ME WANT BAD!!!!
Thats just insane. 500+rwhp at 6 psi!!!

Very impressive numbers, but I'm not sure those engines will be able to take any more than 6 psi. Remember, they have 11:1 compression. Now, when people start throwing dished pistons in there to drop the compression ratio, we'll really see those things shine because the heads are so good.
