Since I live in the desert, and I am keeping the a/c for my latest project, I am researching Raby's DTM (down the middle) cooling and FAT Performance's 911 type fan conversion and shroud. The car is already dual carbs so I dont have to worry about clearance over the FI intake tubes.
But, I will also be running a small compressor for the a/c. Initial search tells me the 911 style looks great but doesnt cool any better, and the fit is questionable. DTM should be better cooling, and reviews of the kit for Type 1 or type IV converted Beetles is really good. anyone ever do one of these options in a 914?? |

You don't really need a DTM.. Yes, I re- invented the DTM in 2003 and have used them on hundreds of my engines.. BUT the vast majority of these are conversion applications like 356, and 912... Those cars require an upright cooling system to keep the body from being altered.
If you are making less than 45 HP per cylinder, and have iron cylinders, the DTM in a 914 doesn't make sense. I used them on less than 1% of my 914 engines. Now that everything I build gets Nickies cylinders, I still use stock cooling at 55HP per cylinder. This post has been edited by Jake Raby: Sep 13 2017, 08:59 PM |
