AWD launch evo IX
Well, I took out what I thought was a stock clutch and found a Exedy clutch with a ACT light weight flywheel.... Good stuff but I still put a ACT 6 puck in anyway. I'm now running a FP Black (ball bearing), Kelford 272 Cams, Beehive valve springs w/titanium retainers, ARP head studs, 1000cc injectors, Walbro 255, Full exhaust w/cat delete, O2 housing, Grimspeed 3port, upper and lower I.C. piping, Large front mount I.C., upper and lower AMS clutch lines, clutch pill removal, and custom intake. Waiting for my 4 bar Omni sensor since I only made 405whp 333Tq. I was really hoping for 430+whp at 360+Tq but well see after the map sensor gets here. The sensor wont make more power but it will help tune by the ecu looking at the boost instead of load. I'm running 27psi but in 5th it tries to go to 33psi 8(

I don't what else you would call it or what other purpose it would hold besides helping you launch the car better.
I took a buddy out for a ride the other night and he couldn't believe how quickly and firmly the stock clutch grabbed. I'm only at 330 whp/ 320tq but it's a very solid OEM clutch IMO. I don't know if that's helpful to anyone, lol. Thanks for the explanation on the first page, I'll have to give that a shot. I haven't launched the car yet, just lots of spirited driving to this point...
It is a form of launch control I would say. It cuts fuel and allows the car to build boost while stationary using a secondary rev limit that only works while the car is stationary.

1. He didn't say he was street racing.
2. You don't need to remove the pill or adjust your clutch pedal. Those MAY help the clutch feel, but they won't help you logically launch the car.
3. Stock Evo clutches are anything but weak. They do exactly what they were designed to do.
With the car stopped, and in first gear with the clutch pedal depressed, you need to SLOWLY build the revs until you hit the 2 step at 5000RPM. Once you hit that 5000 RPM 2 step, then you should fully depress the gas pedal.
At this point, you're still stopped and the vehicle is bouncing off the 2 step at 5000 RPM. Keeping the gas pedal floored, you need to lift the clutch out slightly (just enough to get the car to inch) this is taking the slack out of the driveline. Once the car starts to move forward, you can begin to release the clutch pedal appropriately.
You either want the tires to spin (which is unlikely at 5k on a stock Evo with good tires) or you want the clutch to slip a bit. THIS IS WHAT IS SAVING YOUR DRIVETRAIN. As the springs in the clutch compress from the added load, you will feel the car surge forward until the clutch pedal is fully released.
This all happens very fast, but it realistically needs to be a calculated maneuver. The gas pedal should remain floored for the entire process until you need to shift (unless you have a no lift to shift setup).
