• 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.

OK, next question.
I am running a TBI on an 0-320. I know carb. heat for a TBI is not as important as it is for a carb'ed engine but it is still recommended by the manufacturer.
I am thinking that I could draw cowling heated air for TBI heat which saves needing an exhaust heat muff and related plumbing plus it gives me an emergency source for alternate air in case of filter blockage
Probably won't get the full 95 degree tempereature rise but . . . .
Hopefully, I can route the ram air and cowling air through the same set of "vanes" to give the TBI a straight intake shot.

So, what are the con's to this "brilliant" idea :)
Thank you,
