How about 12,500, 161 knots, 12.2 rich, have not gotten to testing LOP. Was testing yesterday for 5 minutes at 14,000, lop 157, 10.8. But would not vouch for that one since it was a very short test.........BTW, pulse Ox at 82.....that is what I was testing.......

Before believing any numbers..... and I had this problem recently, be sure that your static is correct and do a GPS GS box to verify.
Our initial readings were -9 knots..... I thought we had a slug!
Small mod to static.... I had the fastest -10 with a +6 knot error.
We are now about right. We get 160-164 knots at 40LPH and a bit less when fully loaded.

speeds
After we raised the ailerons slightly we had a increase of speed to now regulary 170-174 Knots Tas at 8500ft Verified. Rich of peak and 48lt an hour.
Friends have also raised there ailerons slightly and had the increase. Having said that these are the standard Vans numbers, so our plane is nothing special.

These numbers are right in line with what I am seeing. I am using 100LL, however.
raising ailerons
How much were the ailerons raised? some measure of degrees? some number of trailing edge thicknesses? other?

Speed vs 100LL/Premium
I used 100 LL only till I was totally comfortable with the RV 10. I use Premium only in the left tank and 100 LL in the right.
I live in Missouri and my understanding is that alcohol is illegal in Premium in this state. (Most people I know use premium only for home use such as chain saws etc for that reason.)
In any event I went to straight and level at 60% power or so and would switch tanks to see the effect at first. The only difference was a slight rise in EGT's (about 5-10F) with no change in speed or CHT's. The performance seems to be the same to me.
Daytime temps here are routinely around 90 F and I usually shoot for best economy at about 60 % power. I figure I get over 17 mpg at 170+ mph, on car gas. Beats my pickup truck and a lot more fun.
