I'd almost think that if a person runs electronic they should mandate a switch to cut the pump power in a event of a hard impact . We r racing for fun here and we don't need someone hurt or killed from being burnt up. Just my opinion

GOOD***SOMEBODY BESIDES ME IS THINKING ABOUT ELECTRIC FUEL PUMP CONTROL!!
It is not all that hard. Speedway motors sells a switch that is controlled by oil pres. When the oil pres drops below 12psi, I think, it turns off the fuel pump, Might even save a motor if oil pres. drops off all of a sudden. We use the factory ecm method that is a little more complicated but works well also.
Racing is dangerous. I don't think Doug Wolfgang was using electronic injection when he got burned so bad several years ago. Safety is not a good point to use to promote mechanical injection. People spend money for a mechanical injection unit because they believe it will give them an "EDGE" period end of statement. This may or may not be true. I used to sell people DUAL EXHAUST because they could tell their dad or wife or whomever "well it helps my gas mileage" That was back when gas was 35 cents a gallon.
I don't buy Tim's deal that you can only push so much fuel with electronic injection. Want more fuel install 90 pound injectors. In "Indy Racing" or "Formula 1" Price is not the object, this being said why don't they use mechanical injection. The reason is that the computer is so much smarter than a human being who only has two or three adjustments to make (pill, spring and another spring or two). The human can get the mechanical injector to kinda of idle, Run like hell WOT, and maybe if they are lucky not to load up under caution laps. With the electronic injection a person can if they want adjust the fuel requirements for every kind of engine demand in 250 rpm increments, try that with mechanical injection.
With the Kawasaki we are running we not only have a main injector in the throttle body but we run what is nown as a "SHOWER INJECTOR" that injects fuel into the inlet horns from several inches over the air horns themselves. This actually cools the charge air and allows more fuel to be burned by the engine. Try that with mechanical injection.
The people in Il. are trying to make a growing group of mini sprint racers and they are doing a pretty good job of doing it. They want to try to make a level playing field for everybody. If everyone agreed with them then they would not be doing their job.
The guys that built up all the hype about mechanical injection to sell them are also the guys that lead Il. to not allow them. We have been racing a long time. We have beat a lot of guys running mechanical injectors and been beaten by them as well. The group in Il. have not been around cycle powered cars for all that long. If it was me I would say bring on the Englers, Kinslers, and Hilbourn and lets race. We are all looking for an "EDGE" If mechanical injection is the "EDGE" for this year so be it. Put a good driver together with a hard working set up man and you can sell anything. If it worked for Steve and Karl it stands to reason it should also work for me don't you think.
One of the best things about "IOW" is people can talk with one another over great distance like between Blomington and Peoria and even New Albany and let the other people know how they feel about the way things are done. If anything will bring about National Rules it will probably be because of the "Indiana Open Wheel". It is much better sitting here hammering away at this key board than sitting in an old rented hotel meeting room and listening to people cry about why it is not a good idea because it will slow them down they think. They never really say "slow me down" but that is what they are thinking.
