So, it appears that the existing cooling system is optimized for the physical envelope of the car and the heat output of the motor. It sounds like Porsche engineering is doing its homework... we would expect no less. <g>

That explains why the X51 needs an add'l radiator; to match its increased output...

Loren, is it possible for one to get a copy of the Technik SIB? Is this something that a layman can purchase from Porsche?

TIA,

That book is primarily for dealerships and 3rd party service folks so I do not why they would not sell it to you. A new book of just the differences is published each year - so you likely want the first year of the new model as well as the year of car.

BTW... Contributing Members at my site (RennTech.org) can read these in the special Contributors Forum area. I am not advertising just telling you where to see them.

Well Loren may not be "advertising" but that's because he's a modest fellow....but from the perspective of someone who routinely visits his forum and uses the DIY photos and write-ups.....I can say that it's a site well worth the price of a meager contribution to get access to all the information contained there. I'm not a very experienced wrench....but I figure I've saved over $1K using the instructional information from the site.

Geeze, I _am_ a CM on RennTech... I guess I never looked past the TSB section. :-)

Thanks, Loren. Agreed with Chuck Jones that RennTech membership is a requirement for all Porsche enthusiasts. Glad to see you here, too...
