Diff re-gear and clunking noise
Hi
Just dropped the beast off for an MoT after the engine swap (pinto out, E36 325 straight six in) - serious butterflies!
Haven't been on the motorway yet, but the way the gearbox / diff have mated have left it with pretty short gearing. I think it's an XR4 x
4 LSD (so is that going to be 3.62?). Does anyone know if I can get the diff re-geared to raise this a bit - short gears are fun and everything, but
from the way this thing pulls I suspect it will limit my top speed, and mean stopping to re-fuel every 100 miles on the motorway... Comfortable
cruising in 5th at 40mph at revs I was hoping to use at about 70mph!
Also getting a fairly substantial clonk from the transmission when you go from acceleration to engine braking - MoT guys going to have a quick look at
it, but any suggestions welcome. Thanks!

Clunk going from drive to over-run will be play in the prop or diff.
Check your diff and hubs are all bolted up tight and if it's not that then the diff is prob worn.
I think you can get 3.14 diffs. Also, you can get new gear sets for the T9 but you would probably be looking at £500 plus. I close ratio set with long
first is on my wish list.
Are you a Mac user or a retard?

I doubt he is using a Type 9 with an inline 6 Beemer engine?

Good point. Bit early. Brain isn't fully engaged.

It is a BMW box.
Does the 3.62 refer to the number of times the propshaft turns for one revolution of the driveshafts? There is a 3.14 on the list that I got off here
somewhere. But still, say that x propshaft rpm =45 mph with a 3.62 diff, 45 X 3.62 / 3.14 = 52mph... not a huge difference. Is my maths right?!

ISTR the E36 M3 had a ratio of 3.15, good for 150mph+, Similar Sierra diff from a diesel jobbie is around that figure, so should be fine.

Larger diameter wheel/tyres (if they'll fit) would help
ACE Cafe - Just say No.
