Re: intake manifold pressure

Do you mean the torque for the bolts if so
I believe it is 20ft lbs for aluminum or 25ft lbs for cast iron
Not a 100% sure

Re: intake manifold pressure

Help us to understand what you mean. Intakes run at a vacuun unless your engine is supercharged. Then there are several variables that determine what the intake pressure would be.
