avon may not have a lot of posts here and you might take him for a newbie ..be assure he's not a rookie player and has gone faster than most on the board with his TAblock powered regal
he pushes his stuff in the Baltimore /cecil area , nitrous out of the hole and 8s is think is where i last saw him
at your level most would say no plate ,
was mentioned on alky injection that they like them because they are using the plenum to distribute a fuel, i believe in them on stock and precision plenums and know somethat have done well with them ...but on my mease plenum i dont run one, keith built them with his own design distribution plate inside tbut mine is open . years ago i was told pull it off at higher hp levels
