The thing is Karl, we can only offer advice from our own experiences and knowledge limited or otherwise... This is of course how a forum works, we learn from each other.
None of us have the knowledge that you do so you are always going to laugh at some of the things we say because you know better!
Regards your questions, your obviously suggesting that if you want over 100bhp per litre a lower CR than 9.0:1 is needed....
But the CVH turbo is only 81bhp per litre so why is the CR so low?
I did not know that a lower CR will generate more torque low down, why is this?
Of course not all tuners agree that a lower CR is needed, take Stu's CVH for example, Jamie has managed to produce over 200bhp per litre with a CR of around 9.0:1
