the torque curve and the redline say so. at peak HP the Civic Si makes about 130lb-ft of torque @ 7800RPM. if we increase this by 40, now we plug in the formula. 7800RPMx170Lb-Ft/5252=260HP.

the only way around this is to change this is to change the redline, the torque curve, or both.

for the car to rev up to 8200 and only make 200HP, torque NEAR redline cant be much more than about 140lb-ft. you have to understand that HP comes from RPM AND TQ. you cant just up one and expect nothing else to change.
