Toenail.....why are you reving your engine and what type of engine is it? Anyway, neutral is always used for stuff like that or..... unless you're in gear with your foot on the clutch.

One method of spinning the tires is to get the car rolling, then rev the engine as you depress and release the clutch quickly. This will bring up the RPM's and cause the rear tires to break.

I'll rev the engine during downshifting "heel toe" to completely control the car during heavy braking to match the RPM's to the gear i'm d/loading to. Just depends on what you're trying to accomplish.

Also, as far as damaging your engine, again, it depends on what type of engine it is. Do it to a stock pos cavalier and you may break things....do it to a worked small block and you can do it until the cows come home without damaging a thing.
