A lot of people have spent a lot of hours on the flowbench trying to find out what works, its not like other heads.

I know of other Mini owners / tuners who have hit 230+whp with the stock compressor to throttle body pipe.

I think your estimate for a head (10-15) is spot on, though there are heads out there what seem to produce a lot more than this.

No new chip, your current air fuel is safe as houses.

Custom tune is good choice i know. If I will have any trip to England I will come to you but is veryvery far.

I know the head is not a simple job, but I will trust my friend who made some engines for rally and he win's in his class. It wasn't MINI but I believe he will do some good works on it. Like I said I am not talking about 30+HP on head. I am a little realistic.

The throttle body pipe will be the simply job here. I have all stuf for welding (TIG), lathes, CNC machines and that stuff actually at home. I will try to do something better then OEM.

What is your opinion which ratio is still safe on that supercharged engine? So If I change head, throttle body, compresor and that stuff will the ratio stay the same? So between 11.3-11.6? What's your experience?
