I have a K&N air filter on my Mikuni carb. I get a lot of power but I feel there is not enough air flow to the air filter. Does anyone know what I should do to extend the air intake (i.e. were to get parts for an 84 gls-se etc.) What is a cold air intake. Can I use one on a carburetor converted 13B?

Cold Air Intake is just that, It takes in cold air from outside rather than hot air from inside your engine bay...

The reason is that cold air is more dense...

Let's say for the sake of arguement that 1 lb of air will fit in a 1 gal milk jug... This is at room temperature...

Warm it up to 100-120 deg like inside your engine bay, and you might only get 3/4 lb of air in the same milk jug...

Cool it down to 50 of so deg and you can cram maybe a a pound and a quarter in the same jug...

So... There's a specific mixture of Fuel to air that the engien will run BEST at... For piston engines it's like 14.7 lbs of air to 1 lb of fuel... For the rotary, it's 12 air to 1 fuel... or so... Well, with colder air, you can cram MORE air into the same space... More air means you can mix in MORE fuel... More fuel and air = MORE power...

However since you have a carbed SE, it's probably gonna be a custom job... In fact a lot of CAI's are custom... I'm sure someone can post better ideas, but your best bet is to find a way to pipe air in from the outside, from in front of the radiator...

A good way is to get it through the hood... Remember, due to the areodynamics of cars in general, there's a good high pressure point right in front of the windshield... Hence Cowl induction... Scoops pointed forwards don't do so much for induction...

A lot of this, I've gained from surfing around here... If anyone has any corrections, please let me know.

My suggestion would be to search the archives on this. There are MANY different configs for CAI, and I've seen some pretty good ones in here. They are going to require some modification, but if you want more power then that should go without saying.

This is just one example.
