When is a motorcycle engine, not a motorcycle engine

[MotoMax]

A strange question I know, but it's one which I need to ask because it concerns the use of an engine I want to use for a motorcycle streamliner.
The engine in question is the Hartley V8 made from two Hayabusa engines jioned with a common crank and crankcase.
Does the fact that it uses Hayabusa parts, be good enough to satisfy the rule or would it be the fact that it is not made for any car or motorcycle, but could be used as a purpose biult motorcycle engine be good enough?
Or is it a none starter, i.e. am I going to cause a deal of controversy even considering it?

Please help,

cheers

There have been entries that have used 2 coupled Hayabusa engines, so I think this is no different. I am not familiar with making the Busa into a V8, but love the fact that someone wants to do it. However it would not hurt to write to the SCTA M/C chief inspector inspector and ask.

Good luck.

I think the engine must have originated in a motorcycle.  You could not buy a V-8 Hayabusa motor, ,so it would not be a "motorcycle" engine.

The question was pretty thoroughly discussed a while back, and the example of the V4 in the Bub 'liner was brought out as a potential "non-motorcycle" engine -- since it was never available stock in a bike.  But wait a minute -- the first time the engine was ever installed in a vehicle - it was put into the #7 bike.  So therefore it IS a motorcycle engine.

The Ack bike runs a pair of 'Busa engines -- but they're separate, not twinned.  And a few cars run 'Busa (and other brands, too) motors -- but those are cars.

For the absolute word please check with Tom Evans or Van Butler.  But I think I'm right here. . .

Seemslike there was a V-8 bulit in England for hillclimb cars using Yamaha 1000cc stuff some years back also -a CAR motor, too.

The Manning engine is a kinda chicken/egg - egg/chicken deal. Just re-read the SAE paper on that project and it was certainly purpose - built. The result of  Manning meeting the gentleman at an SAE event and the topic of a LSR engine thus lead to the project.

In drag racing , from a statement by Terry Vance, the "Harley V-Rod" drag race engine was designed in - house by Byron Hines. I mean in Colorado,  not Milwaulkee or Zuffanhausen.

IMHOP same deal.

page 112--  7.H.18       page 125--- 7.J.5    7.J.6   7.J.9   7.J.10    the only exception i see is U F and U G  and omega  ----   UG and UF  are streamliner only and omega is A-PS and Streamliner only   thats the way i read it                          willie buchta

I think that was the point. Who all remembers the KB2? Ran as a motorcycle for some time. Only KB Hemi powered bike I ever saw.

Actually the BUB V-4 has been in two motorcycles. The first streamliner to have the engine was Tenacious II and in 2001 Rocky set a one way speed of 297 mph at Lake Gairdner Australia. The Seven Streamliner would be the second, having been designed to only carry the BUB V-4.
We currently have multiple engines in development, including a V-Twin version of the V-4.
I would imagine that you will be seeing this family of engines racing for some time at the salt- Eric

The Hartley is a non production based engine that uses Busa heads.  I haven't spent too much time on the bike rules, but if the class rules require a stock block, you'd be out of luck.

I saw the factory mule Lotus 7 with the Hartley in it at a car show a little over a year ago - they're based here in Wisconsin.  Yeah, it's expensive, but man, it is a jewel, and it sounds like a F1 Cosworth Ford.

well?..... somebody help the guy out!....personally i was thinking the same thing in that I thought that engine choice was unlimited in that class? ?.

Yeah you're right , I'm a car guy, on the other side of the world ....and I wouldn't know peanut butter from shinola anyway.............

Thanks for your advice and help so far, has anyone got Tom Evans or Van Butler's contact details?

I wanted to do something different and a twin turbocharged V8 busa appealed to me.

I thought this form of racing was rule less apart from the safety aspects of course.
Where else can ingenuity and lateral thinking be encouraged........surely we don’t want all future streamliners to be exactly the same?

The 4 current MC streamliner contenders use vastly different engines.

Max posted several months back about an English motorcycle effort using one of the British Hayabusa V8 engines from Powertec. I think that they are planning to be at the BUB. Go to General Discussion and look for "Yank Spanking" and you can see the engine specs and also a great pic of the "motorcycle" Pretty neat.
