[QUOTE="rotor_powerd, post: 15547888, member: 76391"] Boost pressure is nothing more than a measure of intake restriction to the amount of air you are trying to force through it. Saying "You can't use pump gas at XX PSI" is total nonsense. There are so many more factors than boost pressure that determine how safe pump gas is for your specific car. AFR, timing, IAT's, plug choice, powerband/cylinder pressure... all of that is much more important. A motor that brings torque in early and hard sees sky high cylinder pressures and will detonate on pump gas much easier than something that makes a lot of peak power given everything else equal.
