gauge reading around 12 lbs..based on upper and lower pulley size i should be 10% over driven a lot going on when i have my foot in her , though when glancing at it looked around 12 . wish they made a blower gauge with highest boost recall

Do you know how much boost is being produced and what is your fuel pressure reference. Are you using any WMI and what is the octane requirement?

At what rpm is max boost produced and what is your fuel pressure reference. Are you using any WMI and what is the octane requirement?

Good Vibrations (whittier ca.)has a piece that will hold max boost until you reset it. You know like some tire pressure gauges. Hell you could even use a tire pressure gauge if you wanted too! Anyways,GV good people. Lots of blower stuff. Check em out.

COOL THANKS

STATIC COMPRESSION IS 8.5 WHEN 0N THE STREET I WOULD RUN 93 UNLEADED AND MAYBE SOME 1O0 NO-LEAD AV GAS, MSD BOOST TIMING CONTROL , IT RETARDS THE TIMING FROM 1 TO 3 DEGREE'S FOR EVERY POUND OF BOOST YOU MAKE. SO IF I BEHAVE MY SELF NO PROBLEM. AT ONE TO 5 POUND OF BOOST YOU MITE AS WELL CALL IT 10:01,SLAM IT TO THE FLOOR AND YOUR MAKING 12-14 POUND ITS EQUAL TO 12-13:1 IN LAYMEN TERMS . AT THE TRACK RUN VP C-16 BLENDED FOR NITROUS /BLOWER MOTORS .HIGH PRESSURE FUEL .BG 210 PUMP -10 LINE OUT OF THE CELL TO THE FILTER AND PUMP THEN -8 UP TO THE REGULATOR(7 -9 LBS) AND FUEL LOG. WANTED TO RUN A BYPASS BUT NEVER GOT AROUND TO IT, CAR RAN FINE WITH OUT IT.AT WHAT RPM ? HARD TO SAY(WISH I HAD A RACE PAC SET UP. WHEN YOU SLAM IT 1.30 60 FT TIME WHEELS OF THE GROUND ABOUT 5 " SHE SETTLES DOWN SHIFT LIGHTS ON AT 6,200 I WOULD GLANCE AT THE GAUGE AFTER PUTTING HER IN THIRD GEAR . THERE'S ALSO A THING CALLED HEAT PRESSURE THAT'S PRODUCED IN ROOT STYLE BLOWERS AT CAN GIVE YOU FALSE READINGS

Sorry about all those duplicate posts - thought the web site was not responding as it hung up my tablet - guess it was. Tried to delete the post but could not find a way. Must need a little more experience with this site.
