turning air cleaner lid upside down?
 

I've heard of people turning the air filter lids upside down so it supposedly lets more air into the engine. I could see how it could let more air in but wouldn't it technically be a dumb thing to do because wouldn't it let more dirt and debris into the engine?

Old, old trick from back in the days of carburetors. It really was not of much benefit unless you rejetted the carb to put more fuel in with the (slightly) increased air. There should not be an issue with dirt since the filter would still be sealed around the top and bottom. Been there, done that.

It sounded better! LOL

Oh, I figured it wasn't much of a big deal. But I was kinda curious about it and figured I would ask lol.

Did not know this... I read somewhere about someone doing it... but did not know why

Since the filter blocks the dirt thought and there is more room to let dirt in wouldn't you just have to replace air filters a lot faster?

Neve gave it any thought. The old style round flters were so cheap that it was not a concern.

It sounds badass when you flip the lids on round air cleaners. You can hear the engine sucking like you get with a CAI kit.

Wow that is some old school talking there.Half the kids on the forum are probably like,what is a round air filter and what is a carburator.Now lets not start talking points and condensers,someone is likely to have a heart attack. LOL:icon_wink:

Lol if that was the case that would be pretty sad, I'm only 17 and I know what all of that is lol.
But after discussing it I think I'm a try it out just to see what it sounds like.
