So the Fans stick out outside of the wheel well. Any Picture from the Outside of the wheel well

 

NO ,The fans are mounted inside of the upper wheel housing. What you see is the side that faces the wheel. Look at the picture of the complete hood, on the right you can see the fans face out towards the tire. Had this since 2014, only trouble was one fan failed and I replaced it with a 12v 4 in computer fan.

I forgot about that pic, I took it years ago. I've run these vents for over 20 years now and I never really felt lower temps. I don't have a problem with much water getting on the engine. Under the hood the Louvers came with reservoirs that divert the water away from the engine.

 

It should be noted that the c4 air flow design was meant to have the air flow cool the headers. if you have hood vents, during spirited driving, it potentially could reduce cooling of headers, since air would be diverted upward instead of downward across headers. So while vents may reduce under hood temps while at stand still it could result in higher exhaust temps while driving, and reducing performance. If the goal is to reduce under hood temps while at a stand still, Im a firm believer that increasing air flow via push or pull fans, to bring in cool air, would work much better than just allowing the heat to escape by the nature of heat rising. The chimney effect of a chimney or volcano increase airflow, not only because heat rises, but because of the chimney effect that sucks air, just like a header sucks exhaust. Vents alone, ar much less effective. I like AFFC's approach with the side fans. If one were to chose the hood top vent method (like on blue/green car), I bet heat escape could be drastically increased, if it were to be combined with a fan mechanism. For example if a fan was mounted somehow underneith the Vent, to encorage flow in that direction, and pulling cool air from underneith car.. I have a pair of those hood vents, that I planned to eventually install on my 85 supercharger C4 build, before I repainted the car, that got delayed. But my idea was possibly to mount the vent backwards on the driver side (super charger side) so it acted more like a hood scoop, to allow another forced path of cold air down through hood around the supercharger air filter. Doing it that way, would also divert any air not sucked into intake, down over header. ps. the cone air filter sits right under where vent would be, in the space above driver side header.

 

MrBigDee, Beautiful hood you got there. Looks super cool, and Im sure it will be highly functional. Only thing is... On one of my race Vettes, I have a hood that raises about 2" in center to allow room for the carb clearance, since its got a higher than normal intake manifold height (for optimal performance). Car came that way, when I bought it. The problem is that, to get helmet clearance under the roll cage, I had to lower the seat. And with the lowered seat, the taller hood now blocks way to much visibilty of the front corners of my car. That lack of visibilty would surely limit my ability optimally drive the line, and get my wheels as close to the edge of road as possible when appropriate. To solve the problem, I either need to put back the TPI or a much less performing shorter intake, so I can put back a stock hood, or rebuilt the roll cage, with more optimal height. I've chosen to rebuild my roll cage top halo. And eventually, I will also go back to a stock height hood, after making what ever necessary intake mods. So in summary, I love your headlights and vents, but visibility is gonna suck, with that super tall hood in center. TTall hoods can be nice for a drag car or street rod, but not so good for a caged road track car. Maybe OK, for autocross, where a roll cage not needed. Why did you decide on such a tall hood center? Looks like more height than needed for something like a stealthram. What you gonna run under there ?

 

Thanks!
True, it affects the visibility a bit, but it doesn't bother me.
I don't race this, a normal street car.

At the moment I have an SLP intake manifold but in the future I will build a completely new engine with a Stealt Ram intake manifold and now I have enough room to install it.
