Good to know that fuel burn rate. I have a 100 thatís going into the Venture 60. Havenít run it yet at all.
Any favorite prop?

We started relocating the vent from the rear plate to the front very early on The second FA-45 I bought home got that treatment right out of the box. Most Saitos here are side mounted or 45 degree on the downside

Probably a good spot. I have at times placed them there as well.
as well. Make sure the end of the fitting has adequate clearance to the cam. I started going to the gear area thinking that spot may allow better oiling of the cam and lifters. A bit of a toss up either way
The thread is 5mm x ,08.

I moved the vent to the cam housing on my old high compression 1.50 but it didn't accomplish anything so I bought a new cam housing and put it back on the back plate. My OS .56 Alpha came with no vent so I put one on the back plate and now OS has done away with the no vent/recirc system on the .56 Alpha.

They changed the 56 Alpha designation to this and discontinued the original 56a.

FEATURESBlow-by oil exits through the breather nipple on back plate for more
stable operation

Seriously guys i don't get this whole thing about where the breather is located,dave has posted many pics of a saito engine with the backplate removed and you can always see a big pool of oil in the engine.It gets splashed around,give it up and argue about how much gas you use getting to the flying field or whether the OS system of recycling oil waste is better and would it work on a saito? should you put that stuff back thru the engine if you are running all synthetic which turns to one flash and your ash on a lean run and can you run a lower oil ratio as a byproduct of recycling oil thru the engine with a bit of castor in it,what's your thoughts jesse

The 125 turning an APC 16 x 6 at 6,000, that smoke will make your hand very wet and very hot in a hurry. With the CHI at 30 degrees btdc it turrns the 16 x 6 at 9,150 almost peaked.
Pete, the OS 56 has a tiny pipe up through the cooling fins that carries oil to the rocker cover area.

Also, anybody who has fooled around with mechanical stuff knows that if oil can go somewhere, it will. No need to worry about the cam. And, oil will quite often go where you don't want it to.

PS, Pete I was 76 years old yesterday, how about that?

SWAK Teflon/Acrylic ester anaerobic thread sealant. Swagelok SWAK MS-PTS-50 Anaerobic Pipe Thread Sealant With PTFE, 1.69 oz tube



The cam and lifter area is especially oil hungry. The rod bearing is not the question.

More about getting more oil, not just some oil. Also helps when using after run oil. By injecting the oil at the front, you are displacing the old fuel, moisture and other crud away from the cam and bearing and replacing it with fresh, clean ARO. We started doing the relocation early on and use the relocation often. Intended to improve oil migration to that area. And it does. There is a noticeable difference over the long haul. Same fuel, same after run oil etc and the bearings do last longer and there is less tappet and cam wear. Do not do this with sealed (rubber sealed) rear bearings but metal shielded bearings are OK.

The sealant on the nipple is SWAK. An anerobic, Teflon based thread sealant. By far the best stuff I have ever found for the exhaust threads too! Permatex/Loctite makes a similar product that they give a slightly higher temperature rating. Doesn't work as well as SWAK on these engines.

Here you go Jim, a 100 with a TurboHeader mounted without adapter and my probably over built degree wheel, it has a 4 oz lead weight on the back and carefully balanced wit the small screws on the right. I balanced it on a crankshaft with no rod or piston on it.

Dave,

Were you told to go smoke some pot in the back yard?

Don't think this is what they had in mind..

Is that Wildcat or gasoline fuel?

I never smoke pot when engine testing but occasionally I do end up smoking grass.

I just happened to notice the flower pots at the rear of the bench were getting smoked

The engine looks great!

Yes sir the 1.25 always had the vent in the back plate, the 2.20 had the vent in the back plate also but had a boss cast into the cam housing where a vent could have been place.
