Taken from whh site "send in your engine for 6x free dyno runs with printouts all you pay is post each way"

New Dyno in Operation: New Zenoah Findings
For the past 4 years the Zenoah G260 has been the engine of choice for the gas model boater, and it rightfully should be, it is perhaps the finest gas production engine available. When we took this engine on, replacing the G23 (23cc Zenoah) in 2003 we saw our boat speeds increase by as much as 10 miles per hour! The G260 was and is the ticket, an easy to use, very durable, and affordable purpose built gasoline engine for model marine use.

This past January we received our new Dynometer, a State-Of-The-Art engine testing machine that replaced our old analog system dating back to the late 80's. I was very excited since this new Dyno was a �water-break� design with computer interface that would now provide us with very accurate information such as; Horsepower, Torque curve, Time relations, Temperatures, and even a computer weather station to compensate for the environmental changes from day to day or hour to hour or minute to minute.

I myself was a little concerned of this type of accuracy since the older machine required a calculator and paper and pencil calculations based on the individual readings we received from our older turbine/reciprocating machine. I was very interested in seeing the actual results and hoped they were close to what we have reported prior.

The first engine we tested was the Zenoah out of the box G230 RC, a fantastic air-cooled engine that we have been using in the Super G for over 5 years. The results were identical to that of Zenoah's claims. We pulled over one dozen tests and the computer readings were all within a few tenths apart. Zenoah claims that the G230 RC makes 2.88 horsepower at 14,000 rpm's. We steadily saw similar readings of these claims.

The next engine tested was the G260 PUM out of the box and this one really suppressed us, and me to the point to where we contacted the dyno manufacture and started to dis-assemble the machine to look for problems and even re-calibrate. The G260 PUM consistently pulled 2.8 to 2.9 horsepower at over 14,000 rpm's. This is an engine that we were told makes on average of 3.5 horsepower at 12,000 rpm's?

When I took these engines on I requested peak horsepower at the appropriate rpm levels and was furnished that information, but now the numbers didn't match.

We then went on the internet to find the conversion from Kilo Watt (the function of horsepower that Zenoah uses, metric) to SAE, our standard horsepower measurement. When we made the calculation I was surprised to see that in truth the numbers we received and have been using were not correct, yet the 2.9 that the dyno read was�
Here is the proper calculation to make convert metric (kilowatt) to SAE (horsepower):
Kilowatt to Horsepower: Multiply Kilowatt by .7465 = Horsepower
Example: 1.4 Kilowatt X .7465 = 1.045 HP

Now for the good� After checking the machine, putting it back together and spending over 3 hours on the phone with the manufacturer, I started making some phone calls to my engine buddies both in NASCAR and in the hobby industry. My good friend and well known engine builder in the hobby industry, Andy Brown was gracious to talk with me about my findings. With his help he brought up an important point that I overlooked during the confusion of the day. He said think about it�The engine is making that horsepower at over 14,000 rpm's not 12,000, and if this is the case then so be it, the faster you can spin the prop relative to the horsepower needed to do so, the faster you go. He was right, I knew that, but I myself was too caught up in the horsepower hoopla that we have all seemed to care so much about. He concluded that in his 25 years of engine building, horsepower was not the most important thing on his mind, but more-so the ability to turn the correct prop at the highest speeds, or enough power to turn the highest rpm's in transmissions on his world class nitro buggy engines. Now he said you need to educate the people on this subject, and not let them be sold based on horsepower only, especially when the peak HP readings are based at a lower rpm range.

Let me tell you, if you don't know of Andy Brown, in my opinion and backed by his world records in both model boating and success in almost any division of nitro engine modifications, he is truly the best in the business. For the record, Andy broke the 100 MPH model boating speed record over 10 year ago!

After I talked to Andy I spoke with Joe Nemechek NASCAR driver and engine builder, and Joe pretty much concluded the same. I also gave him the results of some pulls with our factory race engines which also showed less horsepower tested on the new dyno. He said you are making a little less power than though but look at the curve, our horsepower was at peak at over 16,000 rpms and a constant at over 15,000. We both concluded the same thing, even though the HP was lower than first calculated the HP at the high rpm range was outstanding and certainly enough to make our customers boats run in the competitive speeds that we were being told by all. As a matter of fact I had customers telling me that they were seeing usable rpm readings as high as 18,000 rpm's, and though I really didn't believe it, with these new findings it is more than likely true. I have always said, there is nothing wrong with surrounding yourself with the best in the business and listen to what they have to say. The day you think you are the smartest guy in your business is the day you begin to go out of business. A special thanks goes out to Andy and Joe for taking the time to help me think about this in a logical manor.

So where do we go from here? I had all weekend to ponder on this and here is my take on this newly found information� Nothing has really changed, only some numbers some lower but the most important one's are higher. Now I am really wondering if there is truly such thing as a 6 or7 horsepower 25cc 2-stroke engine, (that runs on pump gas, normally aspirated) and does it even matter? We now know it doesn't take 5 or 6 horsepower to turn a 75 mm prop over 15,000 rpm's. If it did we certainly would not be seeing the speeds we have been accustom to. Also, say we can make that kind of power, if it is done at anything less than say 14,000 the only alternative is to use a bigger prop, and what good would that do running a 82mm prop on a 45 inch hull, we would have prop torque issues that we couldn't deal with.

In the weeks and months to come we are going to use our new truth telling (lie detector) piece of equipment to make our engines even more efficient and report to you our findings. I have also decided to offer a free service for a short time enabling you to send us your Zenoah or CY engine, for 6 free Dyno pulls, and we will email you and send you hard copy of the results. You will be responsible for shipping both to and from Warehouse Hobbies. Be sure to insure your engine for its value in case it is lost in shipping.

To sum this up, this is not a bad thing. We know OUR modified engines are performing and the customers are pleased. We also now know that horsepower is not the most important thing when modified or in your case purchasing a modified engine, it is the ability to turn the correct prop for your boat at the highest rpm's. This is an age old known fact, that somehow got shadowed by �Who has the highest horsepower engines�. It has been 4 years that we thought that the G260's were making 3.5 horsepower and not a single person or customer has pointed this out. Everybody seems to be very pleased with Zenoah, and they should be, there is no doubt they have offered us a great product, and our industry has profited from it. On the other hand, if I were to let this slide and not educate you of these findings we would continue to go forward and be fooled with false readings. Ok maybe it sounds good if we said that we make a 7 HP engine, heck it's good for sales right? It has seamed to work so far� That's not the right way to progress in anything in life. In business I can be loosing money, but if I were to re-write the spread sheet over and over again, I could make it look like I'm in the black, by fooling myself with factious numbers, I hope you understand what I mean?

Now let's get smarter and in doing so we can force other manufactures to do the same. I am open to comments by customers and my competitors, and I personally challenge other peoples findings to compare against my own. I can be reached Monday thru Friday from: 9:30 am-5:30 pm Est.

Sincerely,
Tony Castronovo
President, Warehouse Hobbies Inc


It's been a couple of weeks since I wrote about our initial findings on horsepower and I do have an update.

I may of confused some of you with the initial report and findings, and after several emails I want to try to explain what I mean about continuous horsepower. Horsepower is simply a rating given and can be used and or read a couple different ways. The formula is very easy just multiply the torque (foot pounds) and RPM's divided by 5,252 and the result is horsepower.

Here's where it gets tricky. You have “Peak” horsepower and “Constant” horsepower. Peak HP is the point that an engine is ran unloaded to it's maximum potential and then the load is applied suddenly. This is the point that the engine is stalled and will make as much torque at the highest RPM's possible for the engines displacement capability. Please UNDERSTAND, Peak HP is not usable HP, and in most cases a engine can operate 15-20% under it's peak HP. What I am trying to establish is the constant HP for our usage. For instance our M5 engine under dyno conditions without a clutch directly hooked up to the machine will be ran up to 18,000 rpm's and then the program initiates and abruptly loads the engine. The result is a Peak HP averaging: 4.6 HP @ 16,000 rpms. In reality this engine can not carry a load of this caliber , therefore the usable HP is somewhere less than 4.6.

Now if you were to do opposite, run the dyno up, rather than down, the same way we run our boats and start this engine and run the rpms up slowly by applying throttle (a load), HP will climb as speed is increased until you reach the maximum HP determined by the physical characteristics of the that engine. This will fall short of the peak HP, because an engine can not run constant at peak HP.

Try to imagine this… You are trying to break a large nut loose with a breaker bar. If you jerk with all your might you will subject the nut to a higher torque load than if you were to apply constant force. (pulling the breaker bar).

We all know that to jerk the bar provides more power but yet you could not sustain this power over a period of time. The jerking effect we will refer to as peak power. And the constant force we will refer to normal running conditions, or your full throttle.

Most manufactures rate their engines using peak HP not constant HP, therefore there is a misconception on what true HP ratings are for our gas model engines.

Peak HP is very useful information for engine builders like myself. When I make a change to a procedure and retest, if the change was for the better my HP should increase.

This is for example only (Basic analogy not considering, type, size, or weight of boat)

For instance; if I find that it takes 4.6HP to turn a 80 mm prop @ 15,000 rpm's and I know a 75mm by calculation spinning at 17,000 will make the particular model boat go faster and handle better, I can change the engines porting/modifications to increase rpm's and though this will effect HP (make it go down, power curve), as long as I have enough power to turn the prop that boat requires, I go faster, in effect we are eliminating the “waisted” torque.

Involving the example above, If we were to put a prop larger than the 80mm you would not have enough torque to turn that prop at 15,000 rpm's. The rpms will now drop due to added load thus loss of overall HP until the engine finds it's new normal operating range. To turn the new “bigger” prop faster more horsepower is required.

I hope this will help you better understand engine horsepower and it's usage. We are working on recording constant horsepower and when we understand our findings we will begin to rate all of our engines using “usable or constant” HP.

lol, so it took Tony almost 20 years to learn that. I thought everyone knew to look for constant hp not peak. I would have thought a guy that makes a living modding motors and such would have know that.

Yes Ken has been saying for weeks Tony had got this new dyno and all his previous hp claims for his motors were proved wrong ,very interesting read.

Thing is it would be interesting to see how other motors rate on this dyno to see what hp they put out in comparrison to what they make on the said builders dyno .Seems like the offers there if they wish to send one for testing .

always been to look at the area under the curve. Ever wonder why a Supra that makes 1000hp runs like **** in a standing 1/4 mile... but runs from a roll like a animal. When you make nothing for HP until it rapidly peaks for a couple hundred RPM, then drops like you shut the motor off... thats not usable power.








And still waiting to see a dyno sheet of the Zen7 that makes a PEAK hp of 7.3 at 18600rpm

peak is a joke term people use to sell motor's or anything else in that matter, every look at watt on a speaker amp peak 1200amp RMS
650watts. same thing. incase your not sure what RMS means it's constant

My advice here would be to use very little written in this post as fact or knowledge. But I agree that it is an interesting read. The conversion from kW to hp is kW/0.7465=hp, (or in europe 0.7365). RMS means root-mean-square. The talk about peak/continous hp sounds like a big missconception, as does the rest of it.

Good posting though, keep it up.

Humble regards

No 2 boats or setups are exactly the same. I tell you what ill offer you, since you want a real comparison...


Come out here to GA with your Zen7 and pipe of choice. I will make 4 passes with my Insane cat with my QD25 & Hotpipe, and Malachi modded 1475/2 prop.. a combo that has been 70.4mph already. After these 4 passes, i will bring the cat in, pull the motor and pipe out, and we can bolt your motor and pipe in... and you go make 4 passes, with the same prop.

If you cant beat my speed achieved that day in those 4 passes, you get back on the plane and go home without your 7hp Zenoah....



Are you game???

How about bring your cat and etc come to Vegas? I will take care a free hotel room for you... Vegas is a nice place for boating.

No need for me to go to vegas. I know what my boat has aleady done with a proven 7hp motor... you obviously want the opportunity to "prove" your [email protected] zenoah can run with a good running quickdraw powered boat, so im giving you that opportunity to prove it with a boat that has already shown it has the setup capable of running 70+mph.

Infact, i really dont even want your motor. So you have nothing to lose and everything to gain by coming here and showing just what the almighty 7hp zenoah can do. You win, you go home with my quickdraw and pipe, you lose... you go home with your tail between your legs but still got a motor you can keep telling everyone that makes 7.3hp @ 18600rpm.

afraid to comparison in Vegas? I just reviewed your "70MPH" video, it's a true liar, your cat weren't even hit 60 in the video, show you speed again by a real GPS reading.

Are you serious? HAHAHAHAHAHA. My cat didnt even hit 60mph in that video? You might want to get your eyes checked, or buy a better monitor... cause the GPS shows 0.0 in the beginning, and 69.1 in the end...and that was one of the slowest passes that day.

But actually... you are right, see i had 2 GPS in my boat during that video... it really only went 46mph that day, havent got it to go any faster yet. How about this, we dont even have to worry about comparing the two motors anymore.... why dont you bring some $$$ and we can gamble on whether my cat runs what ive said it runs or not. Cause i have multiple people who saw what the cat ran, including someone that posts on here.....and its faster with a heat racing boat then you've gone with ANY BOAT [X(]

Yes, I'm. my monitor is 21" big, tell you what in your video, when you were taking out the first GPS by your right hand, it was moving away from the camera for 3 seconds, by that moment, someone could slide a second 70 mph of GPS to your right hand then you showed the second GPS to us....if your cat could run 70, make it run again, I really like to see that real 70 video.

Cause i have multiple people who saw what the cat ran, including someone that posts on here.....and its faster with a heat racing boat then you've gone with ANY BOAT [X(]


"Im not cocky im confident...ill have you tellin me im the best and take it as a compliment"
Yes, I'm. my monitor is 21" big, tell you what in your video, when you were taking out the first GPS by your right hand, it was moving away from the camera for 3 seconds, by that moment, someone could slide a second 70 mph of GPS to your right hand then you showed the second GPS to us....if your cat could run 70, make it run again, I really like to see that real 70 video.

Yup, thats what i did. Dont believe the numbers? Dont wait for a video... COME TO GEORGIA, BRING SOME MONEY, AND WE CAN GAMBLE ON IT.

Maybe so...but like i said, i have many people who saw the numbers everytime i brought my boat in. I made quite a few speed runs with my cat that day, and still had room to adjust for even more. 67.8, 69.1, 69.7, 70.2, 70.2 again, 70.4 were the numbers. Dont have to believe them... cause i have national record holders who saw for themselves


Try copying and pasting the link into the browser... or just click the link from here

Next you are gonna say Matt photoshopped the numbers on the GPS... cause i didnt even make that video HAHAHAHAH

No need for me to go to vegas. I know what my boat has aleady done with a proven 7hp motor... you obviously want the opportunity to "prove" your [email protected] zenoah can run with a good running quickdraw powered boat, so im giving you that opportunity to prove it with a boat that has already shown it has the setup capable of running 70+mph.

Infact, i really dont even want your motor. So you have nothing to lose and everything to gain by coming here and showing just what the almighty 7hp zenoah can do. You win, you go home with my quickdraw and pipe, you lose... you go home with your tail between your legs but still got a motor you can keep telling everyone that makes 7.3hp @ 18600rpm.
afraid to comparison in Vegas? I just reviewed your "70MPH" video, it's a true liar, your cat weren't even hit 60 in the video, show you speed again by a real GPS reading.

Are you serious? HAHAHAHAHAHA. My cat didnt even hit 60mph in that video? You might want to get your eyes checked, or buy a better monitor... cause the GPS shows 0.0 in the beginning, and 69.1 in the end...and that was one of the slowest passes that day.

But actually... you are right, see i had 2 GPS in my boat during that video... it really only went 46mph that day, havent got it to go any faster yet.

I was looking for someone who has a QD 25 HT cat in vegas to compare my zen7 cat then you replied that and inviting me to your state....hey Mart, can you pay for my air ticket and room? LOL

The link worked now,nice flip[8D]
I'm only stating what i saw in the video which YOU posted as proof of your speed.
The second video as well could have been 'planted' too,probably wasnt,but still possible.
The camera started when the hand was already holding the GPS.
Again, it dosnt really matter,it still looked mighty quick to me[8D][8D]

What a fake speed you did? 60mph? I have $$$ to spend, even if I break this Zen7 again, that's fine, Dave would fix it for me...
