The levee landing (gosh if I remember right) was a extreme amount water entering the engines at idle throttle. The engine mfg then changed the design as it was only tested with that amount of water in-gestation at higher power settings. They ran test and duplicated the scenario on a test stand. Can't remember what they changed but the engines now will take more water. I think I saw it on air crash investigations. Watched all of them. Aaron Sent from my iPhone using Tapatalk

No prob at 4qts. Just remember on a long climb if hot the oil acts as a heat sink. The less oil the quicker it gets warm but on the flip side the quicker it cools. Good advise above on oil and/or filter analysis. If it's aluminum that's better than steel. Also nothing to do with the 50 hour filter changes as the filter shouldn't be a issue even beyond that. These motors just arnt very precise. The technology is 60 years old, and it's part of the game. Go have fun. Sent from my iPhone using Tapatalk

Cocktail hour was coming and ATC didn't want to complete the paperwork required from a plane declaring the big "E"..... So he slid in the oldie.... Sent from my iPhone using Tapatalk

Hot temps do take off about 5kts.... Sent from my iPhone using Tapatalk

Speaking of crappy spark plugs I pulled the 1 year old 150hour set out of my boat and replaced with the factory recommended AC Delco plugs. The champion were the equivalent marine ones and but 1 out of 12 plugs (twin v6s) had corrosion and slight rust around the base while the others had none. I think the plug was shorting out and the energy actually created the corrosion almost like electrolysis in the water where it eats the drives. Previously I had a intermittent miss in that motor that I was chasing and it's gone now. I've never seen a AC Delco or NGK plug do that but sure enough the champion quality hits again.

So what happens is similar to a tuned exhaust in a race car or motor cycle. The header length and position of the exhausting header is located next to the header of a cylinder that is next to be exhausted so basically the one headers rushing gases create negative pressure next to the header about ready to be exhausted which in turn creates less back pressure and gets more hot exhausts out lowering Chts and making more available room for intake air (O2) for the next charge. The stock system has all the headers dumping into a muffler so the more exhaust released the higher the pressure the next header/cylinder has to over comb in order to evacuate the hot gasses. It's just like the poop tank on a over shore boat. Open the valve (no pump needed) and the water rushing past the discharge hole sucked the poop out. In the case of PFS the previous header creates the negative pressure. It's pretty simple and surprised the stock configuration doesn't utilize this basis of design.

Ok the reason most PF customers as well as I saw a drop in CHTs is because there is more heat extracted with each exhaust stroke as the PF creates a vacuum or at least less back pressure aft of the exhaust valve which in turn evacuates more hot exhaust gasses. With the PF the plane is very very marginally faster, 1-2kts at a given fuel flow, but it will run 5-6kts faster than the stock exhaust if more fuel flow is applied. I installed the PF because my muffler was cracked and instead of spend money say $1,100 repairing the old system I got all new for $3,800, with a modest performance improvement. The heat is just as effective as stock but only if the additional header heat kit is installed. And no there is no spread sheet I don't care that much wether another pilot wants to install the system or not and if you don't want to spend the money I could care less. Just passing along my experience and I also could care less if PF sells 1 or 100 or no kits based on my review as they have yet to offer me a percentage of sales. If you like it great if you don't ok no skin off my back. Sent from my iPhone using Tapatalk

It's not just a performance mod, it a cooling mod too, taking 35f or so off head temps. Sent from my iPhone using Tapatalk

Byron, On mine I couldn't get it to stop no matter what, even with the air dam. If fuel flow was kept up and ran ROP it was fine but as we all know that's not the point of having GAMIs. Mine is only about .3gph spread so I just stuck the lycs back in. Sent from my iPhone using Tapatalk

I KNOW WHAT IT IS! you are running GAMI injectors right? They leak out the vent hole while leaning slowly and sometime continue to leak when fuel flow slows it just happens to coincide with right about peak and leaner. The base of the injector is concave where lycoming a is flat across. I think the mooney induction system (and some beech products) is efficient enough where the pressure differential between intake and atmospheric is close and the concave gami catches a bit of the intake pressure spike when the intake valve snaps shut causing a bit of fuel to spit out the vent hole. Back off .4MP and the problem goes away. Or get a refund on the GAMI injectors as even John Paul at GAMI couldn't make my plane run right with them. Sent from my iPhone using Tapatalk

Nothing is free. If power was reduced back to the previous throttle position that yielded 143kts, fuel burn would be exactly the same. The PFS allows the plane to go faster if desired with more fuel. I installed it on my J and have 1000hours without it and now 350 with it. There are other benefits though. Chts are reduced due to more hot exhaust being pulled from the cylinders than what the stock system does. On the power flow there is a vaccum created that help evacuate spent gases so they don't add as much heat to the cylinder. I too repaired my exhaust several times before purchasing the PFS. The annual maintenance inspection and lube is easy, and if done pretty much eliminates consumable parts. Sent from my iPhone using Tapatalk

I have wondered if the bladders might slow down fuel escape enough to prevent or slow down onset of fire. Would be interesting to know if there has been a study on this... It is tragic how often it is he fire that gets people, not the crash landing. Glad to see nothing ignited, there was plenty of opportunity. All the bladders would do is add rubber to the fire.....

Here is a good example of how fast ice can accumulate when descending down though a 2000 ft layer of moisture saturated air at -5c. This only took about 2 min to accumulate. I will say there was no measurable loss in airspeed but if this was 2 min worth how would 10x be which would be 20 min? Would have had 3-4inches if ice....might not have been able to stay in the air. Be careful this winter. Sent from my iPhone using Tapatalk
