    Hey guys so I just installed a stage 2 Hahn kit recently and a Aeromotive 1309 fpr instead of the crappy one that comes with the kit. Is it ok to run boost with just that (93 octane/8.5 compression btw)?

    You need to be able to see what is going on inside the motor, without the proper tools to manage your fuel boost etc no it is not safe.

    On something with such extensive modification that was never meant to run on forced induction I wouldn't recommend anything more than 4 psi without the ability to monitor wideband A/F and personally I wouldn't run any boost without the ability to monitor it as well as make adjustments to fuel timing etc.

    Get a wideband. Want to know your AF ratio? Welp, that's the only way you'll know, and will be the safest way to know whether or not you're about to blow up your motor.

    Have you done anything for fuel and tuning? 16g turbos run the stock 450 injectors on the turbo DSMs pretty hard at just 10 PSI.

    True but he's running it on an NA. Without proper tuning and monitoring software he has a good chance of doing some damage to his motor.
