Lets start I ma super n00b!!! Not only do I have no clue about motor biking but also no clue a bout engines 2 or 4 stroke in any hp.

Ii got my HT today and started to assemble on my rigorous task of assembly. I noticed if you would drill a hole threw the casing at the point that the motor sprocket meats you could Easily use a pto to put a vacuum cleaner blower fan, to cobble a supper charger together.this would pressurize the intake manifold maybe by 2 atmospheres "24psi" enough to maybe wiggle another 1/2hp of my 3.5 hp engine. dose any one think this would damage the engine or is even possible with a 2 stroke engine?

A Detroit Diesel engine found in most busses used in mass transit are 2 stroke with blower. It needs the blower so it can get the much needed air to make it work. It's a V6 so you know those combustion chambers are huge.In fact,take away that blower and it simply won't work.
The happy time has a TINY combustion chamber with two,sometimes only one piston ring to give enough to make them work. Add a blower or even a turbo and you disrupt EVERYTHING in your little engine.
Think about what is needed to add a blower to an automotive engine. Blower heads. Blower Pistons. Lowered compression. Belt gearing. Gear it to turn too fast and there she blows.
Then you got the cheap Chinese engineering. And the lack of a gear box.
Do you really want to do all this so you can knock one second off your zero to twenty five time?

what he said....

somebody's tried it all....jets have been bored....heads planed....nitrous (yes...4th shot burns a hole in the piston)....

As a hotrod, the little happytime engine will not hold up for very long.

i know a blower is the equivalent of strapping a a high volume air compressor on to a engine witch is out of the question for this application well maybe.....

a super charger is basically a fan that blows air in to the intake and if and onley if you just pressurized the intake without doing anything but

You would need a waste gate, (release excess pressure on throttle down) and much
more. However if you just want a bolt of speed you could use a small bottle of
nitros (NOS) and watch the parts scatter!

The little HT motor is stressed as it is.

A supercharger is nothing like a fan. Air is compressed inside the supercharger, then released into the intake manifold. A supercharger compressor wheel spins at over 50,000 RPM.

Supercharging - It has been done with a 2 smoke but with limited success. The problem is that you are forcing air into the crankcase not the cylinder, it will push out the crank seals and the excess air you have packed in there just runs out the exhaust because all the ports are open at the same time. The best super charger for the 2 smoke is the expansion chamber, it pulls extra air through the engine and then ram's it back in before the exhaust port is closed, free boost. Have fun Dave

PS: The Detroit Diesel talked about still has valves and the ports are not open to the crankcase. The pressure is presented to the cylinder with all the 4 Exhaust valves closed, so you can pack it in. Unfortunately they are a dirty running engine and are on the ban list. And not good on fuel.

Have you looked into the Boost bottles?? That's prolly your best bet. One guy here, graucho, even mixed hydrogen to get the BEST results. Look thru his posts and you're bound to find a pic of that setup.
