I've not gotten the guts to power shift this car yet. It's still got the stock clutch in it and I drive it to the track and drive it home, so I'm always paranoid I'll blow up the trans if I do it. So I'm off the gas, on the clutch, shift the gear, off the clutch, back on the gas. In one of my data logs it shows I take .8 seconds to shift and I have to shift three times. That's 2.4 seconds I'm not putting power down, and in that log I thought I had shifted pretty good.

It sounds like your power shifting that car...is that correct? What's your car weigh with you in it? Mine's right at 4350.

Here's my PB run:



How'd your buddy's 5.0 do in the mile?
Thanks man! Believe it or not I lift shift too. Just doing it as-fast-as possible. The new clutch and shifter helped a ton for me. For a car such as yours with the blower, you want to keep it in the boost the entire time. To accomplish that, power shifting is the only way using a 2 step rev limiter so you don't hurt the motor. Something like this for example: http://www.lethalperformance.com/201...ot-box-p-33643

From the sound of it, you have quite a bit of ET to gain still. I would recommend moving away from a drag radial and over to a bias ply tire. Manual trans cars hit the tires harder on launch and a radial tire does not respond well to that. I know you are size limited but there are several manufactures that make a 17" bias ply DOT drag tire. That will help you more than anything.

For the burnout, I wet the tires in the waterbox, roll out a couple of feet and dump the clutch while at the same time hitting the brake pedal with my left foot. (no line lock here) Here is an example:


Same boat as you, drive to the track, swap tires, run, swap back and drive home. Not sure on the weight as I forgot last time to roll over the scales at the track. I would venture to guess around 3,650 with me in it. Our Challenger was 4,280 with me in it on that 13.4 run.
