Don't be fooled by marketing hype?. And then you start about the latest crank and such?.
You might want to take a look at the crank a Capricorn engine uses, it's pretty different compared to a Flash crank.

Everything I stated is from personal experiences, also the things I stated about the RB engines is something shared by many others.

First time I ran my lab E-01 WC during saturday practice at a round of our nationals every driver was amazed about the ridiculous speed this engine had.
This includes guy's running factory engines and A-class (non-retail) Nova Flash engines, used of competing at EC level.

Also when reading through your sig (Novarossi America) I don't think you have an entirely clear view on this.
