I can't wait till I go get Dyno'd. I hope by then I'll be at 300. I figure mufflers and x-pipe is what I'll have by then. The suspension mods won't make the HP so I can't count that. Do you think it's possible with the mods that I have now?

I'm waiting for a dyno day from our local shop. It'll probably be around March or April since I get that done. Hopefully I'll have some more extra cash to put into the car.

I dunno, those numbers seem weak to me. Go over to Mach1registry.com and check out the forums, people have put down better numbers than that stock...

the 99 were down on power that year had recall,,they didnt make a cobra in 2000 ,,2001 they got all the bugs out of it ,,stock 99 cobra had only 256 rwhp acorrding to pauls hi perf..dyno!...so im happy with my #s because the long tubes made up for the factory loss h/p...dont get me wrong the machs i seen in mags where dam close to mine,,,but thats new tecnogly...
