Nascar moves to EFI next season
Welcome to 1980īs
How much power would you be looking to pick up from the switch on the R07?
Will we see finally ITBīs and really making the most out of these engines at a professional level?

For safety they will likely restrict airflow still by either mandating throttle body size or using restrictors still. So they likely will make the same power levels as they currently do.

They will most likely do what ASA as well as other series that use injection do... the officials will issue the team a computer... at the end of the day you will be required to turn it in and will most likely be issued a different on for the next day.. Restrictor plates are done similar to this at Daytona and Talladega. I wouldnt look for any exotic TB set ups.. thats not NASCAR'S style.. And as far as the timeless debate about the cars...people who do not know why the cars are the way they and could no longer be safely production based are ignorant about the sport

So put cages in them, racing seats, and harnesses with fireproofing etc. and limit the amount and quality of fuel so they arent overly powerfull. Then maybe we could have some actual sports cars in the show room. Its not that hard to come up with a solution. They shouldn't be called stock cars if they wana race race cars. Dont get me started on this subject you wont win!

A carburetor works very well in the narrow operating range that NASCAR racecars run in, and is so much simpler than an EFI system, there is no real advantage for any team to switching to EFI system...
NASCAR do not want to see power increase, they want to restrict the power, and to level out the playing field, the EFI systems will enable them to control this more precisely.

Its not going to be ITB's or anything exotic like that, think more along the lines of TBI.
The stuff I saw being tested at ECR a few months back used something along the lines of a 4150 throttle body with the fuel injectors very high in the runners (the engineers were complaining to NASCAR quite a bit about injector placement...last I heard they were playing around with injector locations, which are also NASCAR specified) Intake manifolds remained largely similar to what they are currently using.
Power levels are also remaining pretty consistent.....
The transition to EFI is largely for marketing purposes. NASCAR is working on a 'green' kick. This is another part of that, just like the ethanol blend they went to this year and dropping leaded fuel several years ago. They are also trying to lose some of the stigma that NASCAR is 'stuck in the 60s' to try to market more to a younger crowd. They are trying to keep the transition as seamless as possible in the performance department.

I totally agree with the point brought up regarding EFI.. its nothing more than a marketing ploy.. Bringing on more costs to the teams at a fragile time is a poor idea...

Why don't they just put a speed limit on nascar then everybody runs 195 mph unlimited power just limited speed. Pavement pounding is just boring when all you have to worry about is wind resistance or tires. Next thing you know they'll make all the drivers talk on an open radio channel throw in some politics then BAM instant reality sport that city folk and women would watch.
I think motorsports that take real serious skill are rally racing or short course off-road you just roll it 5 times flip'er over and drive it back to the pits.
If you've ever watched LOORR and not been excited you may be dead.

I know its a totally different formula but F1 engines generally mount the injectors above (yes that right above) the ITB horns! If you see a vid on you tube you can see almost a could of fuel forming above the ITBs! Also seen similar things used in rally and race engines.
Again talking about F1 here but the FIA are putting some pretty green ideas forward for alot of racing these days. Obviously Deisel has now become comon place in prototype style racing. WTCC is now looking to use alternative fuels.
personally its a move i would like to see!

I think its a great idea, but i do not think they should hand out the controlls like they do with the resitrctor plates. Ford chevy dodge and toyota are all going to require different fuel requirments. I think they should have a company develop a box that has limited tuning parameters and then let them run what ever tune they want. At the same time all these teams are always looking at the grey areas in the rules to get an edge, so the battle to controll them will be a little more difficult. But its also a good thing cuz it will bring more jobs to the industry and to working americans who will now have to sit in the dyno room all day. I think its really cool they are doing this only because how loose liped NASCAR teams are compared to F1. The changes in camshaft design, piston and ring design and manifold deisgn will all change beacuse of this. I have alot of friends in almost all the engines shops and hearing and seening the changes will be cool. Now they just need to get rid of the flat tappet and go with rollers.
