has anyone heard or seen any gains from the jl s/m upper plenum for the eaton ? does anyone know of any test results for this mod ? It is a pricey mod just trying to justify or not this mod.
not possitive but i believe that it is made mostly just for the kB blower. i do not think there are much gains to putting it on a eaton. maybe if it is an agressive port it might but i believe it is just made to help flow more air which is need for the KB blower at have boost. someone correct me if i am wrong.
