Left-foot Braking in Historic Trans Am Mustang

[bordercollie1961]

What vintage racing group allows a Jerico Dog Box?

[rtrestorations]

@bordercollie1961 SVRA (with 150lbs weight penalty). Hard to find quality parts for top-loader trans.

@rtrestorations - ok that makes sense....I am a CVAR guy and we dont allow that kind of stuff in the big cars. Great video by the way...

[surrenderonceagain]

I{m an ignorant it´s auto or man?

[rtrestorations]

@surrenderonceagain Manual gearbox!

The reason he taps the brake before the brake zone for the car is to set the brake pads to make sure he has a good pedal feel. With a car that has alot of vibration the brake pads can move some distance away from the disc when you apply the brake you have to push quite a distance down on the pedal to get the same brake force as you would if you tapped the brake to reset the pads closer. Hope this wasn't to confusing.

@Arielfall1 Thats a good point. Can it also be upset by using the curbing a lot?

[MSRCWB]

I'm curious, what kind of gearbox is used in this Mustang?

Have a special clutch or the changes are made in time?

[rtrestorations]

This car has a 4-speed Jerico and a standard racing clutch -- nothing too special. The reason we can shift w/o the clutch is because the gearbox has dog rings.

He's using the left brake while he can easily do the same job with a heel/toe braking and accelerating. Left foot braking is only to maintain the car speed while accelerating on curves, bumps or any situation where the driver need a quick reaction.

[ingrowntoenailman]

into corner - brake - accelerate - brake - accelerate - brake... finally accelerate, steer a bit... why not pick a speed in, maintain it through and accelerate out, not all this messing about during the corner...

[B0SSNINE]

He only did that on the big right turn...

@ingrowntoenailman

Eh, heel-toe works best when modulating the brake and striking the gas for a smooth downshift. The big right-hander that he's doing the most left-braking on uses more gas pedal modulation than brake. Heel-toe would be a hell of a leg-twist if you intend on flooring it in a second or two, hence the left-foot brake tapping. Plus, as was stated above, speeding up brake/brake to gas transitions is key. Unless you're running some sort of enduro, coasting is a waste of lap time

great video. This car sings!

[haroo69nz]

hey great footage-no pun intended,what do you rev this too as it is fair singing along.Cheers Leon

[rtrestorations]

Glad you enjoy! We rev this car to 8200rpm. It's a 306cid small block putting out 550bhp.

[badbob91]

well you can use the brake in the corner for trailer brakeing, there should never be a point in time in a race car where you are not accelerating or decelerating

[NYConnoisseur]

yes. otherwise it is only really used for bracing in the corners, right? Should really have a stick for road racing though. Not that this guy used it once, seamless clutch less shifting at its best. Awesome video.

[Hate666Breeder]

Is it a good idea to use this Left-foot braking with an auto trany on a race track like this one?

[rtrestorations]

It might be worth a try, as it may allow you to control the car a little better through the corners and speed-up gas-to-brake/brake-to-gas transitions.
