[QUOTE="lucheski, post: 15400084, member: 45286"] Cars been running for a little while now, I have just been busy sorting out issues, the tuner has had trouble getting it to idle, turns out the IAC motor was bad...I found and fixed the bad IAC this weekend also gapped the plugs down to 0.025" going back to the dyno tomorrow. It was also breaking up past 4000rpm on the dyno we think it could be spark blowout or possibly a bad coil. With the 3.5" pulley it made 20.7psi vs 17-18psi it with same pulley setup on stock motor. So I picked up about 3psi boost with same pulleies even with the big cams.. the porting and TB definitely made a difference. Once i get the car sorted out on "low boost" I will be throwing the 3" pulley on there which will effectively spin the 2.8 Blower to it's max rated 18,000rpm @ 6700 engine rpm [/QUOTE]
