Turning brakes are for taildraggers.

That has crossed my mind..

That has REALLY crossed my mind!!!
I figure this fall when I do my teardown for powdercoat, I will be calling Dean to discuss my options on the diff if there are any....

My biggest complaint of only having open diff in the Jeffco is trying to accelerate HARD out of a turn. Inside wheel unloads, traction lost, speed lost, and the gut tickling G's are lost. Not to mention the hellish loads that has to put on the side and spider gears of the open diff.

Although I have never been for a ride in a car that the guy actually USES his turning brakes!! Maybe I would like em'?

If you ever make it over to the Oregon coast let me/us know we can give you a ride in a busa powered car with cutting/turning brakes.......I have also had both(LSD and Open) and true the lsd does offer some advantages over a open when it comes to the traction you where refering to, but like Gene said if you have ever rode the Oregon dunes and trails you would find that having a car that plows and does not turn worth a shit isnt worth the small advantage in traction the LSD offers. Now my prefered setup would be a air locker......locked when you need, it unlocked when you don't.

NOW WE'RE TALKIN' !!!!!!!

I would love to get out Oregon. Thats gotta be some of the prettiest dunes I've seen...In pictures I mean..

Is driving a locked rear impossible in the Oregon trails or just a big pain in the ass? I haven't had much of a chance to get the Jeffco in the sand yet to even try trails out..

Turning a car with a locked rear isn't hard. You just have to carry speed and judge the slide correctly. I follow quads through dunes that cars with turning brakes won't even touch. The turning brake guys seem to be more point and shoot, and don't carry much speed through the turns. It's all a matter of preference I suppose.

Most buggy's need turning brakes because they don't have enough weight in the front.

Driving on rough terrain in Baja makes a spool a lot more attractive. When your going up a whooped out hill with a lot of loose rock on top, a spool is your best friend.

[busasandrail]

Dune is right you really have to pick your path before you get there. And turning around in a tight area is a challenge. Driving with a LSD diff just limits the cars abilty to turn really well. Like I said before I have had both and both have there advantages, just where we ride and the style of riding we do, having a car with a LSD doesnt preform as well as a open with cutting brakes.

Once again the answer depends on the usage.

Anyone here have any "Detroit Locker" expierience?? My understanding is at very low power to no power (coasting or pushing around parking lot) they are open. But any amount of power they lock solid and deliver to both tires. Not to mention they live in all sorts of axles with all sorts of tire sizes and are supposed to be tough as all heck. I do know they click somewhat like a rachet but its not so bad that it would scare a minibuggier away.

I have seen these in trucks but never drove or rode in one. That said they cannot be used with cutting brakes if I understand right as locking one side with the cutting brake would make the diff lock up and drag both sides down.

In theory when letting off the power on your mini buggy the diff opens and allows diff operation between the rear tires. Yet if you stand on it it locks up solid. They do not use "normal" LSD slip pads that wear but a large rachet mechanism that does not have any diff action with any good amount of power applied. Driving gently on the street they seem to allow the tires of trucks to do there thing without squealing but step on it and its squeal city.

These might be a diff IF one was made that would fit in somes rear end unit.

There are also Audi Quattro rear diffs that can be run open or locked with a mere lever pull. I have one here but was looking at feeding power into the stock front pinion flange. I have been told that these lock in under power in the cars and been told that they cannot(so I am not sure about this area). I also do not know what it would take to remove it from the factory stock housing and drive it with a chain or maybe put it in a Jeffco or similiar housing. Bill

My experience with Detroit lockers is, They suck on the street. under load they pop really load under a load when they ratchet and give a nasty lurch. In the dirt they are so-so. After breaking several, I went to a spool. I have know idea how cutting brakes would effect them, but if it's anything like turning on the street it would be very annoying.
