Has anyone got any pics of the Caterham (or other style) nose vents?

I would like to get some more hot air out/cold air in to the engine bay if I can.

If I can duct out some of the hot air coming through the rad that would be good.

I thought about a wide duct across the back of the nose, or maybe a couple of NACA's but these would just force more air in and increase the air pressure under the bonnet.

I want to focus on pulling the hot air out and replacing it with cold air if possible. I dont have overheating issues - but the cooler the better IMO.

I already have some slots in the back edge of the bonnet which do let out a lot of the hot air.

Open to suggestions....

The higher power cars have a mesh covered hole in the top of the nosecone and a moulded plastic ducting/scoop behind the radiator to send the hot air out.

Have you seen the pictures of the GTS on the 7-indulgence site? Having been subjected to some of the most pathetically arrogant communication from the firm in question I wouldn't give them my money but it looks effective enough.

This one?



Looks interesting - could probably knock something up similar to that in carbon....

Its all about the carbon, loving the new attitude

I was lucky enough to have a good sniff around a brand spanking new R500. That had an angled and moulded piece of plastic behind the rad to duct the air straight out of the top of the nose cone. Muchness the same as the 7-indulgence one.

Mind you the guy come in after 10 mins of his first session. His water pump had stopped working and boiled the water off! £30k car that looked like a steam engine. He was not happy at all.

Nicked off the Scottish KitCar Club site.

Just did it on mine. Would've been nice to get a small lip at the front edge, but that would've required effort and painting.

Instead I went for the expanded aluminium mesh that the boy racers use for grilles and vents with the openings facing to the rear of the car. Driving slowly, you can feel the extra warmth coming across the bonnet into your face.

Aluminium ducting is built in at about the line of the rear of the nose cone [just behind the worm drive clamp you can see through the mesh] to help air from the radiator up - but I didn't close off the engine bay completely [airflow is still needed to remove heat from the exhaust etc]

Do you run an oil cooler? If so either have
it a couple of mm behind the rad or as far as possible away as you end up with A warm high pressure area.

What about vented wings like on my build thread? Cheap to do and you can make them in carbon

Here is the vented nosecone on my Spyder Silverstone.

Be aware that choosing the ducted nose option on the Westfield means that the nose and radiator become one unit. So if you want to remove the nose cone for whatever reason, you have to drain the coolant and disconnect the radiator.

So perhaps a bit more thought into the design would allow a compromise solution to be made.

Flared side panels are another option.
