hey guys i have a question... if i make my shaft aluminum would it widstand a twin turbo? cause im making it intoo one but i dont know if it'll hold... and do i have to replace the pistons and rods, cam shafts?

 

how much hp you aiming for. there are aluminum DS that can hold plenty hp. i dont think the cam shafts are necessary but will help, the pistons and rods are probobly a wise idea, but all depends on how much power you are going to run. above 500 rwhp, a forged rotating assembly would be advised.

 

 

If your DS is aluminum what was it rated for? ask the manufacturer first...... also if going with twins I would forge the internals at least and up the boost to 30 psi and have a 1000 hp monster.... hope it helps...

 

Gotta give more details!!!

 

The dynotech 3.5" aluminum DS is rated for 900 HP but has been used on cars with more. I think it'll work.

I'll be installing the dynotech real soon.

ok guys... change of plans... one of my friends is going to get me a roush supercharger stage 3... my car only has 62k mile in it.. would i have to forge the pistons or would it take that power without messing with the internals...?

 

As long as you stay <= 450 rwhp you should be fine with stock internals. Some people run more with stock but I wouldn't.
