The boost numbers dont matter at all since its going on a motor with 3 times the displacement.
But for HP it will move enough air for 300 whp. Unfortunately this will more likely be a power reducer than a power adder on a v8. I would be looking at at least a 65 pound turbo, with a real big exhaust housing.
Well, come to think about it, if he is going to use 2 turbos, which is very common on V motors, it doesnt have to be so big. So that 14b could be good for 600 hp if used in pairs. The exuast side is still going to be pretty restrictive though. Assuming the motor is a 5.7 liter, thats 2.85 liters per turbo. Yeah, way too small. Go with something meant for large displacement motors.
