Hey Rod, how do you do that? I wans't aware there was a modular 3.8 pulley out there. Don't tell me you're pulling and pressing them on and off each time?
I know INTENSE has a MPS, and I belive ZZP has one too. Maybe even Pulley Boys. Then South Florida Pulley has a Dial-Ur-Boost system.

i have a dial ur boost system with a 3.8" and a 3.3" pulley
i can change my pulley in 8 to 10 min.
if i take my belt off my mpg goes down with NO POWER.
without a belt my ford ranger is quicker(sic).

Ok, so dial ur boost makes a 3.8 pulley for their system. That'* cool. I don't think anybody else does. Too bad it won't fit on my ZZP MPS.

also Pulley Boys Qwikchange system make a 3.8" pulley and a 4.0",4.2".
if i did not already have a Dial ur Boost i would get a Pulley Boys system
they have the most pulleys to choose from (size wise).

Why change pullies for milage? If you stay out of boost you should get the same milage.

You are right, if you stay out of the boost. But every freeway overcrossing, every stop light you take off from, you are in the boost. We live in the Sacramento Valley which is pretty flat except for freeway overpasses. When we take a four hundred mile road trip to a sprint car race we see a drop of approximately 3.5 miles a gallon. That is 97% freeway and 3% city. If we drive daily to work we lose approimately 5.5 miles per gallon. We have over 80,000 miles on our modular pulley system, and it didn't matter when premiumn was $1.50 but at $2.50 plus a gallon it costs $45.00 or more to fill up my tank. Call me a cheapskate, but I change the pulley when we go to the drag strip or my wife wants to go out and have fun. (IT IS MY WIFE'* CAR)
