      Is all of it attributable to the chamber shape, or can a compression increase be responsible for some of the reduction?


      increasing volumentric efficency also lowers advance requirements

        ~240hp from 2 litres is pretty solid, and not exactly screaming it either!
        "Where can we get hold of a Vincent Black Shadow?" "Whats that?" "A fantastic bike," I said. "The new model is something like two thousand cubic inches, developing two hundred brake-horsepower at four thousand revolutions per minute on a magnesium frame with two styrofoam seats and a total curb weight of exactly two hundred pounds."

            Cool. Figured the denser charge would have to increase burn speed.

            Hey tony, if you gave this more cam could you get it to power out to 8.5krpm +, or would it be into the diminishing returns zone? (I guess as this is a roundy roundy engine it needs a solid under curve area though)
            Adjustable cam gears for 1FZ-FE now ready for sale - 10 degrees advance/10 degrees retard. Suitable for all variants of 1FZ-FE.

            (adjustable scissor gear for changing separation angle between the intake and exhaust cams coming soon)

            International sales welcome - PM me for pricing.

              Love your work TK.

              Someone told me once it takes 10,000 hours of doing/ practice to become an expert at something.... sounds like you are well ahead of time!

                My favorite TK thread is still the isuzu bellet head 'reco', however this one comes close.

                Cant wait to see what mini head is capable of when I eventually feed tony some money, and grab a number and wait in line

                  Ok, got some audible valve float at just under 8000rpm, so we're at 237hp @ 7250rpm for now.

                  Motor is off the dyno - gotta make it to a race meet this weekend, so time is up!

                  Down the track we'll shim the valve springs some more & do before & after runs on a chassis dyno to verify results, from there we can tweak the intake runner length to suit the engine a little better - I was expecting peak closer to 8000, so the trumpets are a bit short for the motor as it sits, can't be sure until valve springs are sorted tho.

                  I reckon she's got 250hp in her, will just take a little tweaking & coaxing.

                  I'll put up more numbers tomorrow, gotta bolt now.
