20% drivetrain losses.

^ Exactly, thats a little high for a RWD system though. More like 15% normally (on dynojets). By his math I make like 570bhp hahaha, so far from the truth.
