IMS facebook webpage against Porsche failure

[yelojkt]

I wonder where they got their 20% figure from.

has been posted on the net before. There has never been any scientific basis for it.

Recall that Porsche went through 3 different designs of the IMS trying for a reliable one before they eliminated it so it isn't fair to say they did nothing till they eliminated it.

20% of any make's engines will fail given enough time and miles. So the interesting figure to me is how many failures per year of driving.

If 400 LN IMSR kits have been sold per year against 200k cars on the road, that is a small number. Considering that some of those kits replace good bearings, some replace about-to-fail bearings, and some go into engines because another engine fails or the engine is being rebuilt...the number is pretty small on an actual failures per car per year basis. I don't know how many engines Porsche rebuilds a year but since the inventory has been said to be in the teens, can't be too many. Add in engines reused from totaled cars. And parted out cars.

And consider many of the cars failed for a different reasons...said to be 21 or 22 of them. And are never opened up so they get lumped into the "must be IMS" pile.



We obsess too much...because we love em.

I don't know why everyone gets so caught up in percentages... To create a percentage thats anywhere near accurate an EXACT production number must be known as well as an exact failure number.. Neither of those can even come close to being calculated..

At any rate, I saw the FB page and it reminded me that I needed to start one for Flat 6, so i am working on that now.. It'll give a good place for us to post updates as they occur and host the pics we want to share quickly.. I'll be uploading pics all damn day now!

So true. Thus I stated "I wonder where they got their 20% from?" There is no way anyone could possibly know any numbers. But that doesn't stop them from stating it as a matter-of-fact.

20% LOL. I bet it's closer to 2%. Porsche produced about 250,000 986's alone. If it was anywhere near 20% there would be 100 new posts on here everyday from people with actual failures and Porsche would have a serious problem on their hands. And their Facebook page would have a heck of a lot more than 13 members lol. If people are so damned worried about it either sell the car or take it to Raby. It's pretty simple really.
