Because they are at WOT for the entire race! Lol…seriously though, if they needed the extra control (cough..F1 racing…cough) you would see EFI setups in NASCAR. No, it's not the only reason…I'm sure cost too has a great deal to do with it.
I don't post up here very often but this thread caught my eye.
I run a 327 10.8-1 comp AFR 185 heads 2.02int 1.60 exh, big cam (won't reveal specs LOL) Victor 5.0 intake, 80MM TB,30lb INJ, Anderson PMS and a bunch of other related crap.
with this combo put 408hp 385 tq to the rear wheels. Runs 11.02@124 N/A
Switched over to Victor JR intake, Quick Fuel pseries 750, same ingition as before,no other changes.
With this setup put down 425hp and 420tq (have not been to the track yet, weather down here sucks!!)
This car sees street time but is mainly a track car. No real big diff in drivability.
Why did I do the switch to carb?
Well I grew up tuning carbs and it's what I know. The EFI was nice but I can feel the car pull harder up in the higher RPM range. I shift @ 7200.
Obviousley (sp) I don't care about mileage.
P.S. when it was EFI it was tuned by the leader in EFI tuning for NMRA. name withheld.

kind of the point us carb guys are trying to make
on a side note....i use to be a hardcore EFI guy and use think of carbs as "controlled fuel leaks" lol

Yeah…but you can't directly relate a NASCAR's budget to that of the average car guy….nor can you relate the budget of the average F1 team to that of NASCAR.
Just a fun tidbit of info…I do believe Ford used the same EEC IV computers used on the mustangs for their F1 cars. I kind of gives you some insight as to how versatile fuel injection can be.
Very nice times and hp. How streetable is the car? Have enough vacuum for brakes? What kinda suspension are you running?
Your right nascar has ALOT more money than any given combined number of us on this board! So.......why dont they use efi?
NASCAR is like any other sanctioning body, they make the rules for the race cars. EFI is probably barred by a rule of one sort or another. Some local tracks even bar the use of Cleveland style heads - it's an unfair advantage.
NASCAR is a perfect environment for carbs: flat out, minimal time spent in mid RPM range, and fuel consumption is a secondary consideration.
Take an endurance road race like Le Mans and the environment is perfect for EFI: varying speeds from a slow turn to a flat out straightaway, lots of time spent running up and down the RPM range and fuel economy is important to limit the number of pit stops.
