If it's any help here is my Vans RV7 build site/diary.
www.go-7.co.uk
Go to the Diary pages to see the day by day progress or the construction section to see by topic - like Dynon D100, Engine monitor etc.
Regarding performance: My RV7 has a new Superior IO-360 with Hartzell c/s. The performance is fantastic. I am off the ground as I pass the numbers and 1'500ft by the end of Thruxtons runway. Was doing 200mph round the IOW the other weekend. Only have 18 hrs on it so far but have to say it was worth all the effort.
HEATH WARNING: Don't take a ride in an RV, as you will really really want one
