youre confused with what brian is asking, because you dont know brian, or anything about brians intentions in the other 2 posts youve made.
Brian wants turbos... a turbo, like a roots, twin screw, whipple, or centripital, is also known as a blower. What Brian is asking, is how bad the lag is on a turbo V8.
Brian, keep in mind... its still a V8, but now it has extra shit on top of it. Its still going to shit and get initially, but then the onset is going to make things that much better. Lag is one thing you do NOT have to worry about.
