I attached a graph for comparison showing Thomson's 427 Supercharged engine (from Mayhem) with one of Thomson's 442 cubic inch LS7's (from Corvette). Besides the power curves pointing out the very obvious, it does not begin to show the differences in driveability. (not sure how to place picture in post)

Both these engines make great power, run on pump gas, etc. - but with the SC engine, there is no 'special' instructions needed to drive it (other than be aware when applying throttle!). The NA engine continously reminds you what it's all about - and has some driveability characteristics that are not ideal.

I like an agressive cam and loping idle as much as anyone, but once you've experienced the overall package of a well done positive displacment blown engine...... well, it makes it hard to be satisfied with anything less.

Great info.
