Well I just got back from the dyno. Car made some nice numbers considering it was still creeping quit a bit even after porting the wastegate. Its going to need some more porting to stop it. The car ended up running out of fuel when the boost was turned up so we had to stop. I hooked up a fuel pressure gauge and the base was at 45psi or so and under boost it went to around 70psi and held for a little bit but then fell to around 45psi or so. So we are suspecting a bad fuel filter or a the walblow pump is failing. Car has 950CC injectors and a 255HP so there should be plenty of fuel. Injector duty cycle was around 118%.

So anyway the best run of the day the car made 498.1whp and 402.2wtrq, the boost was set to around 23lbs, it crept to 25lbs and stayed there for most of the run. At the very end it saw 26lbs. The timing was also very conservitive because we were battling some knock all day. Not sure if its just a lot of noise but it seemed to go away when timing was lowered. But not bad numbers considering the low boost and timing. The car has a lot more in it once the fuel issues are sorted out.

The car was in the 450whp range all day running just off the wastegate (16lb spring), boost was creeping to around 21lbs by the end of fourth.

This was on 111 from the Mobile station on hwy 65, so who knows maybe the knock was coming from shitty gas too, who knows. Time for some C16 and some more boost.

But hey it didn't blow up.
