Intakes Reviewed: Racing Beat VS K&NII
 

So i decided to change my intake setup from the k&n typhoon 2 W/ Racing Beat air duct to the full Racing Beat intake system.
Opened the box nice packing lots of bubble rap, the instruction were great nice and detailed, the actual box was kinda cheap (scratches real easy) but real nice looking, instructions says bout 1hr but since i have the Racing Beat air duct install it only took about 15min.
With the Racing Beat on I start the car up, rev it up alittle first thing i notice that i lost the grunt that the K&NII gives, I expected that but did not expect to notice it gone with all my mods, but suprisingly it was gone.
The K&NII on the other hand sounds great w/intake header, and exhaust gave much more rasp(extra grunt).

So driving with the full Racing Beat intake setup and i notice, idle was no different from the k&n, seem like the rpms would not go up as fast as the K&NII, acceleration felt a bit slower, and on the freeway 4th gear about 80mph floored, top end did not seem as great took abit longer than im used to to about 120mph.1st, 2nd ,and 3rd gear with the K&NII W/Racing Beat air duct setup i was also able to loose traction when shifting and felt a nice pull back when flooring on a roll, but with the rb setup the car just didnt do that, car didnt feel as quick.

Overall on the Revi the price is alittle steep, but real nice product looks great if your into that stock look and want no intake sound and more exhaust sound.....but between the two, K&NII w/Racing Beat duct felt alot better than the full Racing Beat setup.
In the end i end up putting the K&N typhoon 2 back on and got back all the missing pull, sold the Racing Beat Revi.
For what its worth the rb revi also weighs more than the k&n.

LoL Maybe the lack of noise was causing the horse power loss Gil :P

at most you are talking about 2 to 5 hp at any given point. gas or temp could change more than that.. btw the ecu reset, makes it more moot.

sorry dom.. fail..


beers :beer:

It's all in your head. The human body ain't going to feel a 5 hp difference (if there even was that). Your head's playing tricks on you. The K&N is louder, so it must give you more power.

airflow with the revi will be better across the maf than the k&n. you'll get more gains with the cobb accessport if you had stayed with the revi.

yep^

Dyno charts show different.

Revi has more pull through out the range.

It may be 2 hp less only at 8 grand

How often tdo you drive at 8 grand? How long do you keep it there?

Im thinking of Revi, not that I hate my K&N, just want to try something else, you know :)

but hmm another 2-300 bux .... :(

ecu was reseted at all changes, this was done on my car and believe me if i felt a benifit from the revi i would have kept it, and that box i noticed when i drove hard and long the was real hot. overall the k&n w/rb air duct comb felt more responsive even around mid range . btw just cause the revi is a closed box intake doesnt mean you'll get cold air the whole pupose of the box was to reduce intake noise, and that box does get hot.

Plastic isn't a good conductor of heat. It's better the exterior of the intake get hot from the air in the engine bay than sucking that hot air into the engine.

i honestly dout that, have you tried this setup?

but you will still not have the coldest of air.

probably if you are not moving the revi will have better air flow, but i will tell you that when the car is moving the k&n w/rb duct will have the better affect in performance.

What are you talking about? Revi + Air duct is fine.

Having a short intake filter in the engine bay is useless. There's a reason why one of the first mods people do with FI is a cold air intake by getting the filter out of the engine bay.

At highway speeds the air in the engine bay is the same as ambient. Even without the air duct.

You want the smoothest airflow over the MAF. The OEM air box isn't a restriction to begin with, so how you expect another filter to give you noticeable gains over it is a good question.

at high speeds the hot air is not just going to linger there.

never said there was anything wrong with it. i was just posting and informing by experience. this is what i got with a couple of weeks with the revi. its a great intake i just noticed that the car felt a bit more reponsive with the k&n and rb duct.

You're short sighted. Your car is not always in motion. If you sit around at a traffic light then punch the throttle, your intake air is going to be close to 180 degrees. This can mean problems if you have serious horse power.

Moreso if you're on a track and there aren't a lot of straights.

^^^^ i know that but when your racing are you stopped?

im not talking bout on the stop, my experience with both intake setups was on the move, i was not trying to calculate how hot the air near the engine gets at a stop, im talking bout the on the move the k&n w/the rb duct felt better, than the revi.

You aren't reading what I'm saying. So it's not worth trying to explain it a second time to you.

what are you trying to say then???? you were just saying something bout 180 deg at a stop, then you puch it the air is not going to be cold, i know that.

my car is loud to begin with.

I'm saying that the car is not always moving at 70 mph. When you travel slower, heat isn't fully evacuated from the engine bay and can still build up.

yeah its amazing how you got 5hp out of this. where did you read this?
