WHAT IS THE HYDROSTAR SYSTEM AND IS IT FOR REAL? – Well we don’t know the answer to that but eh book is well written with every detail of the engine conversion described very well and clearly. we can say some one has gone to a lot of trouble in writing this system up and we believe it could have some good things going for it. However we invite feed back if you are inspired to give it a go but as with all things it must be replicated exactly to give a fair opinion, otherwise it is not a HYDROSTAR. The booklet is A4 folded so it is best to print it out and fold the pages and have it stapled and trimmed and you have a good working manual. Very best wishes with this one.
