Just want to share new results. Another dyno and 400hp still not reached After I came back from dyno I found out that my external wastegate vacuum hose that goes to turbocharger snap off from fitting and that is why I could not raise boost. But this dyno is good example of different turbochargers and different power band. Almost same boost. On old turbocharger it was 9psi on new it was 9.9psi.
My old turbocharger housing was .63 a/r (good low end, bad top end result, car was more fun to drive once you step on the pedal it would just take off like on NOS)
New turbocharger housing is .83 a/r (bad low end, high top end result, it opens up on highway nice but you have to wait for the power)
This time I run 360hp and 314tq, back to back after few runs. I raise boost to 11psi after fixing the vacuum hose and the car was wild, but have to dyno again to see it on paper. I have all my components beefed up so I can hold up to 14psi but I'm taking it easy. Boost is very addictive
