Time for a cheeky wee update then!
Literally just back from test driving the car after adjusting the LDA preload, wastegate arm, shimming the gov, adjusting the throttle travel and fine tuned the idle and max fuel.
Fark's sake. What a difference.
Still need to adjust the wastegate further, it's still smoking under boost at 22psi. Only went 1.5 turns in from "stock" as I wasn't sure on the history of the turbo. However it DOES boost at 20+ psi up to just over 5.5krpm, which is interesting in the wet with relatively new tyres, a fair bit of camber and rock hard suspension. Wheels light up in third at about 50mph
I always told myself I was doing this for looks and fuel economy. What i've found is that I don't give a crap about the front bumper any more and i'm addicted to boost.
These VE pumps are actually REALLY interesting when you start looking into them. Spent hours this weekend reading up on the VW sites and to some extent the Cummins ones too. I understand them a lot better now especially as i've dismantled the head of one. Thinking of picking up a spare Bosch and rebuilding it fully just for the lolz.
Oh and a word of warning to anyone doing the gov mod themselves. Make sure the cradle's seated in the leverset properly or you'll turn your nice progressive throttle into a switch
Am going to spin the wastegate another turn when I can be arsed. Bit wet outside just now...
