CONCORD, N.C. – By the time the 2011 racing season gets under way, the only place to find a carburetor in the Sprint Cup Series might be in NASCAR’s Hall of Fame.

Officials said today that they hope to replace carburetors with fuel injection, and have been testing potential systems with an eye toward making the change as soon as possible.

“We are in the process of the development and the testing and have been for probably six or eight months," ” said Robin Pemberton, vice president of competition for NASCAR.

“The easy part is to just build the fuel injection system. The thing that we need to put into play is how are we going to regulate it, and what’s going to be fair for everybody?”

NASCAR is one of the only racing organizations that continues to use carburetors in its series. Fuel injection is a more accurate, and efficient, way of delivering fuel into the engine. It has been around since the 1950s and has been in place on all passenger cars in the United States since the late 1980s.

Pemberton said some Cup teams have already been developing and working with systems with the expectation that such a move would eventually be made. Some teams, Pemberton said, “do have track time … on their early production or early prototype fuel injection system.

“So our goal is to shoot for 2011,” he said. “I think that’s pretty aggressive. “We are pushing hard."

WOW ! PROGRESS ! Now what about that Pontiac Aztec lookin thing you call a Sprint Cup Series Racecar?

Does anyone know how injectors will work at a "restrictor plate"track? My husband asked me! I barely understand how carburators work.

Restricting airflow always decreases horsepower so that doesn't necessarily have to change. Overall it's going to be a whole new ballgame though. There's no way their going to be able to keep engine displacement at 350ci, they'll have to decrease it to 200 or something like that. Might have to be a V6. Policing is going to be harder potentially too.

My Crystal Ball sees Nascar issuing The computor boxes at the track which will have a Rev-Limiter to control speeds at the Big Tracks.
After the race, Nascar will collect the boxes.
They might let the teams have control over the injecters---for fuel milage vs power.

#2 With less air in they will either have to decrease injection duration or oriface size. Other wize the engine will run too rich. Mileage is also a factor as we all know.

NASCAR wont be using electronic fuel injection like you have on your street cars. They will be using mechanical fuel injection which has been used in stock car racing for years now. Nothing on these engines will change. We have been using MSD boxes for years and they all have chips in them so that the engine wont rev over a certain RPM. That is determined by the team since all engines top out at different rpms. This is basically a way of saving fuel and making the switch to ethanol.

Okay, IF it is a GOOD mechanical fuel injection, it will be okay. Otherwise we have enough DNF's now with the simple Holley Carbs. Don't need more electronic crap to go Kapooie. (Is that a technical enough term for you all?) . . LOL. . . I STILL prefer Holley carbs for anything, but then again I am old school, and think they even LOOK much better than any EFI out there that I have seen. . . But I agree they do make the engines more effecient when designed and used properly.

JBBIGROD "Otherwise we have enough DNF's now with the simple Holley Carbs."

Huh? How many is that, or are you just spouting off what you believe, i.e. an opinion, rather than facts?

Come on, just how many Holly carb failures has there been in say the last ten years.

Why, why, why ? Didn't they learn with the wing? Keep your grubby hands off the sport, ok? Just when I give Nascar credit, they pull this lame stunt. Carbs is one thing that SETS US APART FROM OTHER FORMS OF RACING. If it ain't broke, you know the rest.

It's about time that NASCAR adopts fuel injection. Using carborators in this day and age is just ridiculous.

Won't it be harder to get the motor running if they run the tank completely dry with EFI?

I like the idea, fans won't notice anything different, and it will give crew chiefs a whole new area to 'cheat'.

Mechanical Fuel Injection has been in racing since the 50s. Teams cant cheat because the system has no wires or electronics. The one team who will benefit from this change is Jack Roush, He is an expert on Fuel injection where other teams dont have his expertise. He tunes all his WW2 engines himself and they all run fuel injection.

Number 8, I didn't say it was BECAUSE of the Holley carbs. It is BECAUSE of the electronics. NOW IF you add EFI then you double or triple your DNF's becasue of electrical problems. Bad enough now with wires, plugs, switches, batteries, etc., etc., going wrong all the time. . . . The Holley carbs are very good. I didn't say they weren't.

Obviously it is for you, number 10, since you can't even spell carburetor. LOL. Have you ever raced with one?. Built one???

Jack is hands on with everything, including his race cars. Doing the final tune-up checks on them too. . . And WHO says you can't cheat because of no electronics? I would think it would be easier that way. With electronics NA$CAR could put their own monitoring devices on each car. And also the controls to limit them. . . .BUT the BIG cheaters will still try to find a way.

They are not using EFI. They are using the same fuel Injection we are running in the DIRT, and USAC Series. You cant cheat with it.

Everything in both mechanical or EFI systems that get the fuel into the engine which is the pump, the valves, and the injectors are all mechanical but in EFI systems the injectors are switched on and off electronically by the EFI control electronics. And with those electronics you can sneak in some sort of traction control. That is what NASCAR doesn't want. This will also be a new deal for the engine tuners because to get the maximum ratio of fuel to air varies from track to track because of the altitude from the west coast to the east coast. Also you have to compensate for changes in engine temperature, air temperature, engine speed and load, and ignition timing. This will separate the good tuners from the bad tuners. If you watch drag racing you would see that races were won and lost because of a engine running to lean or to rich. Jack Roush will be the sole beneficiary of this if it happens.

I doubt IF Jack would be the SOLE beneficiary for very long on ANYthing that NA$CAR mandates. The rest are no dummies either, they will catch up very fast, especially Chad and company. . . . I am sure Penske and Ganassi are well aware of what it takes to GO with Fuel Injection also.

NASCAR has been running electronic FI in the Grand Am sports car series for years so they know how to police it. to get rid of the restrictor plate they should use the Grand Am engines at those tracks because they are about 500 HP and that can be regulated with the computer.

The only way that NASCAR could use a Grand Am Engine at Daytona and Dega is if they issued it at the gate. That would be a great engine because it only produces 50hp over a plate engine and it gives you great throttle response. But you couldnt let the teams take it back to the shop because they would find a way to modify it.

all NASCAR has to do is issue the computers at the gate. NASCAR tears down and chassis dyno checks the top cars engines after the race now so they would catch any one with more HP. they are more worried about traction control than HP increases.all the rest of the racing associations have given up on trying to police traction control because all the cars will have the same traction control so all things are equal. NASCAR has to put forth a image that the little guy racing has the same chance the big dogs do so they have en ought cars to fill the field but now the little guy knows no matter what NASCAR does to try and even the playing field it is not going to happen. this is why they are not going after the "start and park" racers like they used to

Kapooie is a great word. maybe the start and stoppers can put it to us.

Why is fuel injection considered "progress?"

MOTORMAN - "this is why they're not going after the 'start and park' racers like they used to." I'm confused here - how did NASCAR "used" to go after start-and-parkers?

MOTORSPORTSPHOTOGRAPHY - "It gives great throttle response." Why is it such an obsession with people about throttle response? The sport's history has shown the drivers don't need it.
