Manifold pressure 366 mbar

[hsustyle]

My 182 has a manifold pressure reading of around 366 mbar when hot.

Was asked to check this in relation to timing being out.

What does that reading indicate?
Car start, idles and runs perfect without misfiring or heating issues. Just dips in power past 5k a feels generally slow.

It means you have around 9psi of vacuum with the throttle closed and will go to around 1000 mbar with the throttle open, if the cam timing is out you will see a higher figure

So this is pretty normal reading for a warm engine?

Mine runs 400mbar with 438 cams, so I would say yours is acceptable if a standard motor

yea your numbers are about right for standard

Mine's a standard engine with very lumpy tick over - see thread below - and I appear to be reading around 500mB or so on idle. I'm resigning myself to the possibility that the timing may be off. Can you let me know what a reasonable figure for a road engine on idle should be ? Thanks.

Very interested in seeing how you get on Davy........mine is idling IDENTICALLY to yours.
I think mine is belt related (changed last year) but I am unable to fix this myself unlike you. Would be keen to see if your work remedies the idle as I was about to start buying injectors etc.
Keep us posted
