    I talked to Jeff Abate last night for the better part of an hour. The knowledge base for POLO's and Emory's over the last 10 years has really grown. I might need a refresh/upgrade in the next year or two. HP numbers are going way up. Here's a dyno sheet on his new 2.5 liter POLO. He has a second engine about done that should make another 10 to 20 hp over this one. That means there is another 35 to 50 hp to gain with a refresh. I'm not alone anymore. There is a nice group of guys out there now that really get it. 80 to 100 pounds less weight with 6 cylinder power.

      Now what. 30 days and 1000 miles away. I need to find a secure place for the car Saturday the 8th close to San Pedro. The other days I'll be in Carpinteria.

      After giving some thought as to what my car actually is, I came up with calling it a 912 SUPER. What's a 912 SUPER? I would say a Porsche 912 powered by a POLO or Emory 2CAM4. Click image for larger version

        Ralph noticed some „over the limit“ tolerances of the casing, hence we had to rethink and reorganize. To continue had not been an option!!

        Finally we found a boxer engine specialized company - for subarus - and had the case halfs machine measured digitally. The manual measurement of Ralph had been verified.

        As a result out of this we do have to cnc grind down the halfs and cnc rebore, in order to have a perfect alignement of the case!

        Case can be seen in the rear and today it had been worked on preparing for the studs to get realignend, too. After this it should be not too far to get it finished.

        enjoy

          I’m glad you caught it. I have a little over 20,000 miles so far and no issues.

            absolutely,

            as the 912 will be driven @ full throttle here in europe it has to be at max. perfection possible.

            Emory uses a different engine design and is produced more refined than Dean‘s unit, no?

            only in german, but I think you understand by looking at it… larger drilling for slightly larger pins ->reallignment of engine halfs, bearing alley rebore after this..

          All I can say is I’ve hammered over Colorado passes for 10 years and the engine runs great.
          I don't think the design is all that different if it's Porsche based which it is. Maybe he has tighter tolerances? I've talked to several of the 912 POLO guys and they seem to be happy campers. What Dean has built considering his limited resources and Emory's vast scale is amazing.
          The builder of a second version always has the advantage of learning from studding the first version.
          A few Porsche sites is as close to social media as I get. I would rather go and do something.
