On the last run of the night i heard the supercharger whine get louder, so i took it easy for the 70 miles home. The next day i checked ,smoke test and water test found a manifold with a blown gasket,, replaced the gasket,, the screeming of the engine got louder and idle was now 4000 rpm,, took it apart again replaced the gasket a second time, now i here the whine only when you raise the rpm,, so i remove the other maniflod,, yep, it was leaking also replaced that gasket, now idle is correct ,took it for a test drive runs great now back to the track next wed. 2/10/10. oh just so you know i made my own gaskets from gasket material, I also have a set of stock gaskets if needed. also found a lot of oil spots on the back bumper , any one get that before.? jim
