What can a small case diff take?

[Si316]

dont wanna start wrecking the 4.10 small case lsd ive got so what kinda power and torque can they handle?

Ive heard that small cases on 325's sometimes dont last long

i think it should be fine to be honest, its not as if ure running slick tyres with loadsa grip.

[Si316]

hmmm im hoping its gonna be ok

It's not about power mate it's about how you treat it, just don't give it too many hard launches.

It's torque that kills them rather than power.

As above, If you're not using sticky rubber it'll be less strained.

I'll swap a 3.9 large case LSD for your small case 4.1 if you're concerned.

[Si316]

looks like its all gonna be ok then

not concerned enough to let it go just yet

[Simon13]

what sort of power is your M10 gonna be producing? i'm just interested as it sounds like a very good car / project you have going! 4 pot screamer!!

I dont really know but ive had a word with afew people who recon it will be pushing 325 figures maybe a touch more. Im not sure tho ill have to see what the dyno plots are like when it gets sorted.
