how many cobras run foot well vents

[400TT]

We provide driver and passenger footwell vents as a standard on PACE 427. We force feed the air from the radiator opening as per the original cars. We get plenty of air even at slow speed using this method.

From memory you are running yours off the brake ducts. We have never had much success doing that and use the brake ducts for what they are intended, force fresh air onto the brakes.

It won't matter where you position the air blowing into the footwell, it is all about circulating the air through the entire cockpit. Keep your hose bends to a minimum, use as large a hose diameter as possible, 2" at a minimum, preferably 3". And insulate the hose against the heat e.g. rising heat from exhaust etc. Also make sure you have some way to control the air flow, especially useful to be able to cut off airflow during winter.

While I agree with Craig that force-fed air through a large diameter hose is the ideal way to go, I have 2" diameter pipes running from the brake air inlets, with the inlets fully covered by a funnel so that all air is directed into the pipes.

Originally the footwells became very hot in the summer. The pipes duct sufficient air so that the footwells are neither cold in winter nor hot in summer. It's a nice neutral feel down there now, with the piped air gently displacing any built-up hot air, rather than providing a forced blast. The system could be more effective with larger pipes I suppose but for an inexpensive solution to having scorched feet during Queensland's summer months, I'm happy with what I have.
