Hey you lot
I have returned !!!

Been otherwise pre-occupied what with the stresses of life but finally emabrking on sorting my mini finally


I have a AvonBar 8PSI actuator fitted; that only gives 5 PSI of boost !! I guess this is becasue of the preload that I have set ( i cant rememeber how much i set !! )

But to increase the boost , should i make the arm longer or shorter , do you know I am going cross eyed trying to work it out !

Duuuuuuuuuuuuuuurrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

I noticed the other day when I tightened up the actuator preload that the actual amount of boost produced increased from 7.5 psi to 10.5 psi so I had to crank the bleed valve in a bit to get it back down.
Seeing that uprated actuators are considered a better option than a standard metro actuator and a bleed valve combination(obviously running without the ecu), I wonder what would be the result if I removed the bleed valve and just increased the preload to get my 7.5 psi of boost.
