Judge, what AFR are you running? Your engine appears to be running pretty lean to put down that kind of power. Working with turbo engines at work every day, I have no trouble believing this power number and the drag strip times, but I do wonder if the engine is riding the razor edge of being damaged with a lean AFR and the stock intercooler.
Basically, I doubt that this much power was made rich of 12:1 and it was probably closer to 12.5:1. This is not a terrible idea, but it is a bit risky.
Please don't let Ted get to you, he is very blunt, but he has a lot of experience and it certainly is not to be discounted. The question that he asked was valid, he just asked it in an aggravating way.
It would seem that you have an excellent-condition stock turbo to hold 9 psi to 7500 rpm on a ported engine. What are you running for exhaust? How aggressive is the port work?
Is the porting a trade secret, or can you provide pictures?
