What is crap ?
20 years ago engines looked like this sports engine and even today there are a lot of people with current highend engines not getting to the laptimes as the topdrivers from then.

We are a bit spoiled with the idea that only nice shaped parts and fancy porting will make a motor fast.

So yes, for our standards it looks crappy but I still think it will be a a faster option for all those RTR drivers and that is the purpose of these kind of engines.
