twice now I have run over 15psi for a week or so doing a few pulls a day in my bp powered MSP. both times the alternator ended up dying. both alternators were from 91 escort gts. im hoping they failed because they are 22+ years old. i put in a new rebuilt alternator from parts source a couple months ago that has not given me issue yet, but i am hesitant to turn it over 15psi until i move into a new house. at 15psi in 3rd gear cruising at 100kmph I can mash the gas and the tires spin. seems good enough for the winter. i havent had a garage to work in since i sold my house in october but in march i should either be leasing a house or will have found a new house to buy and will have a place to work on the car again, so I will turn it up over 15psi again as I will have somewhere better than the side of the road to put it back together if anything breaks apart at high boost. still trying to figure out whats up with alternators dying though. Even with the new alt and pretty much ever since ive swapped the bp the lights are always dim when i first start the car. doesnt matter if i have a brand new optima red top or even my buddy's new f150 battery, they are always dim at first. even the interior i would say are 10-25% dimmer. but once the motor is revved over ~2300rpm everything brightens up as normal. just sort of been living with it for years and it never really bothered me, but I am wondering if its somehow related to the alternator dying under high boost. the car always starts up right away so its not like im lacking power or cca or reserve power etc, and it happens even when i have all lights off except for drls too so its not like im putting some massive electrical load on the alternator from having lots of lights/fans on during/after cranking. even if i start the car and let it sit there for ten mins warming up, the lights are dim the whole time. the second the rpms go over 2300 its bright like normal and stays that way until the car is turned off. i have more grounding straps than anyone I know all over the engine/trans to different points on the frame so i know its not the grounding, but i am curious as to what else it could be. does anyone on feoa have any ideas? my buddy hooked up his multimeter and performed a battery / alt voltage test as described in the haynes manual and all seems fine.. Handling my ignition I have a megasquirt ECU, stock EGT ignitor, MSD blaster coil, stock distributor, bosch wires and colder copper plugs.
