Excuse me, the "theory" i explained is based PURELY on math and physics.
FACT: for every pound of rotating weight lost on the crankshaft, you will gain roughly 2.7 hp.
FACT: Leverage exists, to deny this shows a lack of knowledge of physics. A larger crank pulley requires less effort for the engine to turn the accessories.(ever heard of drag racers taking off their belts for a race.... its because the accessories take a large amount of power to turn, the pulleys use the same idea except they allow you to stay a daily driver)(also... think about turning a rusty bolt, would you rather have a 3 inch wrench or a breaker bar?)

I did not claim that whoever(acura owners included) puts on pulleys will be satisfied, as far as i know the VTECS pulley may be as light as it can get or there may be some other factor which limits how much under drive the VTEC's accessories can handle.
I stated the FACTs that the guy needed, and also the warning that he needed about possible side affects of underdriving the accesories.

Shivers may be completely right(i cant prove that he isnt...and I actually could care less if hes right or wrong), What i am saying is that as far as FACTS go, my facts can be proven with any old hand calculator..... his depend on the honor system and his own memory.

Perhaps you should look at a dictionary to find out what the difference is between FACT and THEORY

PS: Nothing against shivers/ but the premise of the "FACT" statement is that both preludes were Exactly the same except for the pulley, there are no cars exactly the same. They could have pulled of the assembly line with anywhere from 0-8 difference in horsepower, hell one of them could have a engine problem that is unnoticed..... for his FACT to be an actual FACT we need to see actual dyno results on, before and after the pulley swap.
