AntiLag dont work like that mate.

Tons of nitrous or tons of revs (ie if the engine could rev to 10k or so) would get it spooling up even on a 1.2, but tis still pointless really, as youd never get it to a level where its doing better than a smaller more suitable turbo would on a diddy 1.2.

If we was talking 80s F1 style engines, fair enough, but even on them its a bit much

Tho if im reading the compressor map right, it can flow about 800bhp's worth of air at 0.5bar
