Cobra2, yes your tyre combination will be more than adequate. I've been talking with Bob at ERA and he thinks that 500ft/lbs of torque is about the limit in terms of being able to smoothly get the power down without uncontrolled wheelspin in a well set up Cobra. I will be going for a little more than that and then making up for it by special attention to the chassis tuning and setup, but mine won't be a daily driver, it will be a fine day, once a week or fortnight drive that will get the adrenalin flowing every time I take it out. I will make the chassis very adjustable, and by the time I'm finished will get some very good 60 foot times out of it for a Cobra. Once you can get a good 60foot time, you can then put down some very good numbers as you have the base sorted out to work from.

Even at 380hp, obviously, any sharp transition from trailing throttle to heavy pedal will result in instant wheelspin in the first two gears, but with the power your vehicle will make, you should be able to get all the power down in any gear if you are smooth, and that will make you quicker than a lot of higher powered Cobra's that cannot use what they've got. On a tight track it might even be quicker than my one will be because you can apply power out of corners while I'll have to feather the throttle until dead straight... yahoo! On the 1/4 mile tho, or anything over 60-75mph, I'll take some heading off... grin, mind you, I won't be getting anywhere near 26mpg!
