"Ram Air" is just a generic term

some people say it works, some say it doesn't.. the fact of the matter is, most induction setups you CAN say are "Ram Air"

Whether it's CAI or not, it doesn't matter. You can still call it Ram Air.

IMO, any routed-system to get more air from the front of the car, with the least amount of bends in piping,etc, whatever can be considered ram air. Just for the fact that more air WILL be coming in, at higher speeds, if it's nearing a straight-shot into the engine.

Is it CAI? Of course. But because the air is setup to come from the front of the car, in an opening, I consider it Ram-Air. Unlike how most people think it's the "Straight-shot of air into the engine".

Either way, more air WILL be getting to your engine. The stock setups are VERY limited, air-wise... and doing the "Ram-Air" setup, will actually get you better performance. The air won't be going 600mph, in a straight shot to the engine, causing a 500hp increase and 500 TQ, or anything.. but you will be getting more performance.

It's all about definition, some have different ones than others.

 

If you go to Home Depot and look in the area of the store that has the heating ducts you might find these things( facsimalies)for about $10,and you don't have to pay shipping.

 

IROC-T,
i looked at my home depot a while back and i tried using 6" flexible heating duct but it didn't work. what exactly are you talking about. Is the name of it "facsimalies" ? and do you have a pic of them? what are they really used for, maybe that can give me an idea.
thanks!

 

They look like some kind of heater ducting,I'm sure that some kind of heat and air company,or Home Depot type store would have something simular that could be used in it's place. They look to me like they are just a square 90* heater duct. As for 6in. ducting I'm sure it would be to big for the area you are working in,3in. would probably work there and would also be more than big enough,you might even try an old shop vac hose,some of those are about 3inches in diameter.

 

You could call it whatever you wanted, its irrelevent. I didnt dispute the fact that the stock setup is restrictive or dispute that you will see gains with an aftermarket setup. All I said is that 'Ram air' is a hoax, you cannot build static air pressure at automobile speeds. If anyone thinks that the car pulls better at highway speeds because they have a scoop in the airstream theyre just kidding themselves. Like I said, just dont pay more money for something because its labeled 'Ram air', get the cheapest CAI you can find (or build one), theyre almost all the same anyway.

 

thank you thank you mr raab himself ladies and gentelmen.
i work heating and a/c and flex duct dosent let air flow as smooth as hard smooth duct because of the amount or restriction in the sides of the flex so we charge more for hard ducting. so my point is the ones from ebay will flow air smoother unless you can make some out of hard ducting yourself i say the ebay is the way to go because working with sheetmetal sucks

 

anyone have any any blueprints to the ram-air boxes? like, all of the dimensions, etc?

 

Not to high jack this thread, but would installed a smooth metal pipe between the air filter and the engine make a difference? Stock (atleast in my firebird) is this ugly rectangular black pipe. I wonder if bending a large pipe would make a difference.

 

redirecting any kinda of cooler air in the tpi is a good idea the tpi motor thrives on air so the point of this thread is just that. any kind of added air will work for you me personally i prefered the premade smooth boxes from ebay if you want to take a whack at the home depot kind go for it it cant hurt can only make it better. maybe its not ramming air into the heads but its ramming cold air thru the filters leaving plenty of cold dense air for the t body to take(its ram air up to the t body.) no complaing ladies

 

got the gist of it
no, it's proven that it can't "ram" air into the engine so to speak, atleast at any car speed you're going to do
but the biggest thing is that it pulls the cold ambient air from the outside, rather than the air from under the hood

just adding more flame to the fire

 

There are plenty of people who have built theyre own CAIs out of smooth ducting. To be frank, the difference in flow isnt that big of a deal in the big picture, I think a lot of people worry too much about airflow before the throttle body and not enough about airflow after it.

 

well your first year with you new f body is not gonna be the year you go ape on the motor after buying the car so we tend to do cheaper more fun stuff till we get the money to dig in like me this year i did all the stuff in my signature and next summer ill have new gears subframe connectors driveshaft and loop and some chrome iroc-z wheels. then next summer after ill rebuild then paint so on and so forth it takes time everybody

 

Ok great... more air into your motor.
But does it even WANT that air? Last time I heard you had to have the proper amount of fuel to go with it.

 

Yes, we want more air.

The TPI setups are restricted like hell, from the factory..
ESPECIALLY the 350 TPI...

if you were to take off your intake setup, whatever (and somehow keeps the MAF sensor intact) you could feel tons more power... now, since you need filters, people just redo their intake setups... Most people seem to be into the CAI / Ram-air thing for Camaros, which gets rid of most of the restrictions of air coming to the throttle body.. you can "feel the car pull harder" and "accelerate quicker"...

some guy once put it a good way something like "It's not that more air is getting forced into the engine, It's that the engine is finally getting enough air to breathe."

Another words: Our stock setups are crap. Just like the exhaust setups are crap (easy 30hp? or something from changing it a bit)

then porting the plenum for the 350TPI helps, too.. since it's the same that the 305 uses, it really doesn't provide enough air.
