Twin Charged and Cams?

Anyone out there running a twin charged setup with an upgraded cylinder head? Just curious to what Valves and Springs along with what Camshaft you are using.

As of now I have the JE oversized pistons, Fireballed head and Cam. I want to go twincharged but I'm feeling a little uneasy. I should be safe because I have bulletproof pistons and a very flowing head, so to make the 270whp I want I should be able to run less boost causing less strain on the motor.

Come on Mario, go turbo-only. 17psi and 300 wheel

To answer the OP. I am gonna run a stock cam with the Fireballed stage 1 head. You can do a DMH head or a Fireballed stage 2 with uprated valves, reainters, guides and springs. But unless you want to see the far side of 7500 rpns ( I don't on my daily) then it is probably overkill.

BTW, it is a cam not cams. 16 lobes, one cam, loads of fun

I reality it isn't psi of boost that puts the strain on the motor, it's the tuning/timing/a-f ratio.
