Stan­dard Cor­rected Power

Hot Rod - - The Easy Way & The Hard Way -

Our test­ing be­gan with what is ar­guably the best fac­tory in­take ever of­fered on an LS. Many af­ter­mar­ket man­u­fac­tur­ers have dis­cov­ered that the stock LS3 in­take is tough to beat. Sure, you can add power higher or lower in the rev range, but there will al­most al­ways be some sort of trade-off com­pared to the stock in­take. Equipped with the fac­tory LS3 in­take and FAST 92mm throt­tle-body, the cammed 6.2L crate mo­tor pro­duced peak num­bers of 580 hp and 527 lb-ft of torque. Nat­u­rally, all test­ing was run with the same air/fuel and tim­ing val­ues that max­i­mized power pro­duc­tion for each man­i­fold. This curve was to serve as the base­line for the re­main­der of the LS3 in­takes.
