    Yeah thats what I was thinking. I cant believe how rich it was running. It was ok for a few minutes and then just started bucking. I pulled a plug when i got home and it was dripping. I was nust happy to hear the turbo spool.

    Ok, I need some help with what jet sizes I should be looking at for the primaries. 74 jets in there now and the plugs are really fouling. Thanks.

    It should start spooling when you get it leaned up. If the plugs are dripping, that alone will hold up the turbo as the exhaust is super rich.

    Thanks Sean, I know that thread is a must read once or twice or ten times. What I found out today was that the pipe clamps I had joining the two sections of pipe leading to the turbo just didn't want to keep them together so I think the turbo ended up acting like a choke when the pressure was escaping and not turning the turbo. Took the clamp out and welded it.Thanks Ray, it is spooling now, seeing 6 lbs of boost but not right away, still a lot of tuning to be done. I love the sound of it spooling and then the blow off valve!!! It isn't even that loud with no down pipe or muffler. Still need to make a down pipe and install the wideband, it is definitely still too rich off idle. Also, I had my first scrape of the exhaust pipe tonight, It was a pretty nasty dip though, the rest of the ride was good. The next version will be tucked a little closer to the frame. The car is lowered an inch too. Thanks guys.
