Thread: Turbo Help!!!

Turbo help:
Setup: W10 sr20det, 1.75" piping, open SSQV

Idle OK!
Starts OK!
Rev OK!

So when parked i can rev the motor till red line and it will drop and idle normaly.
I drive like a granny and the car doesnt die or anything.. works just perfect.

As soon as i mash( drive hard) on the gas (boost ~5krpm) and hit the clutch to shift gears the rpm drops all the way and dies. on any normal DET, No problem, just Drop in 2 second gear and let go of the clutch to roll start it and it should be fine. So i try to do that and the car starts/runs.. but as soon as i press on the clutch the rpm drops all the way and the car dies(doesnt idle) .. So i have to completely stop the car and start it with the key and it runs again and idles.

Why i dont think it's these issues.
Flywheel Iv seen cars die from a light flywheel, but thats no the issue because when roll-start the car it still will not maintain idle.

BOV why i think it's not the open SSQV is, all the BOV will do is run rich for that moment and bogg down or kill the engine.. but i dont think thats my issues because when i roll start it and let it idle my pressing on the gas for 5 second and letting go to see if it will still keep idle, it just dies.

IACV it's not it because when parked it idles perfectly. revs perfectly..etc. and i know its working because when i disconnect the hose going to my intake tube it boggs and dies.

Any help?

Vacuum leak.

Pressure test your system.

iVac leak? i dont see how pressure testing will help since i'm experiencing problem when in motion+boosting+throttle body is closed. If it was a vac leak the car wouldnt idle at a stand still and when not boosting.

Not necessarily true. When i had a boost leak my car would idle fine, rev up nice n smooth, but under load would bog.

I say boost leak, check your piping for cracks, n splits. All it takes is one tiny split.

im thinking boost leak also, check to make sure your ssqbv is opening completely and is coming off a good enough source.

Boost leak. My car was doing the same thing when I blew one of the tuning nipples off my ITBs.
