Has anyone tried to do a ram air setup on their R. If so, how did you do it, and are their worthwhile gains to your setup??

 

Ram air is worthless unless you're going over 100mph. At that speed you're still only talking around 1% with added drag.

 

That doesn't make sense to me. I just wonder why all of the realtime cars would do it, not to mention all of the ram air firebirds. My friend has a camaro without any type of ram air, and when ever he races any firebird with similar mods and with ram air, he says they always start to pull in third and fourth gear. He has raced a lot of cars like that, and he is convinced that it is the ram air setup. I'm not positive on any of this, but it just seems to make sense that a proper setup would help starting at least around 60 mph.

 

Realtime isnt diong it for the "ram" effect. I think they do it for the cold air and short length of the actual intake tube.

 

ram air will help. but what intake are you running on your R if it's short ram then ram air will make a dramatic difference but if it's CAI i don't think it will help that much but if you want to do it just to get that edge then go to a hardware store and buy 3" tubing and run it right in front of your horn

 

I have mine like Realtime, only different.

It comes in 4" tube from the passenger side high beam headlight, straight into the stock airbox.

Ram air will not work unless you remove the air filter.

 

That's the key right there. The filter takes out all of the pressure you generate by exposing the inlet to the wind speed. A proper setup would direct air from a predetermined sweet spot on the hood (usually) or sometimes the front, and directly into the TB, IM, or whatever your setup might be.

 

hey just curious here, don't mean to sound to stupid but... is putting the filter directly onto the throttle body bad? this should really help out my top end eh?

 

would that even fit?

well lets just say i made it fit, i could imagine it wouldn't be too hard.

 

Chris,

Are you the guy running a skunk2 ecu, rolling on spoon rims and runs low 14s??

If you are i met you like a month ago at sears point i actually ran against you in the 2nd elimination round. I have the black 95 Integra RS I ran a 14.0 while you ran a 14.6, but you proceeded to the next round because i broke.

Regardless if you are the same guy or not, I actually go to school up in santa rosa, srjc. Im from frisco and still cant understand how anyone can live up in santa rosa. Lucky for me after summer school im moving back home woohoo!!!


With regards to ram air intakes, i believe there can be signifcant gains with the proper setup. I do not know how the realtime setups are like, anyone care to share?

The setup i use is a 3in tube coming out of the passenger high beam. I notice to achieve optimum performance heat is a major factor. Be creative in finding ways to keep the air charge cooler.

Ram air will work.... and especially on that CRX... Also the ITR would show some gains above 30MPH. It would be better than stock and just as good if not a little bit better than a cold air intake..... , but don't take my word for it... do it yourself and see.
And if anyone is thinking dyno... you can't accurately test a ram air set up, on a dyno.... the ITR moves a lot of air and would benefit from this type of set up.

"Been there doing that"

 

The only reason firebirds have it is for looks, and for the cold-air effect(or GM engineers are stupid, you pick). Think about it this way. In order for ram air to have any effect, it would have to push air in harder than the negative pressure the piston generates(which is a crap load).

 

I don't know if it would be bad as in hurting the engine, but it would be bad in terms of performance I would think. The air would be warmer there wouldn't it?

 

Are you kidding me? Ram air has no effect? Yes, it does. In the pontiac brochure it states the 5.7 liter v8 produces 310hp in standard form. With Ram induction, the hp jumps to 325 thanks to the Ram air package.

This is through hood scoops but same idea. Ram air does have an effect...at higher speeds.

 

The Title Ram air is just a name. What everybody is referring too is sucking in the air that is in front of u. whether it be from additional piping to the front of your car or just from the hood. You would be sucking in air that is outside of your car totally!!! not in your fender well or under your car. With this set up u will increase horsepower like everybody says. plus it allows your engine to breath better through less restrictions. And i would keep the filter on too it still works. I had this set up for my old LS i took off the lower resoninator and stuck a piece of piping on it and ran it to the front of my car and sucked in air from my grill area. And it made a big boost in power and pulled hard on cold nights.

 

Any reduction in restriction will have a positive effect. Any increase in intake pressure will have a positive effect. While certainly it is difficult to prove how much of a gain these changes will yield, there will be a gain.

Even with an air filter installed, a positively pressurized intake will generate more airflow which will make more power than an unpressurized one.

Sorry to dispute viewpoints which others on here seem passionate about but one really can't argue with physics. Drive even 20 miles an hour and put your hand out the window, palm facing forward. The air pushes against it and tries to push it back. That sort of pressure can do nothing but help... It's poor man's boost.

 

roflmao. Well said.

 

Well, from the post here, and the other research that I have done, I think it will work. I am goint to a test and tune at the drag strip on Wednesday, so I'll see if I can try a couple of runs with ram air, and a couple without. I'll let you guys know.

 

"Drive even 20 miles an hour and put your hand out the window, palm facing forward. The air pushes against it and tries to push it back. That sort of pressure can do nothing but help... "

But you have to compare that pressure to the negative pressure a 11to1 compression ratio piston creates at 8,400 rpm creates. Its enough to suck water up a 3'' aem intake.

This example may work: if you put a fan in the middle of a wind tunel. Lets say the wind tunel pushes the air at 80mph, and then you turn the fan on at its capable of blowing at 20 mph. Whats the speed of the air in front of the fan... 100 or 80? I say its still only 80.

But anyway, I reserve the right to be wrong. The reason GM states higher numbers is probably due to the cold air effect. Same thing that AEM uses to create horsepower.
