RAM AIR CAI Available from RM Racing

[slooper]

Hey can we add these guys to the aftermarket guide? I just installed their intake over a week ago and have been more than happy with it. I'm going to keep an eye on them - they're creating a line of rally parts for the Protege. I'm keeping in touch with their sales rep, Jason, and will let you all know as they come out with new stuff.

They're also working on a catback system. What are the best catbacks out there right now? Before I decide to get the RM exhaust, I want to see if it's better than the others.

Thanks!

Do have any pics??

 

[slooper]

I don't have pics of mine yet. This is a pic of the one my friend has installed:

The piping is NOT Home Depot crap - they had to special order it from England because it is super sturdy and they needed to go with something corrigated because the force of air from the air scoop was too great. The hose goes to a scoop that attaches behind the lower grill. I admit, it's not as flashy at the Injen or others, but damn I really noticed a difference and it's the only CAI I've seen that has a Ram Air scoop.

It's not ram air. It's a cheap version of a CAI. But hey, look at that, they are charging more than a normal CAI. What a rip off!

 

[slooper]

well, I can say that the price for the Protege CAI is significantly less than the CAI for the NSX, which is what the link lead to. BTW, thx for posting that link, Gyre.
Ben, what would you want to pay so as not to consider this CAI a "rip off"? Also, calling it a Ram Air was my judgement - RM Racing doesnt call it that. If this is not a "Ram Air" then that's my bad - please explain what a "Ram Air" is so that I can know better in the future.

Thanks!

This product, actually IS the true definition of a "ram air" where the intake is placed in such a position, like on top of the hood or in front under the bumper, so that the foward motion of the car forces air into the engine faster and harder.

 

[Gyre]

I have to wonder about the corrigated hose. Yes it does allow for a near universal fit. It also gives up on any chance of laminar flow. There will be a loss of velocity. I guess it's cheaper than having to create a fitment for every car out there, though.

 

[pingdum]

I agree with that, the resistance will probably negate any benefits of the ram. That's the main problem with the stock intake system. The intake is actually in a good position in front of the engine like that, but the air goes through so many twists and turns and resinators (not to mention the paper filter) that by the time it reaches the throttle body it's calmed to nothing.

What is the price on that?

300 ? are they nutz?

 

[slooper]

the $300 price tag is for the NSX CAI. The cost of the Protege CAI is significantly cheaper.

Also, just a thought, but considering that the piping has to be run through the fender and up through the bumper - from an ease of installation standpoint, wouldn't making the piping chrome or even silicon hose seriously increase the difficulty of installation?

And I remember Jason at RM Racing telling me that they originally had a piece of chrome pipe going down into the wheel well but that the force of air was more than the MAFS could handle so they extended the corrugated piping all the way to the air filter (which is a foam filter - which flows better than paper or gauze) to increase the resistance. But given the amount of air pressure that comes through that scoop, I really can't see the turbulence caused by the corrugation to be enough to completely negate the effect of the air scoop. IMHO

 

[slooper]

OH. BTW. Jason also mentioned to me when I got the CAI that they were considering a CF hood with a scoop/port just above the stock filter box to use in conjunction with this CAI setup. I imagine the corrugated hose would just dissapear and some sort of connection would be made from the filter to the hood. Cool huh?

a ram air has air 'rammed' into the engine from the outside... usually there is no obstructions in the way like a wheel well..... i would not call taht a ram air at all. thats like saying if i put a scopp on my short intake then its a ram air... i wish... a real ram air would be if we changed our hood and put a scoop in it.. that my opinion

 

[Gyre]

But given the amount of air pressure that comes through that scoop, I really can't see the turbulence caused by the corrugation to be enough to completely negate the effect of the air scoop. IMHO

I wasn't saying the effect of the air scoop would be negated. I was just thinking it could be more effective than it is.

The added resistance because of the MAF's limitations, on the other hand, could be negating the effectiveness of the scoop. It sounds like the scoop was working too well, it got too much air, and so they made it get less air so the MAF would not go nuts. That's really a limitation of our car, though, not their fault.

 

[APEXistud]

Hell if that thing was $300 you should have called me first. I would have sold you my Carbon Fiber MHP.

 

[Gyre]

Oh yeah ... anybody make an aftermarket MAF so maybe the ram air could be more effective? Would that require a reprogrammed ECU, piggyback, or stand-alone too?

 

[slooper]

That possible piggyback thing would be good to know - I wonder if RM Racing would have to develop something like that to go in conjunction with the Ram Air Hood? I'll have to ask Jason about that. I'll also find out what they are selling the CAIs for now, Jason mentioned that they had lowered their price a bit since I got mine.

Were can you get just carbon pipe?

 

[slooper]

I agree with that, the resistance will probably negate any benefits of the ram. That's the...

Gyre> my comment regarding negating the benefit of the Ram Air was directed toward pingdum's post.
