Yes Tony - a 911 is a flat 6, I'm not sure on the CC's - all the gubbins we have, the injectors are rated in lb's. A quick google shows 80lb injectors at 840cc/min.
New pump going in on Friday, when I start to think about how much the pump has to do, at 192 you're travelling at over 3 miles per min, under 20 seconds = 1 mile, at roughly <5 mpg (on most track days we get around 6-8 mpg) the pump is probably flat out so that's the best bet at the mo and the pump is probably cheaper than trying to swap things around and the pump is a recognised weak point.
50 miles is about the max we get out of a tank on a track day - it's got a silly tank where it straddles the front drive shafts (they have been removed) - so the float don't work below 1/4 - and it's a small tank anyway, 14 gallons brimmed.
TBH I didn't check the fuel line pressure, I will on the next run in July.
You really can't check this on the road, even in Germany you'd need some clear space, the track day map is for mid range grunt and we've never had an issue, apart from the thirst, a new set of rear tyres per track day is the norm (Michelin 295/30's) as are brake discs and pads (not every track day, but if you have a couple of days at Spa you'd best book tyres, discs and pads) - the discs are bigger than my dollys wheels, and it's a lardy old girl).
Off boost she returns 30mpg - which is great for a long distance trip, and very comfy, hoon it and you're back to single figures.
Fastest lady again
