Crazybassist Posted June 20, 2010 Share Posted June 20, 2010 Hi all, Last night was my first time on the drag strip with my supra, and my first time with an auto! Before I prided myself on getting my manual BMW off the line like a rocket, even if it wasn't the quickest up the strip. But last night I kept getting raped cos my starts were so sluggish. Is there a trick to getting an auto off the line? I tried holding it on the brake and getting some revs up but she didn't seem to happy with that. So I then just planted it from nothing and had to wait for the turbos to kick in. By which time the Evo's and Impreza's had gone! The next race is on the 24th of July, and I'm hoping to have a boost controller fitted by then to give me more of a chance, but getting a good start is so important!

ray007 Posted June 20, 2010 Share Posted June 20, 2010 have you tried using the manu mode and then work up the gears? Quote Link to comment Share on other sites More sharing options...
patrikbrunt Posted June 20, 2010 Share Posted June 20, 2010 for a more spirited start from standstill I tend to switch to Manu mode, into L, left foot brake while building up some revs (not for too long) then off the brake and away you go shifting through to 2 then D as necessary too much revs and you will just wheelspin and not enough and you have to wait for boost to come on.

Rob_Mitchell Posted June 20, 2010 Share Posted June 20, 2010 i scream as loud as i can out the window which distracts the person i want to race, then stamp as hard as i can so the kick down lauches the car off the line.... leaving the ford ka for dust Quote Link to comment Share on other sites More sharing options...

At the pod its generaly better because of the sticky track. but at thunder road on an airfield i had a hard time so i just didnt bother so much. Still managed to come out with a high 12 1/4 time though. Your not going to be able to beat an evo or a scooby over the 60ft or 1/8th mile. but by the 1/4 you shuld be realing them in. If the 4wd boys are risking full launches off the line they are going to achive a couple of things. Braking something or beating you by a long way anyway. from what ive seen 4wd cars that launch properly are always running very good power and the supporting driveline mods for it. or they brake something sooner or later Quote Link to comment Share on other sites More sharing options...
RedM Posted June 20, 2010 Share Posted June 20, 2010 Into D with foot on brake. Release handbrake while checking all mirrors. If safe to proceed accelerate briskly to speed limit. Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted June 20, 2010 Share Posted June 20, 2010 Nail it?? Brake boosting as above. Foot on brake, box in D, rev to about 2k then brakes off and nail it. Quote Link to comment Share on other sites More sharing options...

Do brake boosting hurt or damage the auto transmission in the long run? It can boil the transmission fluid if you do it for to long Quote Link to comment Share on other sites More sharing options...
Zofix Posted June 20, 2010 Share Posted June 20, 2010 Ok so if you just keep the trans fluid temp low, you can brake boost as much as you want? Do anybody run a higher stall converter with their stock auto transmission? Quote Link to comment Share on other sites More sharing options...

KamaSupra Posted June 21, 2010 Share Posted June 21, 2010 Do brake boosting hurt or damage the auto transmission in the long run? That's my worry too, my mate who has an auto said it's a bad idea to do it after seeing me do it in my car Quote Link to comment Share on other sites More sharing options...
Guigsy Posted June 21, 2010 Share Posted June 21, 2010 (edited) you dont need to do it for very long. just a few seconds. You get the hang of it after a few runs. And when its at events where they time you from the moment you trigger the timers at the start rather than when the light goes green its not an issue. Just do it when your ready and forget about the green light and being first off the line unless your lucky enough to have a trans cooler fitted or have a uk spec which i think came with one.

Guest Snaps Posted June 21, 2010 Share Posted June 21, 2010 ^ Yep, UK Spec came with both a Tranny cooler and a Diff Cooler Quote Link to comment Share on other sites More sharing options...
Ian C Posted June 21, 2010 Share Posted June 21, 2010 That's my worry too, my mate who has an auto said it's a bad idea to do it after seeing me do it in my car Nah, you can hold it on the brake for a good few seconds without cooking things, if you need more than 5 seconds to get the revs right you probably shouldn't be driving Quote Link to comment Share on other sites More sharing options...
