Vengeance Racing Whipple Charged C7 Z06
We recently had the pleasure of working with Fadi from Virginia on his C7 Corvette Z06. Fadi came to us looking to make good power out of the LT4 but wanted to change the LT4 blower out for an aftermarket option. After much discussion we decided to go with our Stage 4 performance package and upgrade to the beloved Whipple 2.9L blower. Now this required some additional work in order to get this blower to fit under the hood of the Z06 but Fadi was ready for the challenge and wanted something different. Our Stage 4 performance package consist of: Halltech Stinger Cold Air Induction System Innovators West 9% Overdrive Balancer Vengeance Racing CNC LT4 Cylinder Heads Vengeance Racing Cam Kit Plus – Stage III LT4 Camshaft Nick Williams 102mm Gen V DBW Throttle body American Racing stainless long tube header system with 3” X pipe Vengeance Racing High Temperature protective heat sleeves 160* Thermostat We Also added a few additional modifications to our package including: Weapon X Motorsports C7 Z06 Whipple 2.9L Supercharger System (3.5” Pulley) Circle D 258mm Pro-Series Torque Converter Vengeance Racing Low-Side Auxiliary Fuel System Vengeance Racing E85 Flex Fuel Sensor Kit Alky Control Dual Nozzle Methanol Injection System For the supercharger, we turned to our friends over at Weapon X Motorsports who are producing a Modified Whipple Blower for the C7 application. Once the blower arrived it was time to get to work. Here you can see huge size difference between the OEM 1.7L LT4 Blower and the 2.9L Whipple Blower. The Whipple blower is an excellent upgrade if you are looking at making more power out of the LT4 while maintaining a PD blower. Weapon X did a fantastic job with their kit and modifying the blower to allow fitment on the LT4 in the C7. This is a game changer for sure. We have seen great gains when using the Whipple 2.9L on some of our other LT4 equipped vehicles and knew that this combination would make for an awesome street car with tons of torque for the customer. To feed the Whipple we added a Halltech Stinger Intake and Nick Williams 102mm DBW throttle Body. We installed American Racing Headers feeding into the OEM muffler section to give our customer the aggressive yet manageable sound he was looking for. With the addition of our Stage III camshaft and CNC ported cylinder heads, we landed on a 9% overdrive balancer and 3.5” upper pulley combination which netted us 14psi from the Whipple supercharger. To use our larger Stage III camshaft on the 8L90E transmission, we turned to Circle D and installed their 258mm Pro-Series Torque Converter with a 3,000 stall speed. Once the install was complete we handed the keys over to our tuner. We were able to land at a final power level of 877rwhp and 771rwtq on our DynoJet chassis dyno on E85! With this combination the car is seeing over 700rwtq from 3,000 RPM all the way through the peak of the power band to make for a very fun car on the street. Our customer flew in from Virginia and drove his car the 9 hours home with a smile on his face the entire way.

Bumping up rwhp by about 300, any concerns for the stock internals?
