Quaife LSD, Questions Options

[tscrihfield]

The units that Quaife sell for the 914. Does anyone know if they are torque bias or if they are a true Limited slip. This is for racing use and I would like to know if it works in deceleration as well as acceleration. Any information would be greatly appreciated.

Thanks,
Thomas

its a tb diff


there is some reason to believe that a tb may be faster than a clutch limited slip in a lower powered mid engine car

I've run locked and TB both
I can't beat my track time either way, although the TB is much easier to drive and the locked is better in braking.... but its easy to blow it also and harder on tires (constantly sliding)

my builder who is an amazing 914 driver swears that they have cut 2 seconds a lap in back to back tests with the TB over the Limited slip

driving styles are completely different

guard makes both
we had a conversation with paul once and he agreed that a TB may be faster in a mid engined car

the locked diff is generally preferred above 300hp (500 especially optimum)

my belief is that the lower the hp the more the car would work with the TB.

not sure where the exact lines should be drawn... but an opinion is that around 225 would probably swing towards a clutch limited slip

another thing I considered when choosing my tb over the clutch ls was maintenance. The clutch packs need to be rebuilt regularly

both also create much more heat than open or locked.
