in 1,2 gears , torque is very low ... I have to raise the throttle more than P150 when riding through bad roads ... I checked this model in some sites and the costs is 4490 bucks ... Do u knw the price of original filter ...???[/QUOTE]


I really don't know weather the filter will help to increase the low end torque cause in first 2 gears i did not find any difference in the lower rev range its only when cruising at higher speeds around 120kmph you can feel the difference .....with a stock filter at around that speed in 6th gear i never felt like up-shifting cause i was certain the bikes in 6th gear where as now i have that constant feeling the bike's in 5th gear even though its in 6th gear. By the way i got the filter for 4150 after some bargaining.

Price? Does it conflicts with the battery?

Debunking the K&N Myth - Why OEM is Better

For decades, the aftermarket hot rod, racing and tuning communities have relied on oiled-media filters to free up that extra few horsepower. In fact, it's often one of the FIRST modifications many automotive enthusiasts do to their car.

This report shows, with empirical data and sound reasoning, why OEM filters perform better in a variety of areas.

Special thanks to Arlen Spicer and all others involved in making this information available.

A note from the author:

The reason I started this crusade was that I was seeing people spend a lot of money on aftermarket filters based on the word of a salesperson or based on the misleading, incomplete or outright deceiving information printed on boxes and in sales literature. Gentlemen and Ladies, Marketing and the lure of profit is VERY POWERFUL! It is amazing how many people believe that better airflow = more power! Unless you have modifications out the wazoo, a more porous filter will just dirty your oil! Some will say " I have used aftermarket brand X for XXX # years with no problems. The PROBLEM is you spent a chunk of change on a product that not only DID NOT increase your horsepower, but also let in a lot of dirt while doing it! Now how much is a lot? ANY MORE THAN NECESSARY is TOO MUCH!

Others are persuaded by the claims of aftermarket manufacturers that their filters filter dirt "better than any other filter on the market." Sounds very enticing. To small timers like you and me, spending $1500 to test a filter sounds like a lot. But if you were a filter manufacturer and you believed your filter could filter dirt better than any other media on the market, wouldn't you want to prove it? Guess what. Test your filter vs. the OE paper. It will cost you $3000 and for that price you will have the data that you can use in your advertisements. Your investment will be returned a thousand fold! EASIER than shooting fish in a barrel! So why don't these manufacturers do this? Hmmm? Probably not because they would feel guilty about taking more market share.

Now I am not saying that ALL aftermarket filters are useless. A paper filter does not do well if directly wetted or muddy. It may collapse. This is why many off-road filters are foam. It is a compromise between filtering efficiency and protection from a collapsed filter. Now how many of our vehicles collapse their filters from mud and water?

However, if a filter is using "better airflow" as their marketing tool, remember this....Does it flow better? At very high airflow volumes, probably. BUT, our engines CAN'T flow that much air unless super-modified, so what is the point? The stock filter will flow MORE THAN ENOUGH AIR to give you ALL THE HORSEPOWER the engine has to give. And this remains true until the filter is dirty enough to be recognizeable. At that point performance will decline somewhat. Replace the filter and get on with it.

Hopefully the results of this test will do 2 things. Shed some light on the misleading marketing claims of some aftermarket manufacturers and/or give us new insight on products already on the market that are superior to our OE filter.

SCOPE:

This report presents the results of an ISO 5011 test of several air filters designed for the GM Duramax Diesel. The test was independently performed under controlled conditions using a $285,000 machine at Testand Corp of Rhode Island (manufacturer of the machine).

Arlen Spicer, a GM Duramax Diesel owner/enthusiast organized the test. Testand offered to perform the tests at no charge. (These tests typically cost approx $1700.00 per filter). Ken (and employee of Testand), a Diesel enthusiast and owner of a Ford Power Stroke Diesel, shared Arlen’s interest in performing an accurate unbiased test of different types and brands of diesel engine air filters.

The filters used in the test were purchased retail and donated by Arlen and other individual Duramax Diesel owners. The detailed reports from the test have been compiled and are presented in the following pages. The final pages of this report present the behind the test.

ISO 5011 Test:

The ISO 5011 Standard (formerly SAE J726) defines a precise filter test using precision measurements under controlled conditions. Temperature & humidity of the test dust and air used in the test are strictly monitored and controlled. As Arlen learned in attempting his own tests, there are many variables that can adversely affect filter test results. A small temperature change or a small change in humidity can cause the mass of a paper filter to change by several grams.

To obtain an accurate measure of filter efficiency, it’s critical to know the EXACT amount of test dust being fed into the filter during the test. By following the ISO 5011 standard, a filter tested in Germany can be compared directly compared to another filter tested 5 years later in Rhode Island. The ISO 5011 filter test data for each filter is contained in two test reports; Capacity-Efficiency and Flow Restriction.

Capacity and Efficiency:

The Capacity and Efficiency test report presents the test results of feeding an initially clean filter with PTI Course Test Dust (dirt) at a constant rate and airflow. The course test dust has a specific distribution of particle sizes ranging from less than 2.5 microns to greater than 80 microns (see table below).

Every filter is initially tested at 350 CFM and the Initial Restriction or differential pressure across the filter is recorded in IN-H20 (Inches of Water). The filter is then tested by feeding test dust at a nominal rate of 9.8 grams per minute with a constant airflow of 350 CFM. The test is continued until the flow restriction exceeds the Initial Restriction + 10 IN-H20.

At this point the test is terminated and the amount of dust passed through the filter (Accumulative Gain) is measured. Dirt passing through the filter is captured in the Test Station’s Post Filter. The exact amount of dirt passed is determined by measuring the before and after weight of the Post Filter.

Similarly, the amount of dirt retained by the Filter under test - Accumulative Capacity – is measured by taking the difference between the before and after weights of the Filter. From these results the overall % Efficiency of the filter is calculated. This test also indicates how long a Filter will last before replacement is required (or cleaning for reusable filters).

Flow Restriction:

This report presents flow restriction of a clean filter resulting from an increasing airflow. The differential pressure restriction across the filter is reported in inches of water (IN H2O) versus Air Flow in cubic feet per minute CFM.

Data from these reports has been compiled and presented in the following bar graphs, plots and data tables.

Filtering Efficiency:

Filtering efficiency is a measure of the filter's overall ability to capture dirt.



Accumulative Capacity:

“Accumulative Capacity” is a measure of dirt holding/loading capacity before reaching the maximum restriction limit.

Initial Restriction + 10 IN-H20.



Accumulative Gain:

"Accumulative Gain" is the total amount of dirt that passed through the filter during the test.

(Note: The Purolator was reported to have a seal malfunction during the test and passed more dirt than it would have with a good seal.)

Initial Restriction:

Initial Restriction is the Filter under test’s resistance to flow at 350 CFM.



Dirt Passed Versus Total Test Time

This graph shows each the duration of each filter’s test versus dirt passed (Accumulative Gain).

(Note: The Purolator was reported to have a seal malfunction during the test and passed more dirt than it would have with a good seal.)

In the chart above it’s important to note the different test durations for each filter. The AC Delco filter test ran for 60 minutes before exceeding the restriction limit while the AMSOIL and K&N tests each ran for 20 and 24 minutes respectively before reaching max restriction.

In 60 minutes the AC Filter accumulated 574gms of dirt and passed only 0.4gms. After only 24 minutes the K&N had accumulated 221gms of dirt but passed 7.0gms.

Compared to the AC, the K&N “plugged up” nearly 3 times faster, passed 18 times more dirt and captured 37% less dirt. See the data tables for a complete summary of these comparisons.

Dust Loading:

The dust loading curves show graphically how each filter responded to a constant 9.8 gms/min dust flow before reaching the maximum restriction limit.



It’s interesting to note the shape of these Dust Loading Curves. The AC and Baldwin filters each had near linear responses until reaching maximum restriction. Restriction for these filters increased at a constant rate versus the 9.8 gms/min dust feed rate.

The other filters, most notably the oiled reusable types, had an exponential loading response before reaching maximum restriction. These filters had a lower initial restriction, but they became exponentially more restrictive under a constant flow of dirt.

This runs counter to the "myth" that oiled media filters actually "work better" as they get dirtier.

Also notice the length of the curves as it shows the relative test time for each filter (time to max restriction).

Restriction to Flow:

The Restriction to Flow curves graphically show how each “clean” filter responded to a steadily increasing flow of air up to 350 CFM.



The Flow Restriction response curves for each filter have the same basic shape. However, note how the AC Filter, which passed the smallest amount of dirt and had the highest dirt capacity and efficiency, also had the highest relative restriction to flow. The less efficient filters correspondingly had less restriction to flow.

This illustrates the apparent trade-offs between optimizing a filter for dirt capturing ability and maximum airflow.

Cost is Rs. 1300 + 200 for fitting ...

Last week I rode in night with highbeam almost 1.5 hrs continuous . I didn't find any problem with the battery power ...

Why din't you go with projectors ?? Using HID without projectors are really messy for on coming traffic.

Yes light is great.
If you put projector then it will be more better.

Please check the beams angle so that it doesn't hurt on coming traffic(I feel like your beams need an adjustment). Adjust it if required.

I face HID blinding me daily on Highway by some insane riders/drivers who have their beams set to fetch UFO in space. Even some cars have same.

But Even I have felt HID literally blinds the on coming traffic. It's really a request to go with projectors.

Ride save bro!!

Initially my plan was to fit a bi xenon projector. But the headlamp cover glass has to be removed to fit the projector inside the lamp assembly, and this job can be done only by an expert. Presently I m working in a rural village of MP related to my project commissioning. I couldn't find a good mechanic in this area to do that job. So I bought an HID and LEd pilot lamps.

This is the only CBR in this place, may be in this district ....

These pics were taken in the night just after installation ... After that I have adjusted the beam ... As you said, HID blinds those coming from opp. side ... I am not a careless driver ( I think ), and always following traffic n safety rules ...


RIDE SAFE ... WE HAVE JUST STARTED OUR LIFE ...

@jomidolges: great post there! Good find!
We need more such eye-openers. But even so, there are people with 'have cash, will burn' thoughts who will try aftermarkets. After all, the bazooka sound IS appealing! Isn't it?

upgraded filter on cbr...

Hey guys... Just upgraded my cbr with a high performance air filter...
It sounds soo awesome..
Check it out.
MEANEST SOUNDING CBR IN INDIA.. POSSIBLY - YouTube

Those who are having huge bank balance can try many after markets ... but if some of those mods doent make any change in looks or performance, then is it required ??? I talked with many people those who are installed after market filter. They said that there is a slight increase in performance above 100 kmph.

Dude,

give more details about this mod .....

got this green high performance air filter.
For 2000 with fitting.
Sounds soooo good...
And gives better sound as well as acceleration than k&n.
Increase in initial torque.
And great mid range as well.
the top end of the cbr is good already.
This filter is cotton based.
It is not oiled and gives better engine life than k&n.
I also have an ngk iridium spark plug installed.
That also helped in increasing low end torque.
after these mods I reached a quick 155 kmph top speed.
The base of the sound is simply unbelievable.

Hear for urself.

Will also upload acceleration and top speed videos very soon.

gear box problem help me

Hi friends i am getting some sound while shifting 6th gear in 5-6rpm.tat sound like smashing some metal in gear box.but after some time it is come to normal.this problem happening twice a day.Wat happen to my fireblade

Re: Honda CBR 150 R

Is this a good bike bro?

Read this thread and find it for yourself.

Sounds so sexy ...

Pls provide the model number of this filter...

Is it possible to purchase online ???

And about the NGK plug,
CBR is having factory fitted NGK plugs ...then why did you change it ???
