fuel pressure, TPS setting, and timing for supercharger

302man · 05-07-2001, 12:16 PM

30lbers should be big enough with out a FMU. Do you have a chip or anything else ? MSD Boost retard box or PMS ect. ? But, basicly, to run a supercharger you need a big fuel pump, big injectors or a FMU to compensate for small injectors. MAS air is to be calabrated for a supercharger.Fuel pressure 45lbs, TPS setting the same as usual. Sometimes a small hole in the TB blade will help if you have some surging. Timing, pump gas= about 18 degrees, race gas 24-30 , depends on how brave you are. I run mine straight race gas and 112 octain and 24 degrees. (full boost) but I do know others who run all around in timing, like a A trim with 10lbs and 30 degrees straight out , unchanged. E-mail me if you need more help.
