Boost Q's
Whats the difference between boost from a turbo and from a S/C? If any, besides the time it is delivered..
Also, ive been holding up on the 3.0 pulley installation because im afraid of damaging the engine since everyone says to stay under 10 #'s. Right now im at 7-7.5 with the 3.40, do you guys think ill be fine or just stick to the 3.40?
4.8, mods: mp112, 4.10's, Lt's, custom 3" Y, truetrac, 3k stall, and tune

Boost psi is just a measurement of restriction. It doesn't matter what the source is.
Assuming a stock 4.8l, the compression is around 9.5:1 so you can easily run 10lbs with the right tune. What kind of psi do 4.8's with long tubes see with a 3.0"? Might be better to try a 3.20" and see where you land.

Do it if you or your tuner has an idea of what they're doing. I ran 12lbs on my old 5.3. Buddy has a procharged Silvy w/220k miles and 135k of them are w/ blower at 10-12 psi on pump gas.

you wont have a problem with the bottom end giving out, like most have said you'd be fine with the 3.0" pulley with the correct tuning. only thing is belt might slip a since the pulley is smaller and belt probably stretched some.
