My guess is many factors contribute to it. I always was under the impression 12-14psi was max. But, that was because some guys were going SI trim on the Vortech, upgrading the turbine, upgraded bearings to overspin. That was bringing on the torque hard early in the power band. Torque is the breaking factor for rods/spun bearings.
I don't think i actually ever heard of anyone actually going through a headgasket with the v1/v2 kits even at 16psi.
So, how much boost can we safely go before headgasket problems.
