Bob, AMA profiles typically are in the 75-85 MPH range, Sportsman profiles usually are much slower, typically 55-65 MPH.

If you can find them, K&B 5.8's on high nitro.  If we weren't limited to nitro content with muffler I think my Webra .32 will do 70 easy.  When is Tulsa going to have a carrier get together? 

My Webra 32 on a heavy Brodak Guardian (very thick airfoil section that does not help either) on 25% nitro would do 75+ mph. There is now a Webra 36 that should be a bit faster.

My stock Nelson combat 36 with an OS carb on 25% nitro fitted to a  Dehavilland Vampire(again a bit heavy for profile) does very close to 90 mph.

Well Joe you got me... The FJ was a great proof of concept design and now that I know the platform works I'm thinking about a smaller, lighter slider version for profile and also an even smaller version for 15 carrier. If these things work out I might just enter all 3 next year at Brodaks and not fly Old Time

You can fly ALL 3 and OTS.  Just tell the stunt judges you're busy and will fly when available.
