I have been running a Mr. Gasket / Hilborn style scoop on my carbs since I put the engine together. No air filters, just the coarse mesh screen/foam that they come with.
Two different engine builders have informed me that the screen/foam is an air restriction for the flow that I need to feed air to the monster. I have two 850dp holleys, 8-71 Hampton blower, 540 ci Arias/Chevy engine. Has anyone else found the scoop/screen to be an air restriction?
This year I went from 23% blower OD to 38%
blower OD and am only getting 14.5 lbs.boost
at 6000rpm. I thought I would get a lot more boost with that much OD. I never concidered that the scoop screen could be an air restriction.
