You talking about these puppies? http://www.ebay.com/itm/DUAL-CORE-2-ROW-MO...735&vxp=mtr Ya thats what I am going to use for my A/W Intercooler in my fender. Yep. For a time I had plans for an a/w intercooler in the fender too. Scored a bigger engine instead. |

For the TD I was able to fit the radiator next to the engine. I added a second radiator in the back (RUF oil cooler) where the muffler used to be. The alternator fit with plenty of room on the back side.

Impressive that you were able to make that work! Adding additional cooling in the back makes perfect sense!

QUOTE I want to see more! Is this car running & driving? My project is no where near as ambitious as yours. Hats off.... The secondary radiator is plumbed just like a heater core in the stock application. There is a thermostatic switch mounted to the radiator. The plastic air deflectors were removed from the underside to allow air to flow naturally from bottom to top. The wiring is fairly simple. |

I like it.
As I understand it the diesel runs cooler than petrol, so would this system struggle to keep up with a gas engine? |

I had some help in sizing this radiator a while back and decided i wanted extra capacity as i was thinking of adding AC to the mix and wanted the ability to box the secondary radiator in the winter and duct it so it would work like the original heater with an inline fan. i have since decided on heating the seats and have a small electric heater for defrost. don't need much heat in NC. it would be a guess but i think this setup could manage 200hp with the right air flow and maybe an external oil cooler to help. i am not counting on a diesel engine running cooler. my old benz dt had a radiator at least as big as the gas version |

Not a 914, but I think close enough, went to small car gathering this morning and this Northstar V8 swapped bug was there.
Guy said no cooling issues with the radiator in the middle not too far from the engine. Running rubber scoops up underneath the car. |

I think what might help for any of these type swaps is to stay with an aluminum motor w/aluminum heads.
I was watching a video by a leading tuner of LS1 swaps and he mentioned when they use an aluminum block version of the LS they always run 15 to 20 degrees cooler than the iron block versions. |

Why don't you do it and report back. You don't know until you try. Right?

Why don't you do it and report back. You don't know until you try. Right? I am intrigued by the possibility of adding some kind of skin radiator to the rear trunk hatch. This would be a lot more work than it sounds, but it might be possible to reduce the amount of traditional tube and fin radiator area. Other body additions might include a wing or duck tail. Having two trunks is a great feature, and retaining it is a worth goal. Is it worth giving up high power? On another topic, the air cooled engine cooling fins are usually quite a bit hotter than the fins of a radiator, often 50 to 100 degrees hotter. This reduces the amount fin area needed needed which is important given the limited fin area possible. Air flow is expensive in horsepower terms. As I remember, the 917 fan took 75 horsepower at maximum rpm. |

Aren't there examples of mid-engined sports/supercars with radiators behind the driver?
It could be done, but at the cost of some significant body mods and/or big ass fans and ducting. Funny this topic has been discussed since the 70s. Have we seen a proven successful example yet in a 914? |

Are the radiators in boxters in the front?

Yes. Boxsters have two small ones and boxster S's have a third in the middle hence the small extra opening in the front bumper.
Check out the Neo914 build, he uses those radiators |

Positive pressure is king to cooling.
And there is enough room in the front of the 914 if you want to do it, but you loose the head light buckets and the pop up lights. You could also just do the AIR 934 body and just run them in one or both of the side fenders. I so (IMG:style_emoticons/default/drooley.gif) over that car as a kid. 934 engine in the correct place, full Aluminum roll cage. half a 904 sitting in the background of the VW & Porsche mag article. (IMG:style_emoticons/default/wub.gif) No not so much (IMG:style_emoticons/default/confused24.gif) |

Correct, every water cooled porsche has had the radiator up front. They are however very efficient with radiator design in relation to the front bumper and hiding it well so they allow for as large a trunk as possible. |

Twin side mounted radiators, good enough for a big V8 (IMG:style_emoticons/default/wink.gif)
