Wow...cool, thanks!
I figured it had to be something like that. I can also see where the loss of backpressure in the exhaust could give you slightly better fuel efficiency.
Neat trick!
just an update on the turbo selection ,I have now had the k24 back on for a while now. The reason for the switch was due to a suspicon that the garrett was consuming oil.I now know that it was not an issue, however now that I have the k24 back on I can really better compare the two turbos. So basically for the little gain I recieved on lower end rpm with the garrett,I can feel how much better the k24 puts out at higher rpm. So once and for all in my opinion only I'am sticking with the k24. :lol:
Hey WishIHadaRabit, I take it that you disconnected the turbo because of restriction in the exhaust turbine housing? Is it more really more economical on the highway with no turbo?? Also what turbo is your 1.9 running?
About the pin situation, I guess it depends on your 1.9 pump. It has happened to some people that the 1.6 pin was too narrow and fitted loosley. Guess there is some pump variations on these engines. Im going to grind my 1.9 pin myself.
Hi Anton
yes it was more fuel efficient with no boost (3-4 liters per 460km), but my project took another turn and I have installed a Garrett GT22 + 1.8t Passat intercooler and even better fuel economy (5 liters per 460km)
I have pictures but don’t know how to post them.
The boost pin from the 1.9 is 1mm bigger then the 1.6 one.
Machine shop?
Can you do me a favor next time you pull out your boost pin, measure its diameter (wondering which pin is odd).
