I have a 1985 Corvette, which is rated at 230hp (I understand that that there are now family sedans which could smoke me ). Since 1985, the hp has gradually increased to where it's over 300hp for the last of the C4's. My question is this - how much additional horsepower would be needed to make a noticeable difference? I guess what I'm thinking is this - if I were to go to a 1988, for instance (I think they have 245 hp), I don't think I'd notice a difference from what I have now. What year would I need to go to if I wanted to feel a difference? I'm asking this because I'm kind of doing some long range planning and I don't know if I should go with something newer (I'd stay with a C4) or not. I realize that there were other improvements besides power; It's just the hp I am looking at right now. Thanks to anyone who ventures an opinion!
