OK, here is how much the extra 1# weight will affect the DMD. a formula was given about a year ago but I recall that for a 10 lb lighter flywheel on focus (which has same stock weight as ours) gave benifit equivalent to...
260 lb weight loss in first gear (at 15 lb/HP this is like +17 HP)
90 lb in second gear (+6 HP)
50 lb in third (+3 HP)
30 lb in forth (+2 HP..this is the gear you dyno at, so you see +2HP)....but they light flywheel SEEMS to give a lot more kick especially in first/second because..IT DOES!!
But that is a 10# drop with a big radius..so if the DMD was as large in radius as a flywheel loss would be 10%..
First gear...+26 lbs or -1.7HP
second.... -0.6HP
third..... -0.3HP
forth..... -0.2HP
However, with the DMD being less than 1/2 the radius, you can cut those numbers by probably 60-75%...
...Max loss with DMD in first gear...less than 1 HP...unmeasureably small in second and above!!!
NOW, think about how much extra work/power lost by rapidly bending a forged steel crank....if a DMD can reduce that by even 50%....I think you get my drift..anybody who has one can attest to the smoothness..."roughness" costs power (how much I do not know).
I post this just in case power loss is a concern. It is possible that people removing UDPs will feel minor loss (but perhaps not) but this is because they are underdriving accessories. If they use separtate UDPs for P/S, alt, they will not lose anything.
