when the car is at idle the voltage gat is somewhere between 13.9 and 14.2 but when i jump on it the guage slowly drops down to about 12.9 and i start getting knock retard. My question is is this voltage drop normal. I do have a e-water pump and some n20 goodies if that helps.

anybody know if the voltage gaeg is saposed to dip under a load of anykind?

 

Well the only thing that might be causing that is the fact that you have the LTCC coil packs , i am no expert but i would think those would draw a little more power under load. also with the electric water pump too, so i'd say 12.9 is fine under load. **** mine is like 11 something at idle cause i have UD pullies and under load it goes up to like 13.5 to 14.

 

first off let me thanks for the reply. I noticed that you said under load your volts go up to 13,5 to 14 mine do the exact oposite they go down under load. do your's go up because of the underdrive pully's?
