ram air?!

[fstfoon]

Has anyone ever done or thought about doing a ram air in the bumper like this....

I like the way your ram air in the fender looks! Looks awsome, but I think that that is a low pressure area and might not function as a ram air. I think im going to try and put my ram air like the pic, but I might put intakes on both fenders like yours no just to look cool but I think they might vent some hot air too. Mabey turn them around? at the least remove the lip on the rear. What do you guys think?

Before you cut up your bumper know this. Quality OEM bumpers are very expensive and difficult to find. Cost? About $1000 for a new OEM piece. Second, do you really think this is going to significantly improve performance? Seems a shame to cut up your truck for so little return.

Yeah and second,

I don't think ram air has nearly as much effect on a forced induction motor as it does over a NA.
The turbo is going to pull the air in from wherever need be at the time it needs it, no point in trying to force air into a compressor that is driven by exhaust.

I think the fender vents supply cool air, more than they pressurize the airbox. Oh yeah and they look cool too. :wink:

What are we lookin' at here Jimmy....besides a slow truck? (j/k)




Is there an intake under there somewhere?[/i]

tests have shown that ram air on a naturally aspirated engine does not becme effective until over 100 mph. It would probably have to be even higher on a forced induction engine. Getting cool air is probably more important than getting a ram air affect.

I wasnt looking for a "ram air" effect from my fender vent, I just wanted cooler air that had no chance of being sucked in from the engine compartment.

Well you all pretty much just said what I found out after doin a little research. Seems well over 100mph before any "ram" effect, plus like you all said not as much with a turbo engine. And the bumper cost, yea I just bought one, got in a wreck about a month ago. I think what I might do is just use the hole the size it is and build an air box mainly for the cold air. Looks like itll be pretty easy since there really isnt anything in that area of engine compartment. Also, you guys think vents on the hood is a good idea to help hot air out of engine bay or on the fenders? The reason I care so much about heat is that I live in Tempe, AZ, we had triple digit temps here for over half the year this year!!!!

Well I have three intake temp gauges I put in to see if my ram air really worked. My filter temps went from 140(sitting) and 110 criusing to right at what temps were outside this summer,say 85deg. My main reason was not to "ram" the air into the motor, but get my temps at the filter down. Anyone who says this is useless should not bypass the egr then. The cooler the air you start out with the more it can be cooled by the intercooler. I can't say it gave me alot of power,but every little bit helps.
After doing this my intake temps would rise 10-15 deg above what they started at compaired to 40-50 deg before,during a 0-100 blast. It was a cheep mod for me and can send pics if anyone want some,uses 2 stock plastic rivits in the front bumper, and a scoop and 2 pieces of formed hose. I am sure someone will flame this, but it worked for me.I am still water/air also.

From the tests I've seen done, ram air does more for a turbo than a n/a motor. Simply beacuse turbos hate restriction so any reduction in in this helps. With that said, would I hack up a sy/ty bumper to get ram air? no way in hell. :lol:

but its never acutally "RAMMING" the air in because the turbo is sucking the air in under boost. it might free up a little stress on the turbo, but not until arround 200mph :lol:

Morgan, would you be willing to block off your cold air intake, swap to a stock style and compare the 2 in the 1/4? im wondering how it affects the power range and ETs. obviously you couldint do it until the track opened again, but it might be a cool experiment.
