This is useful when the clutch wouldn't hold the car when let up slightly. It's not a professional technique, but a workaround for old beat-up cars. Not to be confused with the heel-toe downshift. Well, it's also better for the clutch, but might not really be worth it. And not even new cars can hol...

I haven't actually tried this, but if you want to get moving uphill and don't want to risk rolling back, try this and tell me how it works: 1) Hold the brake just enough to prevent the car from moving 2) Bring the clutch back until it just barely touches the friction point 3) (if it's a significantl...

One advantage of double clutching that still applies to modern cars is if you need to skip gears on a downshift, like from 5 to 2. Because of the way synchronizers work, if you're going fast enough you might not be able to physically push it into gear unless you DC

There will always be more wear and tear at higher RPMs, that is unavoidable. When a manufacturer says an engine will last a certain amount of time, that is assuming typical use. If you keep the revs below typical use, it will last longer, and if you're constantly high-revving, it will not last as lo...

i dont think you understand what i'm trying to say. revving at standstill is normal. but rev matching from already say 2000 rpms to 3000 rpms is forcing your engine beyond normal driving conditions. theres no need to blip at such high rpms. What? You make absolutely no sense. First of all, 3000 RPM...

revving your engine doesn't hurt it any more or less than just BEING at a high RPM. in fact, being at a high RPM for extended periods of time is much worse than revving.

As someone who has mechanics in the family and who has worked with cars in the past, you have no idea what you're talking about.

The clutch is the ONLY thing which allows for slipping in the drivetrain while you are in gear. For all intents and purposes, every other part of the drivetrain is rigid.

You're completely mistaken.

It seems to me like it's easier to just come to a full or near-full stop than to try and downshift to 1st while in motion. Whatever you do, don't stay in 2nd!

Adding gas actually won't do anything if you don't also let off the clutch a little more.

The surface of a brand new clutch is rough, and so it has a bit of discrepancy between the static and kinetic friction coefficients. Because of that, the clutch will tend to "grab" Once you start to use the clutch, the normal wear will smooth the surface off and the static friction coefficient will ...

I think hes talking about hills. Keeping the car from rolling backwards using the clutch and gas is a VERY bad idea. Just use the brakes even if it is for a 3 second stop. yeah i definately know its bad to hold the clutch at FP on a hill to stop it for rolling but im talking about holding FP on a f...

When starting on a level surface, the amount of clutch wear that you incur has to do mostly with the RPM of the engine while you're starting. On a hill, you will wear your clutch less if you engage it as fast as possible.

I don't think it's a good idea to drop to idle speed in a gear if you intend on accelerating back up x.x
