Hi,

I got 6 of them ordered and all of them are for customers.
5 of them are to be used in race cars!

This will be a good test.

Cheers

It seems I was having a fairly epic "special"ness period last night, sorry Atchi!

Are these new ones going in 300s, or something else?

It will be in 340 race cars 4 off and 1 360 turbo about 320Bhp in circuit racing in Sweden.
I did tell him 280 to 300 is what is max.... :evil: but it will be a good test!

Ok, I'm interested in this, however, I am curious.

Having a read through the thread, you mention it is a torsen style diff, yet the casing looks very small to have a quaife style setup inside? I know were also talking about phantom grip style a while ago.

I just don't understand enough to work out certain aspects (I'm the type of person that likes to calculate/simulate etc how a modification would affect my car) to know whether a torsen or a plate would suit my style (I've driven both styles in mx5s, as well as plates in 4wd and such) or to know at which point I want it to kick in (I'm very aware of a car that has a torsen which makes it just grip continually, often ending a slide much earlier than you would normally expect, which is the main reason I'm dubious here)

I'm possibly keen for a future order if there is one, but just want to be able to do some reading up and some thinking to make sure it would make the positive changes I want rather than bringing negative changes that I don't.

Hi,

This is torsen type only because I could only find a guy who can make said "this is the type I make!".
I have only driven AWD with clutch type LSDs in Suzuki Cultus AWD with turbo in Mini Van. I loved it.
It only :shock: had 185Bhp at the time but it was very quick and fun to chuck it about.

If I wanted to get clutch type LSDs, I have to go to Gripper Diff and they will charge over £1000+VAT for trial one and they wants over 5 of them.
Do I have that kind of money to get it made? I may have but would I be able to sell it people here? NO!
I got 1 made for £600-ish but I have to pay for my sample diff to be sent to him and so on.
So the one Matt is using has cost me over £700 as I bought and send it to Hungary.
I haven't asked for money off him as he is my tester. I would like to know if it is working well. Is it snappy? grips OK? who knows.
I would like to test it myself and tell you but my experience with RWD car is when I was 17... which is over 22 years ago.
I have driven many front wheel drive with clutch type LSDs. But if Mazda is selling OEM with Torsen type especially in a most popular RWD in the world. I thought it should be OK.
I think real test is in over 300 Bhp race car.

Volvospec will be buying 1 but I didn't want to say as yet!

Cheers
Atchi

Just noticed this thread again.

I've tested the diff over about 3.5K miles over 8 months so far but the car's had lots of other problems that hasn't allowed me to test it too hard but my findings are as follows:

I'm using a 3.82:1 ratio CW/P in a standard b200 360
The diff seems to be working very well, it's being removed from the car tomorrow as i'm swapping a gearbox so can check all is well then.
I wouldn't say it's snappy - although i've not had chance to go too hard with it. I've not yet managed to pull away with only one wheel spinning and it takes a bit more than usual to pull away with both spinning. It's never sharply cut in while taking roundabouts and i've not that I can remember had just one wheel spinning on a roundabout. It seems to grip better than standard on country roads at 60 mph etc. If you do try and get it sideways it seems to me to be more controllable and goes more predictably. In the snow it was excellent, As i never just had one wheel spinning i didn't get stuck all that often, and when we found a bit of road to go sliding on for an afternoon, I was so easy to control and get angle on the slides, i out did a 116 and a 320 BMW and an IS200 quite easily but who knows what that's down to.

I'm not all that much of an expert on drifting, LSD's or anything but I find it's better than standard, makes slides more controllable and gives more grip for fast starts and corners.

If your after some info i've not covered just ask and I'll try and do my best to answer :)

Also Atchi, when my car's back on the road I'll pop up and see you, probably next week or the week after if you're about

I believe you bud, we did a soaking wet grass autotest in my housemates camaro a while back which has a clutch type, it was a: controllable (stunningly so) and b: never got stuck, so I imagine the snow would be the same.

One of my favourite mx5's was a friends that had a mazdaspeed supercharger conversion and a torsion, was really very very nice. Was lined up to sell Fake to buy it 4 or so years ago but it all fell through!

EDIT: Thinking about it, wouldn't snow be *exactly* what a torsen didn't like? Argh, LSD screws with your head

I think at the end of teh day this is the only likely way of getting a LSD into a 300 so you need not worry about the choice as there are only 2 options. Standard open diff or this LSD (missing out op 3 mig spec :lol: )

Unless you can blag a test drive the only way to find out how it performs is to buy and fit it.

How long have you known me Dai? You know how exacting I am of your parts ffs!

If something isn't up to my specs, I'll build one that is. Thing is, I really don't have time to anymore. There are lots of performance parts on the market that are just bodged to fit a different car, even so called custom 300 parts (and please no one believe I'm now on a witch hunt here, I'm not, there has been one >£500 part I've found to not be something I would want to buy and I won't mention what that is until I've spoken to the guy making them to see if he has a good reason for what he's done)

Normally I can do the maths on them and have a rough idea if they are any good or not, seeing as this diff is ~3/4 of the price that Steve_P paid for his MX5 with a torsen in, if it's not set up perfectly to a 300, I might as well just buy the 5. I really want to support Atchi here, I think the work he has put in given he doesn't have a 300 is getting very close to Mac levels of dedication (pre Mac acquiring all the good 300's he can find ;) ) I'm really not trying to come across as an arse, I just want to invest my pennies in the area that returns the best effectiveness.

Hi Chris,

I didn't take your post as being negative.
I work in automotive industries myself and see so many things that is laughable.
I can design and get it made by laser cutting and so on. But diff.... I don't have access to CNC milling or lathe machines anymore.
I will be taking liners out of my Suzuki Swift engine soon to fit bigger liner so that I can get more power with turbo. This engine will be fitted with 360 gearbox I have bought from Adam.
I'm accuring all of the parts I need to make my RWD project and same time, if I can make something which benefit to everyone. I will try to sell at reasonable cost.

I will be making an adjustable chamber bottom subframe for Matt later on. So may be if he tried it and works OK, I will let everyone have access to my parts.
Again these will be cost price plus £10 for my time!

Cheers
Atchi
