I am new here so please forgiv if this is a redundent question.
I bought a 22' Placecraft deck/Cat with a 540CI whipple charged set up.
I an not sure if the enging combo is what it could be.
I think my carb may be too small. It dynoed 668 HP at 5600RPM @ 6# boost.
I looked up a carb chart formula and this is what I found
CI / 1728 X RMP / 2 = "Carb Size for N/A at 100% VE"
Turbo/ SC applications need a multiplier added as well:
14.7 + boost PSI / 14.7 = "Multiplier ratio"
I run a 540CI @ 5# boost at 5400 RPM
540 / 1728 X 5400 / 2 X 1.34 = "1122 CFM carb needed"
Is this a good formula for carb sizing?
If so then I think my carb size is too small. I have a Demon (like holy 4150). I think these carbs only go up to like 850 CFM?
I was thinking about changing blower pullies for more boost; but I am thinking that just going to a bigger carb would probably increase boost on top end by itself.
Any help would be appreciated
