I fit 12" in her!
i have never dyno'd or raced my car with the air filter off.. but i have seen some subsantial gains at this hp level.
what kinda ponies you think there is to gain between these two and vs. none at all?
the 7 was very dirty too

Are you going to dyno w/ the 12' filter and w/o filter MM just to see?
off topic, YES that f'in hood is wicked stryker14!!!
yes, i'm racing next sat at mir and i'm sure dynoing (afterwards lol) to get the tune straight.
my results unfortunately may not be very telling, as i am doing all pro heads at the same time as the filter.
i can certainly dyno with the new one and without one.
thats what i was thinking, could be over 50hp just filter... i may skip 1krwhp completely.. . ya right.
maybe turbo.. http://www.filterpower.co.uk/univers...ered_clamp.htm
Now strangely for a 6" neck filter say RU-3050 ( I am using ) which dimensionally is about 4" shorter, although base is approx 8" tapering to 5" and 8" long it is rated at 585 bhp n/a. Seems a massive difference for a filter that isnt really any bigger ?
RU-3280 is 10" long, same 8" to 5" yet n/a rated to 625bhp.
It looks like you might have room to go for something shorter and thicker.....no pun intended lol
I have a 4" to 6" bellmouth to attach my RU-3050 to my blower.






Thanks for the comments on the hood...you guys should go to the appearance section and check out the intake i painted for a member on here.
