Been trying to experiment more with supercharged engines lately 
I’ve still got much to learn though, so any tips are welcome 
Why undersized (less than max bore/stroke)? Why on earth cast heavy internals coupled with a billet crank, and all at +8 quality? It’s expensive (billet crank on +8…), heavy (“heavy” components, duh) and not very durable (cast components). Why no supercharger control? And why 1001 cc, instead of, for example, 999 cc? In any system (racing classes, taxation) with a displacement threshold at 1 litre this puts it right at the very bottom of the over 1 litre class.

I wanted the block to be lightweight, which is why I used magnesium. Magnesium isn’t as strong as using billet aluminium, so I compensated for that by making the engine variant smaller to improve the Block PD, and it allows me to up the capacity in the future if need be
Did try using forged parts at the beginning, but the engine didn’t really seem to need it (It’s true that the Piston PD is pretty high for comfort, but the reliability tab doesn’t seem to indicate that the pistons are experiencing any serious issues)
Didn’t really seem to need that as well, the CS never seemed to be under too much stress
My chief engineer told me not to worry about that, treating the inspectors to a good meal will surely make them ignore 2cc. Hope he’s right though 
(I also wish that we had at least an extra decimal point when choosing the bore and stroke, would allow for much finer control over the ratio while keeping the desired capacity)
A set of forged components all around would be a more realistic choice, for once.

While leaving room for future larger variants makes sense, the weight/strength… does so less. Using a smaller block of a heavier, but stronger material usually leads to a lighter engine that can deal with the desired power.
But… the billet crank is overkill, as evident by the displayed limits vs the engine’s parameters. Meanwhile the conrods and pistons are stressed. Forged crank would be enough, and forged conrods and pistons would be lighter and stronger. This could also allow dropping some quality, to save costs.
As for the supercharger control - IIRC it improves efficiency too, and maybe some other stats? IDK, I rarely use superchargers. But it’s usually beneficial to use.
That you can actually do! You can input more numbers after the decimal point in various dimensions, just click on them and type numbers on the keyboard.
Although I really don’t get the point of using such an odd capacity, other than “pretty number”
