Is it bad to launch WRX every so often?


Recommended Posts

Hey guys so this is probably going to sound stupid but I "accidently" launched my car today. I was about to turn at an intersection and there was another car that had right of way, so i started rolling very slowly to get moving behind him but he then stopped and was letting me go for some stupid reason. Because of that, I realised I could not just keep rolling forward so I pushed the clutch back in and was gonna stop, but then because I was at an intersection and he was stopping, my mind went GO and so I simultaneously pushed clutch in and engaged the accelerator, putting RPMs to about 4,000 before dropping clutch.

 

As I said, this was all a muddle and happened so fast but I heard any car but WRXs in particular should not be launched.

 

I just had mine tuned to 302 flywheel horsepower so it has a good bit of power running through it.

 

I never launch it, always roll on the power and am very careful about NEVR launching it, so right now I feel a bit worried about the damage.

 

If car is still driving the same and no burnt clutch smell, is the worst I have done accelerate drivetrain wear a bit? Does damage from launches usually happen "instantly" like you blow a gear etc, or could I have legitimately weakened things a lot from 1 or 2 launches?

 

Just feeling dumb right now as I have finally tuned my car, I always make sure to look after it, service it and not abuse it so I get annoyed at myself when I do dumb s*** and also worry since I don't want to be shelling out lots of money for transmission or drivetrain repairs.

Nah bro you're all good, WRX's are tough, a launch or two won't hurt.

 

Haha yeah I just feel dumb as, I hate doing things like that.

 

Just out of curiosity, I am always weary that the trans could go, especially since I have a 200,000km vehicle. What is the best option to fix at a decent price. I don't want to spend 4k on a full STI swap, so do you just buy a used 02 trans? Or is it better to buy a used 03 - 05 trans? Or any other options?

Drive it, enjoy it, worry about the trans when something happens - K's really aren't everything, service history plays a big role.. If it does go pop, just throw in another, or even try find a 5sp STi box with the right ratio to match your rear diff and get back to it.

 

My car has done 147,000k and 4th gear is crunchy, not the end of the world and it still gets a beating when I drive it.

A 4000rpm clutch drop isn't exactly a launch, did it even chirp the tyres?

 

There's at least a few people out there that just use the rev limiter as launch control. Not saying it's good for the car but it doesn't just instantly break it.

4000 rpm, done that many times before especially from hillstars on the old v7 which was extremely free revving with lightened flywheel and unecessarily large throttle body.. it's not much of a problem unless you uphill with bunch of crap in the car and carrying heaps of heavy passengars. how did you manage to measure power at the flywheel after tuning? removed and put it on the engine dyno? normaly tuner gives power from dyno measurement which is at the wheels.
