Thread: engine input...

    I put this in the tech forums but didn't get too many responses...
    I don't know much about blown engines. I was told yesterday (Saturday) at the boat show it is better to build horsepower on the outside of the block rather than inside. And that bigger ci is more torque and that will cause more problems. I have a guy that can build an engine with a 540 ci block that will put out 702 hp naturally aspirated. So my question is, should I go with the bigger displacement with out the blower or should I get a smaller block maybe 509 and get it blown? I also want longevity out of the engine.

    Why not have the best of all worlds?
    Go with a setback bracket and an outboard.

    I've heard good and bad things about blown engines so I want to get peoples input on them. Again, I want longevity and as little problems as possible (and yes I know it is a boat so that is impossilbe). :hammerhea

    Blowers require maintenance. The frequency of this maintenance varies with the capacity of the blower.
    I'm surprised your question didn't generate a ton of great input in Gear Heads.

    Hey brutha, the guy to talk to is Shaken not Stirred, he does more research on engines than he should! Paul Pfaff built his latest engine, it has a Whipple on it and he's pretty happy.
