Mods in my signature. Only change made in the car was swapping the stock Cobra out for the ported GT-40 the same day I made the first run. The torque is a noticable increase and the car feels very strong.

I'll be sending Tom my stock lower on my Saleen this winter to get a little better breathing out of it.

It's amazing how such a simple thing pics up decent gains. I have E7s on my car that i got from my buddy....he did some real minor gasket-match porting just to the intake and exhaust ports...basically just opened up the ends of the ports to match the gaskets and he picked up 11hp at the wheels.

How much for the ported intake work?

I honestly don't remember how much I paid Tom to do the work. It was a hundred and something and I paid extra for ceramic coating when he was done. Drop him a line and he'll give you a quote.

I can only vouch for Tom as well.

I noticed a gain when he ported my Performer lower to match the AFR 165 cylinder heads.

Very nice work indeed.
