Edited a couple things. The boost seems low to me for how hard I'm spinning the blower.

 

[98 Saleen Cobra]

I wouldn't worry about the boost.. That motor is extremely effiecient... It wouldn't suprise me of you're loosing 4-5psi through that motor over a typical setup.

this... that motor is taking in alot of air

 

[01yellercobra]

I did some quick math and using the rough estimate of 100% VE my engine is using about 1000cfm of air around 6k. The T trim is listed at maxing out at 1200cfm.

I do know the car is no slouch. Now that I have DR's I can add some timing.

Was hoping for a lot better numbers than this but I'm thinking the CX core is my hold back at this point. Plus had some spark blow out around 6k+ rpms.

Your setup is very similar to mine. I'm having tuning issues right now but am hoping to hit what you have. Can I ask how big the inlet pipe to your throttle body is?

The first motor with a P1 that I have ever seen report a dyno number that high. Congrats!

Inlet to throttle body

It's the stock plastic for the bullit intake and I had to rivet it to the hoses to keep from blowing off!:rockon: I think it's BBK that makes an aluminum one I just haven't bought. Oh and get a power pipe you'll need it!!

Thanks I was shooting for 600hp like project icebox!! Just missed....:shrug:
I think I'm gonna drop from 3.4 inch pulley to a 3.1 and add meth to get me over the hump!! Or leave it and ad a 50 shot... I think the 50 shot is a lil Risk-A for me though....lol

Cool, trying to figure my issue. It cuts fuel at a specific cfm. It's weird, hit 500whp on a 13lbs pulley but it would barley drive with the 17lb pulley. Thinking the 3 in pipe is too small.

 

[SVTPete83]

Here are the new numbers with the T Trim. I didnt quite make the 600 I was looking for but was stoked that we gained over 50 HP while dialing the timing back 6 degrees at the same time. My race gas tune will be a beast. For now I am pretty stoked!

Nice gains there Pete! Bet it sure is a kick in the pants when the boost starts to ramp up.
