Default 8.6:1 347 with 14psi,any thoughts?

My goals with the car right now are about 600rwhp through a 3000k stall and 9 inch. Its a single turbo (presision 67) with fmic. Im going to run this turbo kit for a season just to get introduced to FI and then up grade to something alot bigger.

Is this compression to low for me now?

I think the comp is nearly perfect for pump gas but I'd go with a T76 at 14#s boost with those cubes and power level.

That turbo may be the restriction?

From reading over the years, my spidey sense tells me that you will run out of turbo before 600rwhp. Let it happen, and then upgrade. I'm sending you a pm on something else.

You know what im pretty much counting on that turbo running out of juice and upgrading to a 76mm. So everything things the comp is perfect considering ill probably upgrade turbo very shortly after?

I'd sell the turbo and pick up the T76 up front. Why waste time/energy installing/tuning a setup that you are going to change?

through a 2OTL exhaust and 12 bolt, in garbage air.

It wont cost me much more to tune it with another turbo later. I already have the engine,drivetrain, fuel to handle much much more. I like testing different things and im always changing setups. Its a part of life for me.
