yes, but in order for that to work, you will *need* air to flow under the car. if you don't have any air under the car, no turbulence under the engine, no additional cooling ... the plastic "flaps" that were added on later cars help sucking hot air out from under the engine, but in order for them to work, there has to a some air-flow. running a big-ass front air-dam will not allow any air under the car and your engine temps go up!

Really Andy it would be impossible to keep air from under the car. I think you are exagerating the issue, since all race cars use air dams. Any way I am venting through the hood, with a spoiler, maybe splitter. I am confident, I will be better off than none of the above, and stock air flow under the car, when it ran too hot.
What are you using for cooling, air dam, etc? |

i'm talking 914-4 in particular, not just any racecar. yes, there will always be *some* air under the car, but with a T4 in a 914 and a air-dam like trekkors, you will see a rise in oiltemps in excess of 40 deg. which on a hot day can be too much. a constant air-flow under our cars for engine cooling is part of the design of the car. a air-dam like trekkors was not. you are right, most race-cars have big air-dams. but they also have big front mounted oil-coolers. guess why that is? because their cars are running too hot ...

My own personal experience..
Once upon a time I ran a flex dam with a very low car. (this was on the black car but way back before it was even a race car, and before I had a front cooler) On the highway, my oil temps would go into the red and I'd have to slow way down or stop for a break. When I switched front spoilers to an LE style and allowed some air to flow under the car the factory cooler was adequate for highway use and my oil temps were manageable... Pretty much exactly what Andy's talking about. Yes on a race car you try to keep air out of there and you provide cooling in another matter... but yes also, that the factory designed the car and the cooling system for some air to flow underneath and if you don't figure out another method to compensate, then you had better go with the factory's method. |
