Tuned really well.. you can run 10psi just fine.. maybe even more but i wouldnt push much past that.

hypers can take boost.. just not bad boost.. so make sure everything is tuned very well cuz hypers dont put up with detonation very long.
geneos5546, Look at my singature I made a few trips to the track and some street miles. It has a self tune (no dyno time) and runs perfect. It has 11lb. most of the time when the belt not slipping. What paxton do you have? Do you have any belt slip?
