E-15 & Fuel inj coming in 2011???

On a related note, NASCAR expects fuel injection to be introduced next summer. The target date appears to be July 9th -- the Cup weekend at Kentucky Motor Speedway.

Why do they introduce these major changes in the middle of the year?
 
Yeh why in the middle , makes no sense , unless they are just going to run a few races with this engine then all the way with it in 2012.

Probably this. Do a few races and use them as tests so the teams can get used to it. Practice is one thing but full on racing conditions is a another animal all together.
 
The Fuel injection subject was mentioned only as an afterthought. I wonder if NA__AR will use mechanical (relatively low-tech) or Electronic (EFI- the type of F.I. commonly used today in American production cars)? As paranoid as NA__AR is about computers my bet is on mechanical.

all I know about the changing fuel blends is when they made a change in the mid 80's and it cost me and other boat owners a bundle changing fuel lines, carb overhauls etc.

I'm thinking changing fuel and adding FI is going to be fun for engine builders/tuners next year!

Keep in mind that street pump fuel is E-15. They probably won't have to to anything but go 1 or 2 degrees further on ignition timing.
 
The process of changing to E-15 & Fuel injection has been in the works for quite some time. By the time that it is implemented it will have been well tested. They've been running E-15 on dyno tests since the beginning of this year. They've been testing fuel injection since at least Aug 09'.

That's the best you can come up with. You can do better than that :D

Seriously, people seem to be making a bigger deal out of this transition than is warranted. How about when they switched from leaded to unleaded fuel. There was a huge difference when that took place yet it's barely a thought today.

It doesn't matter much to me anymore what they change.Cause they going to change it no matter whether I like it or not.I just don't see the need to start this idea partially in the middle of the season?If it's been tested and proven to work the way they want it start using it at the start of the season.

Is not the implementation of a change equally fair or unfair to all competitors regardless of the date.
 
Other issues related to this change.....

Some changes to fueling systems in 2011: New items are in the works to reconfigure the current car's fueling system to that planned for the use of the E15 ethanol fuel blend that will be introduced in 2011. These changes will alter the gas lines, making it more tightly sealed in an effort to reduce the probability of water contaminating the fuel - something Sunoco indicated as a risk in their announcement two weeks ago in Charlotte. The changes to the dump cans will make them look more like the ones currently used in the Truck Series. From the on-site fuel pump to pit road, changes will be coming to ensure water does not enter the fuel at any point along the way. One current catch can man explained the newly designed cans not only fuel the cars at a slower rate - up to a second slower - they will require more skill and precision when connecting the can with the car. Despite the alterations to the dump cans, though, most in the garage do not feel the change to E15 racing fuel is the reason NASCAR is doing away with the catch can man. Instead, most point to efforts to cut costs, reduce the risk of injury, and others are simply baffled at the move.
