where can i get the best heat exchanger and what is the bigest upper pulley i can put on a 03 cobra with heat exchanger,exhaust, intake and a tune?what rwhp will i be with all that?

spray175

Afco heat exchanger, you mean smallest pulley I think which would be a 2.76. That will put you in the 440-450rwhp range.

LFP and Fluidyne are both good brands to consider for a HE. I'm personally going with a LFP. You can run a 2.76 upper pulley like spray175 said... just make sure to get a good tune for that and the other things that you listed you wanted done. Its possible you could be anywhere around 440-480 rwhp. Thats about all you will see until you either port the Eaton or upgrade to a Whipple or KB.

did you get it with a stencle??

It's the Extreme Dual Pass H/E, no stencil, I didn't look closely enough at the options, didn't see it [:@]

Nice choice. I have the LFP dual pass. I have no comparison or proof that it works any better but I've seen many threads on svtperformance. There was a test done by a member and it was said that the LFP dual pass cooled the intake temp by about 3-5 degrees over other aftermarket heat exchangers. If that's true then it's a very nice piece.

Also for the poster, I have a 2.95 pulley, bassani cat back,bassani x-pipe (no cats), JLT intake and an SCT tune and put down 447hp and 458tq. I was honestly not expecting that much power for the pulley I purchased. This was on a mustang dyno as well.
