Pod Filters

[Alphamazing]

I've lost the will to debate this anymore, Srinath! :lol: While you're no doubt right that it spins up faster and makes more power up top, making the bottom end seem less powerful, butt dynos only tell so much; also you're probably true in the statement that with and engine like the GS's it won't make a difference because the engine is so low tech. I was just giving some of the science behind it and what I determined from it.

I got a lot of this information from my father who has dealt with, worked on, tuned, and modified cars and motorcycles since the 1960s. He's met a lot of people and knows a surprising amount.

The "they" referred to, is people that both he and I have met who have removed their airboxes or modified them. I've met a few of the FZ1 guys that did it when I went to North Carolina a few years back.

I would like to dyno a few bikes just to be able to see the changes.

PatrickInNC:
There's no need to be insulting and offensive. You ask me how I "came up" with all this science? I double checked what I was told with a book I have for engine workings (it's a text book for auto mechanic students) as well as various online sites. You can question me, but insulting me is somewhat counter prodctive to your efforts. Just because I am not running pod filters on my bike now doesn't mean I don't have experience with it. Even if I didn't, it wouldn't matter because I know how to look things up and read about things before doing them.

treybrad: Right now I'm running a K&N filter with a 137.5/62.5/20 jetting. I was planning to leave the OEM filter in there and get an exhaust, but since my Yoshimura didn't fit, I was SOL. I might be getting a slip-on soon, so if the jetting needs changing it will be. As for now thought that's all I'm running.

I have one word for ya ... KevinC - OK its a name ... but he used to be the expert on the air flow type dealio's ... I just know it semi instinctively ... just no other way to put it ... when all my class mates used to instinctively know structures (yea I studied Civil engg) I was the exact opposite ... I instinctively knew Flu mech ...
Cool.

Hey alpha fire,
No worries man, I wasn't insulting you. Sorry I came across that way. I was just wondering where you got this information from thats all. As you know because of how often you frequent this board, alot of people give "theories" based on their opinions, and no real factual evidence to back it up. I was just wanting to know where you obtained your information thats all. I usually just don't take peoples words for it unless they have the experience or resources to back things up. I wasn't insulting you guy, I appreciate the time and effort you put into posting the things you found about the subject for us to use. Ride on!

I understand ya Patrick.

And Srinath, I could so continue the airbox thing, but honestly I'm so sick of this now :lol: Maybe I will do a dyno run against treybrad's bike. Who knows. I'm poor right now.

You know I am just saying that - yes longer air intake is better for high or low speed (in fact there was one race team that did it with a honda hawk a few years ago) ... except that the GS air box and filter are tighter than duck Cheney's Aorta ... and as such liberating the bike from them does more good than harm.
Cool.
Srinath.

my useful input on this matter  (                                               ).

For what I read I'll install a pod filter after a couple meters of intake pipe, it might get the best of both worlds....   :mrgreen:

Definitely i think the GS500 needs more valves to make real improvements on power.
