I'm leaning towards the uni filter as it's shape will be perfect for my hood. I always ran with out a filter because i felt a difference in my 93 dakota when racing with filter on or off. Also the truck pulled more rpm than it would with the filter on. But I'm pretty sure the stock hood played a major role in that the filter was most likely against the hood reducing air flow.

Yeah I ran a 3" K&N... I was curious why you got different
number.. I also forgot what flow I did this at but I

I have to use a spacer for the air cleaner to clear the linkage and yesterday I seen that the front of the 14" dia filter hits the hood and holds it up a little... I'm gonna try angle cutting the spacer to see if that will clear... I dont want to go any shorter than the 3" filter that I am using... this is on my throttle body.. but it was about the same on the 850 carb.. but that was a bit lower(no spacer) EDIT Plus I'm dumping the K&N that was a gift to me.. but I need the flow

I had been running a cheap 14x3 auto parts store filter for the past few years..... Just installed a new WIX Racing filter. My setup is a RamAirBox breathing through the grille. Wish I could fit a taller filter, but 3" with a drop base has me right against the hood.

Litrally just recieved it from Summit yesterday and istalled in last night. Doubt I'll FEEL any difference, but I'll be watching the timeslip! No, I don't have a wideband. It's on my priority list, though; Might even get one this winter (???).

I really like those Ram type boxes with the hoses..
I'm trying to set something up like that with my cowl
hood

My RW dyno results with a single carb on the Modman Carb was a 800cfm AVS THUNDER KN 14x3 with Xtreme lid - 318 RWHP MOROSO 16x3 - same day - 333 RWHP No air cleaner - 277 RWHP    KN Hemi dual quad 2" high - twin AFB 500s - 358 RWHP Two lessons Ive learned over time... 1 - Carters hate being run without an air bell or cleaner. 2 - Xtreme lids rob HP compared to a decent size normal filter element. Joe Sherman has made similar findings on Speed Torque.

I need to find a set up for my tunnel ram that will fit under a 7 inch tall hood scoop.
If you go to K&Ns web site they have many different shapes of filters. You may have to get creative to build the base, but lids are easy to make out of aluminum plate should you need every last bit of room. For my race motor with a Dominater flange I used a drop base attached to an air pan combined with a 14x6 and a flat lid to get it under my scoop.
thanks for the info. I was thinking about trying to use a air filter that is used with the six pack set up? think it would flow more air than 2 9 inch air filters? I have 2 K&N 9 inch air filters but they are 8 inches tall by them self. if i had a shop etc i8 would just run the carbs through the hood with the 8 inch tall filters.
No way no how..
A 2" high oval 6 pack filter had 121sq" of filter area. (60.75 citcumference x 2" height.)
Two 9x8s = 226.16sq" x 2 = 452sq" !!!!
