Well my '95 RX-7 had a Torsen differential. From an engineering perspective, a Torsen is the most elegant and ingenious design for a LSD. No clutches or hydraulics; torque transfer is completely gear driven based on the input torque from the driveshaft. From a practical perspective, it is one of the most bulletproof, low maintenance diffs you can put on a car, with extremely smooth power transfer.Drew00GTsc said:anyone else?
I was checking this out for my Panoz. Decided to let the Ford 8.8" blow up before I replace it. But when I do the replacement will be a Torsen. Back when I talked to Zexel they were not yet selling the T2R; it was just starting to be "road tested" by some sponsored autoxers. So now they're selling it... nice to know.Drew00GTsc said:the question is still open in my mind whether the T2 will be good or do i need the T2R.
For your power level and application, I'd highly recommend against the T-2. Back when the T-2 was first offered my FMS for the 8.8, I tried one in my 94 GT and it performed very poorly for autocross. I was only making about 250 HP and about 300 lb-ft TQ, and the couldn't keep the inside wheel from lighting up. I tried several spring rates (front and rear), different bars (front and rear), no rear bar, etc and just couldn't keep enough weight on the inside rear to prevent the diff from opening up. The final combo included a Griggs PHB/TA set-up and the results were adequate, but not great.Drew00GTsc said:Has anyone driven 2 similar cars but one with the T2 and one with the T2R? I am looking for real world opinions. I like the 4:1 bias ratio but is it worth Global Wests $700 price tag?
I wish I could answer that for you, but I've never used the Tru-Trac or the T-2R. About all I can add based on my actual usage is that the standard T-2 works great with the IRS. I tried a very tight Auburn with the IRS and it induced loads of understeer - to the point of being unsafe. This experience with preload and the IRS is what made me choose the T-2 over the T-2R. Because the inside rear tire with an IRS is not unloaded in a corner nearly as much as with a solid axle (particularly with a 4-link), pre-load is far more a liability than an asset with the IRS. In fact, Torsen never had a need for static preload until they started making their diffs for solid axle applications.BlackSnake2001 said:Hey Blown46
Can you tell me the good and bad of both the Trutrac and the T2R?
I am looking into these for my 01 Cobra and I wanted to know a real world comparision.
