How much boost

Post by osargeant »

What is the maximum boost that I can run on a MX3 1.6DOHC vehicle using only a Cartech RRFPR, 1.8 Miata Injectors and Walbro 255 fuel pump as fuel management along with slightly retarded ignition timing.

I am currently running 12psi on my car with a IHI VJ11 turbo with no problems and just wanted to get you guys thoughts and suggestions.

I acutually ran 15 pounds of boost on a T3 with 370cc injectors on my DOHC if that helps.

Thanks Jarid,

I just wanted an idea of how much boost guys were running on their stock engine setup. I will stick to the 11/12psi that I am currently running for now.
