Think about it Alan, if the injectors provide enough fuel with a
supercharger ramming all that extra air in, they'll have no problem
doing it with your modest mods. The biggest restriction on the exhaust
aside from the muffler is the pinched miniscule piping from the
manifolds to the convertor. Replace them with 2 1/4" aluminized pipe
(bent with care by a good shop) into a flowmaster Y pipe (summit
racing/jegs) and have the shop relocate the O2 sensor as necessary. From
the cat back I recommend the Gibson system. Similar mods on my truck
yielded nearly a 4/10ths gain. Here is my experience:
Stock w/invictas and Jacobs ignition 15.70
MP sbec 15.45
Exhaust mods 15.10
Pulleys/fipk/wider tires 14.90
180 thermostat 14.81@93.5mph
Hope this helps.
Andre
