just had the calculator out for the last few hrs,
The numbers add up well for an RV10! thinking kids etc in the next 2 to 5 years as well. (as i have been informed by the other half)
with the $75,000 SMA Diesel (actual USD) burning 7-10Gph. for 230Hp to 10,000ft.
the SMA is $25K more than a nice IO540, but over 2000hrs, fuel burn saving are approx $60K! engine TBO is 2400hrs..
How well do RV10's perform with 230Hp? (up to 10Kft)
according to the Vans website, speeds are in the order of 5mph slower. but you do gain a few miles in range.
