Good god if your car doesn't repeat within a couple thou in similar weather now you aren't winning anyways.. if you guys think these things are just going to show up and run the number you're delusional.. sure they wont be affected by a 30 degree temp swing or a storm front rolling through changing humidity, but they'll have their own challenges to navigate that will be just as complex if not worse than yours.. they don't need their own class
Brad is dead on, there was electric dragster in Phoenix for a while he had the same problems as all of us trying to repeat dead on....Just saying
HAVE THEY CALLED US YET ? THEY HAVE!!!

The technology in a Tesla is way ahead of anything out there As stated before, yes they have to cut a light, yes they have to hook it, yes they have to dial it and yes they have to run the number but the DA, temp, Hum, Baro and grains are out the window. That’s huge in my book. I’ll take the heat when I’m wrong! No big deal and Not the first time either... lol. Just give one of the new cars or even the EV Camaro at Pomona to a great driver and watch what happens.
Raceless in California!

I started racing in 1990 with my 1988 Firebird, EFI since day one. I have never raced a car with a carb......... That being said, few cared I had EFI, in fact, most shook their head and asked why? If you wanna go fast, put a carb on it. Well, this is now 2019 and I still have EFI on that car, plus the car I built for my wife and son. No one complains, we don't win enough!

BuckyI don't think any of us can say we are experts about how electric motors can and will be used in bracket racing. And that's kind of the point. If you make rules after racers have invested in set ups, you will lose those racers forever. it simply isn't fair to them. So the rules need to be specific about what is allowed for controls. Stuffing that genie back in the bottle is a tough thing to do.

I.P. DaileyBucky, you can run a electric car in brackets right now. See a fee at different tracks.

slantzillaAs said before, my biggest concern would be can the safety crew handle a fire if one crashes bad?
Sure, they aren't affected as much by weather, but they are still affected by battery charge, motor heat, and controller temperature.

Why do you assume that they will print time slips? One 100k car makes a 9 second pass and you automatically think it will win every bracket race it’s entered in.

That's the point. It's unwise to assume anything here. They need to be in front of this to some extent with rules appropriate for the electrics.

And what rules would that be?

botmbulbIf you build an internal combustion combination correctly, you won't move through daily weather changes either. Barometer should be your only concern, but it shouldn't move more than a point in 2-3 hours (which would only be about .010 in ET in the 1/4 mile). If the barometer moves more than that in 2-3 hours, you're probably not racing for long anyway. If done right, temperature shouldn't affect you, and water grains would have to change substantially.
If your current combination cannot do this, that is the place to start. Work the current problem, not a perceived one.

Maybe- for the same track on the same day. For any other track on any other day you're going to be changing jets, air bleeds, timing, etc. to adjust for the air. Otherwise, why would you even need a weather station or race computer?
I don't think you would have that problem with an EV.
Just off the top of my head I can think of over a dozen advantages to running an EV and only two or three drawbacks.

Nope. Nothing needs to be adjusted for different air. If the combination is built in a certain way, temperature won't affect it. Then, you only need the weather station to look at barometer and water grains, and it's very easy to calculate what it will run.

SS427IMPI should have clarified: If you're trying to run the same number every pass in different air you have to adjust for it.
No?

Yes, for different barometer and water grains you would have to make changes to run the same number. But, there is no need to do that when it's so easy to predict the ET.

ferndaleflyerBud you need to let the man know that you run an Oldsmobile and they CAN repeat run to run, day to day without adjusting anything---most of the time

So that what he meant when he said "build an internal combustion combination correctly"

AZShould not take a sharp programmer long to make a drag mode. Setup for less than min. ET. WOT= X motor RPM in X amount of time = 1320' in same time every time. As long as the driver can stage the same every time and cut a light it should be much better than a Matty box, RPM chip,traction control or slew rates.
