    Default Cam profile/grind

    I was wondering if there is a difference in a turbo cam vs. a blower cam profile/grind... or are boosted engine cams about the same?

    Horsepower determines how fast you hit the wall. Torque determines the size of the hole you make.

    Blower is mechanical and involves a parasitic loss of power, the turbo uses wasted exhaust byproduct to boost. Duration and lift must be manipulated to optimize both systems.

    In other words they take two entirely different dart boards.

    See, that's what I know about turbos. I always thought you used the other hand to throw the dart.

    To give you a straight up answer with out the other "stuff" Yes a different grind would net you a better build! Talk to a real grinder and run it! No offense meant to anybody but if the OP is going turbo and a "button" maybe a grinder can work with him on what will work best for his combo! JMO!

    Ok, I wanna high jack this thread for a bit!, No denying crank drivin superchargers cause a drag(loss of crank power to run), but? doesn't an exhaust restriction also cause a loss of crankshaft power? Im not saying the same cam grind should work for both. Just that they both cause some kind of HP loss on an engine that were pushing-pulling them without the positive effects.

    What are you saying. Having a cork jammed up the ass of an internal combustion engine might have some effect on the HP output
