Stu @ M Developments,
The -31 is the part number of the SPRING and they lift around 8psi.
You want a -34 if you want a lift rate of 14 psi.
MGTurbo,
Have now purchased said -31 and look forward to the results..
General opinion of the -34 is that its too aggressive coming onto boost.
The gearbox is the weak point on my car and anything i can do to smooth out the power delivery is going to help long term. A softer actuator which the -31 appears to be, will give me steady boost (i currently have dropping off problems except in 5th where i get boost creep
)
To be honest my current actuator is 15 years old and well past it. I just wanted something thats going to do what i want with some added flexability, say, if i want to run 10psi and increase the boost to 15psi with a Dawes type device.
