    And a 288 Schrick cam.

      223whp is about right. We were able to get 217 with a 272 cam and similar specs otherwise. Nice job!

        thats flywheel power, based on the loss curve would be around 195whp, those europeans and their flywheel numbers....

          Can you develop the thought?

            And ported head, but not hardcore.

              Ah. Never heard of "Dynoproject" and did a quick search before replying and gathered it was wheel HP, but after a little more reading this morning, it is indeed "calculated brake HP". FTL

              That Dynoproject calculates brake power (at the crank) where the dyno I typically use is measured at the wheels - horsepower is the ability to move XX amount of weight in XX time, which is actually a derivative of torque (basically HP is a fictional number). HP is calculated by multiplying TQ (in ft-lb) by RPM divided by 5250. This is why when the TQ/HP scales are equal on a dyno, they always intersect at 5250RPM.

                As FF said the dyno actually measures the wheel power and coast down losses and adds them to give an estimate flywheel number. its estimated as the coast down losses are not the true drive train losses as true drive train losses need to be measured under load not coast down which is unloaded.

                this means the wheel power can be obtained by taking the flywheel - minus the losses. outside Europe most dyno graphs are shown at the wheels.

                BTw what inlet manifold and ITB are you using?

                  Great observation. Initially, I was under the assumption it was a Rama kit, but reading back, they have an idle balance screw on each throttle.


                  RHD has actually done some homework, and the more we get into yanking power from these little single cams, the winner is evident.
