K&N V.2 Typhoon intake with racing beat duct?

I know people have claimed that this is possible, but i have not seen anyone who has actually attached the racing beat duct to the K&N typhoon intake. Can someone please let me know if you have done this, and please post any video or sound clips. Thanks for your help. Oh, and i tried searching but most of the treads went off topic and no one really discussed the duct being added to the intake and how it would be done.

i have this combo...

-the k&n remains an open box, so it still sucks up hot ambient air. the duct just helps bring in cooler air from outside.

-i installed these seperately... first the k&n typhoon2, then the rb duct about a year after. the addition of the duct only added a bit of better response at the upper rpm range. it goes completely unnoticed at lower rpm's.

-i also cut apart my vfad to get a better seal b/w the stock airbox undertray (which is kept in place) and the rb duct.

-bypass the coolant from the throttle body and you're good to go...

I am thinking of purchasing a K&N typhoon cold air intake and I was wondering if it is worth the money? I cannot find one for cheaper than 246. Does it actually increase horsepower and make better gas milleage to a point that it is worth the money?? Thanks for the help

no air intake regardless what company makes it is going to give you substantial power... I have ordered my v.2 k&n soley because I heard the sound of one and I really liked it. If I gain 1whp then cool, but that's not what I'm going in and spending 250+ for.

Some people still think an intake will give them 5+whp. It's just kinda funny realizing it will never change, and listening to them claim after their i/e/h they are now pushing 220 whp on their 8's hahha too good. The sound really is nice though, verrrrry aggressive.

I think 5 hp is very possible peak with the K&Nv2. You also have to factor in that a car isn't moving on a dyno. A few fans aren't going to cool a car the same as 50-120mph winds.

Side note I'd pimp that Del-Sol ,turbo,dohc with pegs and shocks. Lucky!

Perhaps, I'm guessing I have another test in order then, since I will be receiving my v.2 intake on the 31st. We'll see if it actually helps or not.

I put a boost gauge on my sealed REVi, at 70mph+ there is no vacuum. I took it up to 90 ish and it seemed to hold at 0, might have been slightly positive or negative because its just a regular boost gauge that I was measuring it with.

BTW, I hooked into after the throttle body, so those are actual readings.

probably 12-16lbs for the REvi, less of a loss for an intake made of more metal. Removing the VFAD of course.

VFAD stands for Variable Fresh Air Duct

it's basically the same as the ram air duct, located under the black plastic 'diverter' panel right next to the bumper (when under the hood).
it flows the intake air into the stock intake like the ram air duct, but reduces noise through its long piping as well. it's removed when the revi intake is installed (whether or not the ram air duct is used).

I was thinking about getting the revi however most people do not know that it is not legal for road use in california, which becomes a problem during smog. It even states on the racing beat website that it is for racing vehicle only and not to be used on highways. Also, i have read that the k&n has a louder and nicer sound to it which is why i wanted it. So back to my original question, does anyone have a sound or video clip of the k&n v.2 intake with the racing beat ram air duct? Is it worth purchasing the ram air duct?

The one I heard was on a Toyota Tundra, not a RX8 and it sounded a lot louder than stock. His engine was not heard at all until he bought the K&N intake, and now its really loud...I dont know if it will be the same for Rx8, hope that helps

The K&N2 is super light, and is suppose to offer more top end(to go with my flash)

The stock airbox is 1 heavy ****. When you pop open the stock air box you;ll see hundreds (guess) of rows of plastic.(supports?) Those add alot of weight to the box. I'm guessing its to keep the box from sagging under all the heat.
