Have fun with it, even with a quiafe diff I am still getting use to that, but I love the way it pulls you out of a corner,

saying 50-60k is a guess at best ,I cannot think of any highly tuned saxo ,or any other track car that would ever cover 20k in 10 years racing
most races are 20-40miles at most +10events a year = 400mils.
I can say for sure that if a plate dif is doing much+ big power it will not last anything like the 50k .

Well we shall see how it does

If it needs rebuilding then ill get it done its not a huge issue tbh
car does around 6k a year including a trip to germany annually so im good for a bit

easy to check, one wheel on floor --torque wrench on other wheel in the air +see what reading on torque wrench is when it starts to slip--then check again after some mileage --as it wears the torque will drop off .
from ack to back testing i reckon a quiafe is same grip as a plate dif at 40lbs

AlexB^p · 27th May 2011, 07:05

This seems a bit more than that when swapping my wheels about but i only ever uses ratchet then torque on the floor
ill check it off the hub nut quick next time im doing the wheels

axsaxoman · 27th May 2011, 08:38

I would expect it to be at least 60 --more like 80 lbs,we used to run a plate dif for racing at 100lbs .
this is not definative as the ramp angles also effect how sudden the grip on a plate dif is ,but it is a guide for you tell when its getting time to replate it

AlexB^p · 27th May 2011, 09:54

I remember john saying 75lbs but that may be the springs in it and ive got 45 ramps rather thanthe race spec 60/30

axsaxoman · 28th May 2011, 22:10

well you know how to test it now

AlexB^p · 3rd June 2011, 23:14

I meant to earllier but i forgot my torque wrench

fail lol

Unfortunatly my review may have to wait a little as so far with this and my r888s fitted it definatly no longer llights up my inside front tyre but because of the grip now its making my clutCh the weak point in my transmission and it now slips and basically is duff

Once the paddle cllutch is sourced and fitted ill get on with testing

Cars next planned outing is july 1st at a llittle place in germany

My gripper was specc'd incorrectly by the retailer and was horrible. Sent it back to Dave Mac for a change. We've now got it in the car but haven't tested with aggression - I'll let you know what it's like after our open pitlane shakedown on sunday. I'm hoping it will be 1000% better!

AlexB^p · 4th June 2011, 18:09

mine was specced for me by john mac (daves lad and now owner of the buisness as daves semi retired) so hopefully itll be sweet

it feels pretty good below 3k just playing about
