Ok chaps, so the reason I'm still only at 88% load (MaP), and despite being at 7,500rpm!!!!



Is because...... I'm only at 82% throttle opening as circled in green above, yes that's right, at 7,500 rpm there's still a massive 18% more throttle opening to go

And because my new 440cc injectors are still only at 64% duty at this point, theres still masses of headspace to continue to keep supporting that aditional 18% of air with fuel... and all the way to 8,000 rpm !!!!!



This demonstrates just how well a high port Duratec cylinder head shifts air, and how well the Fusion Fabrications inlet manifold and Supersports replica exhaust manifold are supporting that amazing cylinder head.

An internal combustion engine is just an air pump, and this proves with the right parts the Duratec 2.0HE is a very efficient air pump indeed
