Looking to finance another project, so might sell my spare turbo S tranny. LSD, cooler, hardened 1st & 2nd. In good shape, 100k miles.

Any interest from the peanut gallery?

Price would be around $1200.

I also have a NA tranny - would let that go for $250.

 

Mind telling what project?

 

Not at all - a Guard 50/80 LSD.

 

Van I'm trying really hard not to hate you. 1200.00 with local pickup would have saved me some real coin about 4 weeks ago.

 

Come now John... I offered to loan it to you for free.

 

I didn't want a loan. lol. I wanted a new tranny installed and not have to mess with it anymore.

 

$1200 IMO would be a steal. $1500 would be a steal. If you sell it that cheap I hope it goes to an end-user and not a parts dealer.

LOL - maybe that's too cheap then!

Actually, after sleeping on it, I'm not sure I really want the Guard LSD... I'm unsure how much of an improvement I'd see... would I really see a $2k worth of increase? $2k covers 2 long race weekends!

 

Van,

I dont think you will see a huge difference between the Guard 50/80 and a factory stock 40/40 unit, assuming that your stock unit is in good working (locking) condition. The noticeable huge improvements are between any type of locking differential and an open diff.

I have run cars with stock LSDs, Quaifes, and modified LSDs up to 100% lock, and there is not a huge difference between any of them. The big key is that you are not spinning an inside tire going around turns, and that the car is putting the power to the road when accelerating out of a corner. You do notice no-lock under braking (Quaifes), but I dont think you would notice 40% vs 50% lock under acceleration.

Note: but with that said, those percent lock numbers are somewhat misleading as that is not a true measurement of slip/lock. I think they should be rated by breakaway or slip torque, that would make more sense to me and make it easier to compare different units. So I am not certain that a Guard 50% LSD requires only 10% more torque to slip than a stock LSD.
