Ram Air

Does a Ram Air kit really make any difference??? I've heard it's only good at high speeds. Any comments?

I've heard what you've heard. 100+mph. At least most of them look good.

Calling it "Ram" Air is really only a marketing ploy. The true benefit at normal driving speeds comes from a large filter area cool air induction instead of sucking air through a straw-like fender hole or hot engine compartment air filter. Weather it be in kit form or home made, get something. It works.

I made a similar device years ago, I just used dry duct. It worked pretty well, but it was poorly constructed. The purpose was to see how well it would aid highway gas mileage. Mine worked by increasing the MPG from about 27-28 to about 30-31, over a 3000 mile road trip...

bad91,

You ram air looks great. Nice work...

Not really because the air is directed in from the bottom...

i used 3.5 i think it is AC tubing... only thing i don't like about it is in summer time your filters get caked with bugs and dirt... i have K&N's so that makes for a lot of cleaning

Thanks! I had the boxes fabricated at a shop. I will be making a few sets out of ABS plastic soon!

Hey Mike,

I'm installing the ram air boxes also and have heard all the debates as to whether or not there is really any performance gain to be seen. I heard that Kevin91Z has taken some air pressure measurements and the results showed an improvement over stock. He also found that leaving the fog lamps in was worse than stock!!!

Anyway, the reason I'm posting is the lip that exists (approx 1" step up) right before incoming air is routed up to filters... see modified pic.

I'm betting that is a source of A LOT of turbulence thus inhibiting the full potential of the modification! I'm taking steps to remedy that and create a smooth transition into the airbox. I'm going to ramp up the bottom of the grill so that it's flush with that lip. I'll post pics when I'm finished if anyone is interested...

Yea, post those pics when your finished! I dont think removing those lips will make any performance difference, but you never know!

I can tell you that the MAT sensor shows a colder air temp reading with the ram-air boxes installed.

I have done a similar modification on my car as well. I left the fog lights in, so the ram is probably not as true. I used aluminum flexible tubing (A/C) and it fit together very easily. As for the bug issue, here is what I did. Inside the round A/C tubing about 3-4 inches before the filters I cut a javex bottle and attached screen door screening with a rubber band. That may sound stupid, but it fits together perfectly and looks and works great. Hope this helps.
