We just finish the prototypes for the New T1R air intake duct for the DC5 and EP3.

We have had feed-back from customers who have intakes like the Injen CAI which sacrifice a lot of low end and mid-range response.

The duct is designed to "ram" air into the stock air box for CAI and improving throttle response. A good flowing filter like the Spoon drop in is necessary to allow even better gains. The grill is used to deflect air directly into the air box with this design.

Here are some pics:

what is in front of the inlet to the duct?

 

The top part of the radiator.

 

How does this have any sort of ram-air effect on the EP3? When taking apart my stock airbox, that little duct seems to sit right behind the radiator fan. Although a cool idea in my opinion, it doesn't seem to have a practical use...how much more air can be rammed in from behind the bumper/radiator/fan assemblies?

Perhaps if it rerouted the duct to some place where cold/more air would be available, but then that would basically be a cold air intake...

 

i like the concept...this would work great with my gutted out stock intake box with K&N filter...any estimated prices for the intake air duct?

the only problem with this design, like someone stated above, is the fact that it's getting the hot air right behind the radiator...i think that's the reason why Honda placed a 90* bend at the inlet of the stock air intake duct...that and so water won't get "rammed" into the box with the air...late

edit: just reread your post, it'll work with the DC5 Type S

Edit edit: the tubing you use is roughly the same size as the stock air inlet tubing...if there's room, it would be a good idea to increase the tubing size.

Im interested, but I want to see some dyno numbers. The air coming off the radiator, if the radiator is working, would be warm to hot, not cold, right? I'd just like to see that 90degree bend go somewhere better.

 

This duct sits on the highest part for the radiator so you can actually see part of the duct through the grill.

You cannot really dyno this duct cuz if your car is not running on the road , the "ram air" effect does not work with an electric fan. Therefore, the most power out of an item like this is under conditions where the air is forced into the box. Please take a look at the Mugen air box where they have the same sort of inlet.

With the modified box and filter, we are presuming gains to be around 5 hp though.

 

and i ask again...do you have a price for this air ducting yet?

 

We haven't confirm the price yet but estimated prices will be about $100USD.

 

D@@@@@@@MN! i thought you were going to say something like $30 bucks but $100...that's a whole lot of money for a plastic funnel!

i'm hoping the final price will be much lower then your estimated $100USD...late

 

Looking good Are you guys going to make onw which will fit to stock EK box ?

 

wouldnt you need an opening in the grill?

 

Nope you don't have to. This will be a direct bolt-in duct.

Hello,
can you send me in italy five of this T1R air duct(for me and my ctr's friends)??
Do you have the price? and the shipping costs??

Thanks

You've got to prove the performance all the way through the powerband to sell it for that much.

 

you might want to reconsider that price of $100...
"maybe" if it were carbon fiber or some other exotic material (show factor?)...
but a molded piece of black plastic for $100?
I*N*S*A*N*E
realistically, i would be willing to pay $10-15 for a part like this...
otherwise i'd make something better myself...

you asked for our opinions...

 

True...100 dollars is extremely steep for that little funnel type thing with T1R logo printed on it. I realize all modifications are ridiculously priced (for good quality ones anyway) but how much is the profit margin on that thing???

 

Out of curiosity, are you estimating the 5 hp simply because of the ram air effect? If so, that could be a problem. The effects of ram air do not become useful until 80 mph or higher. So basically, there would be nothing but a different sound at lower speeds. Granted, you can probably sell them all day long at $100 because people will think they feel a difference but is there any other advantages to this intake? Does it have a source of fresh, cool air? Is it simply a duct and nothing else? More info please.

 

Dave's got a point, isn't it hardly 1psi of pressure at 90 mph?

 

We are still test fitting to the EP-3 cuz it has tighter engine space. We will probably release them by next month.

IM'ed you

 

With the modified box and filter, we are presuming gains to be around 5 hp though.


Please READ the point that I have made previously.

We have this idea off the Mugen air box and this T1R setup will work similiar. We spent months to develop and testing and do you know how much time it took us to fit properly with the biggest inlet that we can make ? FYI, The duct is made out of FRP (Fiberglass) and Carbon Kevlar version will be available as well.

 

When you say prototyping, do you mean you guys made this? I thought T1R was a company in Japan...or is it an AJ brand?

 

Nice fitment. Will the modified duct work well with the Cwest front bar???

 

IMO i think mugen made their intake for the DC5 this way because it works well in conjunction with their mugen front bumper for the DC5...the Mugen bumper has a cutout right above the radiator for their air intake inlet...

that's how Mugen gets their "ram air" effect...if there's nothing to direct the air into your inlet tube, then all it will be doing is just sucking air like the stock air intake inlet tube...late

Edit: for spelling
