Motul. You can either use 90PA which is like OEM but a little better. Or the fully ester synthetic Gear Comp 75W140 which alot of rally cars use in Europe. Its not cheap but I prefer it. Amsoil is also good.

Edit: here's where I buy all my Motul products. http://www.motorspotstore.com/gearcomp75w140.html

 

You can use the e brake method or just make sure to slip the clutch enough off the line at part throttle. Either way will pre load the driveline without shocking it. You just can't let the clutch suddenly grab at full throttle. Kind of like creeping out from a normal stop light at part throttle just enough to feel the car start to roll and then slip as neccessary to avoid the bog, which for me is just enough to get the boost up.

The best way to come out is on a hand brake, but you have to be careful not to creep through it or bog and for me I always screw it up.

 

I heard the hand brakes messes with the ACD on a evo 9.

 

Well this wouldn't matter because you aren't moving while using it. My buddy uses this method on an ACD, but it is an evo 8. I am not sure if there is a difference, but that wouldn't make since that the e brake would effect the ACD at a standstill since the ACD is doing nothing until you move.

 

Good luck hopefully you hit 10's so dumping the clutch is really that bad.

 

The handbrake method is tricky on the ACD evos. If you pull it too much it will disengage the diff and basically make it fwd. If you try launching like that is spells disaster.

To help with driveline shock. This is what I have learned and works. When the second yellow light comes on barely let the clutch out where you can just feel it start to grab. By the time the tree engages let it out and this will basically take the driveline shock away.

 

Good advise. I'll have to try this. Best I could get out of my 5800 2 step is an embarassing 1.9 60'.

 

I agree 100%

I suggest that customers start off on lower boost and try a few easy launches and then work their way up in boost and gradually get used to it

Learning to lauch a high whp awd car without braking parts is a skill that anyone can learn it just takes a bit of practice and trial and error

Also - it is important to remember that the drag track is a lot more stickey than a public road so when you practice on a street its a lot more grippy on the track

For most people I would suggest avoiding the hand brake system till you master the art of feathering the clutch to ease the load on the gear and then progressivly applying more pressure as you begin to roll

I see the stock 03 diff with Turbotrix LSD insert worked pretty good for you too. Must be the guy who installed it.

How many guys have done it on Evo IX's, I heard the Evo 8 transfercase are stronger than the 9's.

 

Paul Nelson ran 9's last year on the ACD t-case.

I think i just need to fly down there and show Steve how to drive his $200k car

I really fell like the ACD system is very strong. I abused it every which way to sunday with no carnage to the thing. I know ive never dumped my clutch and always had Stock Struts at the time so maybe that helped. Also had stiffer bushing in the mustache bar???

 

I told him to go out on the rain and get more practice to launch that b!tch.
