So my old car was a little front wheel drive vehicle with a little extra naturally aspirated (~1:10 hp:weight) horse power. I found that at about 30 mph in second, I could rev to about 6k, dump the clutch and my tires would unlock.

I did the same thing in my evo earlier today to see what would happen and all I got was a the thick smell of burnt clutch. The other interesting thing that I noticed was that there was a good second and a half of clutch slipage before it finally grabbed firmly. I guess my first question is, why was the result of dumping the clutch so different? Is this all due to the evo being RWD (in tarmac mode)?

My second question is that I bought the evo with minor modifications -- as far as I know exhaust, and intake work was done. I know very little about turbos, but it feels like I'm actually producing the most horse power between 3.5k and 4.5k rpms. That's also the point at which it sounds like the turbo is spooling the hardest. Could that be right? If there were modifications done to my vehicle, is there a scientific, cheap way for me to figure out where the power is produced (besides a dyno?)

 

Oh dear.... lol

It is still a 50/50 lock in tarmac mode.

You never dump the clutch.

Your turbo hits full boost @ 3.5k that is peak tq not hp, peak hp is ~6.2-6.5k stock cams.

Launching: Clutch in, rev slowly to 5k then depress the pedal 100% to activate launch control, lift the clutch pedal until you feel it start to grab to remove drive-train slack (with or without holding ebrake), then quickly but gradually let the clutch go. wah-lah nasty perfect launch.

 

you can't double clutch like you could in a honda... that's what you used to do...

the guy above has teh launch down perfect... i cut 1.56 on a stock clutch...

 

also to check the power... i think you can use the virtual dyno using evoscan..

 

Well the evo is not RWD ever its AWD. Tarmac mode just lets the clutch in the tcase slip less compared to when you but it in gravel or snow mode. And I wouldnt recommend dumping the clutch at 6k at 30mph, youll destroy the clutch. As for your second ?, when are you making full boost at? Bc that should be full boost in that rpm range. And you wont know you power curve unless you have it put on a dyno. I know some places by me have dyno days and for like 50 bucks you can get 2-3 pulls with a print out of what you did

 

and fyi your revving to 5k to hit your two step...which yours should be set at unless its been changed by a tuner.

M8... first, welcome aboard.

Second... stop. Immediately. Or you'll be driving around in an evo with no drivetrain.

1. In this similarly titled thread, I put a very good explanation of how to properly launch an AWD car. BUT. DON'T JUST DO THAT WITHOUT READING MY OTHER POINTS RIGHT HERE!

2. Before you can really "just do it" you need to understand whats really happening. By understanding whats happening, you'll begin to understand your vehicles strengths and weaknesses and thus be able to better utilize its technology.

Now then...

3. FWD and RWD cars are a different animal than an AWD vehicle. The benefits of the AWD are largely twofold.

A. It provides EXCELLENT grip through the turns, and is able to correct MANY poor driver techniques, thus making you look like a driving God. You are not a driving God. LEARN how to drive your car, and work WITH it, rather than against it.

B. It provides excellent grip for acceleration. This isn't very different (technologically) to the car than accelerating hard out of a corner. However it is VERY different, because you're not accelerating out of a corner. The Evo, while a very capable drag car, is NOT a drag car. It is built for the twisties, and thats where it will shine. Launching the vehicle (ESPECIALLY improperly) is extremely bad for the car in comparison to actually carving corners.

4. There isn't really a situation where you should ever be "dumping the clutch" in an AWD car, or ANY car really, unless you have a transmission and drivetrain specifically designed for this. Which you don't.

You're a driver, not a robot, and its a pedal, not a button.

5. To whoever mentioned double clutching. I'm not sure how this got into this discussion (DAMN the fast and the furious!) but unless you're driving an old dump truck, you don't need to double clutch a gosh darn thing.

Questions... just ask.

 

Nice.

just ride it

 

post your VIN so I know to stay far from your car when I am ready to buy one.

 

We'll remember that when you come in here with some similarly newbish question/post.

 

I just dont understand what is going through peoples heads when they do stupid things to these cars. Lay off the fast and furious driving moves unless you have deep deep pockets

 

No kidding... That's the sad truth.
