wastegate adjustment.

[julek780]

Hi i have just got my new 3 inch full exhaust fitted and need to know if i need to adjust the wastegate, and if yes which way do i adjust the bar, in or out, ie away or towards turbo.

Hi mate, have you got a boost gauge? The fitting of the exhaust shouldn't effect boost that much anyway. Don't play with the actuator without a boost gauge as minor adjustments make a big difference.

Take the rod off the w/g arm, turn it clockwise half a turn. Refit, test drive and repeat as required.

Obviously on a stock map a bar of boost is about the safe max, if it's an 850 T5. Adjusting the wastegate rod for more boost will raise boost and bring it on more aggresively but I wouldn't adjust more that 2 turns from stock. It's a case of minor adjustments and running the car to full boost and monitoring gauge until boost is where you need it to be. There is a locknut on the actuator arm. Undo this and wind the wastegate fitting towards the turbo. This adds the preload to the spring. Personally I would prefer to adjust using an MBC and not touch the actuator arm.
