Well Done! I am still looking for a really good design for the FI cars. The ones proposed so far all seem to have significant drawbacks.

Hi there,

I started with drilling two holes as low and big as possible in the front part of the original plastic filter housing.
From there I will guide fresh air via two flexibles hoses into the air box without changing the original design...

I like the idea with the Thermo-Tec heat shield around the original rubber intake part... and it looks more dangerous too :twisted:

Cheers

Norbert

Heya, Wetminkey. I've just recently come back to the boards after an absence and see you PM'd me quite a while back (a year and a half ago) about head gaskets. I *think* I responded via e-mail but cannot be sure. Sorry for the oversight if I didn't.

I have a 32/36 DFEV, too, but with a tall lunchbox air cleaner. Have you noticed much of a difference with your routed cold air intake? I could run a 4" dryer hose to get cold air to the area but won't be able to seal it off. Wondering if it's even worth the bother...

Cheers,

Yes. The intake from in front of the radiator keeps your carb from sucking in hot air from under the hood, and the cool air (from the front of the car) provides horsepower to an engine at running temp. At speed, the intake provides some positive pressure,...
Greatest advantage of all, is that the filtration area is so much larger, and the replaceable filters are available from any local auto parts store.
I also like the ability to easily vent my crankcase and gas tank (via the charcoal filter) to the air cleaner housing. And the air cleaner housing sure makes the 1979 car look pretty original under the hood,...
I think that the ol' "S-shaped" 'snorkel' intake tubes, from the '79 and '80 carb versions, can still be found,...but there are many other ways to plumb a carb's air intake,...!
Best of luck with your car, whatever you decide. Have fun!
Cheers, Todd.

"Thanks much Gus"

Do you happen to know how to get a hold of gus? I bought the kit but need another heat shield.

The shield is a good barrier for header heat. A couple other things I have seen or done. Seen - I have seen one custom snorkel where they took black plastic tubing and routed it from a hole in the air damn up to the cold air intake. Done - Drilled three holes with 2 1/8 inch bimetal whole saw bit in shape of triangle in the panel behind the grill but in front of the air intake to let cold air flow into the engine bay. The cooler intake temps on a warm engine do increase HP a bit.
Buon giro a tutti! - enjoy the ride!
