Not sure, may need a second opinion??? Right now I have the Fidenza FW, ACT Clutch kit and street disc installed... A few days ago while driving I've noticed the car hesitating under-boost... It was like a jittering affect. Under-Vacuum everything seems in order... I also noticed this problem while going up hill under load and this jittering affect happens.. At first I thought it was a fuel issue, but the fuel pressure is normal.. My EGT shows 1000F-1100F while cruising at around 70mph-80mph.. To my estimate, the egt temp is good..

Currently I'm running 4psi.. If I'm driving say in 4th, doing 70mph, while in vacuum I have no problems... But, as soon as the boost needle approaches 0 this jitter will start... It is most noticeable if I punch-it while in 4th or 5th gear.

Under-boost my egt reads 1200F-1300F, so I guess this is acceptable... And finally what I guess is the "Smoking Gun" I started to smell a stink order from under the hood... So my suspicions points to the clutch...


I had the clutch for 1 year. I thought the ACT kits can handle boosted power???

 

I boosted 10.5 PSI w/my turbo and I have the same thing you have and it has not slipped I put down over 300HP/tq.

 

Ok.. I see... A friend of mine is telling me it may be a Vacuum leak... He says under-boost this can happen... It will cause a surging effect.. Looks like I need to start checking all my pipings and hoses...

 

whats up jay,
im just curious, how is your throwout bearing holding up. i had a 96 five speed with about 300hp and had to replace them a lot.. as you know im currently running autottragic because of that reason.. is it stock or
something different. if so whats the most hp you can put to them..

 

whats up morf,
did you fix the car yet.. when you left it sounded strong.. i cant wait till you get it right so i can see you kick some butt.. i think a lot of people are gonna worry now.. good work though.. mine is almost ready installing purple dash lights to go with the purple H.I.D.. hope it looks ok
probably will be out wed. at least i,ll be close.

peace

 

No... It seems I may have a bigger problem. Under boosted conditions the car hesitates... I've spent all day monday checking for vacuum leaks and nothing.. I unplugged the MAF, the car started, but stalled if you move off.. I treid using quick-start to test for any surging and nothing.. At first I though it was the clutch, but its fine... My fuel is fine... The next thing is to pull down the turbo to see if there's damage?? Keep you posted.
