not going to find much, I would do the "ram air" thing, or at least cut the bottom off the stock air boxes

You dont need one. The stock Camaro TPI intake is one of the best setups out there. The best thing you can do it cut out the plastic pieces underneath the air filters to make them fully open.

its funny you say the cutting thing... i didnt even read about it on here i was putting in some filters and i kept diggin deeper i looked at my buddy we just smiled and started cutting stuff haha... would the ram air be more afficiant than stock??

the "ram air" I mentioned involves ducts that go down from the stock air boxes(with bottoms cut off), down to behind the foglight openings

That is contrary to the results most people have come to after back dyno tests, one with the airbox connected and one without. The stock TPI intake is extremely restrictive. Look at how narrow the tiniest part of the "neck" going from the airbox to the TB is. At WOT the "neck" can also be sucked flat.

you would need alot more than 5.7l to suck that hard plastic intake "flat" :D

Ok, maybe not completely flat but a modified 350 can pinch it a little. If you cut one up you can see that the inner diameter is also not nearly as wide as the outer diameter.

point is im trying to find the best way to run my intake system and im still not sure on what to do

stick a filter on the end of the TB.....the stock box is junk


you WILL pick up by just using the filter on the end, I don't want to hear any crap about hot air either......More air is better than less, and air inlet temps are not going to be as much of a difference for the power you gain by having more air.

Yer welcome :D

This is one of the best looking and performing ones,

I should have kept this SLP part since it is now very hard to find.

Is that the one for Firebirds only due to the battery location on a Camaro? Or wait....was it the Firebird that needed to have the battery relocated?

Battery needed to be relocated for both cars since there are airboxes on both battery trays.

Where can i find one of those SLP intakes at now days??

Ebay maybe, they are hard to come by nowadays

does anyone have one??????

Ok, I'll say it. People have done dyno tests with that air filter on the throttle body vs the stock intake. The straight air filter made less power, especially with the hood closed. Although, I cant remember where the post is to back it up.

There's no way that the airbox could be sucked flat. Ive modified mine quite a bit and I know if you push on the plastic too hard (sucked closed for example) it will crack and break.

Ive also tried removing the airbox altogether on the dyno (no filter even) and I lost 5 hp as Kevin91Z has mentioned.

Check out my Cardomain site, page 2 for my airbox mods. I got the idea from MikeH over on TGO. And no, I havent done any dyno testing yet, as I sit here in Iraq.

"stick a filter on the end of the TB.....the stock box is junk"


that's a good idea...unless you have a MAF sensor

maybe make youre own...get a 90* elbow from an LT1, stick your MAF (if equipped) on there and then run some 3" or 3.5" pvc pipe down to a cone filter

I stuck a K&N cone filter in place of the airbox on my Formula

There is a lot of ways to make a custom untake but I think its crazy you could drive a 92 ford pick up and K&N makes an intake for you but not for a 91 z28 just nuts

To get true test results on that you would have to goto a track and compare times. On a dyno the air is static not moving as it will when you drive, which is why a true ram air setup will not provide any gains on a dyno but will when your driving.
EDIT: Your best bet for a CAI would probably be this hood with the matching intake box.

Yer welcome :D

I did that to my car and picked up .2 in the 1/4. Then I went through a big puddle and hydro-locked the engine. :(

well, water should be avoided with that setup

Marc, you are the first person EVER that I've heard say they managed to hydro-lock a running engine.

Looking back I would tend to agree with you. :D

It sucked....big time. When the motor was pulled apart it was not pretty. I think I posted about it after it happened :think: Then again this was many years ago....

I have seen quite a few, rarely do they survive, usually, there is a rod out the side of the block, though if lucky, all that is needed it to pull the plugs and drain the cylinders

I ended up breaking a piston :eek: there were peices of it in the oil pan. :(:cry:

Intakes boys intakes!!!! No one knows of a good intake for a 91! This is a modern mystery. There is one for firebird but you have to relocate your battery to get it to fit but other than that I know of none.

If you need to change it that badly, move the battery to the driver side and install a firebird airbox, or make your own out of some aluminum tubing. Make sure to polish it and use those snazzy blue couplers because they're proven to add up to 10 horsepower each.

Unless you have 400+ horsepower, you're wasting your time replacing the stock camaro airbox.
