I've had loads of LSD boxes over the years and all do that including my current one. And that works just fine Cheers buddy.. That makes me feel a lot better. I never had a reason to doubt the performance of the LSD before, and sure as hell have made use of it plenty of times. Quote Link to comment Share on other sites More sharing options...
KiNK43 Posted September 20, 2020 Share Posted September 20, 2020 Obviously cannot account for what it says in the manual. But it will slip a bit before locking up. S9b is torsen lsd rather than helical. Which I understand is almost identical but does have some minor differences which may account for its behaviour???

dr_broon Posted September 20, 2020 Author Share Posted September 20, 2020 Wonder if it's an issue where over time the torque needed to engage the LSD increases? Actually, just seen this on Torsen's website.. "When input torque is applied to a helical gear, it creates a series of thrust forces that push that gearing into the differential casing. When these forces push against the wall of the casing, that contact creates friction. As the torque load increases, so do the forces, and so friction increases in proportion to the amount of torque applied." If it relies on generating friction, then friction must = wear at some point I guess. Quote Link to comment Share on other sites More sharing options...
KiNK43 Posted September 20, 2020 Share Posted September 20, 2020 Absolutely needs load applied in order to lock up. And yes maybe required amount increases with wear. Unless your having an actual issue with the box tho. Personally wouldn't be splashing cash fixing something that isn't broken. I'm gonna film a burnout now lol 1 Quote Link to comment Share on other sites More sharing options...
dr_broon Posted September 20, 2020 Author Share Posted September 20, 2020 I sure won't be, thanks bud - plenty of cash splashing going on to not need any more added to the list 1 Quote Link to comment Share on other sites More sharing options...

KiNK43 Posted September 20, 2020 Share Posted September 20, 2020 Use a specialist insurer like footman James or greenlight. Should be able to have an agreed valuation you pay a little extra but not alot. I put 5k on mine. 1 Quote Link to comment Share on other sites More sharing options...
