    Nice. Is that on drag radials or streets?

  3. That would be on 17" BFG drag radials. It'll probably do high 11s on street tires. Never tried it...kinda scary off the line on street tires :eek:

    If that were on streets I'd be amazed. :eek: Still, excellent numbers. I heard Mustangs have problems hooking up, so how bad is it?

    No one with a high performance car leaves the stock gears in - they usually go Tremec and get a Pro shifter on the older Mustangs. The new Cobra is well equiped in this matter though, but still has a couple of "problems."

    Look at the specs. One thing to notice is the shitty first gear ratio at 2.66 with a final drive at 3.55! No wonder they have a hard time getting them going on launch. Put in 3.75's or 4.10's and that will make a HUGE difference in launching the car (the downside is "bad" drivability at highway speeds.) The second thing to notice is the weight of the vehicle at 3,665 - pretty heavy.

    I saw a review that said the Mach 1 is faster off the blocks and faster to 60 MPH than the new Cobra - not suprising as the rear end on that one is a solid axle as opposed to the Cobra's IRS, plus different power ratings along the horsepower curve.

    Finally, notice that this car is almost $20K less than a Z Corvette. Put in a bigger CAM and take out the back seats, put in a fibreglass hood, and now we have a contest...

  8. Actually, the computer (PCM) does need to be reprogrammed for the supercharger. My car is N/A and it still needed computer tuning.
