ASA has a ProAutoSports PS0 class where the Trak Paks race... I am not too familiar with it. Just know thats where most of the limited production Trak Paks are being raced.
From what i understand, the true trac acts like a normal LSD during normal driving, but almost like a locker under stress correct? the main thing that many people seem to like is its gear driven, no clutch paks which means it only goes if its trashed. I think that may be one of the main reasons autox went with it. after reading his posts, it seems like his biggest concern was having something that lasted.
Now im not a corner carver, i like straight lines. I dont see how the true trac would be beneficial for corner carving. sure its durable and no clutch packs to replace, but if it acts like a locker under a load wouldnt that be bad for corner carving,
Gray Ghost GT said:Which 8.8" 31 Spline LSD is STRONGER - the Eaton #19588-010 or the Eaton Detroit True-Trac #913A561? This will go in a daily driver that will see a lot of road course time too. I plan to have an upgraded LSD installed this January that can take a lot of abuse without making too much noise. Thanks!
Truetrac bias ratio: 3.5:1 Can fluctuate (+/-) with type of oil used...
OEM T-Lok: 2:1 at best.
And pray tell, how do you think the bias ratio actually changes with oil? Don't get me wrong, I play with oils because they are friction devices, and a thicker oil can help a little. I found that helicals worked better with cold oil (like first runs when the car was trailered in), so I tended to run a heavier oil.... but nothing that could be considered a changing in actual mechanical ratio--because that's dictated by the angles cut on the gears.
I’m running a Torsen T2R (same one that comes in the FR500). It has so much feel that you can tell when it is transferring power to the tire with the most grip while exiting corners. It tells you everything you have going on with your rear contact patches and makes charging off of corners very uneventful. I have run the Truetrac, Auburn, Auburn Pro and the OEM trac Lock with the carbon plate pack in the past and the Torsen is lightyears better IMHO.
