The Mahle Bearings actually aren't the same... Ive been looking at an alternative bearing as well because i don't have time to swap bearings 5 times to get it right with ACL... the Mahle bearings have the tab to keep from spinning BUT its not a stamp out.. Meaning that the bearing surface is consistent the whole way around. At least on the rod bearings from what ive seen. Might not mean much but im gonna do that with Cosworth Mains as long as i can :-p

The Mahle VC1014 rod bearings were previously Vandervell bearings. The best you can get! If you can get them...

You do know ACL makes Cosworth bearings right?

100% confirmed by me recently.
I have 2 friends that work at Cosworth.

Crystal_Imprezav · 11-12-2011, 12:33 AM

That and the huge shortage in Socal of ACL bearings for Subies was because Cosworth got the last stock from every distributor in Socal when ACL started their backorder from the factories.

maxpowr · 11-12-2011, 12:21 PM

maybe acl/cosworths quality control is not what it needs to be right now. im looking into other options.

my machinist has access to king (israel?), but i will call mahle on monday and get he scoop.

call me silly, but i prefer to buy american, when i can.

bswilmington · 11-12-2011, 01:24 PM

I'm curious to how the factory bearings compare to the aftermarket choices? I know oem is more expensive but is there any other disadvantages than that?

maxpowr · 11-12-2011, 01:33 PM

well from what i found, you have to buy a whole set at like 150$ oem. there are 4 different sizes available i believe. personally i feel subaru spent enough on R&D to know what they are doing. i prefer oem to aftermarket when i can.

Being made by ACL and being checked by cosworth are two totally different things. The Main sets that i have here from ACL take hours to spec properly in the same manner that is described here. The Cosworth Mains i have are genearlly within the .0002 that Team Scream & I accept as usable variance.

I have a few rod bearing sets in stock. The mains are not available just yet (hopefully by spring). I have been pairing these with Cosworth size 1 main bearings to my customers that request the highest quality components

They are made in UK by Vandervell to WRC specification (which is says right on the packaging). While talking to my rep at Mahle motorsports about them I was assured they are manufactured with the highest quality and specs possible. No short cuts taken to save cost what so ever (which is what is causing the main bearing delay).

The rod bearings are about $120 for a set.

No Limit Motorsport · 11-14-2011, 06:44 PM

Oh btw STD size ACL rod bearings just came back in stock so we are good to go on ACL bearings now as well

Crystal_Imprezav · 11-14-2011, 10:06 PM

Hot damn, 120 for a set of rod bearings. They better be perfect for that much!

DSM_Outback · 11-15-2011, 01:45 AM

I've tried two sets of these Mahle Motorsport rod bearings and both were consistent in size for vertical oil clearance and both sets exhibited severe side pinch at the parting line on a set of H beam rods that did not experience any pinch with ACLs.

I was told the main bearing delay was from tooling as the Vandervel (sp?) plant was not tooled up for any flanged bearings.

They can make the main bearings, but at the moment to do so they are VERY expensive ($500ish/set). They have been doing it for race teams.

Come spring they are coming out with a new process for the Subaru mains that will bring cost down.

juanmedina · 11-15-2011, 11:24 AM

I am about to order the parts for my build and I am planning on getting standard main ACLs and .001 oversized kings for the rods. Any recommendations? Maybe get subaru mains?

DSM_Outback · 11-15-2011, 11:36 AM

When doing ACLs I always tell people to buy 3 sets, -.025mm, STD & HX.

That is what i did last time. Bought standard and extra clearance.

I can't believe a main manufacturer can make such inaccurate parts.
ACL FTL !

I think that is sound advice, my king mains should be here this week. I got 2 of the 9 sets of std-x (+.001) mains that were imported, and 2 of the 27 sets of std size mains available.
I will be posting results on a std. size crank ASAP.

They are really nice bearings though. The thrust bearings are a three part bearing that the block has to be machined for. So in reality its even more expensive than just the cost of the bearings.

Good news, please do. If they are good I am getting the standard king mains

We got 7 sets of the kings in as well. I put the first set in today, they came out virtually perfect.

maxpowr · 11-15-2011, 11:01 PM

thats good news.

wrxsubiemod · 11-15-2011, 11:04 PM

That's great to hear. My last 2 sets of ACL were all over the place. Had to put h and hx together just to make it work. New crank and clearances were great. But every bearing I ever used needed at least some massaging to get clearances right.

Hearing about these king bearings being spot on sounds too good to be true lol. Ill need to try a set.

Anyone see an issue of using kings with nitrated OEM crank? Or is there a big differance material wise between acl vs king?
