driving 6spd gearbox ???
Over the weekend, I was amazed at this guy telling me "how to drive an s2k" More specifically in going up the gears from 1st to 6th.
I always depress the clutch with my left foot , ease off the gas pedal, change the gear and then reapply the gas pedal . Is that not the correct way to drive 5spd ???
This guy told me that you can drive an s2000 differently in that you can keep your right foot planted (accelerating) as you go up the gears. I said "huh" ???? I never heard of an s2000 having a special transmission ???
Basically pressing and releasing the clutch pedal while your right foot never moves off the gas pedal. ???
I found this rather weird and WILL NOT be trying this.
Why do you have to take your foot off the accelerator ?
So what is the method to his madness ???

Yeah, this guy's confused. And what does having 6 or 5 or even 4 gears have to with anything?? 
He's probably thinking of true power-shifting, a technique that used to be uses on purpose-built racecars with "crashbox" transmissions. They'd shift without using the clutch, and without lifting! But it's not like they wanted to -- even those purpose-built cars needed frequent tranny rebuilds. They did it because the tiny clutches wouldn't stand up to repeated quick shifts anyway, so not using the clutch wasn't that big a concern; as for lifting, the cars were carbureted, and rapid transitions from WOT to zero throttle back to WOT could cause engine misses (costing them time and increasing engine wear).
For our fancy modern cars with comuputer-controlled fuel-injection, triple-cone synchros and street clutches, power-shifting is not only unnecessary but a good way to get on a first-name basis with your mechanic.
Cheers,

I can't imagine anyone (sane) suggesting to actually upshift that way... Please do take the time to clue him in.
That is, however, how I downshift... The engine RPMs climb while the clutch is in, and it's almost perfectly speed-matched when I release the clutch in the lower gear (using a very fast shift).

All I can think of is that perhaps he's talking about the closer ratio gearing of the 6 speed transmission.
Correct me if I'm wrong but with a closer ratio between gears, RPMs go down a bit less between up shifts than with 5 speeds, and so perhaps you don't have to lift your foot off the accelerator as much as with normal gears. I still won't "keep the right foot planted on the accelerator" though (are you sure your friend wasn't on crack?
).
I'm not surprised at the existance of people like this at all though. I have a friend who's a mechanical engineer who designs diesel injectors for Ford engines, and he tells me that the oil you change every 3000 miles isn't lubrication but injector oil. Lubrication he explains is changed every 60,000 miles.
