Default Help! Optimal shifting for WRX to clock < 6sec

I am sure one of you guys can help me with this rather vexing problem -

I bought the WRX a couple of months ago (replaced my old car that had auto transmission) ... I thought I was pretty good at shifting.

This morning I timed myself on a empty stretch of road ... I am too ashamed to say how bad I did :-)

I would like to know how to optimally shift this thing so I can come close to the 0-60 in 5.8 seconds that others in this forum have clocked.

Thank you !!!!!

Max

You will probably have to dump the clutch while holding rpms at about 4k. Very bad for the internals, but if you want the time....

...same way in my last car, had to rev high and dump the clutch... shift fast, but not too fast to let the DV stick open and vent boost.

Good luck, just weigh the consequences... and wear...!

I haven't timed myself, but what I normally saw recommended around here was redline in 1st gear, 6500 in all other gears. Which probably won't apply for 0-60 because you'll reach 60 in 2nd gear, but it would for the 1/4 mile.

There was an interesting little article in the latest issue of SCC illustrating that most car manufacturers seem to set up the gear ratios to reach 60 in 2nd gear. It's basically saying that they optimize the gears for the benchmark instead of real world performance. Almost like computer manufacturers.

I don't know about that... When I'm on a short twisty on-ramp (you know, the 270' kind that you can only go 35mph around that straightens out and gives you 60 feet to merge after it straightens out), I like having the gearing optimized to reach the speed limit (60, where I live) as quickly as possible.

Boostaholics guide to pimping the 0-60:

Launch - Two options:
1.) The slip - Rev to 5k, move clutch halfway then slip in... produces 5.7-6.0 0-60's and your clutch wont last long.
2.) The drop - Rev to 5k and drop the clutch.. this is the best way to launch (actually I prefer 6k) and produces 5.4-5.6 second 0-60's with 15 psi. It takes a cordinated effort of your feet and the gas for optimum results.

Shifting:
There is no doubt you should shift at 7000-7200 rpm in 1st and 2nd gear. I do NOT take my foot completely off the gas when shifting, play with how you release the clutch also so that you get the most mph gain on the shift.

My best 0-60 so far is 5.34

Thanks Guys for all the responses:

I guess I was being too cautious with this pooch. I never went above 4000 rpm on any gear. That explains the slow time in my case.

I will give it a try on sunday morning when the folks here in South Carolina are at church. I am assuming the cops are no less religious around here.

Later.

As has been suggested earlier in this thread. You may be doing serious damage to your transmission by doing the "dump"

The Slip saves your transmission for the most part. Clutches are cheap and it will last long enough.

Default wrxburnouts and dropping the clutch.

ok... i assume tht duming the clutchand popping it are the same things. but how fast do you let out the clutch bcause when i have tried... it stalls. maybe too quick. i am almost just sliding my foot to the side so the clutch just pops back up ( thats not what i do but that is probably how fast i reales the clutch at like 4500-5000 rpm) but it stalls .. someone kinda give me some pointers a launching the car and how quick to let out the clutch. also... is it possible to do a 4 wheel burnout... the awd stiker on the back of the car would lead me to figure that it is near impossible withot beaking the car. thank you for all comments

SDaWG ... as far as the rate of release, I can't really describe it. I wouldn't consider it being very fast. I used to be a victim of the evil bog. I've found that if you bog, slip the clutch more or rev it higher
