I am looking for a very small and light turbo for a two stroke 300cc
and 600cc rotary project. I need it to be light, I know a
supercharger would take power from the engine butI also know that
most turbos are heavy or very expensive. I can make my own
supercharger from aluminum, but I am worried about the powerit will
take from the engine to compress enough air for the boost. Seems
that weight of the turbo and complexity of waste gate and all are
one evil,yet no hp taken from the engine for operation is a plus.

and that the hp required to run the supercharger is a evil,but very
simple ratio drive belt and  no waste gate assy is a plus.

Which one? advice and recommendations? David Jr.


You got me there. I recommend


"The Turbochargers" how-to book, written by Hugh Macinnes, will show
you how to select and install the correct turbocharger for big or
small horse-power gains. If you want more power, a turbo may be the
solution you are looking for and this book will definitely help you.

This book also covers turbo design, sizing and matching. Controls,
carburetion, exhaust, ignition, intercooling, marine and
high-altitude applications.

And unlike other DIY turbo guides, this one covers much more than
just car engines. You'll find information on truck, diesel,
motorcycle and marine applications, to name a few.

The /Turbochargers/ how-to guide is the most comprehensive
turbocharger book available, and you will also find information
related to turbo suppliers and kit-maker addresses.

If you want to turbocharge your motor, this is the guide you need!

Don't forget that a two stroke will pump almost double the air that
a four stroke engine will of the same declared displacement. Also
in that size range for the displacement, the turbo will be quite small.
No where near transport trucks or industrial equipment size and
weight. The center section is one area of mass but the other is the
turbine housing. If it was cast from titanium or made of Inconel sheet
the turbine housing would be much lighter and reducing an 8 pound
turbo by 2-3 pounds.
