To the best of my knowledge you cannot develop over atmospheric pressure (14.7 psi) without a blower or compressor..

Yeah, but I'm not sure how cunnilingus relates to this whole engine venting issue.....
Same rules apply, I learned along time ago to use scuba gear when going diving ! Hah ! |
Pretty much as air is drawn or forced into the intake, the vents into the bilge will allow the air to be drawn into the engine compartment. You just need to make sure that the vents into the bilge are large enough to feed the engines. The more HP, the more air that is needed. How do you know the right size?....that is above my pay grade 😳

Randy I agree very hard to go positive |

I had always heard (grain of salt time) that if you run the engine up to max rpm, then crack the hatch an inch or two. If you get a few more rpms, you likely need better venting. Don't know how true that is but it sounded reasonable at the time.

having enough air to run is nice. having enough airflow through the bilge to keep gas fumes from accumulating to an explosive mix is much nicer. they put those cute little fins on vents one side facing forward, one side aft. I don't know if that works or not. if they are where airflow causes low pressure not much will get in. bigger sportfish sometimes have engine air intakes going straight to the side vents so they get air that hasn't been pre-heated by the engines and exhausts. even the hottest day the ambient air is cooler than your engine compartment.

For visuals to make it easier
502cid x 5000rpm = 1,255,000 cubic inches (726 cubic feet) of air per minute 2 x 502cid's x 5,000rpm = 2,510,000 cubic inches (1452 cubic feet) of air per minute The following is the size of 1000cuft http://indulgd.com/wp-content/upload...cube-home2.jpg |
Post 11 is killing me. he must have watched Dr. Ruth way back in the day for all that proper terminology lingo
