AMERICAN MUSCLE-Hot Lap | 660HP 2008 Shelby GT500 Whipple 2.9L Supercharger Upgrade


PAOLI, Pa. (DECEMBER 26, 2018)


In this episode of AmericanMuscle’s (AM) Hot Lap YouTube series, AM host Justin Dugan gets the keys to a customer’s 2008 Shelby GT500 to swap out the stock Eaton M122 blower with a Whipple 2.9L Supercharger Upgrade Kit as well as some accompanying modifications. The 2008 GT500 was a marvel in its day but there has been a considerable amount of advancements in automotive technology since its release over a decade ago.

To bring this GT500 into the current decade, Justin adds some thoughtful supporting mods as well as an updated calibration from Lund Racing, to ensure fueling and intake air temperatures are in check. Before and after dyno pulls performed on AM’s climate-controlled, in-house dyno confirm horsepower and torque gains across the entire powerband.

Parts featured in this video include:

Whipple’s W175AX 2.9L Supercharger Upgrade Kit , VMP Dual Fan Triple Pass Heat Exchanger,

DeatschWerks 95 lb. Fuel Injectors, JLT Performance Super Big Air Cold Air Intake
