Like the bearings are ceramic, the crank has better balance and the ports are timed better.
is the port timing advanced or retarded from a stock V-Spec ?
If the power is higher in the rpm band the timing is most likely higher than stock.
I doupt timing is actually different...the stock V-Spec is already maxxed out as far as timing......any more timing and she will lose power....I will time a speed very soon, my bet its stock V-Spec timing. As well according to the dyno the Speed only makes more power at 28K..after 28K the Speed falls off pretty badly from the stock V-Spec..its power is not shifter upwards at all............the motor just makes a tiny bit more peak...1.48 HP for the regular Spec..and 1.51 HP for the Speed on the dyno.......... top end HP belongs to the regular V-Spec and so does low end power, only at 1 tiny point int he powerband does the Speed surpass the V-Spec.................. All i know is a properly modded V-Spec will blow the doors off a Speed !
