had a hydratrack diff fitted 4 to 1 its what they use in the racing tuscans i am told ........
You're misinformed I fear.

They use plate diffs, or Quaifes if they have more cash to spend. wink
Might be the case but its a lot faster than standard setup
Neil,
Its probably slower but quicker. wink

If I'm honest I ran a hydratrack diff in my Sagaris and had very little problems with rear wheels spinning - maybe partly down to correct rear ARB setttings??

I just did my first track day at Brands today. My Tuscan has the hydratrak diff, the day was dry, then wet, then dry and (as I got more "familiar" with the track..) I pushed really hard and it didn't feel out of shape at any point. A couple of twitches at times were brought back in line with a minimum of effort. No doubt this isn't only down to the diff but I have a lot of confidence in how the car behaves and if the hydratrak is responsible in any part to this then I'm happy with it biggrin

Just my tuppence...

PS: Had a real blast and enjoyed every minute of it, must do it again!

Glad you had fun! Agree it's perfectly controllable below the tyres' limit of grip, and quick to regain grip if you've lost it through a quick burst of too much acceleration, which is why TVR fitted it for road use.

But it's poor at providing a predictable smoothly balanced slide, controllable with your right foot, IF you're pushing hard enough to spin a wheel quite often, and if you have had something better to compare it to.

Experienced roadtesters quickly found the same thing on the track in Tuscans & Cerberas, and said so. Then again, sliding isn't the best or quickest way on most tracks, just gives extra margin of control/predictability if you overcook it smile

Fair comment, I understand the benefits of a friction/cone type diff, I just didn't feel that the hydratrak came close to messing me about today, that's all biggrin I'm hardly a pro driver though.... wink

I got asked "are you going to be changing gear at 5Krpm then sir?" hehe I only rev'd it up to just over 3K first off so he asked me to put it up at 4K and measured 98dB which was cool as I was expecting around 100db.

It would have been nice to have been able to use the CCC's though, I missed the noise tbh but had a great time passing various cars by hard on the throttle winkbiggrin

Yeah, tapered decat pipes (a la NTEL), standard cans and standard bore exhaust...might even squeeze in on a 95dB limit if the guys measuring are "friendly"...

"Personally"............ I'd prefer the Quaife ATB Diff. Fully fitted at around £1200 (Including new diff bushes), or do it yourself for alot less.

I have friction plate lsd on my cossie (Rwd 330bhp @ wheels) and standard 4.0l Chimaera its quality for the fun factor but find that the coz is hard to keep in a straight line 4th through 5th when there is moisture on the road, never been on the track. Pretty certain its the same manufacturer for both Which is Borg and warner.Must say though My Tuscan s (hydratrack) seems more controllable in the same conditions when I don't want to stick the back out but want to put the power down. Eg: Tuscan early yesterday morning 6.30ish whilst traveling to work there is a stretch of road which has that nice smooth tarmac, and when pushing 3rd through 4th you can feel the diff pulsing from side to side keeping the car straight and allowing to keep the power on which seems to give a good sense of sercurity. Noticed on occations that if the back does step out a little to far it not to agressive on snappong back into line. Now I been traveling this same road now for approx 20 years to and from work. Cozzy, Had this car for 15 years and know it very well on the same bit of road in sameish conditions I would have to let of the power a small bit otherwise I be faceing the wrong direction. If you let the power of to aggressivly this can have an adverse effect and cause the car to pendulem the other way. And believe me I have lost this car a few times but been lucky!
My opinion is that a lot depends on what you want from a car and diff.
Must get to Brands in the summer. Will have to get a set of standard cans first though.

been to see a tuscan mk1 (2000) for sale, and the dealer could not confirm the diff

do all tuscan Mk1's have hydratrack fitted as standard?

95% standard Lsd fitted, Hydratrac not so common because it was a option, exept the later TuscanS,
but even at later cars the factory fitted what was available (laying around)
because of lasyness/financial failures.
Only easy way is checking the aluminium type plate at/around drain plug!

I have driven both, Hydratrac now and normal Lsd before
The Hydratac makes car much more safe and can really prolong the life span of the car!!
