Factory claimed 14A speeds

I am writing a pilot operating handbook for the 14a I purchased. This has the original style IO-390, not the more powerful engine Vans now offers.
I know the 14 is a bit faster using the latest and greatest engine. What I need are the top speeds and cruise speeds at the different power settings for the original IO-390. Vans website lists the speeds for the newest version.
If anyone has a brochure on the 14A from back in the day, they would be listed on that.
Thanks much.
 
As far as I understand it, those details need to be done for each plane during the phase one as each plane can be slightly different based on weight, CG and other factors in the build. One may have more drag due to modifications or build quality or built extra light. If you are aiming to have accurate info for your PHB, then maybe it is best to gather the info if it was not done or documented during phase one.

Here ya go. This is cut and pasted out of the original RV-14/14A brochure. Note that as stated above, the RV-14 had/has a 200 hp engine in it.

I would encourage you to purchase the EAA Test Book and go through the tests. As Mehrdad Mehranpour ( Bavafa) mentioned, each is unique. Performing the tests will give you all the data needed to develop a really good POH specific to your airplane. Plus you may have fun!
 
This is good advice- I was planning to steal numbers for my RV8 POH, but every airplane is a little different. Specifically engine and prop combos. There's a good kit planes article on figuring out climb / descent speeds. A good excuse to go fly and get to know your airplane a little better. Then you can take the data and crunch numbers, make spreadsheets and graphs on the couch when you're bored.
