Re: Double Clutch (1990_DA)
Just something out of Fast and the Furious. Just like all the other myths...titanium valve springs, Nitrous oxide being flammable, blowing welds on the intake, green, red, and blue fire coming out of the exhaust when revving...nitrous causing massive wheel spin in 4th gear. It's all bullshit, you can't believe everything you hear in the movies. Double clutching is used to shift gears in a non-synchronized tranny. It is also used to reduce wear on synchros, or if you've worn out your synchros, you can get it in gear without grinding. Also makes for smoother, better downshifts.

This is not true. Yes, our trannies have synchros and you don't need to double clutch while slowing down. BUT it dies decrease the wear on the synchros. Think about it, that's why a lot of people have problems with grinds -synchro tear and wear. If we went by what you said, then there would never be any wear on the tranny because "we have synchros." You don't need to do it, but it does help the tranny out as far as longevity goes.

Re: Double Clutch (1990_DA)
my concept of double clutching for aggresion is this
ok your in first gear, your run it to redline, then you shift to second, say your RPMS drop to like 4000 so you slam on the clutch again, (while in gear, with the gas too the floor) then just step off it really fast, thus your motor will rev up to like 5500 or 6000 and give you a little extra boost at the beginning of your gear.
Dunno if this is considered double clutching or not, but it gives you alittle jump, and tears the **** out of your clutch.

The JDM trannies just tend to have weak *** synchros anyways...
that reminds me, i need a rebuild soonish

That's what I was trying to say. You don't need to do it, and you won't be any faster if you do it, but if you do it correctly, your synchros will last a lot longer, because you basically are bypassing them when you double clutch. And yes, I can vouch for JDM tranny synchros, they suck. At least mine do. I need a new tranny soon, because I have to double clutch just to get into 3rd gear, or drop into second.

Why dont you just leave your foot on the gas and not let up until your done accelerating. Just leave your foot on the gas and when you shift, dont let off the gas. I think its call "speed shifting". Not sure, i remember my dad telling me about that in the old days which american muscle cars. To bad most american cars now suck.

That's the way I do it when I race. I just leave my foot to the floor the whole time. It's actually called "full-throttle shifting". I think speed shifting is when you don't use the clutch at all, you just wait till red-line, and yank the shifter into the next gear. I don't know exactly how to do this, because I'm not trying to grenade my tranny. There was this kid at the track with a stock GSR in a hatch running 7.80 in the 8th. Everytime he would shift, fire would come out the exhaust. I asked him how he shifted as fast as he did, and he told me he doesn't use the clutch, he just waits until redline, and shifts. Anyone else heard of this, or do this?

Sounds like a sure fire way to blow the tranny..
Maybe he had a tiptronic tranny er whatever =D
I'll have to try that full throttle shifting next time i hit up the track

Yeah, I dropped 2 tenths of a second at the track when I full throttle shifted last, and it wasn't a fluke. I used to run 10.2's consistantly, then I tried the full throttle shifting, and dropped to 10.0. Then I converted to obd-1, and dropped to 9.80, and I am running that consistantly.

This is called clutch kick.....i don't recommend doing this all the time wears down the clutch pretty fast..i only do it when i get a bad launch and my RPM's drop too low, or when racing from a rolling start on second.

if u keep the gas down all u do it get mad wheel spin or i do at least
and when u dont use the clutch i just call it "power shifting"anyone agree

I don't have enough torque to get wheelspin.
Actually, when I shift normally, the clutch grabs hard, and I get a lot of wheelspin, but when I make full-throttle shifts, for some reason it doesn't even chirp the wheels. I think it is because I make full throttle shifts maybe 50rpms before rev-limit, so as soon as I put my foot on the clutch it hits rev-limiter, and before it bounces and drops 200rpm, I'm in the next gear.

Re: Double Clutch (four1one)
me and my buddies don't use the clutch in close races, we just call it rip shiftin' or rippin the F*ck out of it... It's a honda you gotta break it before it rust apart....
