I BUSTED "JIMMY WHEEZE"!

When I floor it at speed in third gear (50-60mph) it shots up to 19-20lbs (where I have it set) and pulls like a freight train. Then all of a sudden it starts to studder and the boost drops down to zero and it makes that intercooler sound like when you pop your foot off the gas. It doesn't do it all the time, but it also will do it if you ease into boost.



I have two adjustable wastegates controlled from inside the car and it locks my boost where I set it.

My hood mounted fuel pressure guage stays at 60+lbs even when this happens so I know it's not fuel.



It always ran fine but I did explode my turbo side hose on my front mount racing my sons Hennesey Viper GTS @130mph @ 25lbs of boost a few weeks ago. (I have Razors Kit on my car that works fine) That hose was replaced with a good 6ply elbow hose.



The other hoses that are on the Turbo-Intercooler-Throttle Body are old but seem O.K.

My intercooler hasn't been cleaned out in years, could I be sucking up oil?

I hope I didn't hurt the Turbo racing my son.



HELP....any Ideas ???????

Help - same type issue!!

I am having this same issue with my 86! I just had the brakes converted to a vacuum system due to nightmares with the original system. I am afraid of ruining my turbo. :(
