I guess a visit is out then!

Long shot here but roughly where are you located?

I left comments on the videos you sent. It is hard to believe that so many people for so many years can't get it through their heads about the exhaust pressure is the key. Myself for included for a couple of decades! As far as your design not looking like it would be able to start but should...

I used an Aerodyne turbocharger that had precision high speed bearings that were oiled with a wick from a small oil reservoir. Instead of a waste gate it had several airfoil style blades in a circle around the driven turbine wheel that could be adjusted to direct the exhaust gases at different...

I feel that you would have difficulty starting the engine the way it looks. The crankcase with reeds acts like a one way valve. I put a fitting in my crankcase that monitored only the positive pressure in the crankcase by putting a reed in the line to the gauge and saw a pressure of 7 1/2 psi at...

I'm not sure I am following your idea, you wrote; Now, let’s suppose we want to turbocharge it using a turbocharger, and we place the carburetor before the turbo (in a draw-through configuration). We then adjust the jetting, ignition timing, and compression accordingly. "After that, we...

The very first experience with turboing a two stroke was at a snowmobile grass drag. I was still like 99% of people that "knew" turbo'ing a two stroke wouldn't work because any boost pressure would simply exit the last to close exhaust port. There was a race sled with a turbo mounted at the tail...

In case anyone is still following this thread, I did a real stupid thing last fall and nearly died. I have a formula/champ style one person tunnel hydro with a moderate v6 2.5 liter mercury on it. They all have power trim and trimming the engine angle is critical for controlling the bow lift...

BTW, in order to match the block to the new crankcase and wind up with the crank bore being round and sized right I did the bore on a DeVlieg jig mill. Yours being 50% longer will be a little tougher. I could be wrong but I think when the engineering guys see what you are asking they won't be...

No cooling mods at all. In fact the one to one gear case off a 45SS johnson race engine (stronger than the "D" Merc) had such a big water pump in it the engine wouldn't warm up so I had to re-route some of the water back to the river to get sensible engine temp. I really hope you aren't planning...

I'm an old school machinist, sine plates, rotary tables and such. When I was buying my first Hurco machining center when the owner of the shop I was dealing with stepped away, I asked the twenty some year old operator how difficult it was to learn how to operate it. He said he could teach a...

Not the perfect engine for adding HP. The long somewhat frail crankshaft I feel was at the edge in stock form. Either a V-4 or V-6 is a much stronger unit. The small inline four cylinder Merc thast I used had the front half of the motor (crankcase) that supported the crank and took a lot of...

What was the advertised HP of your inline six cyl?

When I told a motorcyle dealer that had a turbo on his bike, that I made OVER double hp at 14.7 psi boost he sneered and said I broke the laws of physics. I told him to visulize a 500 ci engine with a small lawn motor carb on it that would be running in a very high vacuum and making very little...
