Turbo Gurus....Need an Advice

2 posts in this topic

Well it came to its natural conclusion..... after installing pretty much all supporting mods as coilovers, brakes, sway bars and all other stuff......it was time to do it....finally: As of now: 450cc blue tops with resistor pack; small 16g with 7cm Bullseye hotside, Evo3 manifold and Evo3 O2 housing; DSM blow off valve; MAFT; silicone couplers with t-bolt clamps; MBC with quick bleed valve. HPIM0725.jpgHPIM0726.jpg Now the problem: I set the maft for about 50% down /lean it out/ as the car was w/o the turbo hooked up - it idles and it runs really good. When I hooked up the pipes, AFR went down to 10s IDK why, the RPMs would go up and down, it was a complete mess. I also noticed the the BOV is constantly open IDK why as well. Its vac line goes to the vac manifold, so is the boost gauge. It really makes me wonder. I might have over looked something, I will go over everything tomorrow. HPIM0728.jpg It was getting really late tonite and I was also tired, so I called the day, blocked off the vac line to the BOV, disconnected the IC pipe right after the intercooler and went home with a N/A car. I suck HPIM0727.jpg I most likely have some boost leaks, but Im really hoping that I dont. I can hear the turbo spool up, and I followed the instructions for the MBC. Its probably set to very low pressure. Should I bypass the MBC and hook up the wastegate straight to the J-pipe? Ive been working from about 12pm till about 11pm and it wouldnt be done if it wasnt my friend Skrap helping me. I ran into some issues, but It all went down pretty smooth. Id appreciate your answers about the opened BOV and the super rich AFRs.
