Have the 89 rs-lo3 (tbi 305). Been thinking about cold air. Here is what i have come up with. Tell me if you think this could work.

Camaro / firebird dual snorkel air cleaner. Cut it all the way around about one inch lower then the lid. Weld in more metal in the center of the cut to make it taller. Add the second duck work by the right headlight. Add a k&n with the k&n filter/lid. Then put a lid from a 82-84 firebird with the hole in the top. Add a 3" cowl hood. Take the weather striping out from the rear hood seal to help the underhood heat leave.

Just wanted to put this idea out their, and see what you all think? Would the hole on top of the second lid work to pull in cold air with no ducting, doing away with the firebird design, and not just pull in hot air ,even with the weather striping gone? Would the motor some how take in water from rain, or the carwash? Should i keep the idea, and use just a solid outer lid doing away with the one that has a hole on the top? I know now that the screen is a must also with the cowl hood. Thanks for any thoughts. Any other good ideas might help. Maybe my idea is a dumb one? Been reading too much on this to find little info that helps.

Oh hey, I forgot to ask. What area do you think I could have the best luck in?

You're best bet would be to leave the hood gasket and route air from the cowl panel - windshield area - as this is high pressure area and cooler air and alittle cleaner particle wise than off the street surface intake. JMT's..

IMO, the money you would spend on the hood and paint, etc. would far out weigh the increase in power you would get. If you want more power, do you run headers and a good sized dual exhaust system with an "X" pipe?

For a 3rd gen specific issue use the 3rd gen forum, for a general performance issue use the Performance forum. Mechanical engine problem use the Engine forum... Since you are asking about setting up a cold air feed on a 3rd gen I would think under your hood would make it fairly 3rd gen specific...

Keep in mind the forums are a bulletin board system not a live chat room. It can take days for enough folks to see and reply before you get the answer you need. It's not designed for you to post and get a reply right away... We do have a great group so often it seems like answers come just like a search engine but don't expect instant answers and you won't be disappointed.

No the car is stock except for a 30 over bore. I am just gathering info so that I have a good plan on paper since the interior is almost done. I do wonder about the x pipe clearance wise. I had a rs in the past that would rub on everything. Ripped the front plastic off on a speed bump & caused it to get hot. The exhaust would also rub, just on normal size speed bumps. Most people recommend that I even put on lowering springs? Dont think Ill be doing that one. So does the x pipe tuck in like the stock one or better? Seen a nice one in Jegs with manual dump's built in for under $200. What a steal, If they would work. What do people think about dumps? Seems like the wing nuts would just weld themself to the stud's. I like the idea of a loud car so as of now if im going x pipe then thats the ticket.

I was thinking about the hood to loose some weight, also I like the look, and need a paint job anyways. Last paint job I did only cost me $60. Looks good still after 3 years. This car though, Im going for some better paint. This will kill a lot of people. lol painted my old mustang gt in the driveway for $60. Turned out real good. Poor people have to do what they can. Helped to that Grandpa was a painter @ General Motors. Handed down his shop tools.

Are you sure that I should leave the hood gasket in? I love the idea of getting rid of the under hood hot air. It is hard to get away from that idea. I think I will just scrap the whole idea of running duct work to the cowl, and just use the duel snorkel alone with the k&n filter & lid trapped in a taller air cleaner, still using the cowl hood to compensate for the taller air cleaner. Sounds like my best bet unless their is some good reason why this set up would fail???

Your next idea of adding dual snorkel up front may not be the best thought.

However, I believe the idea of removing the hood seal to allow heat out won't quite work to let out heat as you think it will. The engine compartment is of lesser pressure than outside the hood when traveling above 40 mph. So, the high pressure pocket at the intersection of the windshield and hood/cowl will force air down through the bottom of the engine compartment.

Now, installing a flat plate underneath the open air cleaner and close off the 'cowl induction' section of the hood, making an enclosed chamber of the air filter with an entrance from the windshield/cowl, will help more than dual snorkel up front.

Good info. I have never thought about making the induction system like that. One concern that comes to mind that I had posted about yesterday, (but got no feed back) was would water be able to enter if the rain comes down? Or would the car wash cause water to enter? Maybe it would be a good idea to cut & bend the section at the bottom of the sheet metal, that way if water does get in then it can run down the firewall.

Most glass hoods just have two small holes for the air to get in. I was thinking about cutting it to make it the full size of the hump. What do you think about that? Hope im not asking you to much questions. As you can tell, im a younger guy eager to learn. I only learned how to work on cars to not get ripped off since I have only been able to get older worn out cars. Its a lot of fun. Have over 12 grand now in tools from the last Four years. Best stuff I have ever bought. Besides my Camaro. lol. I am going to figure out how to add links to show you what I have done to it so far. Some people might like to know how to get where im at right now.

You could add a drain hose(s) to the proposed hood chamber, one in the front if the car has a rake to it. But most of the time, not really a consideration.

If the hood has good frame underneath the top sheet metal, you may just want to cut out the inserts of the opening rather than to remove all of it, this would add strength to the hood.
