Actuator Problem

[Turbjj]

Hi Folks,

In May i was at Henk's Place in the Netherlands to get the 21 set up with 76mm exhaust and new Turbo. I fitted a Forge Actuator with yellow spring on the Turbo.

On the old Turbo, i had an OE Actuator an was running 1,5 bar Boost (22Psi).

I didn't touch the Boost controller after the Turbo change, but the Turbo spooled up very slow and did not manage to pass 1,1 bar (16 Psi), so that we only reached about 223,6 HP/ 383,3 Nm on the front wheels.

At Home i fitted the OE Actuator on the new Turbo an set the Boost controller a little bit, the Turbo spooled up a little better an i managed to run 1,4 Bar (20 Psi) Peak an then dropping between 1,25 an 1,35Bar. The car was a lot quicker then before.

After this i bought the Tuning Kit for the Forge Actuator, fitted the red Spring, witch is the strongest, and changed the diaphragm (same as before, but a new one)

Now i'm stuck at 0,7 bar (10 Psi)

Does somebody have an idea?

Should i put back the OE Actuator or try the other Forge springs available (blue and green) (I have them)?

Have you changed the actuator rod length when playing?

I changed the rod to a new one, +- same length but i did no measure it out. I had to bend it a little bid to avoid the oil drain, but i have done this before on the OE to. I don't know how you name that thing in english that opens and closes in the turbo exhaust housing, but it should close fine.

Its not about the length ( tell that to the wife ) its about how far it is screwed onto the rod. The shorter the combined length of the actuator rod + eyelet rod = more boost. Longer = less.

Lol, it's not "all" about the length, but the longer it is the deeper you can screw in. I take the W/G out again an compare the length of the Forge and OE.

Thanx Andy!
