here my dyno sheet for 99 cobra when first got it..only mods then were long tube headers off road pipe and mac mufflers,,and stock type k/n air filter...

 

daaaaaaaaaamn. i hate 4.6's. lol j/k. nice #'s man.

 

Scary, I've seen stock Mach 1's put down better numbers. [&:]

 

Im close to the 285 mark now... I hope.

 

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?

 

no way![&:]

 

with all you r mods you should bee over 300 ...since that dyno i got 62 mm TB.pulley,,3.73 gears...just had not dynoed agian..no chip by the way or cold air kit ..waiting to rebluid motor first then add kenne bell unit.it s smoken a bit ...

 

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...
