Short pipe High RPM or long pipe more torque?

Whats your in put!!

Torque gets it moving HP Keeps it moving I was told.

Torque you can pitch prop more.

Rpm take pitch out

Both ways you can get same speed rite.

Thats what i have noticed on the small pond so far.

More torque seems to help in cornering.

So im looking to you all how to set motor up for torque.

Longer pipe I know what can one do to the motor.

want to run the motor like a diesel lol.

More POWER Scotty is the saying.

truth is, as fact as that is above.. the pipe needs to be correct for your setup.. I have made MUCH more power with a short pipe then long.. but the real deal is the combo was right.

If you are struggling to get what you want.. try a different pipe or prop.

The long and short of it.......

It will be fun to see the answers you get, more importantly to see if any two boaters can agree! Your seeking the Holy Grail and what every boater wants to find, the perfect balance between torque and rpm while achieving winning speed.

For me, I try to keep it simple, longer pipe to start, lean on your pals for the right prop, creep the pipe in until it won't pull it in the straights or corners, back up just a tad from there. Then starts the insanity of toying with props to improve on what you've found. Try some different pipes, they all have different torque characteristics. Then and if you still not happy and your pockets still have some jingle left, motor mods, every motor builder will have different theories on how to build torque but the goal at this stage is to try and achieve higher rpm and horsepower, most mods start with opening up the intake and fuel/air flow passages and finish with intake/exhaust timing tweaks to compensate for the other internal changes.

Sometimes frustrating while you battle through all these variables but if you enjoy the challenge and the endless changes, one day you arrive at the promised land and when you bring your boat back to the dock, you turn to you pit guy and you both just stare at each other and say, what the heck was that?

Boating, that's why we do it! At least for me it is.

I concur thank you sir

like mike said.. each is different.. yrs ago i used to use torque motor long pipe big dia prop.

now rpm motor short pipe smaller dia prop.. results.. about the same. alot has to do with your set up.

kinda like top fuel.. they all have different ways to apply the clutch. it is what you make work to get you the win.

i will say this.. if you are struggling a torque pipe will at least get you going. then you can proceed from there.

years ago I could not get a consistent launch with my 20 boat.. it was about a 50-50 that she would go. I shortened the pipe and BANG.. went every time.

Odd as this might sound the pipe was not at all happy with my timing numbers and prop.. I pushed the pipe in and it was a new game.
