Supercharger and pulley

[Fastest H-Town Realtor]

A-Why not ask the folks who make the blower the answer to the questions posed about pully size/boost with a stock blower. They would know best

2-"Boost" is an artificial measure of back pressure within an intake tract. The same 2 vehicles will exhibit different boost readings according to tolerance and manufacturing differences.What you measure with boost is the resistance of the air charge going thru the intake tract. Hog out(port) the intake tract and the boost read will go down.

I would buy 2 or 3 pullies then test the results according to the boost pressure guage. I would also be careful of overboost that could/will damage stock internal components. According to what I have seen/read/heard, anything over 500 HP becomes a dangerous trek.
