Actually it says right on the bottom of the dyno graph it was running at 0.4 kg/cm2.
(0.4 kg/cm2)x(14.22334) = 5.689337 psi

Well kg/cm^2 is just another label for bar. And 1 bar = 14.5 psi

Therefore (0.4 kg/cm^2 x 14.5) that's almost 5.8 psi if you want to be accurate

Yeah, I did the same thing, but with the 0.45 kg/cm2 that was quoted from GReddy's blog post. Someone at GReddy made a typo either on the dyno or in the blog post:

"On SP's dyno the base Tuner Kit with the optional pre-programed emanage Ultimate fuel kit and full dual 70mm Turbo Ti-C exhaust the Z put down a healthy 449.5whp! at just 0.45kg/cm2, on a conservative 91 pump gas tune."

Welcome to the official GReddy USA blog: 450whp Tuner Turbo Kit for 370Z coming soon!

Sam you are a cool guy but conversions is kinda what I do for a living.
1 bar = 1.019716 kg/cm2
1 bar = 14.5037738 psi
so
1 kg/cm2 = 14.2233463 psi (If you really want to be accurate)

But you are right that 14.5 is a good approximation



I did not see in Greddys blog post that they said .45 kg/cm2. So that would be 6.4 psi.
Either way it is impressive.

FAIL. Everyone knows that you ALWAYS carry numbers to at least 10 sig figs. Sheesh!

I just wanted a turbo to make it go "Vroooom!!!" I had no idea long division would be involved. Since I've read this thread, my head hurts. I'm going to take a nap.

some people just didn't like the Greddy E-manage system for tuning. I'm waiting for some specs on the JWT kit. It's been tough for these companies to come out w/ aftermarket pieces that will work in this economy

They should post their torque numbers in Newton-Meter to be consistant.
