Forge Actuator Springs

[Sigilobaphomet]

Manufacturer spring ratings:

No 8 Green - 5-10 PSI / 0.3-0.7 BAR
No 10 Yellow - 9-15 PSI / 0.6-1.0 BAR
No 12 Blue - 14-18 PSI / 1.0-1.2 BAR
No 14 Red - 17.5-20 PSI / 1.2-1.4 BAR

Actual ratings when fitted (using lower rating as a comparison as on a 2.5 so no boost control):

No 8 Green - 4.5 PSI / 0.3 BAR
No 10 Yellow - 7.5 PSI / 0.5 BAR
No 12 Blue - 12 PSI / 0.8 BAR

Not got to Red as fitted a manual bleed valve and got up to a 2 PSI increase to get to the 14 PSI I was aiming for

Basically, if fitting these to a 2.5 don't bother with the stock or green 'upgrade' springs usually supplied with the standards - you will need the blue springs just to get back to the standard 0.7 BAR set-up from the original actuators

Good info. Might be worth adding it to the wiki.

Might need to order some new springs

Soooo is there any point getting more boost if you don't have a remap ?.

I have the greens on an otherwise standard 3R. Pulls 1.1Bar peak and settles around 0.9 but that's obviously with ECU assistance.
