Porting My CHINESE TURBO Wastegate To Fix Boost Creep!

Fix boost creep on a turbo charger by porting out the wastegate larger. My Chinese T28 Turbo came with a really small wastegate port. In this video I'll explain what happened and show what I did to make a larger port in the wastegate to get rid of the overboost conditions I was seeing.

Basically i was overboosting BAD. by 4500 RPMs with the stock internal wastegate I was hitting my 13 psi boost cut. This won't work for my low boost setup in my Turbo Exocet. So I wired the wastegate open and did a few pulls. My Megasquirt data logs showed I was hitting 6-8 lbs of boost with the wastegate open!

I ported out the wastegate and then with the wastegate wired open I was only hitting about 1 psi on a full redline pull. This along with some spring modifications in the stock wastegate actuator allows me to now hold a 9.5 PSI level of boost to the redline as I was hoping for. My stock chinese wastegate actuator was an 8psi spring. However with doing some test with my air compressor I was able to find out that it was only STARTING to open by 8psi and wouldn't fully open the wastegate until 25 psi.
My next video will show the spring modification to the chinese wastegate actuator.
