what are some fairly inexpensive easy power mods? i was thinking about ghetto rigging up some cold air in addition to the cowl hood. last night i was riding in a car and started screwing aroung with 36" of exhaust pipe and a 90* elbow. . . it threw tons of air in my face when i stuck it out the window. i was thinking about running two of those under the truck to up near the air filter to see if i got any gains. and then capping it when i went mudding. oh- if i got some turbos of of some Saab 9000s would it be POSSIBLE to put them on my 350? my auto tech teacher said it would work and we could do it in class if i got them. what kind of power could i expect?
