built aba bottomend (2008cc)
20v head ported with all springs, retainers and ferrea valves, and QED purple cams
turbo: HX40 with BEP .70 ar ex housing
precision 46mm wastegate (18 lb spring)
CTS cast 4 into 1 t3 exhaust manifold
this thing creeps like a MOFO! it spikes to 25 lbs instantly then raises to 35psi before 7000rpm and there is no boost controller and i have changed the boost source from being in the manifold to right at the compressor. I want to eventually have the car tuned at 30 psi but right now if i keep my foot into it it doesnt ever seem to stop climbing in boost. I had a tial 38mm gate on it and it was creep so i said hey ill buy a new much larger gate and my problems will be solved! I was wrong... A couple things i didnt mention is its running on 94 octane, water meth and the engine endures the constant strain of a built 3 spd auto..
