| Subject: | Re: Trial Fit of 4 into 1 Exhaust |
I have a similar exhaust on my 360, except it is not quite as long out the
back of the cowl.- I only have one hangar just aft of the firewall and no
ball joints.- The only problem I have had is I used a 3/4"x0.015 inch st
rip of-stainless steel to hang the exhaust.- It cracked after 125 hours
or so.- I just have two strips of the same dimensions now.--=0A-

| Subject: | "P" Mags for O360 A4M |
Has anybody here converted their engine from the old Magnetos to the "P"
Mag with the built in generator? If so what do you think about the benefits
versus the cost?
My magnetos have just hit the 500hr point and I am debating whether to
overhaul them or just bite the bullet and go with two new "P" mags.

I have two mounting points on either side of the tailpipe following the 4-1
collector.- My initial thought was to put a clamp over that position and
use a flexible hangar on both sides.- This would give some movement to t
he system and dampen any vibration.- Not sure though if that will be enou
gh support for the entire system.- The mechanic that I am working with is
coming out this weekend to help me locate and drill for the exhaust temp p
robes so I will discuss the options with him.- I was going to try and dri
ll them myself but he convinced me that it would be much easier to use his
jig and drill it rather than to destroy some of-my bits-trying to penet
rate that stainless steel.=0A-=0ABob=0A =0A=0A___________________________

| Subject: | Re: "P" Mags for O360 A4M |
I have had dual pmags on my parallel valve IO-360 since new.- It has 185
hours on it and 3 years now.- I had to send the pmags back once for an "A
D" and I had-to send one of them back due to problems with that mag keepi
ng the timing.- All I paid was shipping both times.- I have never had a
problem in flight though.- You should see a noticable improvement in fue
l efficiency and a big improvement in starting and hot starts.-=0A-=0AI
think the pmags are the best option out there.- I originally had aircraf
t spark plugs, but switched to auto plugs.- They say the auto plugs give
a bit more power and they are cheap.- I just put new ones in every annual
.- =0A-=0AI initally set the timing right at TDC, but the engine would
sometimes kick back on starting.- I recommend setting it to 5 degrees pas
t TDC to elimate any chance of kickback.- Then use the high advance curve
(which is the same as the low advance curve-with the timing set at-0 i
nstead of 5 degrees past TDC).- This-was okayed with the pmag guys.-
I also have 10:1 compression which probably makes kick back worse.=0A-=0A
>From a cost standpoint it probably makes sense just to overhaul your mags.
- You can get an overhaul kit and do it yourself pretty cheap.- If you
were looking at buying new mags vs the pmags I would be 100% for the pmags.
- If you are going to send your out for overhaul then I think it would st
ill be a good buy to get the pmags and ebay your old mags.- The pmags sho
uld increase your mpg noticably and you-might save money on spark plugs i
n the long run depending on how often you change the aircraft style plugs.
