Which intakes are you talking about? All of them or anyone in particular?

What about a commerical package such as this one?

The canister one yes. I asked a fellow member on the board who has a 1990 v6 firebird. His has the canister one like the 91-92 Camaros.
I'm pretty certain that he's referring to the dual snorkel setup like the 2.8's had, not the 91-92 Camaro's.

And has anyone taken a look inside the engine bay of a v6 3rd gen? YOU CAN STAND INFRONT OF THE MOTOR!! All this talk about hot under hood air is . ESP if you removed your ac condensor like i did.
The air inside the engine bay is still going to be a lot warmer than outside air no matter how much space there is. Ever put a small heater in a room and leave the window open slightly? It still gets warmer in the room than it is outside the room. Is the air going to be colder than the air that you'd be sucking from the engine bay of a V8? Yes. Colder than the air from outside the car? No. The goal is just to get the coldest air to the engine in the most direct manner...sometimes this involves a few well made trips to Home Depot. V6's need a little imagination to get gains out of them.

Thanks for the support br()bert.

The cold air Idea is funny because the intake plenum is the same as engine temp. You guys don't insolate you pipes from radiator fan air so that point is dead.

If you want "cold" air you need an inter cooler like the h*nda boys use with their turbos that goes in FRONT of the a/c condensor that acts like a heat sink. A HOLE in the bumper piped behind the radiator isn't "cold" air

SLP made a box that upgraded the canister style BUT used the same arm duct that came on the car stock.

he's referring to the dual snorkel
I know and there is a 3rd option. 90-92 Firebirds have the canister which has been shown to be OVERKILL for a v6.

rain or water is not a problem. I drive all year round and have driven in everything. I am sure the engine has suck up plenty of snow rain n ice but I never noticed anything.

In the old days they used water traps for filters. I wouldn't be afraid of water with any system. Unless you go driving in 2foot deep puddles at 90mph. Then good luck with any car or intake.

I have exposed air cleaners on my bike and ran in the rain several times. A little water never hurt anything. Might actually make it faster with an even colder charge.

worrying about rain is almost useless and would be very rare as it would take a bunch of water to stall a car. I pour a tall glass of water down the carb of my Buick all the time. Good for the engine.

You do realize water doesn't compress and the reason you don't want it in the engine in any amount is it can hydraulically bend or brake stuff.

Actually, Gumby's right. In correct amounts, pouring water into a running engine can do wonders for carbon deposits.. internal steam cleaning. It's when you try to suck up too much that the problems start.. running through a puddle isn't likely to be too much. If the standing water level reaches as high as your sealed intake point, though.. that's when the problems start.

The 'pouring water into the intake' question is actually something I use to differentiate between mechanics that know what they're doing and mechanics that think they know everything. Thanks for continuing to prove where you stand, Ryan. If you think about it, a glass of water poured at a rate where 1cc enters a given cylinder per intake stroke, it's just going to bump compression .2-.3:1 ... the idea isn't to use a garden hose.. as Gumby said, a tall glass of water, and pour it in, not dump.

And now that this thread's silly factor is at an all time high... end.

Then head over to the power adder section and tell them turbo guys to stop using water injection.

Dude your just dumb and now on my ignore list. I feel smarter already. Your only reason for being here is to be an *** so enjoy talking to your self.

FYI lots of people pour a glass of water down the carb. It cleans the valves and the engine loves it. It would take a bunch of water to do any damage.
