I competed recently in my Talbot Matra Murena 2.2 with my newly installed HML Limmen rebuilt gearbox with Quaife ATB Differential fitted in 2-day Sprint at Lydden Hill Race Circuit in KENT, UK.

It rained heavily on the Saturday and the car blew away completely the comparable opposition. On the Sunday it was dry and I improved on my previous best time by 3 secs. over 1.75 laps of the circuit., which in Sprinting terms is quite substantial!

The car has now been transformed quite dramatically with all the tramping and oversteer virtually eliminated on cornering. Even acceleration is noticeably different from a standing start, being so much smoother with tyre spin reduced. What is so amazing is how the Differential deals with all this seamlessly when it is a purely mechanical device. The gearbox itself also provided positive and effortless gear changes all day, which cannot be faulted in any way.

I would recommend the Quaife ATB Differential and the prompt and skilled services of HML Limmen to anyone.

Results from North Weld Sprint 29/09/10.

If I could compete in Class A2 for up to 2 litre Cars I would have won the class.

I guess it's for the timing device?

Correct. A timing beam is broken across the start line with this "Timing Strut"  to start the timing equiptment. When you cross the finish line wherever that is, there is another beam across the track which is broken to stop the timing equiptment and give you course time.

Thanks for sharing your experiences with the diff, Graham! It's really interesting that you have gained that much, though not completley surprising that it has reduced oversteer significantly and improved acceleration. I guess it's a "must have" for any serious tuning. The price is reasonable, though out of most peoples budgets, but I'd call it a mandatory upgrade for any racing Murena before you go start going to extremes with the engine!

That is a very interesting car you have build GP. Would you mind summing up the modifications you have made to it at some point?.. perhaps in a separate thread ?? Smiley

For me too Wink I'm interested in Your engine mods (for example when I saw that Your engine reaches 6700 rpm, how is it possible?).

Btw: are You using the polyurethan parts in Your suspension? I did it on my front anti-roll bar and that is a big difference, so now, when my engine is demounted, I will use polyurethan silentblocs also for rear anti-roll bar.

Hi Krede,

Hi Michal,

I am using standard matra components all round on the suspension. I once fitted solid P.T.F.E. bushes in the rear trailing arms, but found these too stiff and the rear would snap away instantly. With the Matra bushes you can feel the rear end going into oversteer and it gives you more drivability. I must admit that I would love to fit polyurethane bushes in the anti roll bars myself and also rose joint the drop links at the rear in the future, so will bear your experience in mind. Are you able to supply a source for these polyurethane bushes?

Whilst on the subject I did once remove the rear anti-roll bar completely and fit 600ft/lb springs on the rear shock absorbers. Unless you want to die violenty do not try this modification!  Smiley
