Great job on this build Jeff! I just have 2 questions:

1. How are you running 16+ psi on the stock EZ30 cylinder sleeves with no problems when OutFront Motorsports told me these motors *need* their closed deck conversion for any boost above 10 psi?

2. Could you still run 16 psi of boost on 93 octane pump gas with no knock on your ez30 setup?

Thanks

I don't see an answer but if they are 8:1 pistons, 16 psi should be no problem.

How much boost could a stock EZ30 take with water/meth or E85? Spec's say it is 10.7:1 to start with.
