ITT - Wicked AWD launches!!!

Be very careful launching your WRX, the 5 speed can't take the abuse. Otherwise, yes, when we say "launched at 4000 RPM" usually we have launch control set to 4000 RPM or we let the clutch out (in one smooth stroke, not a dump, and not a sidestep) at 4000 RPM. Enjoy the car, especially at such a young age. I didn't get my STi until I was 22

Dude it's 1.6. Achievable for even a relatively stock, healthy IRS C4 Y-Body with a good driver and soft rubber. Mine was a 6 speed with LSD. On drag radials in dry it would roll just about anything from a stop light. 375 ft lbs at what may as well be idle. Check out what other C4s typically get, before butchering the car up for a straight axle:

How about 1.28 on the stock Dana 44 IRS (Usually those rears give out after a few passes at 1.3x)

The point is if traction is abundant there's no real advantage to AWD for launching. All your weight goes to the rear anyway. The fastest launches are done with giant tires and RWD. Not to mention the added stress on components from all wheel drive launches - what's cheaper/easier to replace: rear tires or a clutch? IIRC the electronics on the new evos and stuff transfer all the torque to the back in launch mode on tarmac settings - goes to show imho.

You're missing the point. Those are all one trick ponies that aren't street legal as is, and are going to suck ass at the first corner you come across.

I'm talking about cars that hit 1.6 or better on street tires and can still be legally daily driven and entertaining on something other than a dragstrip.

Don't you mean "no other pedophile in the US"?

I heard you had the fastest free candy rape van in the country...

1.6 or better, yes. For a car on street tires that can repeat that time on the street or on the strip, that's not bad. See my response above for Koll. I'm not talking about dedicated drag cars.

Launching a car puts stress on it no matter what wheels are driven. In that post you just linked, almost everyone is complaining about shit breaking.

Verrückt I thought you had an R8. you got an S4 now? if you have both... :envy:

I've sidestepped the clutch off my 4300rpm 2-step on an 02 WRX tranny and nothing's exploded yet. Shit, at 4000rpm if you dump it it'll probably bog.

I know quite a few 8 and 9 sec cars (with WAYY better than 1.6) that are street legal and yes, do drive on the street.

That's great, but I don't care. Do those cars handle worth a damn in that trim? No. Are they useable in the rain or snow? No. Do they make good daily drivers? No.

This thread is about AWD cars that offer respectable acceleration, good handling, and can still be daily driven despite 500+ hp. It's got performance you can use all the time.

If you want to make a thread about dedicated drag cars that do one thing well, go right ahead, but this isn't it.

Do not try this at home.

I've seen tons of WRX/Evo videos on youtube!

I had no idea it was that easy to get a 1.6 learn something new every day

If you do an AWD launch right, you don't burn clutch at all. The point is to spin your tires instead of burning clutch. If you burnt clutch launching an awd car, you're doing it wrong.

Nissan's ATTEST-A transfers torque to the front wheels on a launch, Audi S4 actually has front wheelspin problems with launches, and the Evo's and STi's AWD system transfers torque based on yaw, not pitch of the car

I think the only "AWD" car that transfers torque rear on a launch is the Volvo Haldex systems, which are normally FWD and transfer torque to the rear on wheelspin
