Yep got it. Thanks.
OK looking at the steering wheel left lock is applied at 6:34 and is kept left of nuetral until you slow down for the car ahead at 6:49, most of that time you are at full or high power.
Had you not been blocked you would have kept left lock for another 5 seconds or so before the next right.
300bhp NA is about 1.5 lt/min with an efficient setup (bsfc .5)
300bhp Sc is about 2.1 lt/min (bsfc .60)
The capacity of the OE unit at 1G (45 degree tilt of the fuel inside) is 240cc so you can expect about 9.5 and 6.8 seconds respectively for NA/SC
The capacity of the new units at 1G (45 degree tilt of the fuel inside) is 280cc so you can expect about 11.2 and 8.0 seconds respectively for NA/SC
The video would suggest a minimum of 16 seconds though you need to adjust for actual BHP +/- (not exactly 300bhp as above) and max throttle time as this will not be 100% probably closer to 80-90%
I have little doubt that the canister is full at the start of the left turn for two reasons, first, the preceding right is quite tight, even without the recharge system at 1G lateral the fuel would flow over the top of the pump unit (either) and fill it instantaniously. Secondly, based on the above calcs you would not get the times before stall you are seeing as they are very close to the expected times available for the fuel available.
Clearly no pump unit can solve this issue as it is nothing to do with the pump or the unit but simply lack of available fuel.
The only solution is a trapping of some sort.
For this particular corner you might find you can solve the problem by reversing the G for a couple of seconds.
As you come out of the first left and proceed uptake hill, at time 6:31 continue turning left off of the race line and move over to the left side of the track, then switch G and gently turn right (.3G) until you are back on the racing line. 5 seconds will fill the new units, with the OE it will take quite a bit longer as you have to un-stall the eductor first.
