BE Bearings - Extra Clearance bearings for BMW S65/S85

[O2ShootTheJ]

Same here

[ixlr8_m3z]

Someone asked if the VAC and BE ARP spec bolts were the same. In the pictures, I noticed one had a 17 on it and the other had a 18 on the head. Does that matter - I don't know. I don't know if that is thread count or length...

Although I am not an official representative of BE Bearings, I did have a little bit to do with the bearings throughout the development and what I will say is that the intention of the bearings was to extend the service life over the OEM bearings and to bring their life expectancy more in line with what one would see in other high performance engines. Since we were successful with bringing clearances on the S65 and S85 in line with industry recommended best practices with the bearing design, I optimistically expect that the bearings will last much longer than OEM bearings.

Testing is currently underway and will be ongoing for some time. Once there is enough data from testing to support it I'm sure BE Bearings will make some claims as to the expected longevity of the bearings.

I don't think anyone that was involved with these bearings wants to make a claim without the data to back it up. With that being said, some of the best and brightest people, engine builders and manufacturers in the industry had a say on the design.

Thank you for your parts in getting these built. If nothing else, the lead and copper will allow us to run blackstone analysis to get an idea of how they're wearing

I was told via email from BE Bearings that the their bearings will be back in stock in July-ish timeframe.

Thanks for the info.
Do you have any thoughts on the fuel dilution theory since some of the S85's in that AutoTalent thread seem to have high fuel levels and on e S65 had very high fuel levels.

Also, how's it going in Fort McMurry after the fires? Hope your home is ok. Scary videos came out of there.

I don't think much of the fuel dilution theory myself. If fuel dilution (ethanol)was the issue then accelerated bearing wear would not be isolated to the S65/S85, it would plague all engines.

Thanks for the concern about us guys up in Fort McMurray. In total just upward of 2400 structures were lost, that is about 11% of the city. Much of the city is un affected but the hard hit areas are quite devastated, three complete subdivisions were nearly wiped out. As for me, my home and vehicles survived without damage so I count myself lucky. Some of my colleagues and friends list their homes and my heart just sinks when thinking what they are going through..... In a way, it actually makes you feel guilty that your place survived knowing people that lost their's.

BE Bearings should be back in stock in about two weeks. They are in the final stages of the TriArmor coating process.

Tell me more about it.

I am doing a quote with VAC and my friend told me to buy specif ARP2000 bolts.

But I am not sure if it comes with them.

High Performance Rod Bearing Kit that includes VAC Coated Rod Bearings and
ARP Rod Bolts, S65

I recently installed a VAC bearing kit with their Proprietary ARP rod bolts. They spec'd 45 ft.lbs. installation torque. Slightly different than others' ARP bolts. Not sure there are any other technical advantages or disadvantages. As far as I understand it, each shop has their own recipe for hardware that combats rod BE distortion with their bearings.

Also....I just ordered more BE bearing/bolts. Looking forward to receiving them once back in stock!

Just curious hypothetically if this,was such an easy fix, what is the thought on why bmw didn't size them this,way already? Any potential downsides

To keep this thread on track, I will refer you to the bearing wiki thread where this topic was discussed. Not trying to dismiss you for asking, but if I try to summarize both sides here, we will get derailed very quickly.

By keeping it short, it all came down to cost. One bearing size eases and speeds up assembly of the engines. There may have been other factors, but that was definitely the biggest. No downsides to this, and testing is ongoing with the BE Bearings as we speak.

Can't wait, just placed an order for your BE bearings and specified arp bolts

[SYT_Shadow]

Where did you buy them from? Which website?

placed my order on Friday! are there really any advantages to the ARP bolts other than easier torque sequence? My tech recommended going with OEM rod bolts

Placed my order


Didn't see the store, only found links to other resellers that were all out of stock. Thanks for the help

Bearings back in Stock. See this thread for details.

There was an interesting situation a few weeks ago. A guy suffered from #1 main bearing failure which in turn took out the #1,5 rod bearings. The rod got so hot it turned blue, but didn't seize on the journal. The BE-ARP bolt was burnt, blue, and bent...but it held. The bolt came off and of course there was carnage underneath. But the bolt held and that's the point.
