I broke two records today...

[nicktechla]

I'm having a hard time envisioning getting the car into 2nd at 70mph. There should have been a lot of resistance as the synchronizers protested this mismatch. If one actually forced it into 2nd at that speed and released the clutch, I would expect the rear tires to decelerate so quickly as to break traction and force you to either kiss the windshield or lose control of the car.

On a related clutch topic - why hasn't anyone mentioned the technique of using the hand brake to hold the car on hill? That's how I learned about the clutch's friction zone and how to drive standard (on a 1978 Toyota pickup with the handbrake under the dash). I actually find the hill hold on the Mustang a little sluggish to release, I guess all those years without the technology taught me to be quick from the brake to the gas...

Same here, I still use the handbrake on really steep inclines. Especially if someone gets right on my bumper. I haven't tried the hill hold yet.

Yep, 70 in 2nd gear is basically red line (7000 RPM) if the rear end is 3.31 gears. I too would think the syncros would be nibbling like mad and not really want to engage at that speed.

Yup! There's that and he's got 3.73's which would make it even worse right?

Yea 3.73s top out at about 62MPH in 2nd I believe

It takes a lot of RPM to disengage it. I'm actually probably going to stop using the feature as it doesn't feel that useful.

A. This thread reeks of piss poor driving. Riding clutches is the equivalent of doing half a bench press. You're not completing what needs to be done and you're only fatiguing yourself. Also, why the hell are you going to neutral at 60-70mhp? Coasting at those speeds in nuetral is dumb. You are moving fast and have no power inputs for maneuvers.


B. There is no use for hand brake Hill starts when you have Hill assist.

C. While double clutch is not necessary, it is advantageous for corner entry at speed. Also it sounds bad ass.

What is the difference between rev matching and double clutching?

 

[Nazgul]

With Rev matching you hold the clutch, bump the gas, then let it out. It only brings up engine rpm. Double clutching is clutch in, nuetral, clutch out, bump gas, clutch in, New gear, clutch out. It matches engine speed with tranny Input shift speed. The Trans and motor are aligned at more equal rpms.

It's by no means necessary any more with synchro mesh, however it's an old school technique still used by some guys. I swear it still saves me some clutch in comparison to just jamming the car into gear and letting out the clutch. Like i said it's a technique mostly used in racing now, and makes for smoother downshift from high speed to low gear without upsetting the drive line all that much.

In terms of downshifting in normal day-to-day driving, is rev matching the technique that I should be using?

 

[Nazgul]

No. Like I said it's not necessary. Slowing to a reasonable speed and normally downshifting is fine (preferable for non jack-assery driving). I double clutch 70% of the time. But it comes from habits of racing and my desire to be at a high rpm to exit corners. I prefer to be at 3k+ rpms when exiting a corner. It's not necessary as this motor makes gobs of torque and could pull you through any corner in 5th at 1.5k rpm.

I also use it to downshift on the freeway to pass. I never liked the idea of going from 6th (overdrive gear) to 5th by just jamming it in the gear and letting out the clutch. It feels abusive. I double clutch grab a gear or two lower and go.

So no its not a needed skill. Do as I say not as I do in this case.

So you say not to downshift and rev match, but how would I downshift and avoid the jerkiness without rev matching?

 

[Nazgul]

When you get your car back go to a industrial Park and practice basic clutch control. I have driven nothing but manual transmission cars (besides my work car) and i still do it with every new car or motorcycle I buy.

Clutch feel. Slowing or quickening the rate at which you engage or disengage the clutch. It takes a while to learn. My cold start clutch release are a bit jerky with my car as well. The car acts goofy under cold starts and jerkiness seems to be a character of it. My clutch seems to bite lower when it's cold and higher when it's warm. It's all practice practice practice to get it smooth.
