Hold the revs at like 3-4,000, then floor it, and immediately after (but after nonetheless) you start flooring it, dump the clutch. When the engine is revving up, rather than stationary at a set RPM, it has some resistance so it can build a bit higher pressure internally, then you'll get maximum power once the clutch is engaged. But, of course... this puts a ton of stress on your drivetrain. Things can break!
I understand doing it when you're initially applying throttle, but I'm a bit surprised at your methodology. Most of the people I've talked to who've launched an AWD car (including myself), tend to slip the clutch slightly before (just enough to where it barely touches), then release the clutch; the thought being that there's slack in the drivetrain (to some degree) when the car is stationary, and as a result this causes a shock load to be induced, versus that slack being taken up before the vast majority of torque is transferred. I'm positive you can work out the physics here better than me, but I know it leads to a lot less broken drivetrain components (albeit with more wear on the clutch, but clutches are cheaper than transmissions). This is the technique used on many of the higher power Subarus to prevent catastrophic failure at extreme power levels, and I've seen some stock transmissions hold up pretty well using it (mine included, fingers crossed). Thanks for the response, let me know your thoughts!
Marcus Deemer This was an acceleration/launch vid, homie. You don't double-clutch in a drag/0-60 run, you mostly use it to rev-match when downshifting. I understand Vin Diesel can get to ya sometimes, though. GG.
+Jerry Hu I was jk.. But yes Also because it's Manuel.. Mitsubishis twin clutch automatic transmission delivers perfect shifts.. I'm a huge sti fan, no hater here
He's getting the time off the accesport and the accessport starts timing as soon as you accelerate so when your two stepping your killing time so it's best to rev and let go slow, then two step and skid out of there
These 0 to 60 times are pretty embarassing for an sti, which is one of the reasons the older ones are so much better. My bones stock 2011 wrx will get 5 seconds to 5.3 all day and that is 100% stock. Stage 2 and i am in the high 4's easily.
