She`s got some get up and go .. still making sure fuel tables are good but a quick stab of the throttles she gets to 92mph pretty quick with drives level .. now Im running out of prop.
#5s had to be trimmed to the moon and it would take some time to get there .

Lower boost, less restriction in heads and intake. Lower IAT too, sounds good. Gas engines seems to be pretty worse about BSFC, your engine take 0,51lbs/hp/h, calculations for my Fountain diesel engine is under 0,3lbs/hp/h. So Transmash should make 1200hp only 336lbs/h fuel consumption, thats pretty interesting because fuel is now damn expensive.

I can appreciate that...but there is much more to BSFC than pocket book. But really...maybe they haven't done the math lately. $8 USG for 91 in BC atm.
BSFC from efficiency and range is a valid factor.
Ksalmine, transmash is an interesting engine for sure.You mentioned you opted to not go with turbines from their poor BSFC. I remember looking into some turbines a while back, and was surprised to see some really low 0.4 level BSFCs.
The blower fed BBCs are not always 0.5...they are often in the low 0.4s...and sometimes lower. Most of those numbers are WOT, so cruise may even have better numbers.
Some are in the 0.6 area.
Dan, really nice to see the results of dedicated effort through the many pitfalls and Mr. Murphy tagging along the way.
Nice to see the 6s get you up quick. You figure that is from the leverage of the props farther back? How are the ventilation tubes working out?
With more pitch, maybe the 100mph is on the horizon.
Well done.
