There are people who don't want their setups known. Nemo and atlplayer are some of those people. I respect it.
I take their word that when we race they are all motor and nothing else. As far as what engine is under their hood, who cares. It's either a b,h,k it's not like it's rocket science
but I think coming on a forum telling someone elses setup is rude without their permission especially when it's people you know don't want their details posted
