Sweeet! What is the O2 hsg?

Why the new injectors? What is your duty cycle?

 

those are nice numbers! I was just there this past week. I had GSC 272s installed, but i only made 320whp and 301tq. My mods are 272s, fuel pump, maxford manifold, 3"tbe, mbc, k&n cone filter. Mark said i may have a tank of bad gas. But for some reason my car is stalling with the cams. I may need to go back again for a retune.

 

yea im worried about my clutch doing the same thing when i modify, and i cant afford an exedy twin, and have heard too many bad stories about the ACT. Good luck with ur situation though.

 

Nice Numbers.......

 

i have basically the same mods plus a few things, Mark is coming next month for a dyno day tuning, i hope i get some good #'s

 

100oct and 21 psi is pointless. 100oct and 24-25psi has reasoning.

 

I agree. More boost and your car may come very close to 400WHP especially since it still had more in it before the clutch went. Very nice numbers, hope you get your clutch issue worked out.

 

Boost isn't the only way to make power with higher octane. Timing advance makes a huge difference and you can push the envelope on higher octane without running a bunch more boost. And with only 100 octane, you can't really push the boost and timing too far. Big difference in knock resistance between 100 octane and leaded race gas.

 

If you read my post... the clutch went on the dyno. 26 psi will happen with the new
clutch.....

 

Uh yeah, flash high timing numbers so on 93 octane he knocks and blows the motor on 21psi. Boost and stock timing numbers is the way to go for horsepower that can be used at 21psi on 93 and 26 on 100-110.

 

What clutch are you going to use?

 

Act, And yes I heard about all of the problems, And I think they are driver errror.
Mark and Jeff used the act in the race car for almost 2 years and had no problem.
They had to upgrade because of more power.
Dont forget to look for the new Dyno sheets on Thursday.

 

Wow i can't wait to get my cams in my car!!

 

I did the GSC cams, they are great speek to Gregg. He is the man...
