I know that a Detroit Locker or a spool would be better, but I would like to be able to turn occasionally. I've read a ton of mixed opinions about the truetrac. It's actually kind of odd: some people beat the hell out of them on the dragstrip with 600rwhp, slicks, clutch dumps, etc, and say the TT is taking everything and asking for more. Other people break them on their first trip to the strip with 400 rwhp and drag radials. Does anyone know if there's something during the set-up/install that affects how durable the unit is?
Detroit Truetrac durability on dragstrip with slicks, clutch dumps, etc

I haven't read of too many people breaking them. like you say there are big hp guys running them with success. if set up correctly I bet it could take just about anything you can throw at it. I am very happy with mine for both street and strip.
Thanks. The "set up correctly" part is the thing I'm most interested in learning. I mean, how does one set these up for drag racing duty?
No issues here. I was getting 1.4 60's all last year with IRS and I also open track mine.
I have a Detroit Locker with sra & have no issues with it on the street. Newer units are much different than from years gone by. This is my 3rd supercharged Mustang using a locker. For $700, you could go with an Eaton ELocker http://www.mustangandfords.com/how-to/drivetrain/m5lp-0404-eaton-elocker-differential-kit/ http://www.jegs.com/i/Eaton/362/19660-010/10002/-1?parentProductId=1032956 but again, I have no issues with my manual locker.

600whp? How about no issues with plenty of 1k whp reviews I've read! BTW Clutch Dumping is improper on many parts not just differentials. If that's how you drive I hope you have deep pockets.
Yeah, they're pretty much clutch dumps or at least very fast slips, you can see how I launch here:

Slipping the clutch vs dumping it like in the video translates to an extra 0.2s in ET. I have hundreds of passes like this, it's not that hard on parts, especially with the huge sidewalls on my 28" slicks. I know everything will wear out, I just hope that the Truetrac will last at least 150 passes, instead of 20 or 30.

When you said "dump" I was thinking side stepping. You'll be fine.
Detroit lockers are not that bad on the street, and will turn just fine as long as you are coasting. If you foot is on the gas it is locked, and will slip the inside tire.
Gears setup for the strip are usually just tighter, less backlash, although as long as they are in spec they will be fine.

With the Detroit Locker, it seems like you would have to be very cautious during turns b/c it may unexpectedly lock up. Well, I'm not worried about slow turns on local roads, but it concerns me when I think about highway speeds -like around a slow bend or something where I need to give it a little gas. Add a wet or damp road, and it seems like it could even be dangerous.
If I break the True Trac quickly, I guess I'll have to get a locker or spool and limit street driving

I run a truetrack with 1000 HP and not an issue. Great driveability, no noise, and just looking at the thing you can tell it's a solid piece. If you still street drive it, I'd go with a truetrack
Thanks, do you drag race it, hit it hard with drag slicks, etc?
Thanks for chiming in!
