I was looking at the class descriptions for the IDRC and they use the phrase "Power Adders" what is this defined as?

Im assuming one of the "Power Adders" could be a FI system? If so does a twin turbo count as one power adder or two?

 

twin turbo counts as one, nitrous counts as one, supercharger counts as one, i think thats about it, i havent read the rule book for a year though

 

What class are you looking to run in?

 

None, was just curious because I read articles and stories and I realized that I dont even know the difference between most classes so I decided to learn.

 

yup dmoto is correct.
power adders are turbo , nitrous, and suprcharger. most classes you can have upto 2 power adders, but can have 2 stage nitrous or 3 stage nitrous and count as one and twin turbo and count as one. i guess better explained as 2 different types of power adders.
