    Launching

    This may be posted in the wrong forum, but I notice a lot of people hang out here.

    How the heck do you launch these things? I just got a 2010 WRX, put in a short throw, once I'm in gear, takes off quick, but launching? Different story.

    I've tried it twice on my own recently and now have decided to ask the pros. Any ideas?

    Rev up to about 4k RPM, don't dump the clutch, but quickly ride the clutch. in one swift and steady motion let out just a bit faster than riding the piss out of the clutch. if you let out too quick, you will bog the car down and ***k up your clutch. if you do it too slow, you will burn up your clutch and smoke the piss out of it. basically, just a bit slower than dumping it. be ready, becase as soon as the clutch is finally all the way out, it will be time to go to your next gear.

    you can start practicing your launches at about 3k if you wanna be safe...trust me these clutches get fried easily! let out the clutch right the point that it catches and hold it. then put the pedal down to your desired rpm. when you launch, let out the clutch (it will take time to find the right speed to let it out.) and right as the clutch is fully gripping, floor it. then be prepared to shift as soon as you take off. dont worry, launching an awd vehicle is not easy...unless you have a monster tranny and can just dump the clutch like my old man with his Porsche!

    i would not listen to the advice just given to you...the way to launch the wrx requires a lot of trial and error and chances are you will damage your car a lot trying to perfect it...rev it to 5000 to 5500 and on an up blip, slip the clutch out...too slow and you will burn your clutch, too fast and you will put the shock load all on the trans....there is a way to get it "right" and not do either, but this takes a lot of practice which i wish i never learned ...i can cut consistent 1.7's at this point, at the cost of the stock clutch and a lot of damage to the trans....good luck

    Thanks everyone. I appreciate all the advice. Yes, I know launching isn't advised, but it really isn't good for any car. Just watch one professional drag race and they go through the whole rebuilding process between each race. (Of course they've got the money, tools, parts and know how.) I've just never had a car that is difficult to even take off quick from a stop light- I NEVER RACE, but sometimes you have to get around someone to make a turn or something. There is also some crazy freeway onramps around Los Angeles that require a quick start.
    And I'll try to launch a friend's car as much as possible first.

    With a stock tranny no way in hell would I rev to 5K+ and launch. That is just asking to grenade your tranny.

    I have a stock 5-speed tranny pushing 320whp/294ft-lbs. I still have the original tranny and my stock/original clutch with over 80K miles on it.

    It takes LOTs of practice to launch correctly. Personally, I launch b/t 3000-3500 rpms and slip the clutch. The key is not to bang the gear and time your clutch engagement (full engagement with the shift) and let it go of the clutch smoothly (slip it nicely). It is much better to be smooth and precise than too quick and harsh/banging gears.

    It will take practice and once you get the hang of slipping the clutch correctly it will become 2nd nature. Then you can move on to learning how to "heal n toe."

    Attention Moderators!!!
    Wake up and smell the coffee will ya!

    Here is what we need. We need a sticky post put up in the "Motorsports Sticky" section. It needs to be a 'how to' type of thing. It should be really simple and easy to find. Something like "Launching techniques. ***READ ME FIRST!!!***" or something like that. That way, when we have new members, they can go to that post and see the experience from all of the seasoned veterans, and even professional drag racers launching WRX's with different mods and platforms and what works in each situation. We are talking posts from almost a decade ago. Now THAT would be cool. That way we don't get the same question asked every two weeks for the rest of my life.
    Thanks!

    Even if a sticky was made it would be glanced over and missed like every other sticky on this forum.
