CAI
Kooks LT 1 7/8 catless
Rotofab I/C Reservoir
ID850
New plugs and wires
Possibly 90mm throttle body
Dyno tune after mods
Any help with one way or the other would be great. Also, on the ligenfelter chart, it shows that you don't need an idler relocation for the 18% lower, then on the next line it shows you need one? Which is correct?
Thanks,
Travis

Hello Travis, I recommend the 18% with your mods.
When you move to a cam you will go with the 23% pulley.
Ideally you want to keep IAT to a minimum and not exceed the knock threshold of your octane.
Especially in a road coarse situation.
My 125 RWHP package is what I run on my ZL-1 on the road coarse, it uses the 18% pulley.
Ted.
