So your dropping the 8 into 2 and now going with 8 straight pipes that bypass the adapter plate and go into the inner can .. where they see each other for the first time ... Is that what your saying ... ???
Chaz= thinkin, power has never seen/driven on an 8 lane highway ...
So the correct answer would be .... >

CR for a Merc V6 , 5.5-6.5:1 ? Tough to get the hp without a bunch of dynamic produced by stuffing.

116+ H.P. from 30 C.I. same trapped /CR maybe less.
If you need me ... err ... Power to do the math for you 2.5L /153ci ~ 3.0L/181ci or worse yet a West Bend to see how anemic the "invention" is ..
Ohh what the heck, one more I told ya so before I turn in for the night ...
153/30= 5.1 x 116 = 591.6
Chaz = recalling something about 600 HP decals ...

Port to port makes the wide power, the can only added at certain narrow rpm range.
Like that bicycle engine
CR on the Merc, still needs high octane to satisfy the running psi. 6.5:1 2.5 carbs, damm that should make at least 89 hp.

Back to page one... Really , thats all you got ... Pppfffttttt
I said OMC did it the best, but still fell way short.
Your retention level is that of a third grader .. ( no offense to third graders )
If you cant see the entry angle run straight into each other and then the exit angle of the OMC takes a sharp 90* @ the junction.
While the Rotax pipes "merge" and continue in a straight line .. then well, there is really no hope for you ...
But then that's why you only have paper mache engines to show. Full of theory, empty on reality ..
Chaz = thinkin, Kind of hard to get a plug reading on a paper motor .. aint it

You're blocking it out, let the principles soak into your brain. Like many have said, you're a good welder, make a better exhaust system if you can.
The wave pressure front will go to all passages and ends independent of the ex gas flow direction well behind it headed to the tuner end.
Look closely at the video, after the cylinder has been plugged in beneficial range before closing by its paired cylinder. When the piston is approaching TDC, the closed ex port and passage is hit again by the pulse pairing of the two other cylinders. Getting any idears.Last edited by FMP; 09-04-2019 at 11:34 AM.

Theory and principle .. then there's reality.
A young boy asked his father what the difference between theory and reality was.
The dad said .. follow me son.
The dad asked his wife, would you sleep with Brad Pitt for a million dollars ?
The wife said, it is a lot of money and we sure could use it ... so yes.
The dad went to his daughter and asked , would you sleep with Brad Pitt for a million dollars ?
She responded, in a heartbeat !
The dad then asked his eldest son if he would sleep with Brad Pitt for a million dollars ?
The oldest boy said .. Ohh yes father I would.
The dad then looked at his young son and said .. you see son .. In theory we are milti-millionaires . But in reality, we live with two hookers and a homo ...
The moral of the story ...
Theory :
You read all this old crap that the "big two" used at the patent office to try and make it more difficult for the other to build outboards and see it as being marvelous invention's ...
Reality :
I'll continue to read sparkplugs, piston wash, exhaust ports, carbon trails in the head, heat patterns on the quench ring.
All these are for all practical purposes, single-cylinder engines stacked in many different configurations. With only one common denominator, the exhaust log.
I see first hand the horror's of multi-cylinder two strokes exhaust haphazardly joined together. And the horrendous resulting damage from corrupting the neighboring cylinders charge.
If your lucky, you only have to dig bits of ring out of the head, the ones that are not so lucky, need the block welded back together, bored, oversize sleeve installed, then bored back to size, decked ..etc
Sometimes you have to roll it to the .44 cents a pound pile and start over.
Like I said, I've repaired more blocks this year, than outboard motors you have owned your whole life. I can't ignore the trend I see .. obviously, my day to day experience in reality means nothing to you. Do me a favor, If you ever do wind up owning a big V-6 and find yourself burning up the bottom two holes .. Please don't ask me to fix it or what I have done to lessen the issue ..
You'll have to forgive me if I don't buy into the fairy tail. But if you want to live on fantasy island .. keep lookin for de plane ..
