Hey guys, decided to hit the rollers today even with some good old SC July heat/humidity. Overall pretty dang pleased. At 17psi on the street she was a beast and backed that up on the dyno with 820HP. Next was 19psi and netted 867HP. Lastly 21psi and 895HP/905TQ. Tried a hair more boost but she was breaking up and felt like the plugs was blowing out. We had a pretty hard boost spike at 5k, around 24-25psi when we tried to turn it up to 22 and that seemed to blow the plugs out every time. At 21psi, the spike was around 22-23. Then at 6.5k it was down to 21. I believe thats why my old dyno graph is so similar to this one as their is more boost early, then it drops up top giving it the flat curve and early HP peak.

Anyways heres the graph and vids. Next is I need some good weather and a 1/4 mile visit!

Its alive. I wanna see how fast and far you can go with this setup. BTW I like your dyno traction assist lol. Sounds mean like always.

 

Awesome man! Solid numbers and great TQ! Good luck when the track date comes!

 

Man, that 4.8 was screaming up top! go get some new times with the 5.7!

 

Man you are making me look silly, great job!

Were you spraying any?

 

Yeah the 4.8 could rap it out up top no question lol.

Atomic no one on here makes you look silly bud lol. And today, no spray man, just boostin her. Going to need a tighter gap or coils I believe for 23-24psi and then maybe a little cold air on top of that....

 

Big torque difference. Nice numbers man.

 

Nice numbers Foose. Do you plan on 24lbs being the highest you go?

 

Nice numbers. What hot side is on that turbo?

 

Thanks guys. Yeah I think 24-25 is most I want to push on stock 317 heads.
