All combos are assumed to be utilizing the best "stock" setup which includes 35lb injectors, large vam, 87-88 ECU, stock or ranger roller cam (unless stated otherwise), and most importantly, a good tune.
Remember these are estimated "maxed out" power quotes. It does not mean you'll make this much power automatically with this combo. It simply means when everything is perfect, dialed in, and maxed out, it should make around the power quoted.
-Stock engine, stock intercooler, no significant mods, 15-20psi will produce roughly 170-215rwhp.
-Above setup plus cone filter, 3" exhaust, 15-20psi will produce roughly 200-235rwhp.
-Above setup plus front mount intercooler, more boost, elevated fuel pressure, 255 lph fuel pump, ~22-23 psi will produce roughly 250-275rwhp.
-Above setup plus ported or gutted intakes, mildly ported head, ~22-23 psi will produce roughly 265-300rwhp.
-Above setup plus professionally ported head flowing 215+cfm on the intake, extremely high fuel pressure, ~22-23 psi will produce roughly 275-315rwhp with very high base fuel pressure (or run larger injectors, turbo, and a tuneable ECU like our PiMP and it could be 300-345rwhp).
Below requires upgraded injectors, piggyback ECU tuner or PiMP ECU, and conversion to speed density to ditch the VAM along with race fuel, E85, or methanol injection.
-Stock engine, turbo header, professionally ported head flowing 215+cfm, cone filter, 3" exhaust, 255 lph fuel pump, ported/gutted intake, large aftermarket cam, large turbo producting ~25-30 psi will produce roughly 350-450rwhp (stock rods won't last long at over 400rwhp unless the tune is perfect so plan accordingly).
Below requires many unmentioned items plus a standalone EFI system such as our PiMP ECU.
-Above mods plus Upgraded Rods/Pistons, 225+cfm iron head or Esslinger Aluminum D port head, ~30 psi will produce roughly 400-500rwhp.
-Above mods plus Esslinger SVO head, Stage III or larger Bo-Port cam, ~25-30 psi will produce roughly 450-600rwhp.
-Above mods plus Esslinger ARCA or XT head, Stage IV or larger Bo-Port cam, 2.65L+ stroker engine, ~30-35 psi will produce roughly 700-1100rwhp.
I found this on the Stinger site. Nice little how to. Actually it's kinda helpful for my build too.
