Post Tips to launch

I am noticing that when Im at a light or w/e and I go to take off quickly there is a period of time that the car lags a bit until RPMs get up. What is the best way to launch? What RPM before releasing the clutch or any other tips for a quick start. Thanks for all of you who have given positive suggestions and comments! Almost everyone has been super nice on this site You guys rock!

I wonder if he is speaking more about just basic, daily driving.

To OP: If you are talking about launching, as in getting a high-performance start, I concur with searching the Motorsport section.

If, however, you're simply speaking about daily driving, I think you're question could be answered here. The EVO is a heavy car, and because it's a 2.0l turbo, it doesn't start hitting good power until the turbo has started to spool. If you drive it like a lighter, N/A car, it will probably lack the torque you need and start bogging down. Regardless, there is still plenty of power to get the car rolling under normal circumstances, so if you are bogging down at the start, your RPMs probably aren't as high as they should be as your engaging the clutch.

I've personally found 2-2.5k rpm at launch to be pretty good for daily driving. Once the car gets moving, maintaining ~2k rpm should give you more than ample throttle response to continue either accelerating or cruising. Anything North of a 3k rpm launch is unnecessary in everyday driving (IMO), and should probably be addressed in the Motorsport section.

^ That's about what I do for my "normal" driving. Coming from 2.0L WRX and a 2.5L WRX, I've found that the Evo 10 lacks a bit of that low end to (what I call) lazy roll accelerate. (Subarus are also known for their long progressive and conservative clutches that go make it easy to modulate). For a faster "normal" launch, I let it get to about 3k, slip the clutch out then get the rpms to around 4 and then modulate until I feel that bite.

Done right, there's not much of a burn at all, and gets the car off pretty strong. I'm at 20k miles, been Cobb Stage I since 1k miles, and the clutch feels like new still. Every once in a while when I do a full out hard launch I get it around 5k but that's another story reserved for the motorsports section..
