Hmmm....

I was looking at that earlier today -- seems like a cool idea and gives more flexibility where they can locate the turbos. Wonder if the cool air hitting 900+*F impellers when the tank kicks in might cause stress fractures overtime? Likely all very well-tested...

I hear they're having trouble with the emissions software. Perhaps VW could help.

This thread blows.

Considering the time it would take to develop this technology (testing etc before getting to this point) wouldn't they have still likely been part of Ford when this was on the drawing board?

If so, wonder if Ford at least co-owns IP on this? And... could it be used with Eco-Boost to get further gains in MPG as well as HP?

I couldn't find anything on Ford but could be. Seems like a rather elegant approach ...pump up a 2-liter can with an electric compressor and discharge into the impeller inlet on tip-in via a valve for instant spool-up.

In a way this could also 'cheat' emissions a bit in a way similar to '1968' air-injection pumped into the exhaust header to 'reburn' for smog control when what was really happening was diluting the pollution stream -lol Since tip-in just happens to also be one of the times when fuel-air ratio is necessarily 'rich' there could be some '1968' mischief in this too :shades:

As far as efficiency, I'm not sure it will be more efficient since the energy to spool-up the turbo had to come from the electric motor/pump and that seems to have to be a tad less efficient (electric motors are about 98% but pump/compressors are far less so both combined are less still) than direct exhaust pressure. But it's only for a very brief period so it may not matter. But quicker boost will get you down the road quicker.

Seems like it's not coming to America -- only on S90 flagship hybrid, it would seem. Maybe the '1968 mischief' I'm imagining is preventing from coming here -- or maybe I'm imagining to much :weg: lol

I think you imagine too much.

...how did I know? :giggle:
