Well my car has had problems with stop and go situations in the heat if you haven't known. it doesn't like to go into boost and all it does when i get to a certain point like 2500rpms it will just rev up and barely accelerate with no boost. This is only when i drive it for a while not off the start.
Now, that its getting cooler i thought my problem would be gone. Now I drove and it drove wonderful, then i let it idle for about 5 mins and then tried to boost it and it wouldn't do it. it started acting up only between 2500-3000 rpms. it will rev up all the way to redline but with little acceleration and no boost. It feels like the clutch is slippingEven tough it is not as worse as it is when its hot it still does it.
After trying it out it will go into boost, and then if i let it idle and tried to boost it won't ill stop and let it idle again and the car will work fine if i dont step on it, but it does go into boost. also when i had the problem i went on the freeway to test it out. it will do it in the low gears but catch in 4 and 5. and then after driving at a stready pace for 5 mins. it can go up to ful boost again. WTF?????
reposting my problem? is it my brand new stage 3 clutch?
What kind of boost controller?
I'd test it by sticking the line from your hot pipe that goes into the boost controller directly to the wastegate bypassing the boost controller entirely, that should enable you to run 7psi max. If it still don't boost, take off the line completely to the wastegate but watch your boost, if it still has no boost, you either got a wastegate problem, there's exhuast leak before the turbo, or leak in your hot pipe (which I doubt). Check those out.
If bypassing the boost controller works, it's the boost controller, I assume it's a electronic boost controller.

I have a mbc but im not running it right now. im running 7psi perfectly fine. The car has been running for about half a year with no more than 4000 miles on the motor, the turbo had no shaft play. I tested the car out today. i rode down the freeway with no problem. stop and go a little but not much. once i was headed back home i stopped and let it idle in a parking lot for 3 minutes, tried to go and wouldn't accelerate. once i had it going it would not catch aclleration between 2000-3000 rpms. It felt like a had my foot on the clutchThen i let off the gas peda after reving real highl and after trying to acclerate, after 3000 rpms it will go back into boost and work fine. coming out of first gear when i got home felt like i had my foot on the clutch and it was completley off!wtf!

Re: (toledo240)
Have you tried adjusting your clutch pedal? Sounds like it is on the virge of being engaged and when you give it some gas it is slipping. You didn't get any kind of lubricant on the clutch surface when you swapped it did you? Definitely sounds like a clutch if it revs up but goes no where.toledo240 wrote:I have a mbc but im not running it right now. im running 7psi perfectly fine.

try adjusting the clutch pedal first. Make sure that when the pedal is all the way out the clutch is fullly engaged to the flywheel. Did you replace the throw-out bearing when you replaced the clutch?
Also, if the clutch is slipping at 2500 rpm then that can explain the lack of boost. there will be no load on the engine if the clutch is slipping and that means you will have no boost.
throw out bearing is the original never replaced. I haven't tried to adjust the pedal, but i have had my foot all the way down on the clutch in 1st gear and it didn't move, am i testing it right.(to see if my clutch needs alignment). Also when people that never drove my car before will make the clutch make a squeel nose from the clutch. kind of sounds like a mini burnout, also when i drop it into a lower gear hard it will squeel at me!Now when i am into that boost and accellerating problem the clutch will squeel without even switching gears, but when i try to accelerate. once again wtf!!! My problem is getting worse and i cant't even drive it anymore.

does your clutch have at least 25% play before disengagement? after my install, my clutch didn't have anyplay at all and my clutch slips because it wasn't fully engaged even when my foot was off of the pedal. took me forever to figure out the problem... also, sounds like your throw out bearing is going bad.. you should of replaced it when you had it apart. might as well change your pilot bearing also.
check for a boost leak. i had the same problem once. drive around and let the piping and hoses heat up and then retighten them. also, do you have the stock cat? it may be since the car has been running for a while the cat gets up to temp and it starts working harder. try running with it off or something.
im running a test pipe,no cat. i changed to a thicker hose from the hotpipe to the wastegate thinking that might be my problem.I ran it on the freeway sine like usual and drive around and let the engine get hot. When i was going on the freeway i was in second and i had full boost all the way to redline. then once i switch the thrid the clutch felt like it was slipping it wouldn't catch at 5000rpms. It did it all the way home and i let it idle.This time I had it in gear and it wouldn't move at all unless it was reved to 6000rrms no joke. wtf!!!!! Its just getting worse
Today i drove it without boosting. It was fine and didn't run into anyproblems on the freeway or at stop lights. Once i got it home it was a different story-3mins of idle. it would not boost and would catch at 2500-another 3mins of idle no boost and would catch at 4000rpms-another 5 mins car would not move uinless it was a 6500 rpms.Turn the car off and turn it on did the same thing.turned it off for ten minutes and tried to drive and it went back to normal. catching at about 1200 rpms. then eventually wouldn't go into boost and the clutch would seem to slip
someone told me today i needed to adjust the transmission since i never did, and i change the clutch to a bigger and stiffer one. doing this will make the throw out bearing or something go in more. he said it might not be the throw out bearing since it never grinds, the clutch also doesn't smell like im burning it when i have my problem too.
