Hello
As you know, the VTT team has released the shotgun kits which simply over driving the HPFP pump , it works well and provide awesome direct injection performance.
but the kit can not run in the cars:E6X 5 series chassis, XI models or models with Active Steering. So for these cars ,people only has to choose Port injection or port meth injection as an aux fuel supply.
I am thinking and planning the next way :
please see the picture , the vacuum pump gear (the read arrow) drives the vacuum pump and fuel pump. If we recuded this gear to 2/3 size, we would get a 50% increase of pump speed. for support, we should reduce the length of the oil pump chain and modify the chain tensioner steel as the blue arrow.
My plan is increase the 50% speed, so the chain tensioner maybe need only a little change.
50% increase is good enough for people who run good pumps but lack of fuel when applying single turbo.
My question is :
Does this way sound workable ?
is there any difference in tuning?
All your ideas are welcome
thank you
