Arrow Racing GTR .21 Engine Thread
#31
I personaly run the OS 2060,or Alpha 2081,alpha pipe seems to have better low end power and more runtime,but i have to do a back to back test to have solid results,as far as runtime is concerned,I think 10mins is an easy target,using 7mm OS Speed restrictor and 25% Meccafuel.

to be honest,i just avoid saying things that may proove to be wrong,all I can say is that my GTR has more pinch than my Vspecs at the 3 gallons mark.All I could get out of my Vspecs was somewhere near 4+ gallons,so lets see what happens.. :-)

Well got a reply and they will be sending me an engine to test. So look for some test results sometime in the future here. I have high hopes for this engine. If it is what they claim it is "and at this time i have no reason to doubt them whatsoever" it should be a very nice and long lasting engine. An engine that performs like or even better then a Vspec, that doesn't wear out a crank pin in 3 gallons time would be one potent racing mill!

that will last longer than the now discontinued O.S. V-Spec
engines Adam. The crankshaft in my AB Mods JX Ninja engine
is still in great shape, after many gallons of fuel. Still, it would
be nice to know that there is a better one to replace it with
when the time comes.
Oh yea, no disappointment here. That's just my $0.02 about
it.

I'm sure it would be but at the end of the day it is what it is which is a complete rip off of an engine that was designed and made by OS. With you being in the industry and having worked hard to develop your own dyno and in a sense legitimize the product that you have made in the mags as well as the service that you offer I'm a little surprised and I think disappointed that you would want to associate your self and your company name with a company that operates in that manner. Just my $0.02 for what it is worth.
I don't own a engine company, i modify engines for the public of ALL brands. I will modify and test any engine on the market and i will be honest as to what i PERSONALLY think about them from my R&D. I'm not loyal to one specific brand of engine or biased in anyway shape or form as that's not my job or what i do in this industry. So please do not insinuate that im doing something wrong and discredit me for simply wanting to test an engine that is hitting the market. As in reality that's all there is to it, im just testing another engine thats hitting the market... nothing more, nothing less. I do not see this the way that you are taking it it seems.... and im honestly and sincerely very sorry you feel/took it this way.

WOW.... Please don't put a twist on this like i am doing something wrong by simply testing an engine. From reading your post it seems to me that your coming off very rude and trying to discredit me for wanting to test an engine?? Now THAT is disappointing to me that you would come at me in such a manner and insinuate that im doing something wrong by simply doing my job. My job is to test engines and modify them to perform better for the public. So honestly i don't see how me testing this engine as i do ALL engines of ALL brands wrong in anyway. It's no new thing that engine companys loosely copy or try and improve on each others designs all the time. Do you not think the JX .21 is not VERY similar to the OS Speed? Although made by OS and labeled as a Mugen engine its still a VERY similar engine design and a very good one at that! I didn't see you attacking me when i was testing those engines when they hit the market.... And that is just one example as there are many engines that are just like the JX is to the OS speed. The RC engine world is no different then say the gun world for example. People copied off what Glock did 20+ years ago and are still improving on the design to this day and doing it with great success! Same with the Mauser K98 most all your bolt action rifles are made/based off that platform.

At the end of the day morally we all have to decide how we want to conduct our business. People always seem to fall back on the OS/Mugen example etc. forgetting that the difference is that Mugen contacted OS and had them develop an alternative version of and existing engine for them which they purchased from OS, the company that designed and developed the original engine. This is again completely different than a company in Taiwan copying someones engine design, producing it their self and putting their own name on it.
The fact that this may or may not happen with cars or tires all the time still does not make the behavior any more palatable. Nor I should say should it make it any more acceptable to those of us in the industry with companies that invest our time and money in the development of our products. I've watched what you have done over the years with the development of your dyno etc. and this has taken time, money and a lot of effort, something that I feel you should be congratulated for. I also have spoken in the past to some of the mag people you were involved with and they indicated to me that you also sold some of them (and I was also thinking about buying one a couple of years ago). If a company in asia copied your dyno and sold it for 1/2 the price and called it the Y-Dyno I would be sitting here saying the same thing about how that is not correct and have the exact same mentality about defending your product. Now if the Y-dyno was a proprietary design and something developed in house by those people or you licensed your design to them, well that would be a totally different thing.
The bottom line is that whether we realize it or not providing any type of support to these type of companies and their products legitimizes their actions. Something that morally I think that we should have an obligation not to do. At the end of the day a fake OS engine is still a fake OS engine. Just like a fake Rolex is still a fake Rolex and a fake Mona Lisa painting is still a fake Mona Lisa painting no matter what type of spin we put on it.
On a side note also I'm not attacking you, I was just voicing my feelings on this. As mentioned I've watched the stuff that you have done over the years and although I've never spoken with you in person I have a lot of respect for what you have done including in my opinion developing the first legitimate dyno system for micro-engines. You are a prime example of the fact that if you have an idea and are willing to put a lot of effort, time and dedication into it you can pretty much accomplish whatever you want. I said I was disappointed because to me companies like the one we are now discussing represent the exact opposite of that mentality, spend zero time, effort or dedication just buy one of the better items that you can find and copy it. Is this really something that we should be supporting even if in the end the product works?
