What's the scoop on fuel injection? I thought it was to come out in 2011. Maybe test in a partial season. And then no more talk. this is from racer.com;
"NASCAR vice president of competition Robin Pemberton says that the sanctioning body is on target for introducing fuel injection systems to Sprint Cup racing for 2011. He added that NASCAR is also close to finalizing its plans for the use of ethanol-blended fuel.
"We're still looking at the fuel and what ratio, percentage that we will use when we get there. That has not been locked down yet," Pemberton said. "We're still working with the teams and engine engineers. The fuel injection is – I would say it's close to on target, and we've had some changes in the last 90 days, 120 days. Really, it's about trying to get a level playing field for everybody.
"We've set out some parameters, come back, met with the teams and made some changes, and they're off testing. We should have some more answers probably in the next 21 days or so. But I'd say we're on target hopefully for early 2011 – but it remains to be seen. We can't do it and screw things up. But things are moving along pretty nicely right now.
Pemberton said that while NASCAR was attempting to have both greener fuel and fuel injection in place by next year, competition requirements would trump any timetable.
"Our goal, when we set out, everything was to happen in 2011, and where we land with the percentage of ethanol has not been determined yet," he said. "But we have teams that have been running on the dynos with some 10, E10 and E15 and all the way up to E30. But for the most part it's been E10 and E15. We'll let you know when we come to that. Right now there's a lot of work, so I can't sit here and put a date to it. That will be detrimental to the sport in general, so we're still working at it."

I also heard that McLaren was the frontrunner for supplying the fuel injectors. Nate Ryan had an article stating that McLaren is looking to get more involved with NASCAR.

me thinks it aint about specifically fuel injection itself,, but rather every manufactor has a different intake, plenum runners and ideas where to place the injectors. and most throttle bodies are in the front of engines. wow can we have ram air? shall we also have drive by wire or shall we have cable driven accuated throttle plates? ...those dilemmas and differences me thinks are the problem. and surely not some kind of weird distrubutor (actually me thinks a mechanical distributor would not work at all). go totally electronic i say... just like what we drive so the technology benefits us too. a coil for every spark plug,,..a digital signal could control the high voltage spark. no more switching spark boxes. the only control the driver would have is turning off the rev limiter near the end of the race, we already have that.
all the Engine Control Management could be the same. cant hide traction control in a stand alone ECM. there are things like O2, tps. map, maf. iat, iac and another dilemma ..fuel pressure, but them too could be standard..nascar rules you know.
quick starts after red flags..
benefits would be running 14;7 fuel air ratio behind the pace car and 180 in the turns. no lean or rich cylinders. in the shade or in the sun. humiity high or low. watkins glen or homestead. and one eye jack wont have to look at spark plugs so much.
very much like plug and play.
just imagine..the LS9 has over 600+ HP and still can get 20 miles to the gallon. your mileage may vary..
NASCAR was even late on radial tires...
speaking of the LS9/camaro what a great engine/car for another IROC series. fail.. ut oh  LS9 has supercharger ..dang
can you tell i like it?
