ram air

Re: ram air

the ss hood design is so stupid. it looks great but the induction is retarded. it comes in, splits into two big loops around the hood and then finally makes it to the air box. so dumb.

that ramass intake looks kinda cool. i mean ram air ss. but its too ****in expensive.

does anyone have pictures of the underside of the ultra-z hood. it looks like it provides a straight shot to the tb but i cant tell for sure.

Re: ram air

The ram air hood would work if the scoop was moved forward in the hood, like the ferrari 360 modena hood is with the intake inlet in front of the hood providing a straight shot, also the neon srt-4 hood is like this too, but like everyone else has said, it's to motha ****in expensive. I think a hood like the modena hood would look sweet on our cars it would be different from the ss hood but still be pretty sweet, but again it would probally cost a grand just like the ss hood.

for the last time - RAM AIR DOES NOT WORK ON CARS. the normal speeds that cars are capable of do NOT allow actual ram-air to take place.

Also, the Ferrari 360 Modena does not have a hood scoop at all. You're thinking of the 575 Maranello. and even then, it's not ram-air.

Here's the article from Wikipedia:
http://en.wikipedia.org/wiki/Ram-air_intake

Direct quote:

"However, Fluid Dynamics can support claims that only 3 % higher volume of intake air is accomplished at speeds attainable by high performance and race cars (and an intake on the side reduce the volume by 3 %). Forcing a large volume of air into a cone by motion alone is only possible at supersonic speeds (below that it reduces the volume)."

The main thing is that most people assume that "ram-air" systems on cars actually FORCE air into the intake. This is not true. You would need a turbo or supercharger, or a ramjet strapped to your car, to have ACTUAL ram-air, since these systems force air into the engine.

Any horsepower gains from a "ram-air" system on a car are from the colder outside air being drawn in, NOT from air being forced into the intake.

Re: ram air

Just a thought:

The aerodynamics of our cars along with the under air dams only solidify that our cars take air better from underneath. BUT what if someone put something like an SLP CAI on a WS6/SS car; I wonder if it would lower the overall engine temperature even more with two directed blasts of outside air?! Mwaaaaa ha ha ha hah hahahahah! LOL
All of these opinions are very interesting.

To me, it is like a personal experience kind of thing. We have one guy claiming that his dyno proved HP increases over normal HP ratings. My only question to that is, does he know what HIS specific car's HP rating is with and without the Ram Air? Correct me if I'm wrong, but it is pretty regular to see 10 - 20 even 30 HP variations between dynos AND just the cars themselves. Every car that came off the line is slightly different than the ones before and after it. I mean, I've seen two identical, stock f-bodies get dynoed and consistantly come up with different numbers.

If Ram Air works (it does "work" if you consider that it slightly lowers the overall temperature of the engine which is totally different than forced induction) the way GM claims, I'd like to see written proof and numbers to go along with it. I'm interested to see how it is calculated. I am open to the possibility that I am wrong or even partially wrong.

Any takers?

Re: ram air

This was my thinking as well. My plan is to put a CAI to pick up air from underneath and a ram air hood to pick up air from above. I wasn't going to do this for big gains so much as making it pull in cooler air, make it more aestecially pleasing and to lighten it up a bit.
I'll just put the manufacturers sticker on the hood and that will ensure the 20hp gain. Sticker mods all the way, cheap and easy.

Re: ram air

Take the air dam off the bottom of your car and then tell me there isn't a benefit to directing airflow to where it is needed. Depending on how restrictive the stock intake system is, adding ram-air can improve the VE of the engine. I'll agree that the term "ram-air" is somewhat of a misnomer, but "high-pressure directed cold air intake system" wouldn't fit on the hood.

That sounds like somethign from back to the future. That should work great with my flux capacitor once I get that installed. :excited: I got a plan now. Fastest N/A Camaro in the works.

Re: ram air

This is why I never bothered to actually get the "ram-air" airbox for my SS hood. Right now the SS hood acts as more of a engine cooler then anything else which is good for hot Florida. Under highway driving my engine temps are pretty dang low as in they barely lift off the start of the temp guage and this is with 90-95* weather. I enjoy the look of it more then anything else.

Re: ram air

I believe that funkz is right, because although the hood is not "ramming" air into the intake it is making it easier for the car to take in more cooler air than a conventional intake, and this again would only be if the ss hood was a straight shot to the filter, but saying that it would have no effect on the engine would be just like saying, put your intake in a sealed box with one slit in it and it will perform the same way. When the engine will have to suck for air in order to fill the cylinders, if anything i would say ram air provides another source for air. Besides if this were not true and ram air did not work then why do people by high-flow intakes, or the slp ram-air kit, that flows more air to the intake. again i know they don't "ram air" that's a super/turbo, but it does provide more cfm's of air to the intake and to the motor, and you can't deny that, because if you take your basic intake flow, and add to it, the add air flow from a direct shot ram air hood, i bet it have a larger air mass at the intake. If not, then maybe i'm wrong. Oh and i wouldn't quote anything from a website, where a two year old can submit corrections to it or info. Just my .02.

^^^^^^^^^^^^^ = cold air intake not ram air.

I did not say it was ram air, just pointing out how it may make a difference in performance, that's all
