is you or is you aint ------------------------------------

this thread is to find out if you can run a car motor in a motorcycle--i say you cant except in UG and UF streamliner class---and here is why---PRODUCTION--there is a 3000 cc limit---MODIFIED--same 3000 cc limit---Special construction 7.g.9 engine: Any single or dual combination of motorcycle engine is permitted---Sidecar---same as special construction---Streamliner 7.h.18 engne:Any single or dual combination of motorcycle engines permitted---the only exception i can find is  7.J.12  CLASS UG AND UF--any recipricating engine which uses the otto cycle may run in streamliner category only
    i think that covers it if im wrong or if i left out anything please let me know --- thanks  willie buchta

Well, as soon as you put the engine in a motorcycle, it becomes a motorcycle engine right?

Well, you could destroke a Boss Hoss -

mcrat   wrong    7.j.5--7.j.6--7.j.7--7.j.8--7.j.9--7.j.10--7.j.10.1--7.j.11----shall be comprised of major parts and componets primarily fo use in motorcycle engines.

The BH wouldn't classify as a production motorcycle?

As if there weren't enough questions in the GT and production classes, now I'm reading bike rules!

I primarily can't think of anything I haven't seen with a small block Chevy in it.

no bike motors in roadsters

the engine size maximum in production is 3000cc----------

there is a front engine roadster that runs at el mirage that has a motorcycle engine-------------

Not wanting to belabor the point, and I do question the viability of the BH as an LSR bike, but is destroking not an option, or is the reading of the rule such that the engine must be of a production displacement?   

What I am seeing in the Boss Hoss is a production motorcycle with a pushrod engine and a ton of development work done on the heads, with a shortend stroke, as potentially a hot ticket.

the maximum cc is 3000 thats about 180 cu. in. that would be a very short stroke for a chevy motor  willie buchta

[McRat]

It's kind of a moot point.  Unless you are talking F1/Indy engines, DOHC bike engines (or certain 2 strokes) make more HP/liter than any other engine in their displacement ranges, so putting in a car engine would add weight and drop power.  But it is interesting that they worried enough about it to make a rule concerning it.  Perhaps they were worried about snowmobile engines perhaps. 

[willieworld]

mcrat  there are 5 motorcycle classes thet allow over 3000 cc and allow 2 engines --so if car engines were allowed you could run 2 blown big block chevies in a sidecar bike   hmmmmmmmmmmm  nah  ill stick to the harley  willie buchta

[McRat]

I'd think you would give up too much frontal area with the big V8's.  Keep the engine size down to a "human" sized cross-section.  Two Turbo Supra engines perhaps (I6)?  That would get you over 2000HP and have a small cross section. 

[willieworld]

and about 375 mph---see how easy that is and we didnt even spend any money LLLLOOOOLLLLL   willie buchta

Yes you are right, and some cars have run faster than some "sidecars" and your point is..?  Better keep one engine running before you choose to implant more than the one you have now..
