upgrade question. pretty important and urgent.
ok so im gtting a gm stage 2 kit but with a 2.9" pulley.. i have been told that if u run a 2.9" pulley you cant rev past 6600 or u can/will blow ur motor..ive seen many people running 2.9" pulleys and lower and seen race vids of them but i just want to know if thats true.. and if it is, is there something i can do to make that not happen? im getting a stage 2 and a trifecta tune. any help would be greatly appreciated! thanks..
EDIT: im getting it put on most likely wedesday.. which is tomorrow.. im also going to port the supercharger while its off.. im trying to be as safe as i can.. but once i heard that it got me kinda scared =/.. even though i still have 100k mile power train warrenty or 5 years.. if i blow my car up i guess im kinda covered...but just want to know what u guys think.. if its safe or not..
