NASCAR takes 'really big step' with fuel injection - Oct 19, 2011 - NASCAR.COM

"Gentlemen, start your semiconductors!"

That probably won't be the command given at the beginning of next February's Daytona 500. However, it might be appropriate, given NASCAR's decision to require fuel injection for Sprint Cup engines beginning with the 2012 season.

After ruling the roost since the Kennedy Administration, the iconic -- and museum-worthy -- Holley four-barrel carburetor is finally being put out to pasture as NASCAR's fuel system of choice. The Cup Series is joining the computer age, and that means engine builders and tuners are trading in their wrenches and wet flow benches for laptops and software mapping.

This should make things more competitive.

Might make custom tuning a more "mainstream" concept too! I honestly did not know they were still using carbs.

Neither did I. I don't follow NASCAR but I saw this link on another forum and figured I'd add it over here since there are members here who do. And I figured it might be a tad bit relevant.

This does not surprise me with nascar, it is really becoming a joke to me. All the cars look/sound the same & are not anywhere close to any body style you see at the showroom.
The "Win Sunday Sell Monday" went out the window years ago, when Pearson/Mercury, Petty/Plymouth & Yarborough/Chevy went by you could hear a difference & see a difference, now you have too look real hard at a STICKER on a car to see which MAKE it is supposed to be. I miss the days when they pulled a couple cars off the line & made templates & let the CHEATING/MASSAGEING begin.

They nascar keeps hollering safety, shoot David Pearson told them how to make it safer years ago "cut the width of the tire to 1/2 of what you run today & give them the same 2-3" spoiler we ran & lets see who wants to go fast". Speed will always be the biggest safety factor.

OK enough of my stupid rant....but I think nascar has been shooting themselves in the foot for years.....toyota PLEASE

LOL...

I love the idea of going EFI, it really opens up a whole new era of Nascar. However, from what I am told the teams will not be allow do do any of their tuning, and Nascar will have full control over it.

What a waste of good technology.

No, they are able to do their tuning but NASCAR will limit the amount of data they can collect to bring in the competitive aspect. Naturally they'll start out very conservative and carefully advance so they aren't 300 miles into a 500 mile race and something overheats or gives out.

It was just a few years ago that they went to unleaded gas......and just this year they went to e10.........
