ok so heres the deal, i have a 1982 honda 50cc moped… i really want to do somthing cool to it. and i was thinking about turbo charging it. but then again how hard would it b to turbo a 2stroke. seeing on a two stroke both the intake and exhauast ports will be open at the same time. wouldnt the boost just flow right thru the intake? or am I wrong. does anyone have any suggestions? ---

this is for deiseld but good info: > Large two-stroke diesel engines are predominantly employed for ship propulsion, with only a > few being used for electricity generation in land power plants.

Large four-stroke engines are > applied in shipping generally only to smaller vessels and to those vessels with special > requirements in power concentration or space restrictions such as cruise ships, ferries and Ro- > Ro vessels.

The first Sulzer turbocharged two-stroke engine in service was a Sulzer > 6TA48 engine in 1946 in the works power house in Winterthur, while the first Sulzer > turbocharged two-stroke marine engines were a 7RSAD76 and a 6SAD72 which both entered > service in December 1956 [2]. > That 20-year gap arose through the fundamental differences between four- and two-stroke > engines.

1. Finding a turbo small enough to run off 50cc engine would be tough to spool enough to get power. I remember some article guy having enough trouble getting one small enough for a 400cc quad. Then again it would need to push much as your feeding that monsterous 0.05L of displacement and two-strokes are pulling/pushing air twice as often as a four-stroke. 2. :tspry: Go from 3hp to 5 or even 6HP! Not only that but a 5lb bottle would probably last most of the day in that thing. 3. EDIT: Thinking of wrong engine series. ---

ask HRK about leafblowers… We had a blower running in my Nissan pulsar, the one that now resides in the woods of Buffalo Ski Club. ---

2 strokes have no oil pan, therefore you would need a separate oiling system for the turbo. Turbo + 2 stroke is virtually impossible because fuel distribution in a 2 stroke, just put a bottle on it ---

we were also tryin to figure this out for intense98rt’s 400cc 2 stroke polaris quad…external oil pump of some sort…cant figure anythng else out for the fuel though…using a k03 turbo ---

2 stroke top ends need no oil. its not fair to say they all dont have an oil pan/oiling system. 2 strokes with transmissions have an oil pump and regular oiling system just like anything else. its just that none of it goes into the cylinder. ---

Curious as to what 2 stroke has crankcase oil? Cause the crankcase and cylinder ports on a 2 stroke are connected. All 2 stroke bottom ends I have ever seen are roller bearing and a lubricated by the fuel/oil mixture ---

Every two-stroke bike I’ve owned had crankcase oil. Completely different from the oil injection system. I’m with BIGHANDS about the premixing, leaves less to go wrong that way. ---

I’m with BIGHANDS about the premixing, leaves less to go wrong that way. i dont know much about bikes, but i do know a lot about 2 strokes since ive been working on marine motors for a long time. i know that some marine motors have oil tanks that hold the oil(gets mixed through oil injection). (Oh and i agree, i have an oil injection system but its not hooked up and the alarm for it is disconnected. i prefer to mix). But i dont think that the oil ur thinking of is neccessarily crankcase oil. Its either tranny or its a resivior for the oil injection. ---

All 2 stroke bottom ends I have ever seen are roller bearing and a lubricated by the fuel/oil mixture go to a motorcycle dealer, ask the salesman to show you where you put the transmission oil on the 2 stroke dirt bikes. (bad example, salesmen are usually morons and probably dont even know). but anyways…i know how a 2 stroke engine works, ive rebuilt them so many times i cant even count. im saying not all have no oil. yes they dont use any oil in the cylinder/crankcase, but if they have a transmission ie: like most motorcycles do, they have a fully sealed and OILED transmission with an oil pump. and if you read what i wrote carefully, youll see i made no mention to it having ENGINE oil. ---
