I have seen the cold air inductions for the camaro's on the site but don't know how to make it work for my transam because the air filter is mounted in a different location I wasnt to know if mounting an Airfilter on the throttlebody itself is effective or if I should design my own cold air imduction SLP has one for about 200$ but thats a bit steep for an intake.what do you guys think. any help would be appreciated thanks

 

I'm in the same boat. I've heard the SLP works great, but not worth the money. I've also heard people say fabricate something yourself. As for the airfilter on the TB, it wont work if you have a MAF, plus, it will draw in alot of hot air.

I wonder, can we fabricate something like the Iroc's. Use their intake set up, and cut holes in the plate where the air filter is connected. Think this could be done?

I was thinking about mounting the throttle body air filter in the location of my current filter. because as you said it would draw hot air if mounted on the throttle body
but what could i mount it on? I would have to find some way to cut the plastic peice that leads to the air filter and mount it on that. I don't have a MAF so thats not an issue. what do you think

 

The Camaro's "dual filters" will not work without alot of "modifications" which makes it not worthwhile. I felt the SLP was a little steep also, so I make my own for about $40 totall.

I bought the stock '88 firebird snorkel that comes off the TB. Then I bought a piece of 3" exhaust and had a bend put in it. I primed, painted and clearcoated it and put a cone filter on the end. Then I took some black plastic and weather strip, and turned the "corner" of the engine bay into its own "box".

Very nice setup. If i had TPI I would be out copying your setup right now GMTECH. Unfortunately i have TBI though, so im going to copy Scauffiels cold air box for the open element. Where did you get the rubber molding you used to close your box in?

 

The black plastic came out of a Buick Park Avenue when OnStar was installed. I was debating on useing that, or the side of a black plastic trash can, but that was readily available for free.

The weatherstrip came from a BMW, but there are tons of different varieties out there. JC Whitney has alot of different styles.

I didn't know (or didn't look) that you had a TBI. When my car was carbed (the same car in the picture), I used HVAC tubing from a Class 8 semi. It looks like dryer duct, but was the diameter that I needed, and mounted my scoop that originaly bolts to the radiator support under the car, and ran the tubing to it.

Im going to copy steves cold air box (http://members.nbci.com/scauffiel/index.htm)
Wich sucks in cold air from the rear of the engine bay, and allows cold air to sit aroundd the open element, and im also going to run some ducting from underneath up into the "box". So basically it will be like a resevoir of cold air for the element to pull from, with cold air coming in from the rear of the engine bay, front of the engine bay, and underneath the car. Cant wait to do this mod...just need to get around to it.

The Camaro air intake wont work on a bird, sorry. I have one and tried to see how it would fit on my TA, and the hood doesnt even come close to closing. And the Camaro inlet isnt that great anyway, it has a narrow slot right past where the filter area is where it has to clear the Camaro hood.

I have some 3" dia ABS plastic on my TA, attached to the MAF and stock air canister. You could use the ABS stuff and run an open element on the end of that, put a hole in the tray and take air in from underneath, or do something like GMTech did. I kinda like that, looks nice. Wheres the battery?

 

The battery is in the stock "LG4" location. 3rdgens have two battery boxes. Pass side for carbed cars, and drivers side for TPI (not sure which side for TBI). I didn't want to relocate my battery to use an SLP, so I did that.

TBI batteries are on the passenger side.

Yep, and the TPI birds have the battery on the driver side... TPI birds are the oddballs, the battery belongs on the other side of the car IMO. Closer to the starter, offsets the weight of the driver, was closer to the alternator before they went to serpentine...

 

will gmtech's idea work with an 88 bird 5.7 maf equiped car? if so i am sold.. u need a patenent my man!!

After experimenting with many sized tubes and scoops. The best system I've come up with is as follows:
This is for a 89 GTA style intake with batter on drives side.
1. Remove the fuel canister, airbox and steel base that supports these two items (3 bolts)
2. Using a die grinder and metal cut-off disk, enlarge the whole that goes out to the fender. You'll have to cut about 2iches across and another 2.5 inches down (stop just before the hole that's used for the base. Now you can run a 4" tube down to the bottom of the car. Connect this tube to the airbox (you'll have to massage the opening a bit to get the 4inch tube to fit on the outside of the opening. Also, cut some windows in the airbox. Now, at the bottom of the car, cut a 4'inch hole and install a scoop. I used an galvanized steel intake vent at the bottom and it works perfect. I also installed a galvanized plate on the top of the plastic so that it can screw in better. Use some 4" ring clamps to clamp it all down. As for the wet stuff, I just stuff a sponge in the scoop so I don't wash the internals of my engine. Sounds good but work great for greater throttle response.

I realize this is really old, but I wanted to ask "GMTech," what to use on the upper radiator hose to subdue some of the heat from heating up the intake air?

Think the Firebird intake bellows flows more than the TPI hardshell where the filters air? Removing the whole assembly on the dyno yeilds 7HP... but that could be filters I guess. (K&N)

Yeah this thread was just a couple decades old

I would try some of that foilback insulation, its a thin layer of insulation with basically tinfoil on th back of it. I think that would work nicely but may or may not look too good...
