    that gives you 112.5 cfm @10" which equates to not a bad, but nothing great head, flow figures alone wont tell you how much power you will get, but from 2.0 assuming all else is pretty good your probably see 190-195bhp

    Re: 2 litre pinto flow figures

    widening the the short turn Will pick up flow especially at high lift, but i dont remember at what point you start to gain flow, but i do know if you not going to use port filler or a 1600 head its the way to go on a race head, it was a trick showed to me by dave walker that he used to use on his race heads back in the 80's

    Re: 2 litre pinto flow figures

    cant find any pinto figures, but these are 3 bmw m10 heads which have many similarities to a pinto, second and 3rd set have had corners of short turn reworked/lowered all @10" cam/valve lift is critical, extending lift on 3rd set of figures gave much more flow, in fact one bmw head i got airflow upto about 140cfm, but needed 2mm more valve lift than was possible

    Re: 2 litre pinto flow figures

    thought i answered this last night at home maybe my laptop didnt upload the post?

    anyways you have enough flow for 200 bhp perhaps more, but that doesnt mean you will see 200bhp, it also looks like to get the most from it you need more valve lift, so perhaps the port shape needs revisiting?

    IIRC its for drag racing, so perhaps a kent RC31
