I am actually the co founder of JAG RC, we have videos on our site. We don't have spacific pictures yet but we are getting closer to a point where we can present them. It took us almost a year to get from an idea to a actualy working unit. The engine is tuned as you would normally run it before the nitrous is injected. We are seeing massive power increase, I don't have numbers to put on it yet, currently we are working on a dyno so we can do just that. As in any performance increase with an engine (Like porting it, or running hotter fuel ect...) you are going to see more engine wear, however what we are finding is it is not extreme, pretty normal actually. We have not destroyed any engines by injecting nitrous, in fact I replaced the piston and sleeve in my M16 and ran for another few months before I decided to go with my Hyper .21! We are using custom nitrous bottles, they are similar in size to the CO2 style cartiges. We are finding a bottle will last between 15 and 20 seconds which is a whole lot!!! As far as frost in the engine we have not had issues with that at all, we did initially have an issue with freezing our valve system shut though. We have since worked that out. We are moving along at a good rate right now, things are looking good. But we are still in our test phase. We are sending out test units soon, just to make sure everything functions with others as it does with us. Also we would like to get some outside reviews.
