89? I think

I think it has got to be a leak. Or either operator error with the boost controller installation/operation. https://www.nopistons.com/forums/pub...IR#>/dunno.gif

https://www.nopistons.com/forums/pub...1047683561.gif See the thing is... Everything worked until he upgraded the turbo and got the wastegate ported... Boostcontroller and everything was good until then... https://www.nopistons.com/forums/pub...1047683561.gif

if its 89 tell him not to blow it up and if he does blow it up i'll buy it off him https://www.nopistons.com/forums/pub...#>/biggrin.png

Bump. Still no fix... Anyone?

Tell him to look at the wastegate, and make sure that is is not overly ported, so that the opening goes past the closed door. Also have him hook a pressure/vac pump up to the actuator and check for movement. It could be a restrictive intake, but it sounds like a boost leak. Have him try this:

I've found that the easiest way to find boost leaks is to take some soda cans or tennis balls or anything of the like, and put them in the intake hoses(from the airbox to the turbos). Clamp the hoses tightly around the cans. Next, get a blower nozzle for an air compressor that can have a vacuum hose slip on. Put the vacuum hose on the blower nozzle at one end and an intake nipple at the other end. Tighten the vacuum hose down with hose clamps at both ends. Turn the car on(not the engine though). Now lightly blow air into the intake with the blower. The air will have no where to go except where the leak is

If he finds a boost leak, make sure he doesn't go out and hammer the piss out of the car as soon as it's fixed, because the motor probably won't like all that boost.

Thanks... I'll forward that to him. https://www.nopistons.com/forums/pub...#>/biggrin.png

Did he somehow fit some huge compressor on it? I can see the stock hot side not wanting to spool a large compressor up very high.





That doesnt seem very likely though. I'd check out what everyone mentioned above.

i believe viagra could be used to help get it up.



kevin.

OK he upgraded the turbo and ported the wastegate. . . what about the spring rate in the gate? If it hasn't been increased it's not going to hold more boost.

Which wastegate is it? I've had some trouble with some of them not having stiff enough springs to hold much over 10psi, just for a heads up.
