Peter,

I contacted Mini Sport a couple of years ago and they were able to supply plates & other bits & pieces.

They would be well worth a try.

It might be nice have some spare LSD for John Lennon's 70th B'day. 10-9-1940

LOL... Phil your evil,

I find it funny you can still have birthdays even if you have been dead almost 32 years

Instead of celebrating with LSD, I figure id re-read catcher in the rye....LOL

All seriousness ...I did learn last night on the tele that lennon gave up drug use once he visted the corner of haight and ashbarry, in San fran and witnessed 1st hand the tragic waste of young throw away children strung out on acid....I hope thats true, even if it is, Id fear it was to late for him as I always thought he was 1/2 fruit loop short of a full bowl ... Basically just a total burn out like brian wilson from the beach boys

Sadly if he didnt die when he did, he would have been remembered as a burned out joke like ozzy ozboure, but I think ozzy will get a pass on his last years as a tragic tale ending of a rock god

Back to LSD...

Peter, you might try Phantom LSD, they are a populare choice here in the USA... plus you got the currency rate in your favor...plus they have been discounted considerably already

Prop you are still not reading the right books..

Phantom Grip is not a true LSD and the action it provides is more like a Quaife than like a Salisbury.

Danial,

I didnt know that.. thanks for sharing...

I have to get that book.

can i have $60... Please LOL.

Prop,

Apparently researchers wish to examine Ozzy Osbourne to find out just how he has managed to remain alive despite the fact he has treated his body like a theme park for so many years.

Anyway, with little to no interest in any form of hallucenogens I think I will stick to the LSD that brings a different kind of smile to my face.

The phantom diff as said above is useless for what we do, much in the same way the Quaiffe is utterly scrap aswell. However, I have been told "Gripper" diffs are a good job, but having not experienced one or had any first had knowledge with them its a bit hard to justify the purchase and shipping of one just yet.

Maybe someday though, in the mean time ill be contacting MiniSport to get me sorted.

Peter ,

can you explain the differences between quaife and salisbury ?
im building a midget for fast road / track days and wanted to fit an lsd but really dont understand the difference
thanks

As for the mechanical difference I can't be 100% sure. I am by no means an expert when it comes to them.

But from a driving perspective, a Salisbury/Plate (Tran-X, Frontline, Peter May) will retain its "limited slip" abilities at all times, meaning you have a consistent amount of grip/lack of grip.

With the ATB diffs like the Quaiffe, should a wheel come clear of the ground, it immediately turns into an open diff as per standard, which is utterly useless when your competing across a variety of surfaces and rough yards. Since it's a torque biasing diff, and not locking, if one wheel has zero traction, the other will get zero torque

Our cars run on Frontline plate diff (http://www.mgcars.org.uk/frontline/rearsus.htm) with fine spline shafts. Having spent their competition life with a lot of locking of the rear axle, clutch drops, direction/surface/grip changes we are yet to see even the slightest sign of a shaft twisting or shearing. Completely amazing considering the shear volume of nightmare stories you hear from people who have suffered shaft issues in the past.

I found this a couple of years ago and kept it bookmarked

thanks, simple and understood now , also looking at the Peter May kit its about £200 less than the quaife i was looking at so a good job all round
thanks

No worries,

Sorry I couldnt explain in deeper depth, it's not something I have looked at in greater depth than what is available and what has been proven to work for our needs over the years, but i am now genning up on it.

This list:

Salisbury/Plate (Tran-X, Frontline, Peter May)

Is not quite correct because neither Frontline or Peter May manufacture a diff. On the other hand Tran-x do manufacture their own diff which is a clutch plate type and likewise Gripper do manufacture their own diff which is a clutch plate type. Both claim to be better than the Salisbury design which almost certainly both are based on.

ATB is not a type of diff but the name given to Quaife's diff, presumably because the phrase TorSen is owned or licensed by Gleason.

Frontline use someone else's diff which they also have fine spline fittings made for. I'm also certain the diff itself is a Tran-X.

There are books with this stuff in... There is also a previous thread on the driving characteristics of various diffs in a Spridget if anyone wants to find it in the archive.
Daniel Thirteen-Twelve

Well, what do you know, Frontline LSD is a Salisbury-plate and not a Quaife what I always thought.
Arie de Best

They've probably sold both in the past as have most suppliers. Only Peter May ever listed a cam and pawl.
Daniel Thirteen-Twelve

Daniel.

Perhaps I should have worded that differently, but most people will refer to having a "Frontline Diff" or a "Peter May Diff", etc etc, hence my references above. As for their manufacturer, the original Salisbury stuff is nigh on impossible to get except through the sources mentioned above by Robert Holmes.

Tran-X do a plate diff, but it is not in any way useable as a parts supply for the old stuff which is what I was asking about.

Whether or not this diff is what FL and PM supply, I cannot be sure (i believe FL supply a Gripper, but i cant be sure)

Quaiffe as I have mentioned above is pure pants.

Pants for autotesting/rallying maybe, but its pretty effective on a race car if you stay off the kerbs

ATB = Automatic Torque Biasing, and means that the diff cleverly allocates the most torque to the wheel with the most grip. They are also ultra smooth in transition - some people find plate diffs spooky because when they come up 'on the ramp' they alter the driving characteristics of the car.

You are right however in saying that with a Quaife if a wheel comes off the ground the diff acts like an open diff which isn't great on a tarmac autotest or special stage - Go for a plate type every time.

For road cars and racing (particularly in the wet) I would choose a Quaife (if they allowed LSD's in my class). I haven't tried grass autotesting with a Quaife, but theoretically they should be the business in low grip situations...

The 'best' diff I ever used was a cam and pawl - it was smooth in transition and kept the drive in all conditions - the only trouble was it was old and eventually wore out... Still have it - anyone know where I can get pawls from...?

Cheers

Nicely put, even on track though i'm a bit greedy, so the curbs would be a definite area of use for me including some grass, and once again ruling out the quaife for me.

But i do understand that it can be used in certain circumstances, just none that would be useful for us.
