I do like the term "underlap" I hope you dont mind if I use that in future :-D
As you can see they are crying out for some attention. With regard to our figures they will be remaining firmly under our hat for the time being, market forces etc.
We will be more forthcoming with results though once they become finalised.
Please realise the results will be improved performance from zero to hero on the tachometer with NO holes in the power, and more grunt right through. These motors DO respond well and there is real performance gains just waiting to be unleashed with some correct attention, very satisfying of Mr Bloor to make them in that manner, and with the strength and reliability built in.
