I've heard all the debate about which pulley is better and it usually boils down to the fact that the 185 doesn't produce the hp b/c of the heated intake charge which pulls timing. What if you were to use water/meth injection to help tame those temps along with getting a custom tune based on always running the meth. Cool intake charge along with additional detonation prevention (high octane of meth) with the proper tune could do wonders. There is a turbo silverado in my local car club putting down 7XX+hp and he was saying water/meth gave him another 40hp. My thoughts are that there would be big gains, I don't know if it would be quite as big of a gain but I'll let someone else with more experience chime in.
