RE: Clocked the SA F-20!!!
Nice report.
If think some of you have seen in the past that Ive recommended the TT46 pro and jett-stream as a 'budget minded' speed engine. You can see why.
That 15,000 on the ground is about right. You want the engine rich at launch - it needs the extra fuel once in the air and it unloads. Leaned out that should peak near 15.6K or so, so at 15,000 that is backed down 500-600 rpm - ideal. It will easily unload over 16K in the air. That is a good target for the TT46 setup like this.
