Mazda rotary Engines?

[eliot-ness]

Rubbish.

The first Wankel-engined vehicles were NSU cars in the late 50's. Even Mazda's use of them pre-dated any motorcycle applications by several years, as did some light aircraft and snowmobile manufaturers. Suzuki, Van Veen et al got in on the action just as most of the rest of the world were realising that rotary engines were not the way of the future. Yamaha had one in the wings, but noticed that the RE5 very nearly consigned Suzuki to the history books, so it was never released.

Sory but you are wrong. The first use of a rotary engine was on a road bike. A home built engine, designed and built by a guy called Mercer in Bradford, UK and fitted in a BSA frame was on the road a couple of years before the Wankel version. The earliest rotary engine I know of is in the Dewsbury Transport Museum. It was built in the 1920s. The rotary principle from which the engine was developed was originally used as an oil pump, some air conditioning units still use it. Nortons were far in advance of any other rotary manufacturer. They were the only one to successfully use air cooling. Motor bikes were only a small part of the operation. Most of their engines were sold to the US Air Force for use in pilotless drone spotter planes. There are still a few Norton Rotary bikes around. Saw a nice one a couple of months ago in Warkworth and another pretty rough version at the Puhoi Tavern.

I'm not referring to any Crappy NSU rotary engine as they are basically just pistons with a long conrod

Ghost riders 1300cc turbo = 499 HP = A fair chunk of cash.
Rangi's 13BT = Less than $4,000 (In total including the car) and a replacement clutch = 374hp@12psi

Ghosts 499HP busa = scare you shiteless
Rangis 374hp 13BT = boring piece of shite

The 13B is only 250kg.

On second thought's,that can't be right can it ?

250 kg is around 550 lbs,that is cast iron block and head V8 weight.

Maybe its 250 lbs (113kgs)

I was given the DVD with the 499hp Busa.
Any bike that makes a GSXR1000 look like a slug and does 170mph ? wheelies is up there.I think it also had lots of aftermarket parts so is light,200 to 250 kgs wet perhaps.
Maybe flag the rotor motor and build a E J Potter 500 hp Hilborn fuel injected small block Chev powered replica.
Rev it up in gear and get pushed off the rear stand,classic.

I remember reading that a brand called Hercule made rotary dirt bikes, made so much power that they would bend the spokes on full power and had to make trottle stops and also a longer twist grip so you couldn't get the full power.
But their is also going to be a Norton rotary race bike at the classic festive of speed next year in feburay.

Wally Pushky (sp) an Aussie Abbo rode one here in the late 70's owned and built by Roscoe McGlashon of land speed fame. He was contracted to run 3 times each meet with each run more crossed up. Roscoe also rode it at Meremere with an offer also made to a Kiwi to have a try but he declined as his 900 Kwaka was winning comfortably at the time. Mark is now a top Harley dragster jock in Aus.

Therewas also the guy from Aussie with the quick volkswagen powered bike but can' remember his name..Joe ????

There was also a guy from up north who did the V8 drag bike thing here..Mr X ? with a 332 ford Y block along the lines of Pushky/Potter doings...or something like that.

It would be banned now being to dangerous or something...Fun is off the menu,mind you it would help to be a bit troppo being pushed off the stand of a valve bouncing V8.

Quite right, good sir - my apologies. I got "Wankel" stuck in my tiny brain and overlooked the fact that Felix was not the first to build a rotary.
That said, the first rotary appears to have been designed in 1887 by an Aussie chap, and the first patented rotary engine for cycle use was patented in 1895. Neither design was what we tend to think of as a "rotary" these days.

New street-legal Boss Hog has a 504c.i. big-block Chev (About 8.5+litres), launching it like that would be "exciting" eh?

I've found a list of the correct weights of the Engine Blocks:

From Performance Car Forum

Might give you a rough idea.....................

Mazda 12A and 13B 260 (109)
Mazda 10A rotary 224 (20) (Cosmo) (bare)
Mazda 10A rotary 268 (20) (R100) (bare)
Mazda 10A rotary 190 (27) (R100) (without thermal reactor)
Mazda 10A rotary 280 (27) (R100) (with thermal reactor)
Mazda 12A rotary 348 (20) (RX7) (with oil and water)
Mazda 12A rotary 356 (20) (Japanese model turbo, EFI)
Mazda 12A rotary 275 (85) (w/flywheel, t.reactor, no alt.)
Mazda 13A rotary 301 (20) (R130 Lucia - Japan only) (bare)
Mazda 13B race 242 (95) 2-rotor race motor, with accessories
Mazda 13G 3-rotor race 319 (95) 3-rotor race motor, with accessories
Mazda 13J 4-rotor race 396 (95) 4-rotor race motor, with accessories

The middle figures are all in pounds.

To convert pounds to kilograms, multiply pounds by 0.45 kg/lb

The engine I would be wanting would only weigh less than 120Kg's an would put out over 300hp and still be N/A. I would intend on peripheral porting it to obtain 300hp. How to mount it to the frame?

[Motu]

Easiest way would be A section V belt with a pivoting idler pulley - pushing the idler into the belt tighten it and acts as a clutch....simple and effective.I would mount it vertical,ah lah Kenwood blender....that would look cool man.

oh this thread is still going? . .

Make sure you get the hook attachment so you can kneed dough. Or the [K] one, that was always the best to lick as you got more icing.
