Default 2002 WRX--1/4 mile

Question: what is the best way to get out of the hole in the 1/4 mile. I just ran a 14.7sec with a 1.2 reaction time (I know I need help, but it was my first time) when dumping at 4000rpm, I know that I can do better. I dont want to have to dump at 4000, it cant be good for the car. What is the best technique and what precautions should I take.

Never done a 1\4 and never plan on it. I really dont care how fast my car can do a 1\4 mile in. What they need is a big 1 mile circle track. Id be all over that. Or what Id really like to see for all you GT3 players is that one part on Complex String that has the expanding curves.

reaction time has nothin to do with 1/4 mile time btw.. reaction time is the time light turns green until you pass the first laser at the start.. the 1/4 time is measured from first laser at start to last laser at finish. The best way to get your 1/4's down is to get your 60 ft times down. As for doing that, lighten your car, and practice practice practice. Eventually youll feel the car with the constant strong pull instead of that lugging feeling at the start when you dont put enough gas and drop the clutch at the same time.

try revving way up by redline, dropping the clutch, then as soon as you feel the forward momentum (almost immediately) push the clutch back in about 1/2 way and slip it back out. practice it till you do it smoothly, without lugging the engine. this way you get that off the line jump of a clutch drop, but you dont lug down like a clutch drop.

Dont do that.... ever.

Dont ever launch at or near redline. No need for this at all. Your goal is to stay above 4k, but nowhere near 7k.

I dont understand where you came up with this method, but it sounds like the most distructive way to launch I have ever heard of.

You need to drag the clutch out around 5k. Depending on your mods your technique will vary.

Whatever you do, dont do what he said

This thread probably shouldn't be in this forum but oh well Definitely DON'T do what jasona said!

The best way is to just rev it up to at least to the 4k rpm mark and hold it there until you're ready to go. Then begin to slip the clutch out just enough to get the car moving forward. Once it is beginning to roll let it all the way out. This might sound difficult but it'll become second hand after a while.

Just practice it at the track (the street or a parking lot is too grippy IMO for the trans). Other than that, shift near or at redline and you'll get it.

i "came up with this method" by getting 1.9 and 2.0 60 ft times in a stock 2.5 liter impreza, repeatedly, for more than 33,000 miles and no mechanical problems. im sorry if you dont understand the reasoning behind staying near redline, but there is more power up there than down low.

Maybe on an RS, but in a WRX you don't need to launch that high. in fact, if you launch on boost at redline, you'll just light the tires up big time. The WRX is a totally different beast.

I agree, DON'T follow those instructions.

For me, I just hold it at 3K, floor it on the first yellow, and then drop it on the tail end of the 2nd yellow which puts you at about 5Krpms and 10psi of boost. 1.83 60's everytime. Nathan and Phil do the same thing, but they slip it while flooring it. They bust 1.6 60's, but then again they are making MAD power.

That's my favorite course. That will tell you BAR NONE which car is better. The WRX has too much understeer to do good on those long decreasing radius sweepers.

Speed is sweet. Love it. And I want to learn how to drop the cluch in just the right way so as to get a great launch and still keep the car functional for more than 5,000 miles. However I still feel that the WRX was not built for the 1/4 mile. This car was built for speed in the curves. And that is what driving is all about to me. The fun in driving is speed and acceleration. But I think speed and acceleration are all the much better when you are doing it in a tight turn.

I haven't tried this in particular but I've heard that throwing the car briefly in reverse before launching allows for a better pull off the line.

You can't just make a comment like that and not explain it.

Default Angus is aware of the history of these threads

Do a search on launch and see where 90% of those threads go. Then it will be perfectly clear what Angus was commenting on.

Larry

You might also want to look at the discussion in " Poll: Who wants a forum for 1/4 mile?" on the Factory Forced Induction forum which lead directly to the creation of this forum for the express purpose of discussing 1/4 mile related issues like lauch technique.

Just to update, I cut several 1.81 60's tonight with the above tecnique. Just make sure you in the 5's (5K rpms, but below 6K) and on boost. This is on stock tires btw.
