Was that Shaun mapping session on a damp day on the road near Peterborough....or am I remembering someone else?
If it was you on that day, then I seem to remember that you were told to floor it in third on a damp road, and needed a change of strides and a stiff, errr, coffee when you came back to the workshop?
What I am saying is that perhaps the on road mapping wasn't the best option for your wonderful engine? Yes, the best if an RR wasn't available, but perhaps not the best option possible? What do the experienced collective think?
Mine is a pale shadow beside yours, but mine was mapped on a RR, and then road tested after to make sure nothing had been missed. My BHP is 300, well below yours, but my torque is 330, and that's makes the car really driveable.

The question remains.... why does my engine appear to be the only one on this thread that has a torque figure lower than its bhp figure... and by quite a margin looking at other dyno's 
You're not the only one, my max BHP # is higher than my torque # as well.Mine was also mapped on the road by Shaun, flooring it at 30mph in 4th and holding it flat to the floor until just shy of the Rev Limiter is shall we say "somewhat interesting" on the M5
The normally aspirated no NoS Rover V8 BHP per litre challenge has moved on.
Carsy: 62.13 HP per litre.
ChimpOnGas: 62.45 HP per litre (LPG with standard heads)
Phazed: 69.96hp per litre
db484bhpv8: 71.69hp per litre
Chilli: 72.02hp per litre
v8bloke: 85.86hp per litre (TA heads)
I know there are loads missing but v8bloke's result kind of makes that irrelevant, those TA heads are expensive but totally game changing.

Agree regarding Shaun, will be speaking to Rob (hopefully), yep very noisy through the thin CF, sometimes I think there's a bag of nails loose in there 
Not sure when I'll be in sunny Surrey... I'll drop you a text/mail/call when I know... Presumably by back to back you mean RR? or compare noisy plenums
No your not getting me Not sure when I'll be in sunny Surrey... I'll drop you a text/mail/call when I know... Presumably by back to back you mean RR? or compare noisy plenums
concerning timing the cam most of us just fit the cam at the manafacturers recomended settings it dont mean that thats the optimum for a given engine spec safe but not optimum 
put it this way the Rover is to hard to swing the cam timing even if you wanted its to much of a palaver stripping down the front end of the motor

Spot on Anthony, we got the sideways thing going but Shaun didn't bat an eyelid, too busy focussing on his laptop.... we were a bit sideways at about 80mph and a couple of metres off the Armco.. obviously as a driving God, as all us TVR chaps are, it was not an issue..........

TBH I was cacking it

Engine spec ?
I'm happy with it Engine spec ?
It's a V8 Developments 5ltr with the 96mm Pistons and 4.6 offset ground crank, cross bolted with H beam rods, forged Pistons, top hat liners and a Stealth cam.
Ported intake, with heads fettled by Knight Engineering with 3 dimensional valve seats.
ACT 45mm carbon trumpets and smooth bore intake pipes.
71mm plenum and 20am airflow meter.
Vectra injectors and a 3bar fuel regulator.
Full decat with Clive's Y Piece and ACT cherry bomb exhaust.
Then chipped and mapped by Joolz
