try it using 2nd gear and dumping the clutch. Or since you drive the car more then your friends father go buy a front line lock for it and have that installed.

 

Turn off the Traction control, or you'll get nothin.

 

I assume you've held the TC/AH button down for 5 seconds until the message "AH and TC off" displays before doing this? It's a lot harder to power brake a car with a manual tranny because it is difficult to modulate just the right amount of brake while operating three pedals at once.

Try dropping the clutch and once it starts spinning, move your left foot over to the brake. IMO, power braking on a car that can easily smoke through 3 gears is a bit ignorant but if you must, get them spinning first and then move over to the brake once the clutch is out. Torque management and other factors could cause it to die if you are riding the brake and the clutch at the same time.

We looked into a line lock but we didn't want to mess with installing one of those. We just like to do the basic bolt ons but the Vette is completely stock right now.

Traction is always turned off because that's the first thing we after we start it up.

 

Now I'm confused. I figured you were power braking to smoke the tires in order to heat them up. You might do that if you have slicks at the track. Is that what you are doing? If so, you ought to be able to get them spinning in the water and move your left foot quickly enough from the clutch to the brake in order to stay there spinning. It sounded like you were on all three pedals at once which might cause some confusion in the torque management.

Other than to heat the tires (probably needless with stock tires), there is no reason to power brake. The best launch for the dragstrip I've found is to rev to about 3k (with traction off) and dump the clutch. On the street this will just generate massive tire smoke, but the strip tends to be a lot stickier.

 

Your right, we tried using all three pedals which is damn near impossible. I figured it was because of the technology of the Tourque Management. We mostly wanted to know how to do it so we wouldn't look like idiots when we take it to the track.

 

Dude, unless your a Pro don't turn off the AH, those 400 horses will get away from you quicker than twinkies in front of a fat man!

 

I wonder what the dad would think of your question? Why don't you ask him how to power brake his 400HP C6 and i bet it would be the last time you drive it.

I had an 02 SS and it was nothing compared to the C6 in regards to brute torque and HP. You'd better be careful trying to do this. It's bad enough that you're beating on someone else car...but if gets away from you and you crash it!!!!

 

Yeah, only turn off AH/TC if you are a dragstrip veteran who knows how to handle that much power. That said, you will get slower times with it on, even when only the AH is on and TC is off. Your best times will be with everything off, at least on the M6 cars. That is, if you can keep it off the guard rails.

When I was 16 years old, I asked my father if I could take his 1984 Vette out for a night on a date. He said I could. Two weeks later, the date came up. That night, he wouldn't let me have the keys. Why?

Because he found pics of me smoking the rear tires! In those days, the cross fire injection with an automatic couldn't do it on its own. My friends and I poured bleach on the street, power braked and lit them up! It was fun, but I don't think I drove that C4 again. :o

20 years later, I'm thinking my kid ain't never touchin' my C6 without me there.......




btw, I still have the pics, but they're on film (not digital)....imagine

 

you don't have to hold it down on the C6's for 5 seconds. Just press it twice and your good.

 

Power braking?

We teach proper braking in High Performance Driving schools.

The term "power braking" is not in our vocabular. Threshold braking is.

Threshold braking is braking hard enough to almost activate ABS.
You brake HARD at first then ease off the brake. Not like most ppl brake easy at first then hard when they realise they might hit something.

However, when you do use ABS it is saving your ARZ.

to give you an idea what this is like, it is like bedding in new brake pads or rotors.

Go find a no traffic straight road. Day time only not at night.

Accelerate the car up to 40 mph, then STOMP, not step but STOMP on the brakes hard enough to ALMOST ACTIVATE ABS. and slow the car to 10 mph. Do this 3 to 5 times one right after an other.

Then accelerate the car up to 80 MPH and do these stops again. 80 mph down to 10 mph. One right after an other.

If you have the nads then 100 mph down to 10 mph.

Rember straight line braking only. This teaches advance braking teaches emergancy braking techneques.

Now here is a catch, if you brake and the rpms drop to a point the car WILL STALL. Any time the clutch is depressed when doing HARD braking the cars engine is still pulling the car foward so it takes longer to brake and stop your car. What do you do??? Put the clutch in and brake at the same time.

DO NOT DOWN SHIFT WHEN DOING HARD BRAKING. Heck never downshift. The brakes are to slow the car down, not a lower gear. Downshifting only hurts the transmission when slowing down quickly.
That is where the practice of heel-n-toe come in. When downshifting the throttle is depressed slighlty to increase or match the engines RMPS with the drive shaft speed. abotu 1500 rpms is needed.

Heel-n-toe is not really useing your heel and toe, but the left side of your right foot is on the brake peddle and the right side of your right foot is ( or the ankle is rolling under ) to quickly depress or blip the thottle to increase the rmps.

The practice of heel-n-toe is an art by itself and Bob Bonderant has written a whole book on the subject.

Be safe out there

 

Wrong. You have to hold it down for 5 seconds to get both AH/TC off. If you don't hold it down for 5 seconds, one or the other (AH or TC) will be on!

Mike

 

Picture please! Need to see smokin' Goodyears.

 

This is discussed in Tech Forum pretty often.

default - is TC/AHS on
push once - TC off, AHS on (full YAW control)
push twice - TC off, AHS competition mode (spirited driving YAW control)
push and hold - TC off, AHS off (b@11z out, be ready for it to get sideways on takeoff and do 180's on mainstreet with smokey burnouts)

Apparently your school doesn't cover the most popular form of racing, drag racing.

 

There are plenty of driving or racing schools around. We have chosen to teach the Grande touring Road Racing style of driving.
