Do you really want to powershift?

SlowStang2 · 08-25-2001, 04:09 PM

I have never really power shifted my car and noticed a better time in my ET, but then again, I haven't done it too much. The reason why I don't is because I am not sure of how much wear it puts on the clutch\tranny. Does it put a lot of strees on them or not? While we are asking, how many of you out there have gotten a better time or two from regular shifting to power shifting?

A properly executed powershift makes a big difference. I don't have any track times to back it up, but I can certainly use my races on the street to back it up.

If a race is close, I'll powershift. I don't lose ANY ground at all when I shift, in some cases I gain ground on my opponent. If I just shift fast, I fall back a few feet.

Well it is alot harder on the car But I still do it and Like Unit said.

SlowStang2 · 08-25-2001, 06:32 PM

I did not know there was more than 1 way to power shift. What is a "properly executed powershift?" I just keep my gas pedal to the floor while shifting at the same RPMs and releasing clutch at the same times as well.

Severisth · 08-25-2001, 06:41 PM

Here's a little research I did on powershifting a while back:

http://forums.stangnet.com/showthrea...=powershifting

I have gained a ton of confidence in races since I started powershifting. I ran 14.4 - 14.7 before powershifting, then I went back and made a 14.1 on my first run powershifting. There was room for improvement but that was the only run I got in that night. In the eight, I usually ran 9.5; powershifting netted consistent 9.1s.

But I have a TKO.

Unit 5302 · 08-25-2001, 08:07 PM

Powershifting won't make a difference T-5 or TKO. The powershift is hard on syncronizers, not gears.

In a properly executed powershift your rpms should only climb maybe 300rpm. It should be all and done in a split second. If you do it to slow, you'll be basically dropping the tranny, which can cause the wheels to break loose easier. The longer you take, the longer you aren't accelerating as well.

stanger8172 · 08-25-2001, 10:38 PM

For what it is worth, I raced at Great Lakes Dragaway again on August 16. My timing is turned downn to 10 degrees. I just added the Home Depot ram air and got rid of the front sway bar. I thought I would be in the 14's but timing is everything, I guess. My best for my 'vert is a 15.1.

Honestly, If you don't know of anyone to help you swap your clutch out when it goes bad then sc**W it! You need a heavy duty clutch cable to confidently powershift like that. My Centerforce and FMS kit holds up strong all the time. It seems as though the car runs better at high rpm's too.

Get a good clutch and quadrant kit!

90dpscoupe · 08-25-2001, 11:41 PM

True, true, i have a brand new hd fms clutch, but my stock cable is worn, i need a quadrant to take advantage of my nice new clutch, i went 14.1 @98 last week without powershifting, replacing my t-5 was no fun

nor did my wallet like it, besides my little tires break loose when i powershift, and it only gives me about a tenth, not worth a t-5, but streetracing is different

SlowStang2 · 08-26-2001, 06:37 PM

So you all are basically saying don't try it on a stock T-5? That means stock tranny, stock clutch, stock cable? OK!! Ruining my clutch/tranny is never worth a tenth to me, but a race...well it depends on the beneiftis of the win.

While we are addressing shifts with this tranny, lets talk about launching. Now I already had a previous topic on launching a bit back and the advice that was delivered to me was different from what I was doing. I went out last night to try it out formally. Left heel on brake, left toes on clutch. Let out clutch 1/2 to 1/4 way and bring gas to 3k. The clutch should grip and start to move the car, but with brake pressed it will not move. When you want to go, you simply let go out the brake and let out clutch. Well, hmm, in a race this is hard to setup quickly, but i guess thats cuz im not used to it. NOW THE POTENTIAL PROBLEM...as I tried this technique, I noticed i was pretty much wearing the clutch. That doesnt seem like a good idea. Now I didnt smell any burnt clutch, but that was because I didnt want to keep doing it think it WOULD burn it eventually. ANyhow, am i doing it right? Should I worry about anything?

No, for launching its left foot on the clutch and right heel on brake with your right tip toe on the gas. Use your toe to rev, when you are ready to go drop the clutch and brake at the same time.

Im not trying to bust your balls..believe me, but a with all your mods, all you can muster is a mid 14!!??

Unit 5302 · 08-27-2001, 12:12 AM

I powershifted my 88GT for a couple years with no related problems. It had 130k when I sold it.

I powershifted my 87GT for over a year before the tranny went out (I was actually being really nice to it at the time), in an unrelated deal. Both were totally stock driveline setups. (Clutch, quad, tranny, shifter)

Powershifting wears the syncros in the tranny. It doesn't hurt the gears, and as long as your clutch is adjusted properly, you shouldn't have any problems occationally powershifting.

I have power shifted just about every stick car i've ever driven at some point. I have never broken a trans. As for the stock T5, I even borrowed a 100K+ trans with no reverse (I was trying to figure out if a driveline vibration was the trans) & 5k launched & power shifted all night (like 8 passes) 1.5* 60ft & all runs mid 11's spraying the 4hit out of & couldn't break it.
