 |
|
As a newbee to this whole aviation arena, I now have an almost completed RV10, with an engine that actually runs.... and quite well..... that being said I have some questions and clerifications that I need.
1. At start in colder temps (40 deg F) with mineral oil for breakin, what would be considered too high of oil pressure? I was seeing 91, and then it dropped to 88 as the oil temp rose to 107. Both readings at approx. 1300rpm.
2. Without the boost pump, I was getting fuel pressure of 34psi.. normal?
3. I have dual lightspeed ignition and have the AFS4500 and a Van's tach. So far neither has produced any rpm movement. Ideas?????
I wired one lightspeed to the AFS, and the other to the Van's tach.
Really appreciate the help guys.

Have you looked at your POH? It should right next to the registration in the left side pocket

Can't help you there...sounds like a wiring issue.

Rick, I have found that the BEST info available usually comes from our RV crowd..... with, of course, the exception of a few,,,, no finger pointing intended. One friend, an RV6 pilot, was really concerned about both pressures. But according to Lycoming, they are normal. So I just wanted to get a few more opinions.

I know!! Sorry, I just couldn't resist poking some sarcastic fun...Especially since all I've been doing is sanding and filling lately. Regarding your RPM problem, on the Vans tach did you install the mag sensor on the correct port on the left mag? IIRC there is only one port for the sensor that will work but there are two ports. I would bet the wiring is not correct on the lightspeed but it may be an issue with the setup on the AFS, Call Rob Hickman at AFS, he will have that answer for you for sure.

As long as it’s within engine design tolerances I wouldn’t lose any sleep over it.

No apologies necessary.... especially from you. What would this site be without your wit and humor!

Lycoming permits the 4 cylinder version, IO-360 in new Cessna 172s to
run over 100 psi oil pressure. As far as I know, there is nothing
special done to contain that extra pressure.

I have dual Lightspeed ignition on my 8A. I had a no RPM indication when I
first connected one to my Grand Rapids EIS. A call to Grand Rapids produced
a solution to change one resistor on the EIS board. Problem solved. You
may need to do the same with your AFS4500.
I also have a Vans tach but it comes off an engine sensor mounted in the
standard tach port on the accessory case, not the ignition.
