OBD1 s52+3.46 lsd+ZF 320 = OMFG!

[e30polak]

I'm running a 260 getrag with a 3.73, I'm assuming 3.46 w/ ZF is shorter?

Traction isn't a problem for me either unless it would involve launching. I can floor it from a stop and not really lose traction, just a little spinning at the top of 1st.

Running 225's.

Your gearing is closer to a ZF with a 3.25, a 260 with 4.10s is almost the same I believe.

i have a 3.25 now with the ZF and i want to go the other way, to a 2.93! i don't even drive on the highway all that much.

If I drove more highway then I would've gone longer, but I now have a street demon! :twisted:

traction is really that much of a problem for you guys? hmm, s52 must put out alot more power then s50, i cant break my 235's loose unless i try.

We have a little more torque, but I have to gas it up, or pin it from a dig to lose it. And I only have 215/45/17 bfg kdws?

I guess I havent driven mine hard enough to know yet, but so far I'm digging the OD Getrag box with the 2.93. It has loooooooooong legs.

I think bumping it up to a 3.46 might be nice, but while I'm doing primarily highway driving and hardly any track days, it doesnt matter much to me.

Oh wow, that's even worse.


Did it snow last night? There is something that looks suspiciously like snow on the tree outside my room.

I think your contemporaries are playing with you. Think of your tree as "The Dome".

Think creaky senior citizen patella.

You forgot the noise the coils make over the expansion joints on our fair freeways.

Are those more of a *crunch* or a *boink*?

[Farbin Kaiber]

let me simulate what it sounds like on the highway.

BLEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

The shifting isn't all that bad, it's the tach out that sucks the most.

man first gear and most of second gear is pretty much pointless with the 3.25 even with 235 rt-615 tires. how hard is it to get traction with the 3.46? And i know gearing doesn't "give you power" but does it speed up acceleration? what is the gears strong points?

Anyway, glad you found a bad ass drivetrain setup.

I don't really care about launching, that's pointless in a 24v e30. If I roll from 20 it's fine. I normally punch it in high first, then there is plenty of traction.

Can't be as good as my 2.93


But I second the traction question. I can't hook 1st even if I roll the throttle in, and that's with 245/45/16 Z212's. They're probably heat cycled out, though :D

I can't imagine a 2.93, even though the longer 1st and second would be fun. I did the 3.46 to have a shorter 3rd and 4th, and that's exactly what I got. Traction sucks balls even with the 3.25, I'm not drag racing here. The 3.46 is a very peppy daily gear! :-D

[Farbin Kaiber]

You'll be cranking at least 4k at 70 if you use a zf with 3.73 gears. Those are way too aggressive for a DD. Jesse runs them on his m52, but there is way too much shifting involved. :crazy:
