First time I heard of this theory... IMS

Theories are like butt holes; everyone has one..........

JFP - I don't have one










A theory that is

LOL, I'll stick with my own theory that things break when they want to be upgraded.

If you replace a part with OEM stock, its just going to have the same problem and fail again.

We have seen many talented innovators on this forum produce upgraded parts that do better than stock in any number of areas.

I suppose carrying this theory to the extreme, we might have upgraded a 986 to the point where it will last forever

We have already seen some with 300,00 miles. Thats 12 times around the earth, or the distance to the moon and half way back.

JFP - some people I know are known to have more than one! LOL

356Guy - I've read that tips have a lower incidence of IMS bearing failure. As far as the higher revs better lubricating a ball bearing based IMS bearing - I'd question that. I remember seeing a Pedro video where he spun an IMS bearing up in oil. At higher RPMs oil is slung out of the bearing and the bearing was shown to be running dry. I won't base a theory on one test, but it sure had me thinking.

I ended up going with Jake Raby's IMS Solution. The permanent nature of the design (it doesn't use ball bearings) made sense to me, plus at higher RPMs there would be increased oil pressure which would better lubricate that type of bearing.

Yeah I saw that demo. I worked in the rotating equipment business for 20 years. Most of the equipment had splash lube bearings which worked very well. Others ran in an oil mist. The bearing needs very little oil. Too much isn't good either. Small amounts of moisture in the oil is a killer too. LN's bearings are open on the exposed side right? They seem to run fine even though the engine was not designed for a splash lube bearing.

ps I'm going to talk myself out of buying a Boxster at this rate

Oil pressure is not what keeps the IMS Solution happy, it is oil volume......

.....is not important.

All that matters is that some of them DO fail.

What difference does it make as to WHY they fail? Does knowing why your heart stopped beating matter if you just replaced it with an artificial heart?

If you are worried about your IMS, just install the IMS Solution from Jake Raby and get busy living.

To be fair this is bad logic.

It's important to know what can be done to prevent the failure to avoid replacing it.

Imagine how much value the m96 cars would go up if a definitive case was proven that your ims should be fine if you don't lug the engine or you don't corner hard to the left with minimal oil or use this certain oil etc etc.

In the case of the heart I think priority one is to see why it fails before we just ask everyone to put an order in for a replacement just in case.

Can't agree more guys.

I would have sold my Boxster in 2013 if not for the IMS bears issue. And, again last month. Several serious buyers expressed concern. That and I priced is so high. 10/10ths had the right idea. Buy it and upgrade it along with some other parts and enjoy it. Now that I have figured out the Boxster is not going anywhere Ill add the solution to it and be done with it. Now the question is when. Now? When the AOS goes out? When the clutch is done? Fortuitously, I don't lose sleep over it. I have other issues in my life for that!
