They are very low boost machines...and most of the time they are on 'cruise' level of power and not take off power.

Most carbed turbo cars use a ‘blow through’ set up – if you apply pressure to the input side of a carb it will meter the air just the same way as stock – so the mixture will remain the same.

They can change the carb jetting to whatever A/F they like and you can datalog the O2 also.

Which brings us back to my reason for posting and original question, especially now knowing that they were running "modest" boost for a race motor.

What was this head they were running that seems to be the key to this motor and its power numbers on LOW compression and modest boost???

Shouldn’t you be out cross country skiing and shooting stuff? Especially where some Norwegians can see you?
