• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

I estimate approx. 96 square inches of inlet opening on my S1S cowl. I est. approx. 196 square inches of outflow opening at the bottomthe cowl (1 to 2 relationship). I've heard that the rule of thumb to provide the best flow is 1 to 3. I can enlarge the opening at the bottom of the cowl a bit, or bend alip to help increase the low pressure vacuum.

Any advice?
