Open Air Element/Cowl hood/4BBL

Hey all, OSS here;

I currently have a Q-jet with an open air element paired up with a 15" K&N filter. I am in the process of aquiring an Turbo Daytona hood, and as we know, that has a 2.5" cowl lift on it. Would it be better to...

1- Leave the open air element on, and the cowl as is..

2- Make some sort of barrier to seal the element off from engine bay air, and seal it off so it can only recieve cold air from the cowl?

Would the CFM decrease be worth the colder air density the engine would gain? cammed/bolt on 305 4bbl

Thanks in advance..Sorry if this is in the wrong section

-OSS

You shouldnt have a CFM decrease when you seal it up to the cowl, that is unless you do it with a different filter setup. But you should be able to make up a pan that sits around your current open element filter and seals up to the cowl.

Go to google or something and look at how the '69 Camaro had it set up at the factory. Thats the best way to do it. See the foam 'wall' around the air cleaner base? That seals to a hole in the hood the same size, and the air filter and lid (two in this pic) are free to breathe that way, as they are considerably smaller than the opening in the hood.

Exactly what i was trying to descibe, except picture it with a big open element filter!


Edit:

Heres a pic of a 80 camaro cowl induction setup. Not the best pic...

Ah I can kinda see...looks like a snorkle w/o the snorkle lid, and the snorkle part near the firewall is probably cut open more, correct?

Basically its a stock base aircleaner with a open element style lid and some tall foam on the lip of the base to seal up to the hood.

But im sure your probably not going to be using the heat riser so you could ditch the snorkel part...
