Gerwyn,
Very tidy, indeed! Is that some form of heat insulation you have around the heater box(Photo 1)?? What is it and what benefits have you achieved? Did you consider any form of heat shield to try and keep the cockpit cooler?
Cheers!
Robbie,
The 'cooking foil' was already in place when I acquired the car- all I've done is clean it up a tad. It must be readily available though because when we wre thinking of using the heater box as an air collector for the induction side, Mike D said something along the lines of, " If we need to take it all off to have a good look, no problems can always renew it"
I don't seem to get any major problem with cockpit overheating ( well, you wouldn't in Wales, would you!

As to the whole thing generally, it really is a compromise. We tried numerous ways of setting something up- ITG kits, BMC kits etc., removing the heater impellers and using the heater box ( Many thanks to Cereal who came up with a good version of this)
I really am thinking now that next year I'll go over to individual throttle bodies (Jenvey I think)
regards,
