On The Drag Strip.....

My question, how many people paddle shift at the drag strip? Meaning, never letting off of the accelerator during shifting. I have a feeling that my 8.40 at 82.5 mph will be significantly lower when paddle shifting. I actually think that I will be close to 8.25 at around 84.0 mph on the 1/8. Any takers?
 
I believe you're referring to power shifting. Paddling shifting is done using paddle shifters, like on Ferrari's and Evo's.
 
I usually let off on my 1-2 shift, but for your 2-3 and 3-4 it shouldn't be too hard on the tranny/clutch, as long as you can shift fast enough.

I personally have never tried it on the strip, but on the street it seems to help a good bit since it keeps my turbo spooled. It probably wouldn't be as beneficial on the stock K04, since it spools so quick.

"K04" is that the stock turbo?

and are u guys talking about shifting gears while still having ur foot on the gas?

and if so how much on the gas, floored, or just a bit of preasure im qurious i've never even thought of that.
 
I've tried it, I didn't see any benefit, and although it didn't seem to hurt the car, it sure did sound like it could!!! I'll never do it again, tried it on 3-4 runs

Yes, ko4 is stock, and yes, powershifting is keeping it floored
 
If you shift quick enough you dont give the engine time to rev high. I doubt a few times is going to hurt but I would imagine like anything else if you do it enough you're going to wear it out quicker. Just like how another thread was talkin about keeping one foot on the brake and the other on the gas so you can keep the turbo up right before you race from a roll...

You can also shift without even touching the clutch..although theres no real benefit.

Brake boosting (holding your foot on the brake while spooling up your turbo) is not nearly as bad for your engine as flat/power shifting is. All you are doing is putting load on the engine using the brakes, thus wearing down your pads a little quicker than usual. It is almost necessary when racing someone in the upper gears when you have a larger turbo, it takes a while for that b**** to spool.
 
How is power shifting hard on the engine? The tranny will get abused if you are not smooth, but the engine?

For a good shift you would be better off holding the RPM's at the point of clutch disengagement, which usually means a very, very slight lift of the throttle and then a smooth clutch slip while pressing on the throttle. Do it this way and you will only feel the car pull hard, no hesitation or bump.
 
I've tried power shifting on a few occasions to test out the response. I, for whatever reason, have not experienced any fear or "extreme engine rev" or a knocky tranny shift. I'm not sure what you cats are talkin bout'. I think I'm gonna try it the next time I head out to the strip. We'll see.
