Hooty:
You are going for a record which implys there are some fast people out there that have gone the route of spending the dnecessary dollars to be number one. Seems like fast is a combonation of dollars and knowledge. There are only two high rpm engines made in the USA that should be a natural for high rpm and resulting speed. Jett and Nellson racing engines will give you 20,000 plus of reliable power for a reasonable dollar. They only come in a 40 size with respects to the real high rpm engines needed for you application. Size of the engine will limit the size of your boat, so most of the speed design must come from the boat design, same as the Q-500s and formula airframes. Now, there are always exceptions, they seem somewhat dollar related and are. Your OS 61 is a dog in intended applications and might as well yell at the moon here. If you gotta have a big block that turns rpms, gotta go for the king, the 90 BVM ducted fan engine, good for 20K plus. Quality again here equals dollars, you may find one on e-bay for around $500.00, they are $800 or so new. The OS 91VRDF is also a high rpm engine good for around 20K, but not with the pure power of the BVM, but much cheaper. There is a real art to getting high rpms out of the OS vrdf without burning them up. Chances are you will put more into the learning curve with the OS than buying the superior BVM outright. Again, quality and performance equal dollars. There are some guys in Germany that are hop up artists for the big engines who will make them scoot for a buck, gonna cost as much or more than the BVM in the long run. Recently bought a OPS 60 that is guaranteed turn turn 24 K and up. Thing has 8 induction ports, etc. After looking at the internals of this thing, it sits on the engine shelf. No question that it will blow up, just a question of when! Not gonna risk gear or me or buddys with the thing. Yea, am susre it will give you world record rpm's and speed for at least the first and second run which is what it's designed for. Did I get ripped? I don't think so, the engine will do what it's designed to do (I believe), just a few times. Just trying to give you a little feel for what the record holder types thinking is. Yes, you can do it!!! Get the best information you can and then go for it. In 1949, two 14 year old kids took the nats record for class B in U control with their inovation of a presssured fuel tank taken off the McCoys back plate. Shocked the old guys who really know engines and how to make them run. The next year, they all were running pressurized systems and the kids got blown away. Kids should have kept their equipment covered at all times!!! Such is racing and speed in general. None the less, you can do it. Ron Morrison did!!
