Hi,
No matter what size it is, a lobe type blower does not heat air since there's no compression within. The heat comes after from the air pressure increase in the plenum chamber since it pumps against closed inlet valves 3/4 of the time. Obviously, some of the plenum heat will then transfer to the charger...
When I researched mine, I saw plenty of guys using big blowers and running them slow, then moaning about the pulses and the lack of space on a bike to fit a big plenum to smooth things out...
Solution then did appear obvious to me, run a smaller charger = more rpm = more pulses = more dampening = more equal share per cylinder...
These Ansin are good for 12,000 rpm constantly. The blurb says 16,000 rpm for short blasts is OK. and that's on fuel injected cars when the Ansin just pumps air and does not get cooled further by evaporating A/F mixture.
