Plasma Ignition

About those injectors... I have in cbr 1200 cc injectors in each velocity stack, two 550 cc injectors before turbo and two 550 cc injectors after turbo. Injectors around turbo are connected on above 6000 rpm. Idea was that methanol will work as intercooler and all of methanol injected before and after turbo will be vaporized. Another thing is one 65 mm throttle body before plenum. Then it is possible more freely to shape velocity stacks.

Newton ended to be Warden of the Mint. Probably decimals did help him in that post

Originally posted by geek You have all this experience with the Nology wires.   Would I expect to see any difference using  them on a plug in open air?

I didn't see much difference in open air. Eye could be too slow for that and eye sees average intensity. But if you did measure that braid will increase capacitance that should have some effect. Another question is if that has some real meaning.

Originally posted by Roland Tamaccio .... Mark, I might not be 100 percent current on this, but it's definitely not the fuel. There was a bunch of argument about the limiters, and they might not be necessary at a thousand foot.

You are right Roland, the 8971 uses ignition lead to limit over rpm - http://www.msdpromag.com/pdf/8971overview.pdf Cheers,

Originally posted by geek Do they inject in the low and high pressure areas, or just one or the other?    I am not understanding what the volume of fuel would have to do with a mechanical or electric system.   Are you saying for an off-the-shelf system that they don't offer injectors this large?   I just assumed that the fuel system would have been custom made for one of these bikes.

As a bike based thread I guess I will answer on the bike basis...! All mechanical constant flow, some using fuel timers to regulate supply to the engine, some using old school poppet valves, some using a BDK valve, a very few using a small slider valve (in Sweden), some using a combination of various of the above.  

Originally posted by shmot   Yes, minimum of 50 % nitro. I don't know reason for this. At this year funny bikes were in top fuel class but now there are rumours that top fuel is going to be nitro only. Funny bikes would be in own class with no forced induced nitro twins. We will see when 2010 rules will come out.

The 50% rule is historical. The prize funds are based on the old days of payment per run and the costs of using nitro other than petroleum / alcohol based systems. Organisers do not / did not want to pay the same for a petrol / alky run as they did for a nitro one hence the 50% rule.

Originally posted by shmot There isn't real reason why I should shift to top fuel if FB rules will allow planetary gearboxes and separate clutches. Top fuel is only plan B if bike will be banned from FB or there won't be FB-class when this bike will be ready to race

Sami you will be able to race in UEM FB as long as the organisers take the class!

Hi Ian,

It seems that this will finally converge to something. I will contact after couple of weeks...

Cheers,

Sami
