Want faster acceleration in your C6Z?

Here is an exercise for the street.

(1) Accelerate strongly without spinning the tires.

(2) Make the shifts with minimal spin of the tires.

This drill helps you to focus your senses on what the rear tires are doing under acceleration and helps you to learn to squeeze the throttle and to not overwhelm traction on the shifts.

This street practice will make you faster at the track.

Maybe my car is weak, but I don't get that much wheelspin. Sure on a cold road. Certainly not a ton on 1st to 2nd shift

Ranger for president!

If you're making the shift near the limiter and still getting minimal spin then you've found part of the magic of fast times.

I doubt your car is weak.

With enough RPMs, I can get my Z sideways on the 1-2 shift if I don't 'squeeze' the pedal and simply mash it.


Maybe you're doing it just right already!

I was in the same boat not getting that much wheel spin for about the first 650 miles. Now im at 900 miles and the car will spin from 3rd to 4th. It seems like either my car is getting faster or maybe my tires have less traction?

What TC mode for this drill?

Jagcvette

Just please don't practice in my neighborhood!

Ranger

I'd begin in TC-Off. Then Progress to Everything On, in which the car will give clear feedback if the rears begin to spin. So using both modes will give less or more feed back as your sense of the rear tires improves.

Nor mine. Gotta pick a few good spots where safety is assured.

Then come and play in mine

Post #45 of the FAQ is now the drag racing post. Ranger, and every one else, let me know when you have good info to add to it.

I'm going to the strip tonight and I'm actually much more concerned about my 1-2 shift than my launch. On the street I get tremendous spin on that shift and I know that will hurt my times. I have LGs and a tune.

Ranger

If you're planning to run stock tires, drop the rears to 27-28 before you stage. Drive around the water, not through it. TC-off.

Unless you are comfortable doing a burn-out, trying to heat the tires will only add an additional complication.

Suggest some lift of the 1-2 and 2-3 shift. If the spin is manageable, you can get a bit more aggressive on subsequent passes.

Let us know how it goes.

Thanks for the advise. My stock GTS ran 12.1 @ 118 but spin at the 1-2 shift was always my problem (1.8 60s on stock tires) I actually felt it slow down at the 1-2 until it hooked again. In the back of my mind I keep thinking about the axle I broke a few weeks ago.....

Ranger

In light of that, suggesting lifting the throttle if you sense wheel hop. I've had none on my car so far. But wheel hop is a destructive force if the driver stays on the throttle once it starts. Would also ensure that the launch rpm is not extravagantly (ahould I say dangerously) high.

On stock tires at three tracks I've used 2700-3300 without inducing excessive wheel spin. A desirable launch would include enough spin to cause the revs to climb when hook-up occurs.

And, don't forget to place sitting in the upright position. Move seat as much forward as possible allowing good leg movement w/o hitting knees on the bottom of dash.

By moving the seat up, this will allow you to have good pressure on the pedals and a good grip on the shifter. Remember, the car will throw you back as it accelerates. Implementing this practice along with Ranger's advice, should net you some pretty quick times. Oh, and one more thing, when you heat up your EMT tires, just do a quick spin for about 5 to 6 feet or so... NO crazy burn-out.

Try that!

Ranger

Good points, Myhardtop.

Found my ideal seating position by doing my shifting drills. And now have adopted it for everyday driving to ensure the position feels normal at the track.

Seat back in a full up-right position is generally best because the attitude of the car changes radically on launch...rear squats and the front lifts. Unless the seat is up-right, it gets hard to see the racing groove after launch.
