Stage 1 - $CALL FOR PRICE
The Whipple Stage 1 system is a computer recalibration that increases the maximum rpm level while maintaining a conservative timing curve for 87-octane gas. This calibration is designed to be conservative and reliable like stock, but a higher maximum rpm level for more prop selection. Stage 1 achieves only modest power increases such as 15 foot-pounds of torque and 10 horsepower.
Key features:
• 5450 RPM limit
• 87 octane safe
Stage 3 - $CALL FOR PRICE
While Stage 2 gets peak power from the stock engine, Stage 3 combines power and looks together for a very unique package. After extensive testing, Whipple found the CMI E-Tops to produce the best power curves for the 496 engines. To go along with the stainless headers, Stage 3 incorporates a custom stainless engine cover to really dress the package up. Whipple then engineered a custom Stage 3 calibration that increases the maximum spark advance, ignition power from the individual coils, denser air charge from the low temp thermostat, maximized air-fuel ratio in each individual cylinder and increased air flow from the hi-flow filter. Calibration increases torque levels throughout the entire rpm curve while making more peak hp for increased speeds.
Key features:
• Hi-performance ECM calibration
• Low-temp thermostat
• Hi-flow, custom billet flame arrestor
• Polished stainless steel engine cover
• Polished stainless steel CMI Platinum E-Tops
• 5450 RPM limit
• 12% - 15% power increase over stock
• Over 40 foot pounds of torque over stock at 3500 RPM

Stage 2 - $CALL FOR PRICE
The Whipple stage 2 maximizes the power output of the stock engine by running 91 octane or better, increasing the maximum spark advance, increased ignition power from the individual coils, denser air charge from the low temp thermostat, maximized air-fuel ratio in each individual cylinder and increased air flow from the hi-flow filter. Calibration increases torque levels throughout the entire rpm curve while making more peak hp for increased speeds.
Key features:
• Hi-performance ECM calibration
• Low-temp thermostat
• Hi-flow K&N filter
• 5450 RPM limit
• 8% - 10% power increase over stock
• Increased plaining ability with increased torque output
Stage 4 TBA
The Stage 4 goes deep into the engine to maximize the power level out of the engine. Whipple designed this to be a 525 horsepower engine that maintains rugged durability levels and incredible OEM like reliability. Stage 4 utilizes the polished CMI Platinum E-Tops headers, reworked cylinder heads, custom camshaft and valve train components with a custom computer calibration. The results are 525 HP, 600 foot-pounds of torque on 91 octane. Motor starts up, idles and runs like stock with a large increase in power throughout the rpm range.
Key features:
• Hi-performance ECM calibration
• Low-temp thermostat
• Hi-flow, custom billet flame arrestor
• Polished stainless steel engine cover
• Polished stainless steel CMI Platinum E-Tops
• 5650 RPM limit
• 91 octane
• 575 foot pounds of torque
• 525 horsepower
