Pretty kickass track video

[Beej]

A friend from back home recently made this and edited it. It's a 91 318iS at Watkins Glen. Mods are H&R Coilovers, ST (22/19) sways, i/e/c. He was also on 2-3 season old BFG G-Force KD's.

I dunno how long I'm gonna have this cesium webspace, but:

Pretty cool to see the 134hp car pass the 996 and e34 M5. I love watching the keychain float to either side.

Awesome man!

nice video. the camera angles are really cool. I didn't realize the walls were so close at Watkin's Glen.

Whats his technique called where he blips the gas in neutral before downshifting? is that just heel-toe or somethign else?

Someone didn't check his short sleeves in the paddock :wink:

Double clutch

And he's not granny shifting.

Maybe he wont blow out his onion rins on track!

[Beej]

Yeah, for some reason he prefers double clutching over just regular heel-toeing. Habit, I think.

[.RJ]

Easier on the synchros.

[JackoliciousLegs]

Easier on the synchros.

That's how I have been taught but what makes it easier? What's spinning when you double clutch that isn't when you don't?

With the clutch disengaged and the trans in neutral, you match the input shaft speed to the gear you're going into.

[JackoliciousLegs]

But can't you match the speed w/o double clutching?

[.RJ]

But can't you match the speed w/o double clutching?

You can match engine speed to road speed when going into the next gear (heel-toe).

To match input shaft speed, you need to double clutch. Usually the syncrhos do this, but it just makes it easier on them, or if they're busted.

[JackoliciousLegs]

cool cool... i get it now! Thanks RJ

[Beej]

Easier on the synchros.

Well yeah, but that's not why he does it (though it is an added benefit).

[BLINGMW]

yeah, I'm guessing his syncros were on their way out, otherwise there's just no reason for that. E30 trannies are well built and cheap to replace. Habit's cool though. :wink: Fun vid! Lots 'o cameras!

[Kaan]

skippy calls it "the blip" in his book...

[Beej]

I've driven the car - the synchros are fine. It's just his driving preference/habit. He feels as though the double blip of the double clutching is old hat and sets him up better than a regular single blip heel-toe.

[Evan]

when the clutch is engaged, the input and output shafts are connected, so you are spinning up both at the same time, as opposed to just 1 when the clutch is in.
this is normally what the synchros do.
which is why you can also shift without the clutch by matching revs.
