Hey Everyone,
When it comes to my 914 I've always wanted to run it in the Sebring Chump Car race. It's a 14 hours torture fest. That kills car regularly. Hell, Sebring kills new cars all the time in HPDE events! Heres the rub, I would exit out of the hood except the I would have to exit before my fuel cell. It's even with the back of the headlights. From what I understand about hood exit is that you want to be near or at the highest point of the hood. Way past my fuel cell. (IMG:style_emoticons/default/stromberg.gif) My first real influence was Kevin Wheeler's red car. That car started me down the rabbit hole and I did the fuel cell shortly after. Always thought that I'd exit the oil cooler as he did (trunk floor). But what about lift? He has some youtube videos of his car at Sebring. It appears to me that lift is not an issue to him. Has anyone done this exit, got into there car, and noticed any lift? Do you think Kevin add that fuel cell to add weight yo the front to plant the car down? (IMG:style_emoticons/default/confused24.gif) I like what Brant and Stu has done too. In and out of the fenders. Is that enough cooler for 14 hours. I'm thinking bigger is better. Mocal has a 20" by 6.5" 65 row cooler I can make fit before the cell. Its expensive, and I don't want to do this again and If it works, (IMG:style_emoticons/default/smilie_pokal.gif) My car current set-up puts the oil temps at 245-260F afters 25 minutes. All help is welcome. Thanks Attached thumbnail(s) |

We had a bit of a cooling issue at WG in May
On the fly, we used a section of garden hose to space the rear mounting of the front trunk pins up about 1.5" Basically, it allowed for a 1.5" gap all along the rear of the front trunk / cowl joint and it worked fine to cut the rad temps down. I can't remember where I heard it, but apparently you want the exit area to be about 1.5 times bigger than the entry area to facilitate a steady flow of air. |

Thats actually a pretty cool idea, pun not intended (IMG:style_emoticons/default/blink.gif) little bit of guessing here... 20x6.5x1.5=195 195/64=3" gap at the rear of the trunk would suffice without chopping anything. I am assuming the back of the trunk lid is about 64 inches and not counting any exhaust out the sides of the trunk. Your certainly not raising the frontal area of the car as the hood has the windshield behind it..... I wonder what fluid dynamics would look like there. |
