Hey Guys Im so confused as to whats going on with my car, When I get on it and drive to redline, I build boost strong until Im at about 5800-6000 then it kinda levels out like doesnt pull anymore, is that the sign of a boost leak, Im only hitting about 5.5lbs actually just below and the needle shakes like crazy when it gets up there at about 5ish. I do have test pipes and HKS exhaust so Im not sure it that would drop the Boost,
Oh and its the stock pulley For now until I get this fixed.

 

tighten your belt

 

I tightened the cog you think it could be the drive belt?

 

under normal conditions, cog belts dont slip unless theyre super loose..........if a cog slips then youve got bigger issues then a boost leak.

The belt that would be slipping is the main drive belt around the jackshaft pulley. Are you running a 3.33?

 

yeah I have a 3.33 it feels like its slipping, but it feels tight to the touch

 

if its not that any other suggestions Im gonna put it up in the air tomorrow

 

LIke everyone has stated tighten the front serp belt. To u it might be tight but it wont hurt to tighten it a little more to see if u can see more boost at redline.

 

yes

 

Its most likely belt slip. I thought this vid was a boost leak but the whistling sound is my belt slipping not a boost leak. Check out some of my other vids for different belt slip sounds and issues. http://www.youtube.com/watch?v=VC9Q_xk4mrE

 

thanks for the vid that's exactly what it sounds like from driver side too
