Fun times, really nice job! How about some button head bolts instead of hex? Whats this metal stuff? You are missing out on all the resin fumes, and fiber itchy in your sleeves and hands.

Look at where the the engine air intake is, funny scoop thingy on top center. That maybe influenced decision on hood design? Heading out to garage with beer and stool... thinking...vent hose to fender or bumber area and seal off top of hvac.

Sparky and I are in agreement. I don't have my manual handy, but I seem to remember a routine for adjusting the heater core hot water valve. Maybe yours is not adjusted properly.

Do tell, explain how the radiator experiences latent heat transfer? Wind chill has nothing to do with a radiator. Your analogy is flawed, outright wrong. Also, convert the exit velocity to mass flow and compare to the mass flow entering; then you are comparing apples to apples. It should be...

Get a hot wire type anemometor, most have a hold max setting, some duct tape and some time. This reads velocity and you can measure the cross section area. Depending on how close you are to the fan, you have to account for a non-uniform cross sectional flow profile. With velocity and area you...

I think Billy has already covered the basic optimization of any of these choices, shroud the entrance as best you can (no right angles to flow if possible) and shroud the back of the radiator to the fans (again no faces at right angles to flow). Then seal the hood as best as possible using the...

That's the downside to venting heat just upstream of the HVAC outside air inlet. A similar reason the Mclaren F1 uses those door side vents to exhaust the radiator air flow. Since the engine air intake is centrally located on the roof. Just buck it up, it's a small price to pay for the...

Nope, just increasing flow rate through one path of a heat exchanger (radiator) does not = increased efficiency. I don't know where you keep getting this idea. "Heat Exchangers, selection, ratings, and thermal design" by Sadik Kakac is a good reference. I'd suggest the first four chapters...

Did they reduce the opening or is that referring to the lower splitter lip? Err no, I think they just used what they had and went for best bang for the buck they had to work with. The shape of the hood exit and the carbon thingy under the hood gave them the best return on investment and they...

Yeah, I hear ya buddy. I did a project for my Thermodynamics and Heat Transfer Professor my senior year of my BSME degree, it was on air stream flow control and thermal efficiency of a bench top HVAC experimental device. I had to re-calibrate all the installed data acquisition sensors, then...

Why not add mass to the engine area and keep the weight low while not adding to the over all polar moment of the car? :tongue:

It's not opinion at all sparky, its basic fluid dynamics.. you can perform all the tests in the world, this wont change. yes, some testing to "refine" the package is required, yet the basic physics remain. Radiator efficiency has nothing to do with aerodynamics. A radiator could be mounted...

Errr, no. The reason closing the path works to get better airflow through the radiator is that you are sealing the low pressure zone from the higher pressure from under the car. As speed increases the last thing you want to do is add to the under car pressure from an even higher pressure...

If anyone wants to read the paper that was released from Mitsubishi: Vortex Generator Research Due to the limit on PDF size, had to post it as a link to my google docs. Good Reading. Also of note, the long tufts are meaningless for indicating streamlines. I'll try to dig up some of the SAE...
