nose cooling opening

[straubcpeaknet.net]

Does anyone have a CSR nose with the opening in the top of the nose for cooling that is willing to make a template and send it to me. Lookng to modify my current nose.

 

Thanks in advance,

Remember that the CSR is the same nose as the SV - ie wider than the standard one.

I have a feeling the hole was cut using the "that looks nice" method rather than the extensive wind tunnel research.

I do hope that the hole was cut using the "It needs to be here and this should be effective and about right". If, later they said "That looks nice", I do hope someone could repy "It works too!"

Craig, I for one an not convinced about the functionality of this feature. I think it is located forward of the standard radiator position and therefore lets air out of the engine bay before it has passed through, and cooled, the rad.

It does look nice though.

the CSR rad is located further forward than the SV

 

The rad hole should reduce front end lift by reducing the flow of air into the engine bay .

 

The car and mods were tested in MIRA wind tunnel .

 

other bits that didnt make production include, front wing , enclosed roll cage, side pods and rear defuser .

And from the experience of CSR owners it seems likely that venting the air up through the nose cone may cause problems of excess heatsoak into the cockpit due to lack of airflow through the engine bay.

Actually using a wind tunnel whats wrong with testing on the caterham bypass with some duct tape and some bits of wool.

 

The Swiss turbo cars had a bit of mesh bonded into the nose cone to aid cooling, I believe it worked.

I have been wanting to hack about an old nose cone with a vent but only duct half the air up through it leaving half the air to flow through the engine bay, There is even an argument for ducting some air around the radiator and into the engine bay. To cool the engine ancilliaries and footwells.

What would be interesting is seeing how much of that valid area of nosecone is negative (or low) pressure including the sides of the nosecone.

If we can't get a NACA duct design for the rear of the bonnet then I'm going to make an Elise type duct at the rear edge of the nose cone and fit a cover underneath to get (more) air stream through the rad.

 

Problem is it won't be scientific just try to copy the Elise duct.

 

By the way, the Elise duct is so effective that when at a standstill in traffic and the temp gets upto 100 moving the car at a walking pace will drop the temp 30 secs later. (not just coolant circulation as I always blip the throttle to keep circulation going)

Norm,

 

I am not sure a NACA duct will be the ideal solution with knowing the complex air flow over the car.

If there is a pressure build up, surely a vented bonnet, will allow ait to escape, without having to graft in a NACA duct.

 

My Aerodynamicist friend is currently off on his hols, so I can't get a good answer.
