SJ 50 vs Cast Q500 AAC
How close is the SJ 50 to the Q 500 engine.
I presently fly a racing cub in our Warbird racing. It has a Nelson Q500 SS. It has seen better days and I wondered if the SJ 50 can be made to run like the Q500 engines. I have a SJ 50 that I am not using because in stock form it just doesn't get me to the right speed to be useful for my purposes. Are there mods that will get the SJ 50 up to the rpm's that the Q 500 will turn?
Also, I look on the Jett website and all I see are one set of prices for the Q 500 and Q 40 engines of $325 and $375 for BSE. Are these the long strokes? Are these prices even accurate?
Thanks, Terry
