Probably too much knock bruh.

Why should he not be smaller than a 3.6 if he has headers and a GenV? Would this be an acceptable pulley size on a GenIII?

Gen V's are more efficient at moving air so rule of thumb is the pulley size on a gen V should equal about .2 more than a gen 3. I had KR with my 04 when I tried a 3.4 on basically headers and a tune. Mostly went away when I pullied up to a 3.6

So help me to understand this... the GenV is more "efficient" (how so?) and this means you NEED to pulley up about .2 VS what you would run on a GenIII?

I'm just trying to figure out why.
