Trying to decide on taking the dive with a 62mm pulley,if I do I will sell my code 3 pulley with a 100k miles on it ,I also have a stock pulley that will be for sale also,whichever pulley sells first will have a new bearing included PM me some offers I have a week to make my mind up so first real offers may get some good pulleys.

 

How many mm is the Code3 pulley?

code 3 pulleys are 64mm I may be slightly off but best bang for the buck I had this pulley for 5 years trouble 5 not counting the year the prior owner had the vechicle

 

highly advise that you ensure you are happy with the smaller pulley before selling off your c3 pulley. also highly advise a wideband AFR gauge on your car!

 

Would a bigger fuel pump negate the need for the AFR since the computer could supply the increased fuel needed for the higher boost?

 

nope, not with the amount of boost the 62mm produces

 

So the AFR would do what? Tell you to take your foot off the gas? What needs to be done prior or in conjunction with putting on the 62mm pulley? Since I have one I want to put on! Got your CAI and a MAXBORE TB will go on with the pulley.

 

the AFR would most likely be dangerously lean and could potentially cause catastrophic engine damage.

in my opinion, in order to run that pulley you would need... fuel pump, injectors, fuel pressure regulator, filter, AFR gauge and a tune to dial it all in, probably a reworked MAP sensor also.

that is just one of the reasons that we do not run/recommend that size pulley
