Gents, it's been a while..
I have been very busy rebuilding a 23 year old car.
BMW drivetrain project is coming along nicely while the shell is stripped, rustproofed, corrected and repainted.
Also, I now have a larger exhaust turbine (and associated supporting cast members) on the big (LP) turbo.
I am planning on running 18 psi on this system.
Here's my question:
My @Reverant built MS2 Enhanced has a built in MPXH4250 MAP sensor. It is a 2.5 BAR sensor, good to 21 psi boost.
Do you think I will have enough headroom for proper overboost protection, etc with this MAP sensor?
Should I consider replacing it with a MPXH6400A which is good for 4 BAR?
