how do you guys shift when your racing do you drop the cluch when starting and does anyone double cluch or have any other ways.
thanks mike

 

Why would you ever double clutch a Corvette?

 

i dont know i was just talking to a guy with a 2000 mustang bullit and he said he double clutches when he races

 

Well that's a Stang owner...

You will need to find out what launch procedure gives you the edge between bog and wheel spin.

Down the track just power shift it for the best times, or shift normally to be safe.

 

He must have a transmission built before WWII then.

Me.... right foot to the floor and jab the clutch with the left while pulling the shifter.

 

Doubleclutching is for trucks.

I love how people try to find ways to shift better, the way SCorp describes is the only way.

Every car and driver is different, you have to find your spot.

Here is a video of me and how I do it.

and sometimes I do spin off the line

Nice!!! videos!!! I have a 96 LT4 and once I launch... my right foot never leaves the floor board. If you have crafty footwork and can stab the pedal and jerk the stick kwikly... you will only rev 200-300 rpms during shifts.

pretty nifty shifty
(it's the chevelle from pump gas drags, for those that have seen it already)
His shifts sound like an F1 car.

Nice videos Mojo!

 

Great Video, but man I'd hate to redline my stock motor like that...
But F*** oh dear what a ride!

 

Is that a backfire when the Chevelle shifts?

It's a stick, right?

 

yea if thats a stock LT1... wow, high shifting!

 

WOW that was hard core

 

How much do you shave off the ET that way?


I haven't tried it yet, although I've done a few where I got back on the gas way too early with the clutch still in, so that's just as hard on the tranny and drivetrain, if not worse.

Now is as good a time as ever to learn, since I plan on rebuilding it this winter.

 

The Chevelle has a 5 speed, one of those where you don't need a clutch to shift. The backfire is from the nitrous.

I rode behind that car in the ride and drive portion of the Pump Gas Drags. That car was so loud it was shaking my buddy's vette and we were 30 feet behind him!

Yes my LT1 is stock and that was nowhere near redline. The factory tachs are off by a few hundred rpm, I really have no idea what RPM I was at, but I do know that I didn't hit the rev limiter at all which is set at 5800.

 

Not powershifting... lifting on the loud pedal? why? its the only way! Although a good safety net here, is to make sure your rev. limiter is functioning and set correctly (drive shaft loop doest hurt either)

As to the launch, its always about being hooked (bolted)
Ever watch what guys in SS/AS to PRO/S do ... now that is really scarry, leavin the line at valve float w/a 500in. motor and hooked

I Watched Mojosfirst video great job! I agree W/Mojo, it doest sound to me like you were wound up (motor) that tight

 

P.S. Do not powershift while in a turn.

 

Point of order. Do not turn whilst on a dragstrip. Except to head for the pits at the end.

 

I just put mine in D, lean back and grin. Seriously, those are both COOL videos. They took me back to the days of my '66 Impala SS.

 

Double clutching (a.k.a. rev-matched shifting) is for downshifting, I do it all the time, it is SO awesome when you learn to do it. Most people mention it within the context of heel-toe downshifting, which is awesome X1000, but it's easier to learn to do when you are simply downshifting, like when passing another car on the interstate.

First, press the clutch pedal, and put the shifter in neutral. Then, (this is what most folks leave out) let off the clutch pedal. Rev the motor to whatever RPMs THE ENGINE WILL BE when you engage your chosen gear. As soon as she hits the correct RPM, push in the clutch pedal, and select your gear, release the clutch, and take off without upsetting the balance of the car. It's beautiful and the most satisfying part of the driving experience, in my book. It's real easier with a lightened flywheel, ultralight valvetrain, and underdrive pulleys, all of which allow the revs to drop and climb faster while in neutral.

The whole "double-clutching when drag racing" buzz is totally contrived and comes from a line in the Fast and Furious flick.
