Wrong section,... also racing talk is not allowed...

I think that only applies to street racing. He didn't specify what type, legal or illegal, so I think most will assume he is talking about a legitimate run at a track...

Anyway - The general strategy for launching our cars is to put it in '3' , turn ETS off, and launch from anywhere between 2 - 3 grand, depends on how sticky your tires are I guess, as well as track conditions...

Not to be rude, but it is racing storied that are not allowed. If I am wrong, my apology then, lol. Answer to the question is leave it in 3 and torque the engine up to about 2000-2500 RPM. Drop tire pressure to around 24 psi. That is just my theory which gets my '00 SE a best time of 15.2 stock. Hope this helps.

Lighten up this is no racing story !!


Anyways some good drag strip tips around here somewhere.. lmk if you can't find them

So you're saying that I should turn my ETS off, lower my tire pressure, and have it in 3? Then, on the launch, have one foot on the brake and lightly press the gas so the car revs to 2500 RPM. When the light turns green, let off the brake and floor it, popping the car back up into drive a quarter of the way down the track or so??? My only two times at the track, I've just had it in drive, and gunned it.

[Kodeblue]

Yes, keep your foot on the brake, apply the accelerator until you reach around 255 RPM. Another thing I do that helps out, is count the yellow lights as they come on, it helps for a good reaction time rather then just waiting until you see the third yellow and going. Do not wait until it is green or you will have a high R/T. You do not need to put in in D half way down the track either, I don't think it would even hit that overdrive gear anyways.

3rd goes to I Beleive is at 90ish MPH so If you have a really good run then you MIGHT need to slip it into D

Not that he will get over 90 MPH stock, not much anyways if he does.

I've had my car to 120 mph in 3rd gear, but it was also on a chassis dyno.

Why would you need any dyno time???:huh:

JOUT

[Schweppe23]

To see if my AC CAI works. Thats Air Conditioned Cold Air Intake gen2 for those that are in the know. Also the hoover hooked up to the tailpipes has given me tons of top end. I may start selling these kits on ebay. They are tons better than electronic superchargers.

But back to the question at hand... 3rd gear rev it up to 2kish ease off brake and gradually into the gas....but do this fast but slow.

.03

[Doug]

Yes you will not run out of gear in third. But you can just leave in drive. Doesn't make a difference. cause if your at WOT it will not shift into OD.

[chill03sct]

dont launch in 1st... its bad to manually shift your auto and taking it straight up to redline that way. stick car in 3rd like said above... hold foot on the brake while giveing pressure onto the gas, launch at about 2500 i would say or wherever your ride seems to take off better from. if your talkin about track racing, go on the third amber light, not green to get a good reaction time when bracket racing. good luck!

[chill03sct]

by the way... what times have people pulled in overdrive and just drive? any significant changes in et's? let me know... i notice difference just seeing where i stand...?

The A/C CAI really works, but now it gets really hot inside of the car. :( Guess you have to sacrifice something for performance.

As far as the Hoover....I used a shop vac instead. It's a little heavier but the gains offset the extra weight. :thumbs:

Just leave it in 3rd and go. I barely hit 3rd by the end of the quarter so putting it in D will have little affect.

[Robznob11]

I don't know about your cars. but leave mine in drive on top end and floor it it will shift to third and stay there untill you let off the gas and it will top out at about 133mph at around 5800rpm where the rev limiter stops it. so I don't know how you guys think you will run out of gear in third. becuas it will pull hard up to 125 or better and you will never see that in the 1/4. just my .02$

I am packing Twin Eureka 5110s. I mounted them in the trunk for greater weight on the rear wheels. Better traction. I gained like 3 HP. I am still trying to find the right place for my Eureka decals b/c that is going to release another 30HP from those suckers!


I launch best at the track in D3, ETS off, 20 lbs psi Nitto DR and feathering off the line. Modulating the throttle to keep the best adhesion I can. It is a tricky game, especially at slick tracks (Mylun). I can usually get the 60' down to 2.2's ... I need more practice and lower psi in my Nittos - like 10lbs! - for a near 2 flat 60' which should give me a much better ET.

[PontiacGT2K]

Lower the psi to around 2psi, you'll get mad phat tract-shun. It sorta hurts you up around 190 mph....but hey our cars wre made for the 1/8mile anyways, you won't usually see 190 in the 1/8. 2 second 60' is all you get? Damn....lower that psi playa, I get 1.5 60' times all ova with lower psi on my mad slick DR's.

[Knappy1]

Don't forget a proper suspension setup for the track. You want the rear end jacked up and stiff, so it can't squat, and you want the front end held low and stiff, so it can't lift. I do this by placing rubber spacers in the rear coils and I have a brace that bolts to the subframe for the front. The brace has set screws in it that push the lower control arms up and keep the front held down low...trust me, your launches will be much better if the weight doesn't transfer to the rear. You can shave nearly 1/2 sec off your E/T with a proper set up and launch.

Oh yeah...and Eureka's BLOW!!! Get the 8lb Oreck Vacuum....

Rob TRU, but I don't have to worry about that. I got the AWD swap kit from ramairtech, and some Skunk2 coilover. It's ridin on railz now...

[chill03sct]

i was gonna say... a 1.5 60ft on slicks alone is awesome, and to accomplish it in a front wheel drive also!!! i knew something was up... anyways by the way notice you live in st charles... used to live in geneva 6 years ago... just thought i would add that in:D

[PACE]

That is correct- 3 or D is the same at the track cuz if your foot is to the floor your car won't go into Overdrive (4th).

[IanGT99]

Well, I had the car out on the road today and punched it a few times...twice on 3 and twice on D. In all honesty, I couldn't really feel a difference except for maybe a little better shifting in 3.

I have found that the ECU will hold gears a bit longer in 3. With RE950 tires I get just the right wheel spin at full pressure. I would mess with it until you get a good amount of traction.

[3400MAN]

So about half are for putting it in 3rd gear and the rest say leave it in drive......hmmm.....How about leave it in drive, rev to 1500-2200 rpms let foot off the break and punch it. WHy do you suppose traction control off is better than on?

[IrateSpeed6]

Way to stay on topic everyone. Thanks Pats and Tom. Some good basic stuff in here, everything else can be found by a search of the forum. :thumbs:
