hello, is any method how to test front diff with visco? if it is working propertly. thanks

 

Hi, the std cosworth front diff is an open diff, not viscous.

 

Only the rear is an LSD.

 

not a 33/66? front/rear... I read it somewhere

 

So you want to test the centre VC then ?

 

yes yes..

 

video your self doing a big donut, and if all 4 wheels spin its working, if only 2 do then no

i cant think how youd be able to test it really, unless you can jack it up andstop some wheels from turning and see if the others do, really not sure

 

yes but there is visco, no? If I good know it can move 70% power from front to rear....I listen that I can use torque wrench on rear wheel (center screw) set it on 70Nm and test the power of visco ....

 

you would have to do that on the front wheel not the rear, the torque distribution has nothing to do with the viscous coupling though.

 

would the torque front to rear not change as the grip changed?

 

nope, the split is always 64/36 iirc, the viscous only allows slip between the two driven axles.
