My Feedback: (3)

Your not going to find an answer and realistically there is no point if you did.

The power output from many motors is hotly debated (and argued).

If you have an application where your looking for the best motor then it might be a better question to ask (and also ask why). To just get a list of HP and weights for a number of motors will not be any more helpful than a series of props, their pitch and diameter will be at helping you select the best prop.

Rio 51 (reinforced)
And Apache 55

good moded 26 for rio and a good moded 28.5 for the 55 will be plenty

hi evereone, i was hoping someone can help me here, i have a 56 apache with a 26cc stock zenoah, it has a 644 carb and a 3 inch 90 degree stianless hedder with a speedmaster 2 1/4 inch aluminum band pipe, i have not been able to get the rpm`s up on her, i started to tune the pipe at 13 1/2 inches inward to almost 12 1/2 inches with no luck, the engine is new carb is new plug is new, stinger drive is adjusted up for rpm, and i am running gulf full syntec oil, everything seems to be good, is it maybe pipe tune, i would sure apriciate some good input, thanks

What prop

ratballs26

abc 2814/3

ratballs26

other guys in the stock class run abc 2914 and 2814 props and they dont seem to have this problem

ratballs26

this is not a fun boat, strictly racing, i need max out of it

sorry i dont want to mislead anyone, the 2814 and 2914 props i use are modded, downsized, and heavy cup for salt water

Jackal1983

Does the hull sit very wet in the water??? You got any videos??

You tryed lifting strut out the water and angling the it up slightly... Less area of the prop in the water. Have you tryed a 2 blader???
Has everyone else increased compresstion?

All those engines weight about the same (+ or - 6 oz.)with the exception of the QD35 and the BZ 28 and of coarse the four bearing engines slightly more than two bearing engines.

For a 2" band to tune on a 3" header the water coupler is up to the bend without even the pipe holder. The clutch, long pipe and small diameter extension and muffler after the stinger may not be helping.

If you measure that pipe around the centerline to the REAR of the band I am thinking you are longer than it should be.

If you were just allowing the header to push up in the pipe without cutting off what went in past the inner o-ring then you wouldn't be able to realize benefit of the shorter pipe.

thanks for the response guys, yes my drive is tilted up to get most of the hull out of the water, and the problem with all these things is that i run in stock class and they do require a muffeler however if you notice the extra welding to the end of the pipe i removed the internal stinger from the pipe, i agree the clutch will not help but what i did with it is a little secret, the guts has been weighted to form an extra flywheel what this does for me is keep my rpm`s up out of the corners i have tried it without the clutch also and i do see benifets with it, the thing is before this engine was rebuilt i ran a steel pipe with the length being the same and it ran like a beast, but the pipe got rotted maybe due to constant salt water, daniel are you saying that this should be what it looks like ?, i am willing to try to squeez every bit of rpm`s out of the enging, this measurement will bring me in from exhaust flange to end of band at 12 1/4 inches

tbaysal2000

And did you find a solution finally?

Did you try it with the rusty exhaust if you would get the same "beast" rpms?

ratballs26

yes i did, thanks, the rusty pipe is actually a hanson 21/2 band and it works great, and it turned out to be a rusted bearing, they were new but got rusted after one weekend racing
