Yes, as the cracks generally form where it seals on the tube.

also i only saw 5.5psi boost. maybe cause the ect was 192* and IAT was 102* when at a stop it can reach 150+. i ordered the heat insulator to wrap my intake pipe and make a air filter shield. also bought the stuff make a duct for cool air outside to enter.

Viton is a bad idea on a high-mileage SC. The long miles have worn a groove in your input shaft, and the Viton is too durable and stiff to adapt itself to that groove. I suggest using OEM Nitrile.

Leaking oil and a bad coupler won't cause low boost, but oil on your belt will cause slip and low boost.

I'm moving your topic to 92-99. This seems to be much more about mechanical problems on your car than it does about performance ideas.

You need to get the car running right before you even think about more power.
