Excellent comments and a great Mexico story thrown in for good measure from Sewin, loved it

With this in mind, and before we play the peak numbers game, here's what really matters.....



Over 6,500rpm where Monty previously fell over on the Newman Phase 2 cams, on the new A.L Development ported big valve head and Newman Phase 3 cams, he's now delivering 40 ft/lbs more torque and 50 more horsepower as his Duratec spins out to 7,900rpm.

No wonder Monty felt way stronger at Castle Combe

We also recorded big torque and horsepower gains lower down too, in the real world this is where we spend most of our time on the road.



And finally, connecting the bottom end power with the mid range grunt, and then all the way out to the top end.... is this wonderfully flat torque curve!



This is what makes a car fast

Interestingly, Monty is now making as much horsepower at 3,000rpm as a standard Duratec Plus 4 makes at 5,500rpm, and the same toque as a standard Plus 4 delivers at 4,500rpm but 500rpm lower down, after this of course its just more, more more!

With this understood, what should no longer surprise anyone is Monty is actually more flexible to drive than a standard Plus 4 when I'm just tootling about, this despite all the tuning work that back in the day would typically leave you with a highly strung animal, as illistrated so well in Sewin's excellent Mexico tale

I feel the above results and the way I've presented them, is the best way to demonstrate to you all why I was never particully interested in Monty's peak horsepower number
