Having fitted an after market air filter I finally got around to making a cold air feed/heat shield for it this week and fitted it today. It's secured on the chassis by the self drilling screws shown and a short bracket fastened to the oil filter housing clamp by a small fuel pump mounting from a Renault ( shhh don't tell anyone) to stop vibration. An upper section may be added or the side extended upwards to meet the underside of the bonnet.
nice and easy to work with, would you think of putting a top on it? ie box it off from the engine side
That may be the thing to do Dave, I've got enough alloy left and a couple more rubber bobbins too. I'm road testing it to a meet tomorrow so will see how it goes.
id say if you have the materials then do it, it makes more sense, there will be still a lot of hot air getting over the top as hot air rises but is then kept down by the hood
Will do Brian, BTW I've just watched your video at Croft That looked like lot's of fun.I like Tim Harvey comes across as a great Guy and I liked him as a driver in the BTCC ,he was a gent ( unlike Matt Neale IMHO ) also a very knowledgeable commentator, like Martin Brundle or even James Hunt.
Where is the cold feed coming from Tony? I considered this on mine, and then thought at the end of the day, if I enclose it, I may as well have left the air box in, and stuck the cone filter in it. But you have more air space on an M44 not to need either, temperature does not fluctuate much, having measured it. The important thing is to ensure that what ever air it sucks in, is replaced by an equal or greater amount, other wise you will lose efficiency. Nice DIY skills btw
the filter without the box is a better option but only if you can get a direct feed, blocking the area off is a plus but the feed as mentioned by Zed is the key
