Hi All, I got a call from Lycoming today about the options on my Thunderbolt engine. OTher than colors and ignition, the only option is whether to have the 2-1/2 lb accessory pump installed or not. traditionally used for a vacuum pump, Chris Gaymon suggested that the most common application today is to turn a backup alternator. The Van's RV-14s do NOT have this accessory.
Did you get the accessory pump drive? Are you glad you did or didn't? If you did, what do you use it for? Is there a question I am not considering?
Thanks for the help.
