Don't know where to place this....but anyway...

While my '92 Formula is immobile with the bumper and both headlights out, I figure now would be a fine time to fab up a cold air intake! First, I'm sure someone has attempted this...mind telling me how exactly you did it?

Here's my idea...find or fab something to fit over the oval throttle body, then buy pre-bent metal tubing like that of mainstream CAIs and have my friend weld them together. Follow stock routing but either find or make a hole to put the filter outside the engine compartment. I may also get some clothesdryer tubing stuff to make a temp, or to get an idea of just how it will work.

Any comments or suggestion?

Thanks! Evan

 

i cut all that plastic crap out from under the air filters, and slid some 8" ac ducts between each filter to each fog light. took out the fog lights cuz they weren't working, but you dont have to do that. noticed a SOTP difference the moment i got on her. might as well get a tb air foil while your doing the cai. click the link below, thats what i based my idea off.

if you want a simple cia...

i'd put some material on the sheetmetal though to reflect heat comming from the a/c compressor though

Check out the pictures on my site, page two, to see what I did, I talk about it on the site too.

 

dj haf, I don't quite understand what you're talking about. It sounds like your Camaro already had dual filters, and all you did was add tubing to where the foglights were. My Firebird is a bit different...it only had a single filter on the passenger side.

I'm basing my idea off of this:


Basically either get an OEM elbow to the throttle body, then tubing, a 90* elbow, more tubing into a hole I'd cut underneat where the stock filter was, then a K&N.

Here's how she stands right now:


Not sucking the coldest air, eh?

Do y'all think 1/5" thick 3" PVC piping will stand the underhood heat? Or should I look for aluminum piping instead?

 

BTW, is there anything else I should consider doing while she has no front? And I mean NO front.....

 

Well, I may not be building an intake after all. I'm getting another daily driver, then start a different project. Possibly a 350 Fiero? or a 350 240sx?

 

Stokdd. Sorry to here about your accident. Your car is so nice.

I bought the TGR CAI and knocked off over two tenths in the quarter mile. It makes a huge difference over the stock setup. Since the front end is removed, you might want to consider a cam swap.

 

Stokdd, GM high tech performance tried a throttle body air filter like you have and lost over two tenths in the quarter, and if I remember correctly, around 13-15 horsepower at the wheels, and that was barely better than the stock routing. The problem with the position of the air filter is that when the hoods closed, the motors sucking in a bunch of hot air off the radiator, and if you have a maf that setup is just not feasable anyway.

 

Do you think as Ram Air II hood would help out in that? I'm looking for a new intake to match my RA II.

 

heres mine, with some stuff youll probably like, that other people added to the post too...

I realize that and it bugs me to death! That's why I'm here.....

 

Yeah a ram air setup with a box and filter positioned at the ram air portion of the hood would work well, but a filter on the tb, is just not the best for performance, it will work, but not the best.

You can look online to find a setup like this for ram air, maf or no maf:

 

and another side view:

I also have pictures of my cold air setup on my site, page two.
