hi i gotta XT , i just replaced the paper air filter with a K&N flat panel air filter , and im wondering if anyone knows of the actual benefit....as in how many kws extra....on the KandN website they claim a 8kw increase at the wheel, and the motoquipe dude told me that flat panel will do me as good as a pod....
wats the truth behind all of this.....whats with the BMC pods, how much were they, did u's need a custom box????
Dont know man. But have run 150 rwkws with a panel kn filter.So I know its good for that much power.Maybe a pod will make a difference? They say it will but I cant be bothered for now to change it.
i got 118rwkw stock on dynamics dyno, then put k@n filter and jmm plugs in and then got 116rwkw the mechanic didn't know much about the plugs but before second dyno run told me that the filter would give me atleast 4rwkw go figure!

basically your looking at less than a 2% change in the runs. To me thats close enought to be no different. I would say neither the plugs nor the filter had any effect whatsoever.
No surprise really.

yes it had stock exhaust and I think your right in your asumption that its close enough to be no different, maybe the filter is more for higher kw output .Have since put on a 2 1/2 exhaust no headers yet

I'd say theres the problem then. If the engine cant get rid of the gases any faster then all the intake and spark in the world wont help. Thats the problem with the stock headers, they really choke up the engines. They give the XR's the better heads etc than strangle them with a stock exhaust.
Would be interesting to perform the same test after headers and the exhaust you now have, might show a few kw extra. Then again, might not.
I doubt the K&N filter would make a massive difference, mayby 1 or 2 kw to be honest.

I am ready for headers now just gotta make up my mind which ones to get. Either jmm or pacemaker, when there on i will get another dyno and hopefully will get 130rwkw. would go straight for the jmm but i live in Queensland and the extra cost plus postage and then extra to have fitted once here is an issue

Ok Casper i think you just pushed me over the edge ,if i dont get the jmm headers now i will always be left wondering,i read the improvement in your car with your mods so they must be pretty good

They are excellent to be honest. People can bag JMM but usually its for the price, not the quality. Of course if you look at Herrods, SVO or any other major performace house, the prices are similar.
Truth is that you are paying more but you are also buying experiance and, IMHO, quality.
But, to be sure, I strongly suggest ringing JMM and, if you have time, PM a few guys that use them on their cars. I think you'll find that 99.9% of people that use them are very happy with the product and service and its mostly those that dont use them (or think they are the motoring equivilant of tarzan) that try to pay out on them.
Anyhow, considering that there are very, very few I6 NA cars running in the 14's with stock internals (and stock cams), even less that are auto, and none that are a heavy ass VCT AU, I'd say my cars 15.02 is pretty good testement to the JMM gear.

ooops,where did i get Mildura from sure i read it somewhere, anyway typical melbourne i get lost every time i visit. Wheres altona? is it a suburb or in the sticks
Very true. Went there myself a couple of weeks ago...am extremely impressed. Highly recommend them to anyone.
The main reason I drove to Melbourne and had the work done at JMM is that age old idea of 'workmanship' and 'pride in ones work'. Jim and Brendan have a vested interest to see to it that the work is worthy of their name. Brendan (Jims son) has a real passion for the job. If you go anywhere else, the mechanics are just being paid to install a part, made somewhere else by someone they don't know, or care to know.
Call me old fashioned but that makes a huge difference to me.
and engine can only breath as much as it can, the factory units are designed to flow pleanty enough for the car breath at full rpm (and little extra), the replacement unit potentially flows more than the factory unit, however the engine is still not capable of breathing more than stock, hence the new filter will not being able to be used to its potential. So without intake (and especially exhaust) mods there will be no "real" benefit in a higher flowing unit, otehr that you can keep reusing it. I hope that makes sense to you guys.
