1 slow Audi

I ran the car at 21 psi this weekend and it is pretty fast. I raced a 1989 trans am pace car wich came with the grand nash motor 3.8 turbo he ran a 12.5 at Cayuga race park. He has few mild mods; cam,20psi looked like a stock turbo,intercooler piping,blowoff velve,
Bf goodrich drag radial,and race gas thats all that I saw and what he told me, annyway it was a dead even race we went twice and both times we were even all the way to the end but on highway he will pull on me. Im leaning out top of 3rd 4th and 5th the 550cc injectors are maxed out 100% dudy cycle. I bumped up the timing to 26 degrees advanced at 20psi and the car started starving for gas so I didnt ran the car at 30 psi yet. With the timing retarded at 21 degree the car was doin fine but when I started advancing it every degree advanced the fuel map was getting higher and higher and the 550ccs arn't just cuting it so Im ordering 1000cc injectors. Annyway here are the pictures.

Looks promising. I like the placement of the wastegate and the cone intake just in front of the turbo. I can't see the throttle body very well, or how the runners meet the plenum internally, but based on the rest of it I am sure you did your homework. Dump valve should sound cool, one of the benefits of a speed density system.

Doubt it will idle on 1000cc injectors.
