2 things, that I think are wrong with this.
1. There is no way the car he is talking about still has an exaust manifold, almost garanteed to be a header.
2. Exaust manifolds don't have welds, he is again talking about a header, I believe.
Not to mention how ridiculous the comment is ANYWAY. After all, I know how common it is to "blow the welds on a exaust manifold"

From what I have learned talkin to some people I know double clutching dosen't make much of a differance. Friend who USE to streetrace in late 90's said he never did and I never knew him to of lost a race.
lol.. alright i get the concept of double clutching now, i was practicing it earlier when i read the site that was posted, i might go out and practice it a bit more later tonight. It, from what i think, is a valuable technique, and that site is that was posted on the first page was helpful.

No one really double clutches anymore. I think they might still teach it a Skip Barber, but its mostly because they want newbe drivers to slow down and realize how they're driving, and save dog rings (none syncro trannies).
Shifting a none syncro'ed H pattern box without a clutch feels awsome(when done right), and is a lot faster, and you got a free foot to left foot brake, which is a must to be competitive in most racing- ie Formula Atlantics, Mazda.
Then there are sequentials.... anyone got one in their Evo yet....??

Not that it hurts anything doing it either way.... just dont be a boob and try powershifting (no clutch) if you enjoy having synchros, no matter how good you think you are at it.
I also single clutch I can't stand the lurch if I don't blip the throttle. Powershifting is a no no if you want your tran to last.
90% of the time I rev-match before going into a corner... First off, it saves me time on footwork and less time I need to depress the brake going into a corner. And yes, that lurch is annoying...

Ah fer cryin' out loud, double-clutching my exhaust pipe! If ya wanna to go fast, all ya gotta do is stop watching hollywood movies and learn to shift fast!
You can shift our cars in literally about the time it takes to move the lever. You don't "depress" the clutch, you slap it, pushing it in & letting it out as fast as you physically can. You start to move the shift lever at the same time as you start to hit the pedal (your foot should be off the gas in that instant, so there's very little load on the tranny and you can safely disengage one gear before the clutch is in). As soon as you get into your next gear your foot should be entirely off of the clutch and your right foot should be hitting the floor with a very loud slap. On the stopwatch, I average about 200 milliseconds (1/5th of a second).
The 1st to 2nd shift is easy, as is 2nd to 4th, but once you have the 2nd to 3rd shift sufficiently well-practiced that it's a single, diagonal motion (not forward, right, forward), you're going to be beating slightly faster cars regularly.
For downshifting, just heel-toe (or rather, in most imports, left ball of the foot-right side of the foot). Just takes practice, but once you get it, you've got it, and you'll be hooked.

The only shift I'm not fast on is the 4-5, it's just not a natural movement for me, pushing right and away. I also suck at heel-toe (more like left/right side of size 13 foot), I need to work at it more.
