WOW...I truly think this is the BEST differential for a street cruising car that wants to lay down some good ETs at the track...
The Powertrax design is relatively new. Quite honestly, I'm not sure exactly how it differs from a traditional "Detroit" style locker- both lock the two axle shafts during straight line acceleration, both use heavy metal innards, and both unlock during turning...
The difference is, the Powertrax piece is totally quiet, totally streetable, and until I stand on the go pedal from a stop it seems no different than the factory traction-lock piece did. No ratcheting sounds from the rear end, no clanking, it's totally silent.
And there is no one wheel peel now. Gah, my car finally launches like it should- I haven't tried launching on the ricer juice yet, but N/A if I heat the BFGs a bit then brake torque to 2200, pop the brake, and get into the gas, it really takes off.
Overall, I'm really, really impressed by this piece. As it's a relative newcomer to the market, I figured I'd share my experience.
