MRZ pulley review
And why is it bad to test directly at the battery?
reving quicker is the Primary gain you get.
you will NOT get much if any hp gain from a pulley..i think JN2's Dyno charts prove that point.....a 0.7hp gain from stock?..and i called this before it was even dynoed.
now using the pulley in conjunction with a light flywheel,lighter rims,lighter crank, etc.
then it starts adding up and real gains are seen...but taking 3lbs off the crank pulley isnt gonna make much difference alone.

Revving quicker=more horspeower, btw.

his STOCK pulley ran him 127hp ..the oem sized lightweight got 124 and the UD pulley got 128....
and it very well could have been..looks like it did give alittle more thru the range than the others as well, which can be expected.....btw what rpm are you shifting at on on the track?
Not trying to start an argument....have you considered shifting at 5500-6000 RPM? Your dyno charts show that the engine is beginning to drop HP and torque by 5300 RPM. If you run on a track I'd bet money that you will actually reduce your ET by shifting at 5500 RPM rather then 6500 RPM.

PE doest kick till about 4k-ish, most likely the PE delay ur feeling, or not feeling, w/e, but low end is all these damn cars have, anything after 5 starts dying on the 2.2
how to has been submitted, unno when the mods will approve of it, since i posted it a whle ago and it hasnt been approved to add more info to it,i made another including pics, vids of idle inside and outside the car,along with turning the a/c on
i got my fastest quarter mile time shifting at 6 grand when i was stock i havent tried it yet with my current mods but after i installed the 2.4 manifold and dynoed , my dyno sheets were showing a making power all the way thru the power band it doesnt fall off like it did when i dynoed stock
where it says "stock" is that stock sized lightweight pulley or OEM pulley? I can't read whatever the hell you wrote in the 2nd dyno
and would you guys please stop arguing about this. you're nitpicking over wording, you're all saying the same damn thing.
