I dont like drop base air clearers.. they change the direction of the air(restriction) but if you have to use them then you have no choice... just remember ALL air cleaners are a restriction.. I did a few years testing air cleaners for Chrysler  I did back to back testing at the track this summer. A K&N filtered drop base aircleaner vs. no aircleaner at all. Identical 11.41 times and mph with and without. All you people say I didnt see any change.. did you start changing jets to optimize without... no... you took it off and didnt see a change.. because you were jetted with it on If you have the room.. put a ideal entry on it and see what happens.. you WILL be adding fuel

I have not tried it with the bigger motor yet though.

I will say it again ALL filters are a restriction and its a proven fact... just because you didnt see any change DOESNT change the FACT that a filter isnt a restriction... The real question is, is the restriction offset by the straightening/smoothing ot the airflow into the carb? How much HP difference, on average, did your testing show? Was it dynamic, real world testing or in a dyno cell?

Was it dynamic, real world testing or in a dyno cell? This was on a filter flow bench... also just like guys say that the filter top is better... I've done that type of filter on the bench and at the track.. that top hurt power... I have one right now but I put a plastic cover over it.. reason why.. the 2 directions of air flow hurt the total flow.... BUT you guys do what you want

Very well could be but that doesnt change the FACT that ALL FILTERS ARE A RESTRICTION.. if you have the space put on a ideal entry and try it

I had to have a drop base air cleaner to clear my hood scoop after building my 434 last year. When I dynoed it the guys at the shop were asking me about my set up and I mentioned that I thought I was going to need a drop base air cleaner. They recommend the one in the link I posted and said it made more power than any other air cleaner that they had dynoed. Ok... I quit... filters are GREAT.. they arent any restriction

K&N apparently did some dragster/pro stock scoop filters but never really heard the results........

I just haven't seen enough restriction to warrant removing the filter. Especially when I race at a lot of tracks where we park on dirt/grass. No need to get pissy. Just sharing my personal testing and results...

If the shop Justin was using does a lot of dirt car motors, they test those type things. At least that's what I took from the post

Mike pleas re read what I posted. They didn't say it made more power than NO air cleaner. It made more power than ANY AIR CLEANER they had tested. And this was his other post Monte... as I said EARLY in this.. if you have to you have to.. still doesnt say its NOT a restriction.. which I STAND BY

And this was his other post Monte... as I said EARLY in this.. if you have to you have to.. still doesnt say its NOT a restriction.. which I STAND BY A couple of us have quantified our results with real world data to back it up... Just because you use words like "FACT" and "RESTRICTION" doesn't make it so in every case.
