I’m running AMS 780cc with my 3071 and they are at 80-85% duty at 27-28psi.

 

well... the 71 doesn't really flow as many pounds at 27-28psi...

 

Even on my race gas map running 30psi. My A/F are in the 11's on race gas and in the 10's on pump. I am using the stock ECU which allows more injector overlap then w/ a standalone.

 

hmmm dunno why mark moved to 1000cc then...

 

How much boost can you push on 680cc with the 3037 and what intake do you guys use also

Thanks

 

I run 30psi w/ the 680cc using the stock ECU. I use the stock intake box too w/ stock filter.

 

What fuel are you using and how are your #s also for power.

 

I run 100oct for those 30psi runs. I made about 70whp more then cars w/ cams on pump and I only made 70whp more then cars w/ cams on 100oct at only 26 psi. At the time, I could only reach 26 psi due to having the wrong wastegate spring. At 30psi, I probably make 100whp more then cars w/cams on 100oct.

 

JJ008 your trapspeeds say otherwise in regards to your power level. I feel running 30 psi is hurting your power but I could be wrong. But I am positive your car is not making the big power u think it is or the big power it should be making. Your low stocktubo like trapspeeds support my hypothesis. I hope u figure it out.U seem like a cool guy and I wish u the best.

 

Its the stock I/C on a 90 degree day that is hurting me. On the dyno, when it is 65 degress w/ 3 huge fans, I threw down some good numbers. Unfortunately, when it gets over 80 degrees my car feels like a slug. So at the track on a hot day, my turbo is probably turning 35psi just to make 30psi in the intake. Which means it is blowing even more hot air since the turbo is out of its effiency range. Plus, sitting in a staging lane idling doesn't help either.

Soon everything is going to change. .

 

Good luck. Get that thing dialed in and lets go to Vegas and shut down Evo81 and his Posse.

 

 

Just put in a 3037 kit with 750 injectors. I'll find out what kind of number its doing this weekend when its dyno tuned.

 

I am worried about using this caliber of a turbo with a stock manifold. Should I port it? Should get get that Megan Racing twin scroll one for only $299 or so? That may actually be the answer and just port the 02.

 

nothing wrong with the stock mani... it's not the best flowing ever. just get a cheap mani... any one of those hks knockoffs with a warantee.
