I was at the track the other weekend, and between shifts (3rd to 4th) something happened ( I thought it just threrw a hose) and the car went from driving perfectly to having zero boost in any gear. The car did not smoke or anything, just lost all boost. It actually drove fine on a cooldown lap, it just had no boost. It starts, runs, idles, and shifts fine it just won't generate ANY boost. I have inspected all the usual culprits, ie. hoses, clamps, lines etc and can't figure it out... any ideas???

If you have a seized or jambed wastegate you can lose all your boost.. Check your Bypass valves..

I think that's the issue, It there a way to un-jam or is it time for new ones. What do you reccomend for new ones??

I can rebuild them.. It's like a valve guide.. Drill them out and replace them.
