Is meth injection considered a power adder
Please explain why you think it is or isn't.
The question is being asked due to new rules in the EFI class at our local track.
one of the new rules is only one power adder.
this is still under review.
This is posted in the FI section also.

Not neccessarily. it allows you to add more hp for the most part. Id think you could get away with water injection but most local tracks can't test your water so that might not work either. I asked the same question for the LSX race.

In general, If you are running a stock or low compression N/A motor on a 50 F day you will lose power.
If you have 10:1, turbocharged motor with 20 psig of boost you have to have it or you will have a grenade on your hands.
I don't consider alcohol a power adder, it just allows you to build a combination that will live with more cylinder pressure.
Kind of interesting that NMCA allows E85.
