For my Aussie friends, I think this should be a new thread

You sir have surpassed me, both in ambition and talent!

It depends on set up and type of compressor used. Superchargers give smooth power delivery as do Twin Scroll turbo's. Large single scroll tend to Lag then an almighty boot up the arse. This would not be the best set up on a race bike but where talking about fitting a turbo to an already powerful engine. Small turbo on high compresson engine or big turbo on low compression engine. When i say large or small we are talking in pressure rather than psyical size of the compressor itself.



I have personally never found them to make a big difference.



Would love to see GP bikes experiment with a few different engines though.



If I had it my way they would all be running 20b rotors

A happy Scotman, your makin me feel hameseek for the mainlandn Berry

No ?? Ive read several peeps not liking Twin Scroll because its too linear. Most people who want a turbo car want it for the violent boost. This can be tuned out though, turbos dont have to lag or be violent.

Can you imagine what a Turbo gp bike running anti-lag would sound like. Damn i reckon that would sound better than the cube did !

The modern turbo diesel mercs and bmws are totally seamless, the only thing you notice is the amazing torque.

Running 4-7PSI?



They would have to completely re-design the engine to safely run a turbo, lower compression etc Strapping a turbo to an already high comp engine only ever ends in tears.

Exactly mike. So it shows this technology can be used in racing and help to drive down costs.

Andy roo asked for ideas or solutions, this is mine. Would love to read others but i fear some only want to talk about you know who.

Depends on the level of boost. My car engine is low comp and runs about 1.4 bar, other engines run higher comp but only 0.8 bar. I think all of this will just make the racing interesting.

That's not get totally hung up on turbos though. What about supercharging ?

I dont have a lot of experience or knowledge regarding supercharging, but the smoother power would be a bonus.



However having a belt as an integral part of power production has never sat well with me, they just seem susceptible to breakage?
 
The problem particularly for prototype racing is that they have to restrict the performance in some way as the circuits and human physiology have limits, and wsbk is on track to approach those limits as well at much less expense, albeit with motogp developed technology. Even without competition in terms of bike performance from wsbk, I take kropotkin's point that an open slather smaller capacity formula as proposed by the likes of jerry burgess would be even more hideously expensive and heavily engineering based.

They dont have to be belt driven. I think thats more the case when a supercharger is fitted as an extra to an engine rather than on that was designed to be supercharged.

I dont know but i doubt aircraft use belts to drive superchargers.
 
Ah ok.



I would love to see different engines, high strung NA engines VS turbo VS Supercharged.



Give them a peak power limit and rev limit, anything in the middle they can work out for themselves.



If the limits weren't overly high engines could be finely tuned state of the art prototypes or well tuned 'production' engines.



Sure the guys with the most money would find a way to dominate, but the variety alone would make me take more notice.

It would make it a very interesting series and affordibal for smaller tuning firms to compete with the big boys. I agree there should be a power or rev limit to keep it competitive.

This should keep the Flammini brothers happy as it would be more prototype than production. I cant see turbo bikes being homologated anytime soon.

We had from memory Gpz 750 turbo, Suzuki HN85 Tirbo, Honda CX500 or 650 turbo? never really caught on with road bikes and insurance went through the roof if you mentioned the T word

As long as the limits where feasibly reachable it would be great, an entire grid of bikes with different engine characteristics but the same peak power with different torque / power curves.



The factories could still throw millions at their bikes but the smaller companies and outside companies (ah la red bull) could build a bike that has every chance to be competitive.



Cars do the same thing in Aus

There is a museum near me called "Sammy Millers". If you ever get the chance to visit the New Forest in England give the place a visit. They have some weird and whack gp bike from yester year including turbo, v8, rotory ect. The days of true prototype. The days when blokes like that kiwi bloke Britten? with his creation could compete.
