They use a wilder zorst cam due to the heads having to flow the gases at nearly a right angle out of manifold. The way i look at it is that with a 4branch and full system the zorst side is flowing better anyway. There are no down points!!!!!!! you can even run more ignition advance with that set up
Sorry i didn't get any plots from Vince on Saturday... it was the last thing on my mind on the day! I will try and get them sorted next Thursday when i go again... but i'll be straight off to GErmany from there, so won't post anything up until 2 weeks tomorrow... And by the way... i've got a set of twin ABF zorst cams to test out when i'm there...
