If you download some of the PDFs if you can find them there is pictures of engine outside of the ships where you can see the true size of them.

But i do want to know if anyone has gone and looked at a lawnmower or something and thought wow i have a superchargered lawn mower.

if i have time i might try and learn how to write a small website and put it somewhere. The idea of climbing around inside an engine fraks some people out.
