Thanks for the good feedback.
We all need to start somewhere, so now i went rather big for all engine exteriors, and yes, the stock pistons may not hold up, but its a starting point.
Im a bit reluctant to just go large on the squich height due to previous experience that another engine got really sluggish this way(dual head gasket with spacer in between), but it was different in many ways, so i am not in a position to really argue against the 3mm squish height.
It will be alot easier to get methanol than to get E85 or similar in smaller quantities, but i need to be able to fuel it on a normal gas station.
Sheel Vpower is what im building for now.
I do not have have the exterior exactly like Jens describes the intake. I have nearly 250mm intake runners that are 55mm at the bellmouth coning down to ø44 equivalent at the head transition. Idea was to get the longest runner possible to gain bottom, and im not so sure after thinking twice that it was worth the effort. Most likely there will be tons of torque before the runner lenght becomes a true adder. Its there now, and im not too fond of it, so its one of the things that is not ticked off as completed. For now, it will have to do.
Exhaust should be fine i hope.


I still have a few options to pick from squish area wise:
Current setup: Tight squish, 7mm band, compression ratio 9:1
Alternative1: Go for tight squich, 4mm band, compression ratio 8,5:1
Alternative2: Use FT pistons instead, and mill away the entire squish band. Guesstimate the comp ratio will drop to 8:1 or so.
Alternative1 is actually nearly no squish at all on the 16V head allready. The head doesent have nearly as much squich as 8V, and when opening the dish in the piston the squish area drops significantly.
@Jens; What does the term "serious effect on normal bensin" mean in this forum in terms of actual HP levels?
