I was gonna say the same about him having a turbo. It always seems odd to me that he would have a turbo with a sig like that. And there is no way he is running 12psi on a stock motor. The other guy was doing a dyno on 11psi and backed off @ <5k in fear of blowing up.

I would suggest u get a turbo and run it mild for a while so u know what its like and decide if u really need that much more power. Get aquainted with turbos more and then consider building it up for more boost. That is if u have never had experiance with turbo.

 

Awesome man...nice work. Thanks for the pics.
