Thread: Any guesses on what I will dyno with S2 Intercooler?

I also agree with taking further advantage of the full I/C by installing a CAMSHAFT. But at the end of the day, a full I/C, PCM tune, TB ported a lil, headers or at least 3" DP w/u-bend delete, 180*stat, CAI, 1-2 heat range colder plugs, with that 3.0" pulley, I think you'll be pulling much better than u did with the previous setup.....

So many variables. I would start with your largest pulley and keep adding timing until you get to 20* then pulley down. A smaller pulley means nothing if you are running 10* of timing.
