I know this had been tried 7+ years ago, I was wondering if since then has anyone done a watercooled conversion and not put the radiator in the front trunk?

So, running an air cooled big 6 gets enough air. Why wouldn't a large 4 get enough with fans?
Inquiring minds want to know. |

Exactly, water is a more efficient medium than air so if that compartment can shed 300hp worth of an air cooled* 3.6 it seems that same space can shed the heat from a 300hp 4 or 6 water cooled motor *anyone have the numbers how much cooling is really done by the oil? |

On the air cooled engines, there is a clear separation between the intake side of the engine and the underside where the hot air is expelled. Without that separation, our aircooled engines would be very short-lived. I have yet to see any watercooled solution that followed the same principal. (IMG:style_emoticons/default/shades.gif) |

(IMG:style_emoticons/default/shades.gif) Adding to this.. the 911 engine uses Mechanical Energy to run a Centrifugal Blower. It moves MEGA cubic feet per minute by sacrificing many horsepower. Estimates are up to 16HP: http://forums.pelicanparts.com/porsche-911...g-fan-cost.html Think about how big a 16HP electric motor is... In a 914, you need brute force to pull the air down and through the engine bay. I think this is the fundamental reason why a front mounted radiator is far more efficient. |
