MAXSPL_153 Posted May 1, 2010 Report Share Posted May 1, 2010 just bought a 1997 dodge ram 1500 pick up yesterday . it has a 318ci and a full intercooled P-1SC procharger on it . truck runs good , but "sometimes" it acts like its loading up or (flooding) and has NO power , but if i punch it it wakes up and puts me back in the seat . any ideas on that ? and heres a weird one . every video on you tube i seen with the SAME procharger , its whining like a biotch , but mine you can BARELY hear . especially at idle . the only real sound indication its supercharged is when i rev it and get off of it you can hear that " flutter " sound as the access boost is evacuating the system . anyone know why i have like the only procharger that doesnt have that sweet whine sound?

bcpballer64 Posted May 1, 2010 Report Share Posted May 1, 2010 lack of oil? something blocking airflow?

I can't answer your question about no power but the whining sound comes from air getting trapped between the belt and pulley. there are plenty of prochargers that don't make a sound. I've seen people drill holes in the pulley so it's stealth, the belt could be a little loose, or any number of things Quote 2001 Tahoe.

MAXSPL_153 Posted May 1, 2010 Author Report Share Posted May 1, 2010 lack of oil? something blocking airflow? just went out and checked all vac lines / purge valve and fluids truck and the charger . everything is full and clean , no vac leaks , and as far as i can see no blockage in airflow. about the engine acting periodically think an o2 sensor could be causing that ?

MAXSPL_153 Posted May 1, 2010 Author Report Share Posted May 1, 2010 ill have to look into that , it does have a spring loaded tensioner though so i dont know how "tight" i can make it . wider belt perhaps? Quote Link to comment Share on other sites More sharing options...

smgs92 Posted May 1, 2010 Report Share Posted May 1, 2010 depends where you live if your gonna straight pipe it if you're in cali or someplace that checks emissions i wouldnt straightpipe and you said everything was hooked up correct? because that could be another reason for no power if something is blocking it when you rev up it spins it giving the power and if its blocked until you rev it it wont have enough suction so there would be your low power. atleast thats how my understanding of how a super charger works Quote Link to comment Share on other sites More sharing options...
