i am very well aware of Jon Wright, I witnessed it run a few times. Sat in it etc.
Attached is Lentzkows pipes

Glad your aware I was just telling you who he meant since you asked. We just happen to have both Jon's table top dynos, this one and the Contraptions which is totally self contained.

I was not aware Jon made real pipes for his merc. Anyone have pics.
Should add that Land and Sea also made pipes, though I feel like they worked much like most of the items the pawned off.

I took a pic of the OMC with the turbo and pipes when we picked up the dynos. Im trying to figure out what I did with it. He had lots of unfinished projects going on when he passed away. RIP Jon

I have a pic somewhere of the omc turbo project.
That aside, I’ve for the last
few years really wanted to find a land and sea turbo to play with. Fuel injection would be a giant leap forward

All true ...

"NEVER once have I mentioned expansion chambers .. you on the other hand , have mentioned them after every post I make"

PS you mentioned expansion in post 78, 83, twice in 135 stating how important the technology is , are you running for governor?
I mentioned it in post 113 and saying it doesnt apply to outboards and again in 136 saying yes good data but....

Of course , if you read the peripherals you would see that it was used in the context of helping you in identifying and labeling different sections of an outboards exhaust system .

Hey Chaz , Merry Christmas.

Merry Christmas Chaz

Quick question, do the bottom pistons get hammered the same on LH and RH powerheads?

Best wishes for the new year

Hillary lol.... I would donate money to get the clintons in jail

So Chaz, the collector on the 2 stroke is basically acting like a collector on a header for a 4 stroke? Getting the negative wave to hit the port at the right time?

I have another question on another topic.

Why do I see the varied length venturi on the Brucato slides?

Yes , they will both continue to evacuate ( negative wave) until a converging
( positive wave ) section is added .

I can only assume that it's a further use of the "object in motion" rule of physics to try and somehow use the added length on the intake side to make up for the gross difference of primary length of the exhaust conduits .

Only in Canada , Singapore and Oz .
Here is a detailed explanation of this phenomena ....>

Just happened to stop by my buddy's shop this afternoon ... who'd a thunk it ... catered in BBQ ...

Merry Christmas everyone ... !!!!

I or no one said Jon Made Pipes. I said he tried Expansion Chambers ONCE.

Wait...what...conversion on a 4 stroke? Thought the positive wave was timed to hit the 2 stroke port around what, 40* before closing, to keep the good stuff from leaving the party with the burnt? Thought cams and valves pretty much took care of this on 4 strokes? I wish I had paid more attention in Physics class.

**noli** · 12-23-2017, 12:12 PM

.

want to learn about the 4 strokes (as well as the 2 strokes) also....

has anyone tried putting a Japanese 4 cylinder alum car engine, supercharge it and bolt onto outboard mid+lower?

.

Make up my mind , is in out or in in and out in ... I have always preferred the old fashioned in and out ...

I wasn't aware we were "converting" anything either ... ?

How do you deal with the spilt milk of the "fifth cycle" ... ?
