Pix below of the power curve and output figures below. The curve very closely resembles what TCM shows in the Sentra brochure. The 25k km mileage engine's bone stock cept for Heat Range 6 ND Iridium plugs and a K&N drop-in element replacement filter. Figures are all at the crank.
The torque curve and output figures
As you can see from the power and torque curves there's a very pronounced dip between 3500rpm to 4000rpm. Most people actually feel this deep as a surge of power thinking the engine's VTC is like VTEC. Wahahhahaha! This proves once again that butt dyno's are only good for feeling power/torque transitions rather than gains. I have a set of Hot Bits stainless steel headers and exhaust b-piping on order. This should hopefully get me some gains and
reduce the dip in the curve...
