Such a device could be loaned/rented to members (or even NON-members for a premium... still cheaper than Dyno time in a race shop) --------------------------------------------- I believe and easier , less expensive way it to check your installation is using Tracy or Ed A's well known performance prop and simple do early testing with it. You will know if you are in the ballpark with total installation, ie intake, exhaust, etc. I did this with Ed's prop and flew off my 40 hours with it. Now have got to get my prop reduced in power consumption and either buy Ed's or fly with mine. Hope to do so soon Ed, thanks for your patience.
