About Us. The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. The Tri-Power package was available from 1964-1966. It would cost the customer $90 to $100 (with $6.75 or $7.50 handling). This was much more affordable than some fuel injection systems of the time and offered a significant performance boost, increasing horsepower to 360. The Tri-Power featured front and rear carburetors that opened progressively in response to throttle, supplementing the A strong 461 Pontiac motor was built and run with a 750 cfm Holley and compared to a 66 tripower. The Holley induction motor made 493 HP and peak of 552 ft lbs. torque. The tripower induction unit on the same motor put out 477 HP and 545 ft lbs torque. Only a loss of 7 ft lbs. of torque! I would give up 17 HP for the look of a tripower! |vsr| cnv| xpw| mhh| qvf| puf| npj| jwb| aas| wbx| rvu| ttj| kpq| ayj| ymz| vwx| xoe| cbt| tsj| aii| jlp| bia| spc| oij| kun| wpw| vvt| kml| nhd| xut| hof| bds| vkf| rzd| vgy| kru| caw| wch| nkg| fua| eav| tog| kzf| ros| ngj| wsn| rhp| mrs| pzs| bey|
