Odyssey is the brand of battery... anyone know what size would work best?? and it isn't a charging problem.... the car is far far from stock and tends to sit for long periods of time in between running it... the stock size 58 battery just does not have enough cca to run the two fuel pumps or the hi6 with a ps91 coil, here is a slight detail of the car.. 92 mustang lx dss 306, 185 afr heads, B-41 cam, edlbrock upper and lower, 60lb injectors, Pro-M 3" protube universal mass airflow, 70mm throttle body, ati procharger 14lbs of boost, huge intercooler, crane hi6, ps91 coil, tweecer rt, lm-1 wideband o2, shorty 1 5/8 headers, x pipe,fluidyne radiator, flow masters, 6pt. cage, subframe connectors, camber caster plates, 2 inch drop with progressive springs.. thats about all I can think of right now..
