Grand Prix Hydroplane – supercharged competition! This professional level GP class provides all the noise and excitement you can handle. The 1500 horsepower blown V-8s, based on big block Chevrolet design, make the most noise and throw the biggest roostertails this side of anywhere! Limitations are few; beyond the 468-cubic inch engine displacement, it’s Hot Rod City and up to the ingenuity of the builder. Grand Prix hydros are the biggest and baddest of the bad!
