New 997 engines

Will ask again does anyone have any knowledge of the new engines ie ones with out IMS, I would like to know a little more about them,many thanks Mike Brown :?:

Looks like they have tried to eliminate the problem areas by removing the intermediate shaft, supporting the liners all the way to the top, etc, etc. It will be interesting to see how the direct injection works out, as problems with direct injection Cayennes needing old fashioned de-cokes. I've got the 997 Gen2 Service Information Technik. If you drop me a PM with your email address I'll send you the engine section.

I've only read what you have I expect but the main differences seem to be no IMS (I doubt any of us will miss that) and a closed deck for the liners / head interface rather than the open deck. Ironically this seems to be very similar to the Autofarm/Capricorn long term solution to the liner problem. (which somehow makes me feel better about my sillsleeve engine, if not the cost) Interstingly Richard, there is an article in this months Total 911 on page 29 talking about exhaust sound tuning and explaining that Porsche had to change the tips on the latest DI cars to a design that helped remove ugly soot deposits that were building up on the old tips, so your decoke thought might hold. Only time will tell.
