The SRTs are probably owned by a bunch of kids...sad...back to you, although I don't own a Cobra I do know a pretty good bit about cars in general, I (from what I've read) believe your BIGGEST gain would be from a set of 3.73 gears, that mod alone w/ a better launch should net you mid 13s on street tires and porbably give 1-3 mph on your trap. As far as spinning and still trapping 98, to me trap is more indicative of your cars real potential, trapping 98 is usually good for a LOW 14 or HIGH 13, on street tires it can be hard but as long as your trapping well it can help you understand about your car, now et is more of a drivers/ skill number, 60% of people could probably hop in your car and trap 98, but only say 40% could actually get it to hook and run a good et. Hard to say, I'm going back out to Reynolds this saturday and hoping to be trapping around 103-104mph BUT I only hope to get a 13.9 on my 18" wheels and full interior-why, cause 1 st immediatly breaks loose and spins and when I shift to 2nd my car spins to 6krpm and just spins until it hooks then its time to shift, hell, I can be riding about 30mph in 2nd, go full throttle and it spins
I don't even expect to pull 2.1 60' due to how my car was stock (I only got 8lbs of boost in 1st then 12 in 2nd as opposed to 15psi in every gear now, wheelspin has become a big issue) but I really hope for 13.9@103 or better. I say stay out of the water if you're on street tires, launch around 2500-3000rpm and do not dump the clutch, actually slip the clutch some to help keep traction (you will feel like your taking off slow but you WILL cut your 60' down tremendously) and then full throttle, slam 2nd and hold it until it stops spinning then just go w/ the flow. Some don't believe in slipping the clutch I do...on street tires, and if you want to help the life of your tranny. I think if you try my method a few times and get the hang of it you'll like it and pull some really great times. As far as your quest for mid 13s, seriously, I would only by
suspension, exhaust, a
k&n filter and a set of 3.73s. If you can't install the gears it WILL be worth the $$$ to install although at the time it might not seem like it, once you drive it for the first time you'll thank me.
