actually if you run a t3 or t4 style twin scroll manifold and turbo the lag isn't gonna be that bad... do some research on the t4 twin scroll setups... full spools on these huge twin scroll turbos are seen at 4500rpm and that is insane!! especially if your running on 2.2 or 2.3 strokers!! im currently doing a twin scroll setup with a 2.3 stroker block...so hopefully ill get the dyno sheet posted up soon
