what???? what about the supporting mods? What power you think your going to make without them?
heads assembled $1750
Cams $600
Head Gaskets $100
Headers $500
PP TB and Plenum $200
Tuner $350
H pipe $250
Exhaust$500
Long tubes $500
Tune$400
Not to mention Most anyone can put on a supercharger but what about these parts? 95% will pay for the Header install, Head install, and degree the cams. So add another $1000 for that, if not more with the degree
TOTAL $6250
and your comparing that to a base supercharger kit for 3g's that needs none of those supporting mods to make that power? How exactly do you consider that getting ready to outwin.
Maybe I'm wrong here folks. But I've seen lots of stangs....And lots on the dyno. Not just my car or some buddies car. That number is considerably higher than I've ever seen in person. And to suggest that someone did 375rwhp with a bolt ons is funny. That's simply not going to happen. Your not going to take a patriot car like mine, fox lake, or whatever heads you may have and add 35-60 MORE hp just by swapping to them. Simply not going to happen.
In cases like the OP who put down way more power than I've personally ever seen on a simlair modded car I can only say that the chances are higher we have something dyno / operator related to those numbers than the chance that this car is a complete freak defying anything else I've ever seen by such a large margin.
Besides.....Post back up with a track time and then we'll know the real story, I'll be interested to hear if you'll track the car. Dyno's can vary greatly, track times don't lie
