Post Ram-Air Intake pictures

Ok, I finally got my pictures up on my website. Check out my website first, http://www.geocities.com/imprezarider/ , and then go to my ram air page, http://www.geocities.com/imprezarider/ramair.html , to see pictures of my project. Let me know what you think of the site.

Thanks

Jim

Hmmmmmm... that definetly gets the coldest air possible, but I don't wonder if it is actually fighting a low pressure around the scoop to suck in air. To me, it doesn't seem that scoop is big enough to really catch the air well.

I wonder if the air pressure in the engine compartment in the area you put your ram air intake as good as the area right below the big hood scoop.

I was thinking of taking out the whole stock air intake and putting a simpler ram air system close to the big scoop.. Like a bent 3" aluminum pipe mated to a K&N cone filter..

I would have a coarse screen there to filter out bugs and other debris..

Tim

Edit..

Your idea is not a bad idea at all. The more air pressure you slam into the compartment, the more power you get.. By the way, another idea would be like on the new rally car! Make a funnel with a foam air filter connect directly to the hood scoop! That is ideal for ram air systems.. Maybe use some 3/16" thick aluminum alloy sheet metal and bend it into a funnel.. I don't know.. I'm just a know-it-all engineer..

8complex-

I've heard that the spot where the scoop is is supposed to be a low pressure spot on the car, and I don't know if that is affecting performance or not. The scoop itself is actually larger than I thought it was going to be. It's about an inch tall and about 5 1/2 inches wide.

Samuri-

I was just thinking, wouldn't the foam filter cancel out any perfomance gains from the ram air? Because it has to push through the faom before it can enter the intake system. Then it has to go through the normal filter, or is there only the foam filter?

the low pressure areas is only when you have the 22b vents on thats why they are raised to make the air go up like a wing and pull the air out of the engine compartment...

I have a similar intake using the same scoop a turn3 intake and the tube from a minnam intake on my98 rs be very carefull with the rain because i was sucking in water and you probably will also when you change your air filter... don't worry you will know when you rev limiter fels like it is a 3000rpm thats the water

Bill-

I don't think that I will have a problem with that because it did rain here very hard on Friday. I was driving around for a while, and when I got home that was the first thing that I checked. I took apart the air box, and there was no water at all inside the air box for the engine to suck in.

I figure the way I have it set up the screen will catch the water and cause it to drip straight down, where it lands on the scoop and srips down to the drain hole. I know the drain hole works because I had a big puddle of water right underneath the hole.

I don't know if you looked at the pictures or not, but I'm not using a cone filter, so the water would have to go all the way through to the air box. The hose also slopes up slightly, so that would make it even harder for the water to go up.

well at the time i was using the turn3 intake only with the stock second box and i still got water in but only in a very hard rain and at high rpms. that where i like to keep it.. if your intake works right there will be quite a vacume mine really breathes deep now hey i hope you don't have any problems but i just wanted to warn you... its good to see anouther mrt scoop outthere

Bill-

Thanks for the warning. I'll definatly keep an eye on that...

So nobody wants to comment on my site?

Jim

Edit: Bill, did you get your scoop painted, or just leave it black?

Talking

I doesn't have to be the amsoil foam.. You can make the funnel rectangular to fit a K&N air filter of reasonable size. Also, I did see a foam air filter on the pics of the 2000 Subaru WRC car that was posted some time ago on this forum..

Tim

Edit...

Your site looks great to me! Actually if you are going to document what you did, (it would be a good idea) put in step by step with a list of tools required for each step or set of steps.. Of course this would depend on how you would like the format to be. And of course, be very liberal with the pictures and descriptions.

note to 8complex

I hope I remember my fluid mechanics well from school.. Lets see. The air travels faster on the higher side of the car.. There fore this is the low pressure side of he car.. If the scoop is funneled to piping that decreases in cross-sectional area, this should increase the air pressure going to the engine chanber.

Please do correct me if I'm wrong...

Tim

Edit..

Dammit.. Where is Bernoulli's Equation when you need it?
