Vengeance Racing adds a 2.9 liter Whipple twin screw to a 2017 Chevrolet Camaro ZL1 LT4 and makes 909 rwhp

The Chevrolet Camaro ZL1 with its 650 horsepower LT4 motor is no slouch in stock form. It will do an 11.5 @ 120 in the 1/4 mile stock. It is also pretty heavy though at 3926 pounds. For owners wanting to go faster ditching the factory Eaton TVS1740 blower make a lot of sense.

A 2.9 liter Whipple is much, much bigger. It also can be spun harder.

Here is what they did to the car:

· Whipple 2.9L Supercharger System
· Vengeance Racing CNC Ported LT4 Cylinder Heads
· Vengeance Racing Stage III Camshaft Kit
· Vengeance Racing Custom Cold Air Intake System
· Vengeance Racing Engraved Valve Covers with Coil Relocation
· Kooks 2" Longtube Headers with Kooks axle-back exhaust system
· RPS Triple Carbon Clutch
· ATI 22.5% Overdrive Balancer Kit
· Vengeance Racing Custom Auxiliary Fuel System
· AlkyControl Dual Nozzle Methanol Injection Kit
· BMR 1" Lowering Springs
· Vengeance PCM ECU Calibration

They tested it on 93 octane, E85, and C16. Surprisingly, leaded C16 race gas provided the best numbers:

BoostAddict.com does not doubt Vengeance Racing but they should know better than just posting the peak numbers. Where are the graphs?

Regardless, the LT4 is simply begging for a bigger blower and a 2.9 liter twin screw is not a bad way to go.

Those whipple supercharges ain't no joke. There's another ZL1 with similar setup, tuned by Houston House of Power and it made 922 whp and 907 wtq. He's in Instagram as "zl1_tommy".
