Hi ALL, the most perfect Turbo Boost gauge I owed was originally fitted to a B-24 Bomber, WW-II.
I painted one of the TWO pointers, one on top of the other, Red and the other Blue.
The Red pointer was used to measure EMAP and the Blue to measure MAP.

I’ve heard a couple of the ‘big names’ mention using map:emap as a ve table axis instead of the traditional map:atmosphere

So, instead of regarding bosst as Absolute pressure, we are measuring Intake manifold Boost MINUS Exhaust back pressure, essentially focusing on differential manifold pressure?

No it’s not minus it’s a ratio

Hi ALL, I hoped that this thread would into information about D/P.
When the Turbo engine is in "crossover" it will make great power with little chance of engine damage.
What is YOUR record amount?
