One magneto solves all , yes they slow down but anything over 300 mph is ok. No new parts to buy plus more spare mags
.
Easy to tech, no meters needed,eyes only. Half the spark plugs and wires to take in&out between warm-ups &rounds.
Back to 100 % ( most ran less than 95% anyway), and the pump size / blower speed will be controlled by tune-up. No rev limiters to screw-up and shoot the blower off, back to different combinations and tune-ups. And a BIG bonus, the cackle will be back ! !
Let the tuner or the driver hurt the engine ,not electronics. Drivers can lift when it noses over.
Now they are Nitro Pro Stocks, all run the same nitro, blower speed, compression , gear ratio, wing angle ,etc ,etc.
You tune by head gaskets and palm pilots.
Plus everybody will start out with new tune-ups, the semi trailers full of data by the big money (multi-car) teams isn't as dominant.
Yes the old guy tuners from the 80's will have a small advantage,but the cars, tires, and clutch discs are different now, plus the blowers are much better, maybe you wouldn't have to strip them every run.
Go back to air timers only ,no need for computer geeks chasing wires, you can't easily have traction control without electronics.
