OK all you rotary heads out there, do I have a question for you. What would it take to make a 13b into a single rotor engine? Why you ask? I have 1982 wetbike (http://www.wetbike.net) to see what I'm talking about) and would like to increase the horse power from 60hp to some where between 80hp and 100hp. So here are the questions I can think of and would greatly appreciate your input.

1) Where can I find blueprints for the 13b?

2) Which rotor housing to use, the front and machine the output shaft to size or reverse.

3) The output shaft will be vertically, will there be a problem with lubrication?

4) What about the ignition system?

5) How many gpm would be needed for cooling?

Thanks in advance.

Atkins rotary makes a single rotor engine.

Talk to them. Or just save time and buy one from them.

 

You'd need to custom make or modify the eccentric shaft. You'd need to have the counterweights redone or possibly leave one off. You'll have to look into that one. You'llneed shorter engine bolts which isn't that big of an issue. You'd use a front and a rear housing. You'll need a custom ignition/fuel system. Your choice on that one.

If you want to do a unique orientation of the engine, you will definitely need to address the oil system. Cooling shouldn't be too much of an issue. You will need to do a custom oil pan or reservoir somewhere else. It doesn't necessarily need to be a dry sump but that might be the best option.

As far as cooling goes, just use the stock rotary water pump. It'll definitely flow enough.

 

I am no expert on this at all but it seems to me like it would be easiest to use the rear rotor housing. that way you could leave the whole flywheel assembly ect intact and just modify the front of the e-shaft to work with the front cover. But im sure your gonna need a different flywheel ect so maybe im wrong.

 

What restrictions are there from just using a 13b as is?
2 rotors are better than 1!

 

well why dont you just do wht im doing

find you one of those bikes,, im getting a F1

sometime next yr im going to start my mockup for an idea id like to get going, not sure if i want to try by myself in marketing, or take a shot at getting mazda to pick it up...

but i just think a rotary powerd bike would kick ***,, wht sucks is.. i had this idea for some time now..and lol i just found out about these babys

 

Suzuki made bikes and snowmobiles in the 70's that have single rotor engines.

Lost tech though, the liter sport bikes would beat the **** out of a rotary bike.

 

lol they would loose if they meet a Norton f1 sport

look threw the site...
besides Suzuki,, Norton was the only one to actually made one,, and make great sells.. i think they made them in 91...

just google

Thanks for the replies guys, I looked at the Atkins rotary, but $5000.00 is a little much for an experiment and besides I've been a machinist for 10 years and it's more fun to tinker. As for using the stock engine too much HP (I know too much HP is never enough) and would tear the 90 degree gear box apart. Dose anyone knows were I can find some detailed drawling to the engine.

Thanks again

on a site all about wankel i seen VERY detailed write ups.. i mean ALL the math work for the housing compared to the rotor
