I think next time I will put in 'towing' tyre pressures to lower the rolling resistance, see if I can inch another point out of it. There were no traction issues off the line as Launch Control pre-primes the Haldex clutch.
Then after map couldn't run it in 4th anymore - too much power low down, was skipping the rollers and trying to climb off.
Had to run it in 5th, and by 5600rpm was producing 323BHP mapped. They swear there is more to be had, but at those 5th gear speeds on the rollers it was pushing luck with regards to tyres (acceleration on rollers generates a lot more strain/heat on tyres).
Looking at the curve from the print-out, it'd probably end around 330-335
Throttle response is massively better (being EPC throttle) and you can tell what they mean about the torque. It used to bring in the big surge of take-off power at ~ 2400rpm, whereas on the way home I was booting at at ~ 1700rpm and it was taking off at a similar pace.
Haven't really played much with the top-end as you can tell the map is bedding in again, it's a bit 'rough' in its delivery like the engine was new. By the time I got home it was smoothing out like the new engine did after a few hundred miles.
I'm taking my family to Yorkshire on Monday to collect a horse-lorry for my sister, so it'll get another good run out to bed in then
"Storm engineering have taken an R36 engine apart and noticed the cylinder head had bigger valves than the regular 3.6 V6 and managed 40BHP with a map. Normally n/a engines don't do much with maps so even here this proves the R36 engine in detuned and has plenty of potential. Wonder if anyone does any cams yet!"
