Cold air intake?

[Doom's Day Custom]

okay than can some one please prove your opinions in mathematical formula to prove your opinion is correct and not just a guess!!!!!

You first!

Some here would be quite happy to respond.. After you prove your opinion first.

I am putting it together but i am having a problem finding a formula to support the flow of air in the tubing problem ... But 3" tubing has more area to support the flow of air to the cylinders and where the throttle and the mass air flow are both 3" or pretty close and the intake into the mass is restricted down to 2.5"...I know that a cold air intake is better than a hot air intake because the cold air is more dense than hot air which results in more power to the more... The longer tubing the more restriction and the more power to pull the need air to fill each cylinder which results lost in power...

I think your missing the part where the air has to get past the throttle plate, through the intake manifold, through the head and past the valves. That's where the restriction is.

The tubing in front of the throttle body is not an issue. Ford knows what they are doing when it comes to motor design/function.

So you would pay out the nose for what...3 extra horses if that and not shift till 4,000 rpm be fore you "feel" a power increase?? You might as well attatch a 3hp briggs engine to your motor.

Like I said its your truck do what you want to it.

sorry for the blank reply, I just bumped it to a new thread.

i was going to try my 6.5hp honda but i don't think it will mount right...

haha ok lets pretend he did come back and prove his side with a math formula...i would like to see your happy response. or were you hoping there is someone else that could do it.

i personally have a k&n my opinion: if you like it buy it if you hate it then don't. is it worth the money alone? probably not. i believe that a k&n is a good start to future mods. it actually seems to have made my gas mileage a hair better maybe 1 or 2 at the most. i'm getting about 20.5 with my 4.0 ohv on highway. granite mine is actually cold air... (heat shield and a air tube running directly from under my bumper straight into the filter.)

Honestly i believe both sides are half right. k&n has the right idea as long as your willing to spend a little more on some other mods to your engine and on the same note those who claim that the filter does not flow better (just seal your lips to a piece of card board and try to breath and then do it with a t-shirt and tell me what you think.). on the other side yes a stock engine can only take in so much air (making the extra flow useless given that the stock setup actually flows more air than needed) which is a reasonable point. neither side can be proven 100% unless there is about 100,000 test to give a decent theory. oh and ford can only do what the government lets them (cat converter????) so throw any idea that "ford knows how to make it most efficient" out the window.

That might be a valid comparison....if paper filters were made from cardboard. But they're not. I actually have held a paper filter to my face and breathed through it. I could breathe perfectly fine. The filter might as well have not been there.

Exactly. The manifold can run at vacuum of up to 20 inHg when the throttle plates are closed, even at wot the engine still runs at around 5-8 inHg. the intake tube usually will be under similar vacuum to the engine at wot. Look at that dyno sheet there are no significant gains until you reach over 3000 and even then that is measured at wot, in day to day driving there as almost no benefit. Stock rangers have a pretty good intake from the factory, there is no real need to replace them.

haha if you couldn't breath through a paper filter then they wouldn't be using it in a stock intake. i know that they aren't made of cardboard all i'm saying is that you can breath better through cloth material than through paper material

not all cold air intakes suck hot air. i did a lot of research when i bought mine, volant makes one, that is a sealed air box that uses the factory intake snorkel to suck air into the air box. its the only true aftermarket cold air intake on the market for the ford ranger. and i love mine. they are very nice cai systems and they are cheaper than a k&n.

dude you have no idea how encouraging it is to hear of someone on this site bring forth helpful info to a question on aftermarket air filters without bashing the dude who asked the question. i didn't ask the original question but i am gonna say thanks anyway.

Used to just leave air filters off back in the carb days for that sound!

Or flip the breather cap! Man those were the days LOL
