I will soon be joining the long list of Pelicanites that have gone down the 3.6 conversion road. I currently have a 1977 911S that has everything done except for the engine (flares, suspension, seats, Fikses, Big Reds, & spoilers). The 3.6 conversion path seems to be getting worn to a relatively clear state, which is good for the guys doing the upgrade now
Nevertheless, cooling is one question I have about the conversion. I read the archives, and it seems as though the dual cooler setup is somewhat popular. I currently have an RX7 front cooler routed by AN12 fittings/lines. Honestly, it does not cool my stock 2.7 as much as I would like on the track. I would say the average temp is ~230 , which is obviously a bit high.
I spoke to my mechanic, Powertech in Rockaway, NJ, and they recommended using a 935 factory Porsche racing cooler (I believe it is made by Behr). They said they've never seen another cooler perform as well as that one, unfortunately it's a bit over $1k just for the cooler. I assume I will need larger cooling lines, and that adds even more to the upgrade.
Why don't people use the stock 993 oil coolers, as they are sufficient to do the job. Do they simply not fit without front flared fenders? Will they not fit in the front/center location?
I do not want to have any cooling issues on the track, so your input is greatly appreciated.
