On an FP Green make sure the centre of the WG arm (on the actuator) hole is 8-10mm away from the centre of the WG pin (on the turbo side) it needs to slip over. Any more and you will experience spikes, any less and you wont hold more than 21PSI.

You cant modify this easily once on the car so sort it before its installed.

Had to stop in the middle of a tune cause the same thing was not instaled properly as a DIY by a customer.

 

ok. thanks alot for the tip man. ill be sure to do that. ill be set for about 23-25psi. will that change the distance or not???

 

It's easy to change once it's on the car go with 3 turns to start.

 

dont u have it backwards?

 

It should be fine.

And yes WG tension can be adjusted on the car with the right tools. Without them you stand a good chance of mangeling the radiator when you try slip the tensioned actuator arm over the pin. Tight space & some spring pressure you can make it tricky, but hey some get it right with home tools.

 

No.
If your WG actuator arm extends past your WG flapper lever pin which it needs to slip over, then there will be no spring pressure to hold the WG flapper closed, and therefore yout turbo cant generate any pressure.

It needs to be 8mm (1/3 of an inch) short of the WG flapper pin and then you need to pull the WG actuator lever out and slip it over the WG flapper pin, hence forcing the WG shut untill there is pressure in the WG actuator.

 

gotcha... ur original statement is very vague...

 

thanks for all the help guys but ive got bigger problems right now unfortunately. if interested i posted up in the engine/turbo/drivetrain area and the title is big problems.
