I know thats more of a Sam question but I know you guys talk alot more then me and him. Last, Sam tore apart your engine, what do the internals look like, meaning what are they made out of, meaning are they forged. Just wondering if this car can handle more then 12 psi, or can we use 12 psi more often then a few times. personally I only use 12 psi when I know I am going up against a tough car. In other words I get scared when I turn the boost that High because I am afraid I am going to blow the engine.
Thanks MIke

Hey Toner buddy!

Ok, my intake on the car right now is the prototype for a new intake going to be made

I cant go into much detail because our conversation was very brief on the subject.

Sam did not tear apart my engine however, he did have a spare 4.5L stroker short block laying around and we made all of the mods to that motor. from my understanding the motor can handle the stress levels that of a car putting out 12 psi. However, your longevity may be at risk with that motor. from my understanding the internals in our motor are slightly beefier if not the same as the 3.5HR motors. From their history they are fine up to 12psi...

hope that helps
