Basically the silicone insert is simplifying the production proces with as result a lighter crankshaft. I run my modified 5T engines with no silicone insert just as fast as any other high end engine containing all kind of crap gimmics.
Roelof's N5T is good! Just as fast as anything out there, you can take budget engines and playing with port area/timing and crank timing, some fuel flowing and you can gain a lot! But you need to do the research first.
