Wonder if a simple band-pass filter triggering a red LED on the dash would work. You'd have to fool with it to get the right frequency passed. Might work, might not. You might be able to use sound software and fool with the frequency analysis via a laptop. Or make a quality recording... naw... might lose to much high frequency.

Aren't you afraid they'll let a contract on you? Sheesh! That would be my knee-jerk reaction! 
| Quote: | X Planes would probably be your best choice.
|
I haven't used x-plane. Some folks who do have told me that MS FS is easier. You could search around and see if anyone has created a Kolb for that sim. But it might not be any good. some sites have user ratings of each plane.

There are some folks that have them. I know one EAA chapter has one built into their engine stand. I have a pic of it with a corvair on there. Think they use a hydraulic cylinder (from a jack?) to resist the pressure generated by the prop. The pressure within the cylinder is displayed on a pressure gage. Or it might measure torque, not sure.
With a lil work you could add another such cylinder to resist the twisting moment of the engine on the stand, thus acquiring a torque number. Note the rpm and you can have a hp number too. With some transducers and a single-board computer you could automate the data acquisition during a run, at different rpm. If you designed a universal ignition system tied in to the CPU, you could also vary the timing throughout a run and generate an ignition curve/torque. of course you could leave the computer out and do everything manually and generate the same set of numbers. If you build it can I borrow it?

I am thinking about using one of my Geo throttle bodies for my generac. Not sure what ECU I would use, there are several possibilities.
| Quote: | you want a ground plane that radiates out from the antenna
|
While this is probably a great idea and makes an efficient antenna, there also exist designs that require no ground plane.
| Quote: | he went to the 1.3 liter engine..
|
I ahve worked with the 1.3 liter in my Samurai rather extensively over the past 13 years. It puts out heaps more power and low-end torque than stock. It has enough to be fun to play with off-road. I sometimes beat much bigger machines up the dunes.
| Quote: | making sure you don't have a ground loop in the antenna feed line (grounding the coax at both ends).
|
Hmmmm... Isn't the coax grounded inside the transmitter? If so then does this mean we shouldn't ground the ground plane to the frame? I know nuthin of this sorta thang.
