Title: small case 4.10 strength???
Post by: e30_kid89 on September 24, 2006, 10:35:04 AM

how much can these sweet units take?? a friend of mine wants to run the stock small case 4.10 LSD with a modded m20...can it take the power or will it blow? i heard they can take up to 210ft/lbs of torque.....is mr guibo running a stock 4.10 with his lil monster or has it been already swapped out? any good info would help.

I've heard of people going through several of them with M20s, some mild modded. Much of it has to do with driving style and wheel/tire size as well. I fear for the life of my 4.10 LSD and I really haven't done much to my motor.

Title: The usual.

Typically differentials are ran until they make horrendous noises or break. Most also have an average of 150,000-200,000 miles on them and are also over-engineered. F1 cars of twenty years ago ran a Hewland that was originally rated for 450 HP and they held up at 900 HP. If a small E30 is setup right it should be good for 300HP. But that's a wild ass guess.
