I wonder what load Eloy is running on the drum on his dyno? Most run about 20FTLB's. The guy that does my dyno work has a Dynojet 224xLC and he does a great job for me and people all over the country. On his dyno he figures about 17%. Also I would like to know, if the RAI does make that big of difference on HP how much air pressure they are applying to it?? On a dyno unless you force a lot of air into the inlet of the ram air it will not make any HP difference at all!!??:
Did you know that people have actually taken leaf blowers and forced air into there intake have dynoed a 20HP gain!!
We have a Dyno Dynamics dyno. It doesnt measure hp/tq like the Dynojets do. It doesnt use a big roller like the Dynojet or Mustang, etc. which enables us to dyno bicycles and scooters.

I was talking about it to James, my dyno guy, so he checked the air moving across the MAS and he said it was showing way more then the engine will ever need. adding anything to the system wouldn't make much difference.
In one of my previous posts I mentioned that cutting two 3 or 4 inch holes in the radiator plastic shroud did the same thing as far as cooling and airflow goes and posted pictures of my temp gage as well. (Truth--- about air temps)
One thing I want to say.
I am not trying to knock anybody or scare business away from one of our vender's. I am a facts guy. I just don't want to see people spend a lot of there hard earned money on something either they don't need or doesn't work. Thats all
Remember guys that you are trying to do stuff at home without the same tools/materials as us. You can't always expect to have the same results. If everything we did was something anyone can do at home, we wouldnt be in business. The purpose of our set up for the 2.4 is a ram air affect where on the 2.0, its to give access to cooler air. Both have been tested to work.

Your intake is completely different than mine except for maybe the look of the box. I have two hoses coming up from the next to the fog lamps up to the box. My box is sealed and I am running an RPi filter 6.5"x5.5" base. My turbo is also sucking in air at a different rate than yours is. There are too many things that are different for you to expect to see the same results. It really has nothing at all do with the ram intake put together in this package though so I don't even know why its being discussed.
