Furthermore, Disco Wings is not using good statistics. He has two engines one being an MVVS and the other being Evolution. There is no way you could take that data and publish a paper as people would laugh at you. You have to replicate the trial using multiple engines. Maybe the person with the Evolution got a bad one? We don't know. Not every engine out there is going to run exactly the same. An example of this is Dick Hansons Evolution 26 on a pipe. It will turn over 9000 RPM with an 18x6. Other people only get 8700 or so. Who's right? Maybe Dick got a really good engine or knows more how to tune it properly. Take the Super Tigre G2300, some run, some don't. You'd also have to have the same person adjust the needle settings as others may like theirs a little richer. Perform a test using 20 MVVS 58's and 20 Evolution 58's with 95% confidence intervals and if you say that one statistically produces more power than the ohter, I will beleive you. Until then, you don't have a case.
Ben, why are assuming I'm publising anything, this entire post a is aquestion! You post a paper when you complete your research, while in fact I'm doing it right now. I'm sorry but the mere fact that you are talking my findings as publishable material, or even elevating to a paper status is what is really laughable...
The question I asked is that if anyone was able to get higher than 5600 rpm with the evolution 58! The reason I posted this is because I have witnessed 2 Evolution 58s produce 5600 rpm, had a conversation with a guy who also had an EVolution 58 only getting around 5500-5600 rpm. I compared these 3 engines to an MVVS 58 and found that the MVVS 58 was making power. I clearly stated this when I started the post; You either didn't read it, didn't understand, or jumped to the conclusion prematurely.
In fact if you are getting 5600, then WHat the hell, your the 4th person getting the same exact RPM reading. AnydyT says he is getting 6400, so I would like to know his setup, what oil he used e.t.c. Its not a matter of tuning, these people are veterans tuners in the hobby; they all were getting around the same RPM which I find very hard to belive as just a coincidence or tuning issue; like I said earlier, even you are getting the same RPM reading!
I'm not going to perform a test of 20 evolution 58s vs MVVS 58s; If 4 out of 5 Evolution 58's underperform SEVEARLY then thats a problem, thats 80% fail rate in a resonable size sample. These engines need to perform to spec that horizion hobby states, if not they are going to go back, thats it.
In the mean time, anyone considering getting an evolution 58, I suggest they hold off untill we get some more responses on this issue, and it IS AN ISSUE.
