whats the psi difference between the pulleys?
i dont know if im asking that right, i am used to turbos.

 

What would be great is dyno graphs for cars with no mods except each of the different pulley sizes.
Does anyone have a link to something like that (even if from a vendor)?

I have looked at the thread for dyno graphs, but it's hard to find 3 cars that are similar enough (except for pulley size) for comparison.

 

There was a thread a year or so ago that went into excruciating detail about size, #rotations and boost levels. If I find it I'll post the link.

 

You had me at "excruciating"
