You could do away with the cap on the actual radiatior if you put one of these in the top hose:
We use these on Cobra’s because the radiator is laid down at about a 45deg angle.
Thankyou for that that a great idea. We’ll stick with one cap and have a airbleed valve on the tank. Having been to loads of scrap yards we cannot find a decent metal rad cap with fitting(ie top of an old rad) plenty of plastic ones so if someone has one it would be greatfully recieved.
Metal ones are cheap as chips brand new. You just need to find a race shop in the UK that would have them. DemonTweeks springs to mind.
You may even be able to get one donated & even fabricated specifically if you ask the right people. The idea is to aim high & start at the top. With that in mind I’d be calling around to McLaren, Lola, March & all the Formula 1 teams. Never be afraid to ask & the fact that this is a Spit should garantee that people wil fall over themselves to help.
Look here for a general idea:

This thing is about 10quid:
& thats billet, the others are even cheaper…
& when ya get totally desperate, theres a scrap yard near Mildenhall full of American cars that have radiators that resemble something from a Foden
Wait! Find a Commercial vehicle scrap yard & grab a smashed radiator from a wrecked big rig. Sorted!!
I’d still call McLaren tho……:cool:
