Aerodynamics are appalling on a 7, takes a lot of power just to push it along at 70mph.

12.5 AFR at WOT is a bit rich unless you're running forced induction and looking to cool things down with extra fuel.
Around 13.2 to 13.4 is where I thought max power was at?

If so it will tell you most of what you need to know.
You want to aim at 14.7 cruising and light acceleration. And 12.5AFR WOT. I assume you have mapped using alpha_n and not speed_density.
Upload your msq and I will have a look.

Fastest burning mixture is at 12.5 and is also where max power is 
Forced induction often run as low as 11 but thats extreme.

Cruising up from Detling show the other week I got near 35mpg at around 70-75 , but hooning brings that down to under 20
Thats a 2.5 V6 in a fairly heavy Fury .
The crossflow I used to run would do high 40's at motorway speeds - a full house , 165bhp screamer on Omex and TB's 
Its cuz I is blond , innit

It was a round trip of 250 miles to and from Stoneleigh. I managed to get that out of 1 tank of fuel in my R1 5vy powered VortX - 30mpg i was very
pleased with that. We was 2 up in the car too, so more weight

At Knockhill, it used 1 litre of fuel per lap of the track.

11:1 sound like you're getting close to washing the bores. Or maybe that's when you're hitting single figures
I'm sure they set up my 200SX (S14a ~370bhp) up at around low 13's

The reason is the wife won't let me thrash it when she's in, so most of time 65 to 70 mph.

single figures is bore washing territory. However low 13's is a bit risky on a turbo lump, 12.8 is as high as I'd ever like to see on my
XR2 turbo - based on advice from various tuners.
our 2.0 pinto on 40's did low 30mpg's on last years le mans trip.
The 2.3 duratec on ZX9R carbs did 37mpg going to the rolling road and back (about 120 mile round trip, cruising 50-80mph and some booting it).

Quite a informative thread. I noticed JollyGreenGiants post with a MPG of 25. Everyone always says that Rover V8 are big, slow, heavy and terrible
on fuel. At not much heavier than a Pinto, pushing 200 BHP coupled with 25mpg it seems like a good option!
Makes me happy considering a V8's going in mine!
