3.5 vs. 3.4 vs. 3.25 vs.3.0 pulleys
Can anyone tell me the major differences between pulley sizes:
What other mods are required, hp gains, etc.
I have 3.5 and want to know what is the benefit of going down to a 3.25 with my current mod list? Are there trade offs to downsizing the pulley?

looks like 3.5 may be your limit till you do something like rockers, pems, fwi, etc. I run a 3.4 with rockers and fwi, only using a 3.2 for racing. If you don't get more air flow, you will get kr and defeat the purpose of a smaller pulley (to push more air)
