Totally custom halfshafts, hoping not to break at least the stock crappy halshafts in hard lunches. It was a hella work to make these fit and work.

where/who did you get these from? (and if you don't mind my asking, how much have you put into them??)

Also, what Diff are you running? I'm doing an LS1 swap into my e30 so I need to beef up the rear end as well to handle 400+ hp & similar torque.

Cheers!

looks amazing by the way!

Garret, don't bother. My e30 rear end handled 620+ bhp.

Or would you be willing to fab up another set?

-DanThanks guys.

About fabbing, hmm, I'm not sure. Parts for donnor are not commonly found in junkyards over here. I just had some luck and had these parts.

E36 compact armsis what I'm using for my 5 lug swapp (wich is done) that's why I'm using the e36 abs ring as you can see in the pic.

The beefier part are Jeep front drive shafts with the newer u-joint wich are damn strong. I had these laying arround in my shopp. Not anymore available in my shopp, less the BMW halshafts.

They are fully balanced.

E30 rear ends, are known to break sooner or later with 400u drag these cars, with slicks. That's why I'm taking care of it. If somehting blow up, like the diff or driveshafts, it will be time to upgrade to something bigger.

i thought ou have been quoting 458 or something lie that for years now.... since when have you ran with 620? not being a dick, just curious.

~620bhp = ~460rwhp....


but it still managed same traps and et's as cars quoting over 600rwhp :dunno

Good work , It looks like they are make from driveshaft ... I am thinking of upgraiding my rear because I brake something in every second 1/4mile run , today will check what exploded in diff last weekend :(

That's right, drive shafts fromt he 4x4 transfercase and stock halfshafts ends. :)

Would you guys be interested in a super clean and strong solution for halfshafts? We had to have some custom made for our E90 World Challenge cars because I kept snapping them on the standing starts (with only about 300 Hp!). The new pieces we made are a shaft replacement only using the very solid BMW CV ends. The manufacturer that made them for us guarantees them not to break! Email me if interested and I will do more research on production runs.

You can add me to list...I would definately be interested. The car is an e36 m3.

Why did you use the constant velocity on one side and not the other. Both sides have the same deflection angles. A single u joint would have been lighter and stronger. Corvettes use only a u joint at both ends. That is a lot more mass to get moving. Sorry don't mean to crap on your thread ,just wanted to see your theory on the shafts. You had them weld the ends to stock axle ends correct? I wish you luck . ///J.T.///

diegom6
08-15-2006, 02:50 PM
They are welded in both sides and inside, strongest weld you can find out there:)

I had these driveshafts like that. Iwanted fully articulation, that's why I leaved liek that. You are correct, i could went with just two u-joints but I didn't want to mess upcutting these ones.

If I make any other set, I could make it with just two u-joints. And no, single u-joint shouldn't be stronger than two.

468 rwhp = 620 bhp

sorry to keep going off topic but...

.... wouldnt that mean over a 30% drivetrain loss??

18% loss would come out to be about 550.....where are you getting 620?





also, how much would a pair of these shafts run for an e36 m3? may be interested in the future..

Will work on it. The ones we are using are made from 300M solid steel, not rifle drilled.

Besides the shaft the cages in the CV joints that retain the balls is probably the next weakest link. We can make chromoly versions of these cages that increases the strength dramatically.

Just depends how far you guys want/need to go. Everything would be interchangable - you can do shafts first, then cages if needed.

Sorry mate, but the weak point on E30 driveshafts are the splines. Itīs there they snap off:(

It depends on what dyno machine you use. Stock S50B32 engines dyno between 220-240 rwhp on Dyno Dynamics. They are rated at 321 bhp as you know. You can do the maths as easily as me.

But you know what? Horsepower numbers don't interest me much. My car weighed 3107 lbs and trapped at 136+ MPH. That's all you need to know.

You mean the "driveshaft" or the halfshafts? I have seen many blown halshafts in turbo e30's.

Splines in the shaft (that is where the E90 breaks) or splines in the outer knuckle assembly?

For all wanting custom half shafts....
As some of you know I worked with a company and have 1000hp axles and upgraded internals(they have already been tested on there axle machine)
The axles are done but we want to test them on my new set up
before released to the puplic this company does nothing but axles and drive shafts and has a great warranty.Most of you should know who they are.They also are almost finished with the drive shaft one piece for high Hp bmws.These axles will only fit e36 m3. Motor sport recycling and Ics should have these in the next couple weeks

I ment halfshafts, sorry.

They snaps at the splines thru the wheel bearings.

You are forgiven mate:D

I see, well, when times comes to change it, somethign will come up in my head and we will see in what it ends.

Lastly I'm thinking anything is possible if you have the balls to do it. lol

Yes but the BMW modding community is further back the R&D timeline. The VW and Audi community is light years behind the small block Chev guys.

Im trying to catch us up heavy duty Axles driveshaft and a automatic trans adaptor.The only time I miss my big block chevys is when I take off on green
I hate pussy footin on the start.AAhhhh but soon I should be able to rev and dump.I will be stoked when I actually pull a 1.3 1.4 60 foot in the Lil 2.8

Sorry to resurrect thread but I was just talking about this with MPD47 and we are wondering if the rear struts fit with the custom shafts installed.

Mostly under compression is where I'm interested in clearences. Also, have you had any issues with odd angles causing the u joints to bind?

468 rwhp = 620 bhp

So you figure a 25% loss due to the drivetrain ? Sorry for being O T ...:confused I still get confused on this subject for I have heard from 17% to now 25 % ....:confused

I am not a big fan of dyno sheets because they just lead to arguments that go nowhere.

My M Coupe weighs 3150 lbs and traps at 136 MPH .. you can work out whatever bhp figure you want from your drag race calculator of choice.

Using Dyno Dynamics machines the factor that works for factory horsepower claims is 36%. An E36 M3 with 321 bhp makes 220-240 rwhp on a Dyno Dynamics machine. Since I use Dyno Dynamics to tune my car I use that rough factor in the approximation above. but it really doesn't matter, only trap speed is irrefutable.
