I don't know which kind of dyno it was but he said he had to set the roll speed or something before he did any pulls and he did a couple of low speed runs and adjusted the dyno a few times before the real pulls. He also said the rwhp numbers were calculated at a 25% loss. (which seems high, I thought it would be 15% since it is a manual 2 wheel drive car?)
The rockers I bought were 1.5 because I thought the heads would have to be worked so the pushrods didn't rub/bind?
