Racer Chris had one of the HVAC ducts running from front to back. I'm sure he'll dig up a picture for you guys. I remember it looking really cool!

QUOTE(porsche-tom @ Feb 12 2015, 07:21 PM)  air for the engine or intercooler If its for an intercooler, wouldn't be more efficient to go to an air/water intercooler.. the actual "radiator" could be feed off of ducting from the rockers.. They are typically smaller,,, plenty of places to hide.. Ive seen quite a few setups similar to racer chris's and a roof scoop w lexan pieces feeding the engine..So you could see through it!! |

Found it, from 2002...has it been 13 years already...
Painted the same black as the top would hide it quite well with getting the benefit of added cooling air. (IMG:http://www.914world.com/bbs2/uploads_offsite/forums.pelicanparts.com-50-1423859638.1.jpg) |

I carved some scoops out of foam that I was going to cover in CF and mount them on the sail panel. I havent finished them yet.
Just to see if they would work I taped some plastic irrigation pipe to the sail panels and drove around. It worked suprisingly well. Looking at megasquirt readings as I drove my IAT readings would drop by 10*. The CHT readings dropped by 5-10* also |

The airfoil in the pic not only cools the engine it also fills in the negative air pressure area behind the passenger compartment letting it slip thru the air better. |

QUOTE(mgp4591 @ Feb 14 2015, 11:25 AM) How about something like that underneath to funnel the air up into the engine compartment? Counterproductive. The top of the engine bay is where the cooling air comes from, and it exits under the car. The top and bottom should be separated by the engine tin. Ducting more air underneath the engine will result in less pressure differential across the cooling fins, so less air flow--so less cooling! There are flaps under the front of the engine bay on later cars; they produce a slightly lower pressure under the car to help pull the air through the engine a little easier to help cooling. --DD |

I'm not thinking air cooled enough... Could work for a water cooled conversion for taking heat off the exhaust tho. (IMG:style_emoticons/default/idea.gif) |

Harold von K / 9146 turbo.
He used 2 of these air scoops from an open-wheel race car of the '70s era. It was exceptionally fast, sounded wicked, sticky and threw flames, but the scoops looked like something at the harbor (IMG:style_emoticons/default/biggrin.gif) The air scoops did work well for engine+intercooler chores. After this car retired its club racing turbo duties...it was returned to its first livery: an original Kremer Bros. built+raced 9146gt . Marty  |

QUOTE(Racer Chris @ Feb 13 2015, 09:43 AM) The well-known black SCCA Kirby 914 had a similar cooling air arrangement. I saw it many years ago when the SCCA Runoffs were held at Road Atlanta. (As I said, many years ago!) It had air intakes at each headlight opening, which were ducted in the front trunk in a Y-configuration, then combined to form a single round duct through the cockpit to the engine bay. The type-4 engine cooling fan had been stripped of its blades, so the cooling air delivered must have been adequate. |

I always thought these scoops like a 904 would work. But if done wrong, the car would rust even faster

This simple air scoop was made from a cabin defroster duct ,some flex tubing and a bracket. Just used on track days to direct some cold air on to the intercooler.
