should I make a ram air for my stock 85 12A, cause when i take off the filter cap it sound better and it proforms much better

 

why NOT?

 

yes, yes you should!
in fact stop reading and go and do it NOW!!

-cheers

 

thanks guys thats was the first time i get solid anser lol

 

...and don't forget the obligatory pictures when you're finished! =)

Running the car without having the air filter element securely bolted down, though, is dangerous business. You never know what's going to get sucked in to wreak havoc on your carb, rotor housings, or apex seals....

 

My home made fresh air intake was good for about 25 hp at 30 mph,35 at 60mph. Just going by seat of the pants feel and responsiveness. Zoomie

 

I think you need to recalibrate your 'butt-dyno'.

A CAI intake is only going to net you about 1-2hp at full throttle, if that. You may feel that throttle response is better - which it might be - but primarily CAI is good for getting an extra edge of performance. Obviously, you get a better benefit from warmer climates which tend to build and retain higher engine compartment temperatures.

My butt-dyno gives a CAI a max increase of 5hp.

 

longduck where did you get your headlight scoop? i just saw a 2nd gen with the sasme setup and i like it and am interested in doing this.

 

http://www.mariahmotorsports.com/ go to prducts, then to exterior then to 79-85 then scroll down to "headlight cover"

 

Like I said take your factory air filter holder to a vice & drill 1/2 in holes all round in 3 rows. W/ a K&N she breathes much better. Not ram air but better than nothing.

 

about a month ago i noticed the headlight cover with the vent in it for 1st gens. I pulled my 85 gsl-se out of storage this weekend and looked behind the right headlight but it looked sealed off to me (granted I didn't take but 2 seconds to check it). If i'm right then it's pointless to have the intake on the headlight cover because the forced air can't reach the bonez intake I have installed. Someone correct me if i'm wrong but I won't see my car for another week and am interested if the air can actually get through.

 

Im gonna build some kind of different air intake when I get my carb. Ill post pics if its cool.

double post

 

how did you make your intake, I have been looking to do it for a while with pvc or carboard to test it out.

 

Those aren't headlight scoops.

I've got headlight scoops.

You could go out and buy an aftermarket air cleaner too. You will just have to make an adapter for it. They not only flow better, but look better than a stock air cleaner with holes drilled in it. I can make more adapters if there is enough interest and its worth my time. I went to Canadian Tire and got a 10" diameter Daytona/Mr. Gasket chrome air cleaner. Its 2" high and just barely clears the hood. Looks great too. Not too flashy, but gives the engine bay an extra kick of chrome.

 

ah, canadian tire.

 

I cant figure out whats the best way to put nice air by the cleaner, should pipe be run down in front or under the radiator with some sort of scoop?

 

For those thinking that you can't route air through a 1st Gen headlight lid - here's how:


Simple enough once you engineer how you want it to work. The hard part was figuring out how to route the air using the same stock parts so that it would look factory. Once I had the air flow path ready, I started on the fabrication. With it set up this way, you can look up the NACA duct in the headlight lid and see red K&N filter element.

It works great, and in 115 degree heat here in AZ, I think it makes a pretty noticeable difference in my intake air temp.

 

so in other words you cut some sheet metal to be able to route the air through to the airbox

 

The only sheetmetal you need to cut is the formed metal 'lip' right behind the headlight lid that is used to mount the rubber dam. This rubber dam keeps rain and splash water out of the front of the engine compartment, and also keeps airflow smooth across the front panel seam lines.

What I did was cut and pound the center section down to make room for my air piping, then cut the airpipe to fit flush with the rearward-most rotating point of the headlight lid. This creates a clean path of air from the lid NACA duct to the airpipe when the lids are down, and also blocks the passage when the lids are up (i.e., when it's raining, I drive with the headlights on to keep water out of my intake).

Simple job and used all of the stock airpiping and rubber hoses so that it looks normal for the emissions guys. No airbox modifications required, and adds ram-air to the CAI system. HTH,
