Default Define Powershifting...

Me and one of my friends were arguing about this the other day... He drives a Mach 1 with a hell of a clutch and talkin about how powershifting is so hard in his car and im like **** powershifting is a breeze in my car.

So, in your guys' opinion, what is the "correct" was to powershift?? Thanks

With the trannys in our cars, that would be never lifting off the gas pedal, while depressing the clutch and tagging the next gear as quickly as possible.

Old school powershifting was said to be done by slamming it into the next gear without the use of the clutch at all. Do this a few times in a synchronized tranny and I hope you have some money for a rebuild....

Easy, no clutch, or side stepping the clutch. With minimal downtime between gears obv.

That's the only powershifting there is. Ripping on the shifter isn't powershifting.

Dude, gas to the floor is a must! It's the whole point. I didn't even bother mentioning that in the first post.

Best method = WOT, side step the clutch and rip the gear. It's all in the timing.

sliding your foot off the pedal at the bottom and letting it pop up as fast as it can. In the old days guys used to take the rubber pad off the clutch peddle so it would be more slick and drive with leather soled shoes and hit the clutch with a glancing motion.

Is not taking your foot off the gas while shifting, hard on the tranny and clutch?

That's all she wrote.

Here's a good one for you. http://videos.streetfire.net/search/...7b1d1ea64c.htm
I was specifically trying to find a guy in a '70 Chevelle with a fuel injected 383. He is in second LI Extreme street racing DVD.

Anyways, listen carefully and go off that. You can hear him WOT, side step quickly and rip the gear at the same time. Practice on a **** box, then fine tune your skills on your Camaro.

Yes, mostly on the clutch. The idea is to do it quickly.

Thats how I'd define it as well.

Accelerator to the floor, blip the clutch, and grab the next gear

In my 71 Nova I ran back to back passes(several) and I picked up exactly .2 sec in the 1/8th just from powershifting. Yes is hard on the synchros and clutch.

Power shift ---> No clutch
Speed shift ---> Blip the clutch

(Of course this is without taking the foot off the gas)

This was what I was told by a couple of guys.

That is not correct. There is no way that a synchronized tranmission will ever go into gear, under WOT, without using the clutch. If it did, it would eat itself on the first pass.

Power shifting is called "power" shifting, because you are shifting under full power, WOT. You still use the clutch, but you do it as little and as quickly as you can.

Any other terms are just randing guys making up their own s**t.

I didn't say that my opinion was right, I was just repeating what I was told. I would never attempt "power" shifting my car, hell I haven't even tried "speed" shifting yet b/c I'm afraid to tear the tranny up.

If you're going to powershift your car and beat on the trans, be prepared to get a rebuild.

If course, the permanent solution to that would be a rebuilt T56 with cryotreated gears, triple cone synchros, heavy duty internals, ect, rated for somewhere around 800HP - just to be on the safe side

I think my T56 is going to need a rebuild in the not so distant future, it likes to grind 2nd, 3rd, and 4th on occasion if I shift it fast. This is especially true when the trans is cold.

Or, you could buy a pro-shifted T56.
