Default Z06 Launch Techniques

With racing season upon us, I was asked to repost this article on launch techniques that I compiled from my previous posts in 2001-2003.

Hope it helps some new racers improve their times safely and without breakage to their cars.

Ranger

+++++++++++++++++++++++++

Some Basics

Here's a quote from a 2001 post by the Bowerboy, a famous Corvette drag racer.

With an old/stock clutch your options are limited. You will have to hold your RPM's below 3K and slip it slightly. If you had an upgraded clutch (not stock or Z06) I would recommend launching at 3500 to 4000RPM with a slight slip. The type of Tire you will use will also drive your launch.

If you are running stock tires, keep your launch below 2500 RPM regardless of clutch type. If you are running a drag radial, make sure you sufficiently heat them with a burnout before staging. Either way make sure your stage shallow.

The following is a description of staging shallow: The are 2 yellow lights which indicate the staging area. They are separated by 7 inches. When the track worker waves you up you approach the lights and as your car rolls you will turn on the top light first (pre-stage). As soon as the first light goes on, stop. Then slowly nudge your car forward until the second light goes on (staged). Stop immediately! When you launch your car, the clock does not start until you break the beam of both the pre-stage and stage lights (the starting line).

As soon as both lanes are staged (The staged light in each lane is lit), the first of three large yellow lights will light. On the third yellow light begin your launch. With a shallow stage. your car will have a few inches to begin rolling before the stage lights are triggered indicating you official start.

Once under way, quick shifts improve ET and MPH. Be sure to max out your RPMs without hitting the rev limiter. I shift at red-line minus 300 rpm. On your 1st to 2nd shift, power shifting (leaving your foot on the gas to the flow as you depress the clutch and make your shift) is not recommended do to traction. The 2nd to 3rd shift can realize a significant gains with a power shift however, this is the trickiest to maneuver (directional angle of the path between 2 and 3). The 3rd to 4th shift is the easiest to power shift.

Here's a link that provides some useful info:

NHRA Drag Racing Basics


"Ideal Launch RPM" defined by the Corvette Program Office

First an optimum launch rpm must be established which is a function of ambient temperature, sun load, track surface, tire temperature, vehicle loading .... An optimum launch will allow enough wheel spin so that when the tires "hook up" to the pavement there is not a loss in vehicle acceleration."


Launching a Z06 on Stock Tires

Here is what I do. No claim it's the best way.

Competition mode. AC and audio system off. Windows up. Tire pressure 44-48 psi (front); 24-28 psi (rear).

Try 2800 rpm. Increase or decrease the rpm 200-300 each run until you find the sweet spot for your conditions.

Engage the clutch over the first 2 to 10 feet of movement depending on conditions. Go WOT ONLY once the tires are hooked, and do so by squeezing the pedal progressively to the floor.

If you do some practice on old blacktop and ambient outside temp is around 75, you ought to be able to launch leaving only about 10 feet of rubber.

Another key is on the 1st-2d shift. Ease the throttle just enough to avoid a lot of wheel spin, which will hurt your time. When I began drag racing the Z06, I shifted to 2d at an indicated 6200, 3d at 6300-6400 and 4th at 6400. Objective is to shift as high as you can without hitting the rev-limiter.

What you are after is developing the launch "touch" combining input from all yours senses. I can feel the tires spin in the steering wheel, clutch pedal, and seat of the pant. Sight and sound help too. But the F1SC tires don't make much of a squeal when they spin.

I use Competition mode rather than "AH/TC off" because I want AH to intervene should the rear get substantially out of line. Just some insurance to limits "the worst that can happen."

Two last things you probably already know. Be sure your oil is above 155 degrees (preferably above 170) before you do launch practice. Also choose your spot wisely.


Why I ALWAYS Run in "Competitive Driving" Mode

I posted this in Feb 2002

I've alway run in COMPETITIVE DRIVING mode at the drags. Do it on principle...It has no effect whatsoever on my times unless my rear end gets seriously out of line, at which point active handling will be invoked, thereby saving my a $ $. In such a moment, my ET would be the last thing on my mind.

Today I narrowly averted a disaster that was not of my making. AH saved my butt and vindicated my practice of running with it turned on.

I made eight passes at Capitol Raceway in Crofton Maryland. On the fourth pass, I was next in line behind a highly modified car that spewed tranny fluid on the track just after the 60_ mark. Unfortunately, no one, including me, noticed the spill as it occurred. AND, I was next.... I had my best launch of the day (1.82) and slammed 2d gear hard amidst his tranny fluid...whereupon my rear end moved violently right...toward the wall. Fortunately, Active Handling engaged and queued me to back out of the throttle immediately upon recognizing my predicament...but not before I had come within just a foot or so of the wall.

Had I turned AH off (as many people do), I surely would have hit the wall HARD. Wouldn_t have been my fault; but certainly would have spoiled the day. When that occurred, the last thing on my mind was my ET...which was a 12.81...in a day of 12.04 and a bunch of 12.1Xs, plus one trap of 118.1...all in COMPETITVE DRIVING mode.

Here is the full thread. Toward the end is a hair raising story that turned out BAD and underscores the need to keep AH ON at the drags. COMPETITIVE DRIVING Mode at the Drags--Disaster Avoided

Another post about my "wall incident":

The "queue" from AH means that within fractions of a second (literally) (1) my rear end moved violently right toward the wall and (2) AH immediately invoked counterveiling action. Both produced sensory inputs that deviated from the norm and I backed out of the throttle. The car came straight again nearly against the wall. It had moved right about 12 feet. Total time of the event was around half a second.

I also made some steering correction, but AH played two roles (1) its pulsing actions queued my senses and (2) it took psoitive counterveiling action to correct the out-of-line condition. Given that AH makes corrective adjustments many times in a tenth of a second, it certainly was the dominant factor in my staying off the wall. True, I backed off the throttle, but not until the accumulating sensory inputs caused me to recognize my predicament; but in those crucial tenths of a second AH had already been in action.

Lota folks can recover from just "loose." But few (without AH ON) can recover successfully from "violently loose." You may be one who can, I'm not.



Burn-out of BFG Drag-radials without a line-lock

Here is what I'm doing; no claim it's the best way.

Back into the waterbox if possible and immediately spin the tires just enough to get a full rotation of them, but NOT enough to throw (much) water up into the wheel wells.

Roll forward out of the water few feet; but do NOT roll so far as to put the rear wheels onto the rubber/VHT prepped area.

Make sure you're in COMPETITIVE DRIVING mode. Put the 6-speed in 2d gear.

Drop the clutch and feed the throttle and (if necessary), quickly lightly apply the brakes with your left foot. I donÕt usually need the brakes but some folks find it helpful for keeping the rear end from walking sideways.

Bring the rpm to about 6000 until the tires smoke strongly and start to grab and the rpm starts falling. At that point, back out of the throttle and (if applied) release the brake, and you'll roar forward. The tires are heated. I don't count seconds but just spin them strongly until they grab hard.

Takes a little practice. But remember, if you botch the burn-out, DON'T retry it with dry tires. Doing that will likely glaze the clutch...or worse.


Launch on BFG Drag Radials

I hold the launch rpm (usually starting with 3600-3900 on an average prepped track) and then quickly but smoothly releasing the clutch with a full engage occurring over the first 4-10' of movement. I try not to feed it more throttle until I think the tires are hooked. There is a delicate balance to find. But it entails squeezing the throttle progressively to the floor between 10-25 foot off the lights. Drag radials will take throttle more quickly than stock tires, but it's still a "squeezing" action rather that a "stomp." Another big advantage of DRs is that they do a great job holding the shifts to 2d, 3d, and 4th without spinning (much). Most of my sub-12 runs have comes when the shift to 2d little wheel-spin and the car feels as though it jumps forward on that shift. Ditto the shift to 3d.


Burn-out of Stock Tires

After you have accumulated 30+ passes and have started to produce consistent 60' and ETs, you will want to find a way to improve. Here is one way....

If you are running the stock Z06 tires (GY F1SCs), a full burnout will lower your 60' times, all other things being equal.

Avoid driving THROUGH the water. Instead drive around the water and back up until the rear tires are just into the damp area. I then do a full burnout just like on DRs. I don't have a line lock and here is my procedure (no claim it's the best way):

Back into the damp area forward of the waterbox.

Make sure you're in COMPETITIVE DRIVING mode. Put the tranny in 2d.

Drop the clutch and feed the throttle and (if necessary), quickly lightly apply the brakes with your left foot. I don't usually need the brakes but some folks find it helpful for keeping the rear end from walking to far sideways.

Bring the rpm to about 6000 until the tires smoke strongly. At that point, back out of the throttle and (if applied) release the brake, and you'll roar forward. The tires are heated. I don't count seconds but just spin them strongly until they smoke hard.

Takes a little practice. But remember, if you botch the burn-out, DON'T retry it with dry tires. Doing that will likely glaze the clutch...or worse.

Using this procedure, I'm usually getting high 1.7s or low 1.8s on stock tires. That is about a tenth improvement compared to what I was getting with a simple clean-up spin before staging. The burnout also helps to better hook the shifts to 2d and 3d.


A 1.78 60' on Stock Tires

Posted in Nov 2003

First, I only have 16 runs on the 02 Z wearing stock tires. 11 last year and 5 this. After the burn-out (to the point of very good smoke), I brought the launch rpm down to 3100 and got the clutch out fast. Not a pop or a dump or a side-step. Just a quick release in the first few feet. Then, and only then did I begin to squeeze the accelerator to the floor over the next 20 feet of so. Minimizing wheel spin. Perhaps this won't work for everyone. But the principle is the same. Find the right launch rpm and get the clutch out fast and then squeese the throttle to the floor, but avoiding significant wheel spin.

I should add that heating the stock tires also helps to hook better the shifts to 2d and 3d. As for my "slowing down" the shifts on the 11.81 run...I was just less aggressive in banging the shifter and gave slightly more lift to the throttle during the shifts. I shift very fast but am doing some lift during the shift to 2d and 3d. I sometimes powershift to 4th, but only did that on the 11.81 run on Saturday.

As for shift points, I don't watch the tac in 1st or 2d, because things are happening so fast, but go by sound and feel instead. I try to shift at the highest rpm possible without kissing the rev-limiter. I estimate that on good runs I am completing the shift to 2d and 3d at 6500. I have pretty good leg-speed and that helps quite a bit. I do watch the tac as the engine winds through third gear and I make the shift to 4th at an indicated 6500. My 125 runs in 2002 taught me that "just kissing" the limiter wastes less than a tenth, but banging into the limiter "hard" basically kills the run. And that only happens when it surprises you, which means you lost focus and had already left "the zone."

Once I heated the stock tires, I launched as though they were drag radials, same clutch release (fast) but at almost exactly 1000 rpms lower. My launch was at 3100 rpms. Had I been on DRs, I'd have been launching at 4000-4100 in those conditions.


On Powershifting

I don't recommend powershifting until you accumulate a lot of passes. Up to that point, there are plently of things to work on to reduce your ET without incurring the risks to your tranny that powershifting entails. Once you've wrung all the time-wastage out of your passes, then powershifting may me necessary to reduce your times further. But I'm not yet at that point except in unusual conditions.....


How I learned to Drag Race

Posted in Nov 2003; The short version is...

The first car that I owned was a 68 Corvette 427 L71 435hp and did some street racing. Hated to lose and alway wore street tires.

So to survive the street battles against the 406/427 Fords and 426 street hemis, had to learn to drive. That meant getting my traction-limited Vette hooked and keeping it hooked through the shifts.

When I began drag racing in 2001 after I brought the 01 Z06, found that the lessons learned years ago came back quickly and my first pass in the Z06 was 12.54. Since then my times have dropped as I have accumulated more passes and kept the principles in mind.

Plus, I practice shifting alot, alot, alot...usually with the engine off, to save wear-and-tear.

Have also learned a lot by reading this and the other forum.

Finally, I keep a log (spreadsheet) of every pass, every split within the pass, and calculate the incremental times between the splits. This has helped me figure out where I am wasting time and then take remedial action.

Many of us aspire to achieve similar results. I'm buying a helmet and plan on making a few trips to our local track (Gateway International Raceway) near St Louis over the summer. I'll use your mentoring as my guide.

Cheers

I recently moved to St. Louis (Wentzville to be exact) and hope to get to Gateway soon for some fun - let me know when you plan to go!

Ranger gives sound advise - IMHO.

Hey Les. Long time. I spent my first 10 years in Kirkwood.

Great approach for guys pursuing improvment is to hook up at the track with an experience racer like Z06Les. Watch each others' runs, share slips and discuss what happened and why. Great way to learn and better than 20 passes of self-coaching.

Have fun and let us know how it goes.

Hey Ranger,

Yea, it has been a lng time - I have been busy with the move and a new job, so not on the forum as much. I need to get to the track soon, and always happy/enjoy helping others with their techniques - so if you guys want to meet up just say the word ... I am told the Gateway track is OK but WAY busy .. so we should get there early and make some passes before it gets crazy.

Thanks, Matt.

You raise an interesting point.

I just had my clutch changed, preparing the car for a new owner. My clutch had about 150 passes (and burnouts) with launches at 2800-3400 rpm on stock tires and 3800-5200 on drag radials. The old clutch had no signs of failure and was not "sticking." Wear on the rotating surfaces was very even. We estimated the clutch had another 50 passes left in it. But we changed it anyway.

How many hard launches you get out of a clutch depends on how much slip you do. A lot of slip on the launch produces more wear on the mating surfaces. I use a fast clutch release, which is gentler on the mating surfaces.

I also follow a rigorous regime of changing out the fluid in the master cylinder (clutch fluid reservoir). I empty and refill it weekly and again before and after a day at the track. I never allow the fluid to take on color; I keep it clear. This practice has helped keep my pedal acting normally.

Good luck with your car.

Hey John, I looked at my fluid the other day & it's black!
There seemed to be a little sludge around the rim of the reservior as well...How can you change the fluid w/o taking everything apart??

Suck it out with a turkey baster, clean the reservoir, and then refill it. I use the genuine GM fluid from the dealer.

Hey Ron,

Regarding the black clutch fluid...The Syringe for changing clutch fluid in the master cylinder ...I'd suggest changing the fluid every few days until it remains clear and then before and after each time to the track and again every time it start to look cloudy.

I'd suggest using any Dot-3 brake fluid. Following this regime, it gets changed often enough that using a higher temp fluid isn't necessary. Plus the Dot-4s I've tried have leached to black almost immediately.

MAN, i tried these technique on my sticky RII Nittos and had 0 luck hooking up at the track and had horrible 60 ft times. Just need more seat time and find that sweet spot between letting out clutch and applying throttle, etc. Practice makes perfect but looks like i am more inclined to road race this bad boy than drag race it regularly!!

Morer great advise from Ranger. I do (did) the same thing and it seemed to help keep the action smooth. I printed the original post and read it at the track in the lanes. Great advise! Be careful, it is adicting, and can be very humbling too. 1.7x on EOM SC tires
Thanks again Ranger!
