Hey guys... wanting to see if any of you have dyno'd your car after the following mods. I'm wondering what hp numbers the ole' G coupe is capable of after doing all of the following:

1. Stillen CAI
2. Borla true dual exhaust (no header)
3. Angled plenum spacer
4. Lightened crank shaft pulley

Anybody?

 

look on youtube theres mad videos of G's on dynos

 

dont forget testpipes or high flow cats!

 

Maybe 250 at the wheels !!!

 

^+1 i'm gonna go with 250-260 TOPS

 

your only going to see noticable power from the spacer...

Borla is crap!!!

 

that sux. I've listened to tons of sounds clips. I love the stock exhaust most but the borla system is the only one that doesn't make it sound like some ricey honda. The G is just way too classy to make really really loud imho.

 

with all of that, almost exactly what I have too. Youll make about 10-15 whp max.

 

listen and do some research on the Fast Intentions Intimidator exhaust and Stillen TD... they sound close to stock just deeper and louder...

also i would look into the motordyne 5/16 or 1/2 spacer...
