K&N vs BMC

[Mr. Busa]

lets hear it

[Doc_Busa]

I did a lot of inquiries on this and it was nearly 100% vote for the BMC race filter. So, that is what I got. In fact, at SH.org, many folks claimed the K&N was WORSE than the factory filter for flow.... I say BMC, but I have no dyno results to prove it, just info from fellow Busa'r's...

[Thinker62]

As an ignorant rider, tell me what the value of a good filter is? How will the bike behave differently with BMC vs stock?

[Mr. Busa]

better air flow to the engine keeping it cool. better gas milage so theres less strugle on the engine, also keeps the power band "fresh"

[STUNNAH]

K&N installed no noticable difference...

[Mr. Busa]

as far as the specs go anyway with the better "air/fuel" mixture

I always liked the BMC before i wnet Turbo. The BMC makes 2 filters for the Busa.

1. Open free flowing for stock
2. Race flow.

the race flow will require some minor adjestments. I used the Free Flow with 4

1:2 HMF pipes, helped to get about 172 hp to the wheels.

What kinda adjustments Ninja Eater? I am running the race filter with a Muzzy full system and a PCII. I really need to get it dyno-tuned... something I am missing?

[Mr. Busa]

Yes, please shed some light on what type of adjustments.

Bought a K&N and got 5mpg more with a stock engine. No complaints

[discreet007]

Just my .02 cents

When I used to hang around the track all the racers swore by the BMC for whatever bikes they ran.

Eeeking every last HP out, I guess the BMC is good for a couple.

[Henryace1]

My question is where can you get a BMC filter.

[Henryace1]

I just got a BMC airfilter off of E-Bay for $51.00 + $8.00 shipping.

[200hp]

On the dyno with some motor work I got no change with K/N, 3 hp with BMC, and 5 hp by removing my air filter and covering the air box.
