Adam Kindness Posted February 12, 2002 Share Posted February 12, 2002 Im planning to take my supra (94 J-Spec TT) to Crail's 1/4 mile strip on the 24th, but.... just a few issues... 1st of all, what are the normal terminal speeds... as i hope there not over 120... I still have mine limited Secondly - what time would you expect me to get.... its a std engine, and im a novice supra driver!.... under 14's?

Branners Posted February 12, 2002 Share Posted February 12, 2002 I think you will get under 14s at Crail, most 1/4 mile times there are quicker than Santa Pod where I used to get a 14.0 with my standard car. I now run a 12.9 at 113mph so I dont think you will break the 120mph speed. Let us know what sort of times you get. JB Link to comment Share on other sites More sharing options...
Gareth Davies Posted February 12, 2002 Share Posted February 12, 2002 I only recently noticed the defi VSD Huds do 1/4 mile times too... now every set of traffic lights is a drag strip. Mind you they're off by about the same as the speedo (~7-8%). But it does mean you can pull amazing 1/4 mile times Link to comment Share on other sites More sharing options...

Expect low 14s (maybe high 13s at Crail) at around 100MPH with a stock Supra TT Auto. Launch will be important. WHat method are you going to use.

Adam Kindness Posted February 12, 2002 Author Share Posted February 12, 2002 that'l be why i said.... enlighten me.... im not sure.... whats the best way to get a clean start? Link to comment Share on other sites More sharing options...
Syed Shah Posted February 12, 2002 Share Posted February 12, 2002 Simple: Press bkake down, and press on accelerator gently until rpm is approx 2000. This helps build a bit of boost and will bring down your times. Another thing is to shift manually, as it is quicker than letting it shift for you.

Brian Jackett Posted February 12, 2002 Share Posted February 12, 2002 Just remember that power braking where you hold down the brake while reving the engine, can cause problems to the auto in that it can get to hot and damage it. I have only heard this and have not read this anywhere. But it seems a bad thing to do to any auto, just to get a good time. regards Link to comment Share on other sites More sharing options...
Dipstick Posted February 12, 2002 Share Posted February 12, 2002 I think you will find find that guys in the states that use power braking reqularly have had the tranny fail due to the heat build up in the fluid in the converter whist braking with modded cars. Dont hold it for too long. IMO one or two should not do any harm with a stock car. Link to comment Share on other sites More sharing options...
Adam W Posted February 12, 2002 Share Posted February 12, 2002 From what I've heard on here (no personal experience - I'm not into autos), there's no problem with power-braking if you're sensible. Hold the brakes, rev to ~2000rpm, release brakes. Problems can arise if you hold the car straining against the brakes for more than two or three seconds - all that energy is dissipated into the transmission fluid and it gets very hot. I suppose if you made a habit of doing it, it would be worth halving the time between transmission fluid changes as preventative maintenance, but the odd outing to the drag strip shouldn't cause a problem *from what I've heard*. Someone shout out if I'm wrong! Link to comment Share on other sites More sharing options...
