any blower guys out there[how much boost?]
hi i have a 434 sbc with eagle crank&rods, je pistons,plasma rings,alum top proline heads[72cc 235 intake runners,208 160] 10/1 comp. not really built for blower but want to do it anyway. just purchased a v7 ysi vortech making 21psi on a 9/1 comp sb i want to underdrive blower just to get some driving in until i can have motor combination changed to blower application. what do you think would be the max boost i can use wth my existing motor? thanks ken
