K03/K04 wastegate actuators from Forge

(1/4) > >>

Hurdy:
I've been looking at a thread over on Golfmkv's and subscribed to the teaser thread for the actuator development.

It looks rather tasty and for the K03 guys who have already modded to include a HPFP, intake and TBE it is going to hopefully rock your world.

The standard actuators on K03 are letting boost past at around 4psi which increases the N75 duty cycle, which basically reduces overall power and torque attainment across the rev range.

On a typical test they simply swapped the OEM wastegate for the Forge version and the car made these increases.

SAE Correction Factor:

Yes guys you read right, that is a gain of 42whp and 48lbft

Now the not so good news. The guy in question had a leak that was present before AND after the dyno's. This means that possibly if he hadn't had the leak he would have "only" seen an increase of around 15whp and 15lbft. Still amazing though.

Here's hoping that a K04 version gives similar results :jumping:
