LSD Replacement

It's an LSD, but he makes them pretty agressive. Are you specifically wanting a locker?

cheers

No no LSD is better then a locker. I reacted on the prize it was lite to high if it was a simple locker.

When can you bring a 300 diff to this LSD expert so he can start to build a prototype. Should be nice to have a LSD to the next summer.

This contact has come via a friend. I'll ask my friend for the details, and we'll take it from there. Next summer shouldn't be a problem.

Depending on the price, I might have one myself. It's a lot of money, but I think it will be worth it!

cheers

Sounds great!

I'd like to know more. If there's some assurance of quality, and if it will be able to withstand a significant power increase, I'd buy one.

When you know pricing let me know, depends a bit of how much I have work, I might be interested also.

Quafie can make torsen diffs to 300series if we are more then 10 buyers.
Handle 500 Hk.
600£

fact about the diff:
The Torsen (from Torque Sensing) works as an open differential when the amount of torque going to each wheel is equal. As soon as one wheel starts to lose traction, the difference in torque causes the gears in the Torsen differential to bind together. The design of the gears in the differential determines the torque bias ratio. For instance, if a particular Torsen differential is designed with a 5:1 bias ratio, it is capable of applying up to five times more torque to the wheel that has good traction These devices are often used in high-performance all-wheel-drive vehicles. Like the viscous coupling, they are often used to transfer power between the front and rear wheels. In this application, the Torsen is superior to the viscous coupling because it transfers torque to the stable wheels before the actual slipping occurs.

However, if one set of wheels loses traction completely, the Torsen differential will be unable to supply any torque to the other set of wheels. The bias ratio determines how much torque can be transferred, and five times zero is zero.

Yup, that's what they said last time I spoke to them.

I've heard back from my contact. He wants a diff supplying to him so he can take a look at it and see what's what. I'll get on the case

cheers

HI
Mate of mine is trying to upgrade his 360 trials car diff before fitting the 2.5 motor he's building [based around boat crank and rods]
he breaks diffs every other event with a standard 2.0l motor !!
Iv'e been reading the posts about modding the DANA 30 diff into the 360 casing , [ on here and 300 power , voc forum ] Very interesting stuff .
It's very similar to what we do with a Ford Transit Diff into Ford English Axle[escort etc]for ford english axled trials cars
Looks very promising , ONE problem which doesn't seem to have been adressed on this mod [please put me right ! ] is that the gearbox shaft on the 360 fits inside the pinion [which is hollow and splined ] on the 240 etc from which the DANA would be sourced are the pinions not flanged to the prop and solid ?
The pics of the modded casing and diff on 300 power showes the pinion as solid , how does it fit to the gearbox shaft ?
Any pics of the front end of the casing showing the coupling ?
Cheers
Carl

Hi
Just had a bit more of a play with various 300 transaxles and it appears that the 340 four speed has a solid pinion which couples to the gbox mainshaft with an internally splined sleave
Another option to make the conversion would be to use a 240 gearbox end plate to seal the 300 gbox and fit a prop flange to the 300 mainshaft
This is presumably how the rallycross version pictured on 300power was done
If someone has a 240 diff [std one ] they would like to donate to our research we will be able to confirm the possibility of the DANA30 conversion
and give details of how its done
Cheers
Carl

Definitely looking forward to the outcome of this, as it's something I've been considering for a while too, just haven't the money at the second to chuck at the bits! I'm still on the lookout for bits so If I come across a charity case I'll send it your way.

Best of Luck
