Thanks guys, I did check out Bob`s page. I agree that the results seemed a little lackluster for the effort he put in. It would seem you could get 200whp out of a stock GT with more boost and enriching the fuel curve (and obviously the typical bolt-ons). I have seen 4 cylinder motors make 400hp with a well tuned turbo system.
The hahn kit just seemed an easy way to pep up the horribly underpowered PT. I`d be happy with bolt-ons if I could squeeze out another 20hp, but I`m finding out that the power just isn`t there to let out...
(and to be completely off topic, but worth noting, I just replaced the starter in my Cruiser yesterday. Took about an hour and was MUCH easier than I thought it would be.)
