Hell yeah, Josh! Thanks for the update... this looks very promising.

sweeeeeeeeeet

oh wow... amazing, just amazing... TQ could be higher, but the power with an auto G37 with big heavy wheels, its expected. I'm predicting a 450whp 370.

Red370 · 03-03-2010, 07:53 PM

Oh, and the fact that those are CARB legal numbers... Stage 3? 500whp?

Zsteve · 03-03-2010, 07:59 PM

price? hmmm both kits very close in numbers but one has a little more TQ, price is going to be the factor I think.

I'm wondering if this dyno used the big wheels because if so, it would close that TQ gap. Thats why I mentioned that earlier. If not then maybe once this makes it to the Z 6MT it'll pick up some gains.

good point, why the heavy wheels to begin with? Is the carb legal at 8 psi?

Different dyno's.. Different dyno operators. Comparing them and trying to figure out why one has 10 more torque is pointless.

You think so?

From what I can see and what I've read previously in this thread...

1) Add 5% for heavy wheels.
2) Add 7% for Automatic transmission
3) Probably running less PSI than race kit. (6ish most likely)
4) Less aggressive tune.
5) There are obviously restrictions in the exhaust system to keep it CARB legal.
6) Im not 100% on this, but I think that G had stock intakes for baseline.

Anyone care to do the math for the race kit on 8 pounds?

8 psi would be considered race and not for carb legal? cant wait to see the final results from both kits and pricing. I still think pricing might be the deciding factor, atleast for me it could be.

I wouldn't consider 8 PSI a race kit. I'm thinking 10 PSI.

cotizi · 03-03-2010, 08:12 PM

Why a 3rd gear pull? What's the gear ratio on a g37? Also worth noting is that the baseline is a stock g37, versus the supercharger that includes stillen exhaust. What psi was this run done at?

Quite nice for a CARB kit, for sure.

Red370 · 03-03-2010, 08:13 PM

The car will make more power on the 6MT 370, so dont use the G as a reference point. Also keep in mind that this is their CARB kit, numbers are low to keep it smog compliant. The non CARB, I/E Stage 1/2/3 will have significant increases in power because smog will not be taken into consideration and there will be more aggressive tunes.

LiquidZ · 03-03-2010, 08:38 PM

Ah yes, this is looking mighty good Stillen. I'm very impressed.

LUVZTTZ · 03-03-2010, 08:43 PM

Where did the 8 psi come from, or is that your guess?
