Alex will step in, but I remember him saying once during testing he found a gear drive cost about 5-10 hp over a chain. Is that right, Alex? ------------------

not to mention the harmonic transfer from the crank to the cam from the two being linked together with solid pieces..and the friction loss of that kind of setup.and the noise..no thank you true roller double timing sounds much better since i cant afford the belt drive.Bruce

Do you mean port matching?
Yes to all three questions.------------------

I hear from different sources that windage trays can be worth up to 20hp but Im sure it depends on what kind of sump you are running and how much oil you have in it. My buddy runs a rear drop sump and runs 4 qts oil in it, so he probably wouldnt benefit as much as I would with my street driven car with its front drop sump and 5 quarts of oil------------------
