Right enough. The fuel is injected under pressure and the pressure determines the dump. It is not ideal on the VX with the blower, but it does work well enough. On heavy drops, I will catch a whiff of some fuel but never anything to worry about. I think a different pulley or higher vacuum blower, and you would get enough fuel dump to cause worry.

Ideally, you would want to consider a more economic system. Larger injectors, actuating fuel rails and pump, etc.

But, for a Sunday car for me, it's well enough now. Besides, there is nothing like going WOT on the merge lane on a highway and hearing that jet plane "whirring" sound from the blower and intake. The VX gets attention as is, but when it sounds like THAT.... oh yeah....
