Re: 181-Pulley Fact, Fiction or Matter of Opinion?
Intake, Pulley, Tune, Cooling
This is the mod path we all seem to be going - and then asking the question in between mods - does it really work?
Mod #1 - Should be cooling the IAT's to the MAX before anything else (bigger HE, pump, separate coolant sources, heat wrap, etc..)
Mod #2 - Preparing the engine to flow more boost (Intake & perhaps headers?)
Mod #3 - Adding more boost (Pulley)
Mod # 4 - Tuning this combination up (ECU)
I didn't follow this route - I went 2,3,4,1
I truly feel that once you tame the IAT's - the performance gains from the other 3 mods (all which will increase the IAT's and will affect your timing) will not be lost on you......
The bigger you do each one, the bigger the performance gains you will see.....
But if you don't address the IAT first...
I feel an IAT gauge is more important then an A/F ratio gauge - unless you are going to tweak the ECU settings continually. You can actually do something about the IAT's.....if you have the right setup.
