Questions- Performance Parts?

well im throwing in a under drive pulley ordered it today for 186 shipped from MRZ performance. adds horsepower and from what ive seen ( in many other forums(eco and gas saver forums)) it can give you an extra 2+ miles a gallon there for pays for its self

careful, under drive pulleys affect alternator out put.

i read about some ppl having problems with the lights dimming from the alternator not rotating as fast but a common fix i saw was they replace as many lights as they could with LEDs

the alternator still will have to work too hard and will kill your fuel economy and cause more parasitic loss of hp. every time your start the car you are essentially killing the battery. a dead/weak battery makes the alternator harder to turn because the rotor is energized with more amperage causing a stronger electromagnet. also this over working leads to premature failure.
