hi to all has anybody increasted the pressure in an oil pump on an m20, if so by how many mm do load up the releaf valve by and wot pressure would it then be running at???thanks...

im not entirly sure on this, but with basic fluid dynamics taken into account i think you should,

leave the valve as it is and get a higher flow pump to incrtease pressure + maintain standard flow.

open the valve up with the standard pump to maintain flow and reduce pressure

not entirely sure though, why do you want to increase pressure? it may blow seals/head gasket

In a word, DONT.
The oil pump uses a VERY FINE (read easily broken) drive.
This item is a hex shaft only aprox 5mm thick and is in the direct part of the drive to your pump.
Wanna see what a broken one can do, NO YOU DONT !

and increasing pressure means you are sapping more power from your engine
