Ok chaps, lets study the facts shall we, the ECU logs do not lie wink


Here I'm launching off the line, Monty hits 6,637rpm as I snatch second gear.

There's plenty of fuel going in as the Duratec takes a big drink running my target 12.5:1 AFR at full spank, those big old Green Giant injectors I went with were definitely the right choice.

To burn that nice rich mixture of 99Ron as effectively as possible and build maximum cylinder pressures at 17 degrees after top dead centre, I'm lighting the fire 27.5 degrees before top dead centre at 6,532 rpm, this is just on the limit of knock so my timing is perfect too.

But Im changing up 600 rpm too early, holding to 7,250 rpm is the answer boys, taking it to 7,250 rpm I should hit 28 degrees of ignition angle at the same nice rich 12.5:1 AFR target to deliver my ultimate peak horsepower potential, Monty the Morgan definitely has more to give thumbs


Throttle is 100% wide open as I go over the finish line at 6,443 rpm and my injectors are still only at 47% duty, those Bosch Green Giants are proving themselves once again, but I need the engine to build speed faster, this way I will reach peak power at 7,250 rpm just as the flag comes down.

Despite pinning it as early as I dare exiting the final bend, and being at wide open throttle as soon as I can, there's simply not enough straight before the finish line for the engine to get to 7,250 rpm. But here's the answer, this 3.2kg Titan steel flywheel is set to replace Monty's 12 kg millstone, it'll make the Duratec spin up like a motorcycle engine so l'll cross the line at 7,350 rpm just as I bounce off my rev limiter calibration.

So Monty's engine has more to give, and I've estimated losing the passenger, the luggage rack and the spare wheel will also save me 120kg. Removing the 120kg is easy, it's free performance and given it's a big percentage of Morgan's claimed weight of 927kg removing all that ballast is going to make a massive difference to my time, add in some practice and some training and I see no reason why I can't slice a number of seconds off my current best time.
