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?

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!

Paul, For a small and lightweight turbo I would suggest he take a look at
the IHI turbo used on the Yamaha 650 turbo circa early 80's. A very small
and compact unit.


OOPs, I erred on the turbo description. The Yamaha XJ650T had a
Mitsubishi turbo,
with a tiny 39mm diameter. It was the Honda CX500 turbo the had a small IHI
(I'll try to spell it) Ishiwara Harima Industries turbo. The very small
turbo of the Yamaha, along with a sophisticated Blow-Through carb set made
for a solid and useful motorcycle. It wasn't the highest powered of the
turbo bikes but was quite enjoyable to ride. You can still find one once in
a while. Possible turbo donor?
