So..I'm a tad confused on what might be the issue? IF anyone can chime in or help me out..it would be greatful!!! So the car just finished an aristo engine swap..from a N/A-T setup..and everything goes smoothly in the dyno and on idle. It went through 2-3hrs of tuning on the dyno..and nothing. The PS pump however, is making all sorts of noises, when turning the steering wheel. We just figured the pump is going out..and that can be replaced later on...It will sometimes go on/off. So we tried to keep rotating the wheel..to maybe release some air in the system. After 1hr of doing so..it still does the same thing. So we wind up taking it for a spin..and within 3-5 minutes of min-moderate boost levels..the water pump housing cracks.
We reinstalled a new one..and same result. It is a USDM TT water pump, and the belt and tensioner looks good. All the goodies are there..a/c, alternator..etc.etc. The clutch fan..has however been extended (studs) to bolt the NA radiator fan. We put plastic washers on it. What might be the issue? **2-3hrs of dynoing..and all is fine**
