DSL Posted May 30, 2011 Share Posted May 30, 2011 Having secured a rare 3.14 diff its now time to look at getting a LSD fitted to it in preparation for the fitting of a more powerful Busa motor in the not too distant future Has anybody here used both of these in competition who can give me an insight as to how they compare in use & if one provides better low speed corner exit traction than the other at all 🤔 Link to comment Share on other sites More sharing options...
mattobrien Posted May 30, 2011 Share Posted May 30, 2011 I was at Road and Race during the week and got talking diffs. They said that the Titan diff is much better and will provide significantly more grip than the zf. Phil had a Titan on his car, and seeing it is what he does for a living,i guess he ought to know. Why not give them a call for a chat. Matt Link to comment Share on other sites More sharing options...

Roadsport06 Posted May 30, 2011 Share Posted May 30, 2011 I plan on getting my open diff changed. How do these compare to a ATB one? Link to comment Share on other sites More sharing options...
Pendennis Posted May 30, 2011 Share Posted May 30, 2011 Hi, I have the Titan unit and have raced with it. Phil built mine I have not had any issues, though car wanted to push on when diff was new, soon bedded in and has behaved ever since. I have not used the ATB, but have raced with a viscous type, if I am honest I could not feel any difference, though my times did fall a bit I doubt there is anything between them Link to comment Share on other sites More sharing options...

sjmmarsh Posted May 31, 2011 Share Posted May 31, 2011 How noisy is the Titan diff when cornering off the throttle? Mine sounds like a bag of spanners, but is much quieter when under power. Steve Link to comment Share on other sites More sharing options...
Pendennis Posted May 31, 2011 Share Posted May 31, 2011 Don't lift off the throttle then Link to comment Share on other sites More sharing options...
AMMO Posted June 1, 2011 Share Posted June 1, 2011 Pendennis My Titan LSD used to push on when new too. I hated it to begin with. But I think it's great now. Mine was set up by BGH. No whines or funny noises just a very few clunks now and then at slow speeds. Link to comment Share on other sites More sharing options...
RogerLegg Posted August 31, 2011 Share Posted August 31, 2011 Hi Ammo and Pendennis When you say the Titan settled down after a while how long did this take? Link to comment Share on other sites More sharing options...
7 wonders of the world Posted August 31, 2011 Share Posted August 31, 2011 Another option is the Tran X avaialalbe with a host of on / off ramp angles and now with the option of an even lower preload of 10lb/ft too, nice well made kit with a proven history, I was very happy with the performance of mine. You can deal direct and probably negotiage a discount and ask Steve at SPC to build it for you. Link to comment Share on other sites More sharing options...

Englishmaninwales Posted August 31, 2011 Share Posted August 31, 2011 Quoting Roadsport06: I plan on getting my open diff changed. How do these compare to a ATB one? Don't use an ATB for competition use, as is still an open diff and will spin the inside wheel, even with supersport levels of power/torque. I changed to a Titan and is miles better. The ATB is fine for road and occasional trackday use. Malcolm Link to comment Share on other sites More sharing options...
Hanns Per Posted August 31, 2011 Share Posted August 31, 2011 I have a Titan LSD from R&R in my 3.14 Diff, did some 20K kilometer with the LSD. When I got the Diff back after the rebuild I was amazed that it was not louder than before, without LSD. It was a good decision to opt for the Titan and not the ZF.

sjmmarsh Posted August 31, 2011 Share Posted August 31, 2011 Hans Per Mine is quieter than the open diff in a straight line, but makes a racket cornering on a ligt or off-throttle (it is not always appropriate to use a heavy foot on the road). Is yours quiet all the time? Steve Link to comment Share on other sites More sharing options...
Roadsport06 Posted September 2, 2011 Share Posted September 2, 2011 Steve at SPC has just rebuilt an old sierra diff for me, the diff came back like new and with a Tran X diff. He has set the preload to 10 lb.ft and interleaved plates to give the maximum surface area. He really knows his stuff and is a perfectionist. He stripped the Tran X down before fitting it to make sure it was up to his standards. Steve called me back too to ask how I was finding it. I put the diff in yesterday and only driven 15 miles. It is quiet like my open diff, I haven't tested it around corners but pulling off it certainly improves acceleration, feeling far more planted.
