My car made 917 RWHP @ 30# boost. It didn't pick up much at 35, only 10 HP. I'm looking into everything now but question if I'm out of turbo. Is it possible ?? My back pressure at 35# manifold was about 52#. I The only mechanical limitation would be valve springs. I'm having a hard time believing that it is valve spring related. Any ideas or advise ?
I'm thinking the driveline loss is about 10-15%. I was hoping to see 1100 @ 35#.
