The water spray idea is good, the other three are obviously facetious.

Tyrell used water spray cooled brakes in F1 years ago (although the real reason was weight. Cars were allowed to be refilled with fluids prior to post-race weighing. Dumping a lot of water during the race gave them a weight advantage)

But - what defines water cooling? If water spray is illegal then can an air-cooled bike race in the rain?

i know of at least one "production" class rally car which had a windscreen washer diverted to spray the intercooler....worth quite a bit of HP I was told.

I still think an oil cooler on the gearbox is worthwhile - and legal - particularly for the longer big circuit races.

I diverted my windscreen washer to the carb through a jet on the 2.3L turbo I had in my Mitsi L200. Ran 10psi with no probs with the water and rattled a bit at 5psi without.

A wet aircooled bucket was quite useful at Taupo a few years ago. Made the same power the whole race.

Himmmmm .... now how could I get a huge amount more crankcase volume??? nope nothing obvious there.

I bet those not so obvious crankcase volume enhancing parts would be an excellent return path from that oil cooler, right?

i'm looking forward with a great deal of interest to see how you manage it with a belt CVT........

Hmmmm I see your point......

Back to the cooling spray, etc. All engines are air cooled, they just vary in the medium that gets the heat from inside the engine to the atmosphere. Aluminium, water or oil, are all just a method of heat transfer and dissipation

Yeah, but we all know what the rules mean, imagine reading, or writing a rulebook that had to cover technical semantics to that point...

I'd rather build a bike and race it.

TZ, Kel and many others on here are capable of building winning bike without trying to get in to tricky shit.

Kel already has actually, that thing is a rocket.

Considering that the road race commissioner considered water injection to be water cooling , I think there may be a problem with external watercooling.

Yeah well said.

4t - 2t .......

OK so you were just curious and wanted to try the 4T thing.



But if getting around town with a 4T is really just not your thing.



Then get real and make that 4T into a H2O 100cc 2T



RG400 cylinder fits ok



Block the lower crankcase off and still have plenty of crankcase volume.

[FastFred]

2t - 4t ......



Remodel the cam chain tunnel and timing chest for the transfer ducts.



Reed valve inlet at the side on the bottom.



Plenty of case volume.



Or you could use a pumper carb and run the reed inlet in through the top.



Because real men don't need 4 Strokes to get the job done.

Never mind what the rules mean. All that matters is what the rules state. Writing a clear, simple rulebook is no rocket science but just a matter of using your brain and a little logic. If the rules are unclear or ambiguous, take advantage of them.

Before calibrating an engine, it is first useful to have some concept of what you are trying to control. The following is a fairly brief overview of the internal combustion engine, which will hopefully give you a basic understanding of some fundamental principles and terminology, so that when you change a number in a box on your laptop, you have some idea of the effect it is having on the engine.

""Fuelling Theory ... Lets start with the theory then. We are concerned with spark ignition gasoline engines here. I am only going to cover gasoline, since Diesel is for trucks and diggers, and alcohol is for drinking and drag racing.""
