Hi all,
I have this idea of going for dual injection for my VW Golf MK6 1.4TSI Twincharger. The goal is to cool down the supercharger, and I hope I can get an input if my idea is ok.
Below is a diagram I made:
And here is the engine
As of right now I already use 1g/h nozzle right after the intercooler outlet. It works great and to cool down the air charge and enough to allow me to run safely on Revo stage 1 98ron map on 95ron fuel.
But I am wondering what if I inject pre-supercharger, and if I do it would it be ok?
I only plan to use a small size 1g/h nozzle, just enough to cool the air intake entering the supercharger. But at around 3000rpm, the supercharger is turned off, and the bypass valve re-route the air intake to the turbo.
I read for pre-turbo it is best to have the nozzle very close on center. Now since I am spraying before supercharger with small 1g/h nozzle, I think by the time the air intake reaches the turbo it should already be fully vaporized and it should be safe for the turbo.
What do you guys think?
Please assists~!
