Short flame arrestor HP 500
Does anyone have any calculations on flame arrestor size and CFM?
My brother is dropping the HP 500 in his 22 Donzi today. His old one is off a 525 SCI and we're pretty confident it is too tall to fit under the hatch... I think it is a 3" unit.
I see Gaffrig makes a few 2" arrestors, but what is the right size to get? What kind of power loss, if any?

Is it strictly surface area or does the height / bend have something to do with it? I figured it was more than just surface area.

Causing the air to make a 90 degree bend is never a good thing. Thats why people run stacks when possible. But if your limited.....your limited. Not much you can do about that.

I went to a Gaffrig 10X2 for hatch clearance from a Merc 10X3. I ran the boat with it and without it on the same day with no change in performance. BTW Merc sells the stickers if you want it to look stock

If you still have choke towers on your Holley I'd sweat with a 2" unit.
FYI: Ran a 350hp SBC 20ft boat on a bunch of tests, back to back runs the K&N 9x4 arrestor lost just over 1mph vs no arrestor.
