Power shifting Q?

I hope that most of you have heard of power shifting... but anyways I was wondering if anyone had an idea of how much damage it can do to the clutch and engine, and if I did start using it for racing, what would be an estimated time before I had to change the drivetrain and all of that?

Your talking about keeping the gas down when you switch gears, right?

Don't do it. It's not worth it.

Are you talking about not using the clutch and just slammin it in gear?

Its not good to do, but i always did it in my car... Certain RPMs it will slide into gear, but not ***** to the wall racing...

I dont clutch the bike either... unless im down shifting...

I have done the holding the gas down while putting the clutch in and shifting several times, as did the previous owner. Never had any issues, however I don't do it anymore because I don't want to hurt anything. It really doesn't do that much for you. Some diesel guys do it to keep they're boost up, but don't matter in my case lol.

If you mean shifting without the clutch when at that sweet spot where it will go without grinding, I don't think there is any negative effect. In fact, it is that much less wear on your clutch. When I had a stick, I did it all the time. Almost all my shifting was without the clutch.

A guy at my work has a chevy truck he loved to shift hard and i mean hard burn outs. Leave on the gas and let off the clutch, well 4 years later it all added up, Wasnt the transmission or the clutch or even the engine, He blew his rear end, Smacking those gears together when there not intended for it will take its toll over the years and something will give.

this article pretty much sums up powershifting and how it is done, what it is used for, yes does hurt the car quite a bit.

That is vastly different than the nice gentle clutchless shifting I was talking about. I'd probably blow something up if I ever tried to do that.

And the Ricers wonder why they go thru clutches so quickly. The "ripping" thru gears could probably have a big part of that.

Hahahaha, and if I cant get that then selling truckand maybe getting a car, would rather be lower to the ground anyways... by the way on the clutchless shifting at what rpm would that be or does it vary?

ok... should have noticed this before and told ya mazdaman, but thats a '98... and from what I have heard aren't they wider than what my '03 is, so it would fit a lot easier in that... if anyone knows I would like a response.

its easy to stuff a motor in the 83-97 rangers, anything 98+ and you will have to custom make a lot of parts/mounts.

use the search feature.

In the early 1960's Ford decided to build a 4 speed tranny to stand up to their 390ci 390hp engine. It was required to withstand at least 5 dead stop take offs by holding the throttle on the floor and sliding the foot off the clutch. That was the beginning of the much sought after 4 speed top loader tranny.

To do real power shifts is a learned skill that costs many clutches, trannys, drive lines and rear ends by many. In my teens and early 20's I power shifted with techniques according to each engine and tranny.

A fast reving engine can get you in trouble power shifting because it will over speed by the time you punch the clutch and shift to the next gear. If you attempt to shift without the clutch by lifting the throttle and jaming to the next gear it may not go in and the engine may blow.

After rebuilding several trannys and replacing one ripped out flywheel I settled on a method that worked for me. At that time I had a '51 Ford with a near full house Flathead V8. I found that if you slightly lift the throttle as you clutch and shift the engine did not overrev and was at the right speed for the next gear. I had 3, 2 barrels with progressive linkage and I would lift to close two carbs while shifting. What you don't want is a bang and jerk when you shift. You should feel a surge but not snap your head. It should feel like a steady acceleration to the end. If someone is speed shifting and it hammers at each change they will tear up stuff and NOT be faster than a smooth power shift.

In 1966 I bought a 66 Mustang fastback with the 4 spd top loader. They don't speed shift well. There was some brass syncros you could get to make them shift faster but you had to jam them in gear to keep them from grinding on normal shifts. The Mustang ended my speed shifting although I did learn to shift it pretty damn fast.

You have to really know your engine and have a fine feel for when it tops out on torque and make the shift at or just before then.

As I said, it's a learned skill and not many are able to master it and take the jerk out of it. Did I mention my uncle had a speed shop and helped me along?
