• 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 guys I have been told that installing 0-435 angle valve cylinder on my 0-290 D2 will increase my HP and get me close to a 0-320.
My question is, if this is true the angle valve 0-435 cylinders have the provisions for fuel injection. If I put the cylinders on my D2 and add fuel injection. What kind of HP increase would I be looking at?
What about if I added a stage 3 cam?
Also there is a guy in NC that is manufacturing 10.5/1 pistons for the 0-290 D2 now.
Not being a real engine man, it just seems I should be getting at least 160 HP if these things are done to the 0-290 D2.
What about electronic ignition.
What do the experts think?
