We had great luck with JLT's 127mm Big Air CAI on Project Vapor Trail, so we suggested Carl give it a try on Jim's blown Laguna. Carl opted for the new plastic Big Air, but it was no less effective. In fact, it delivered even more impressive gains on this combo, adding over 60 hp. At this point there was more power to be had, but Carl had to stop pushing the combo as the fuel system was at its limit. With larger injectors and more pump or a pump booster, this combo could have kept cranking out huge power.
