Competing in GTA as well as Grid Life, his grip-hungry beast has obliterated the competition multiple times over by setting an impressive eight records and earning more podium placings. While racing at the famous Circuit of the Americas course in Texas in 2020, Qartoumy easily won his Global Time Attack Super Lap Battle class outright and went on to many more wins and successes. He often pushes the V8 engine’s revs up to the 8,000 mark – not necessarily to make more power, but to improve overall driveability. On track, Qartoumy has already maxed out the PPG 6-speed sequential gearbox as he reaches the rev limiter at 180 mph on 28” tall tires. Mounted just behind each of the front wheels for maximum cool points, the Garrett G-Series turbos were fitted with 1.01 A/R turbine housings with V-band inlets and outlets and flow compressed air through a matching Garrett front-mount intercooler.Īlthough it’s more than capable of putting out 2,000 horsepower, Qartoumy kept his LME-built LS engine at a more conservative supply level of around 900 horses with a mild tune up in the MoTeC engine management system – but a quick turn of the boost controller knob can effortlessly ramp that up to 1,200 and beyond on demand. Qartoumy ran the wicked Corvette in a naturally aspirated configuration at first but soon upgraded it to a twin turbo configuration utilizing two of Garrett’s G35-900 turbochargers. So, Qartoumy turned to the drag racing experts at Late Model Engines to assemble a 7-liter (427 ci) LS7-based powerplant complete with Darton sleeves, Brodix BR7 heads, Wiseco pistons, a Callies crankshaft, and more. Suction cup-like stickability means nothing, though, without proper power to apply it. In the rear, the drag reduction system (DRS) wing works as an air brake when the second element is activated by the air shocks filling up, then re-opens as the killer Corvette picks up speed again. The massive lip up front looks like it’s about to scoop up anything in its way but is strong enough to support the weight of four grown men standing on it. Thanks to the jaw-dropping active aerodynamics package from Affinity Aero, the car produced a whopping 3,260-pounds of downforce when tested at 160 mph. Setting insane lap times on a road course requires a tremendous amount of grip, and Qartoumy’s C6 Corvette has so much downforce that it practically makes its own gravity. Massive aero, monster grip, humongous power, and a wicked intimidation factor all add up to a winning combination for Feras Qartoumy and his 1,200-horsepower twin turbo Time Attack Corvette Z06. Monster power thanks to twin Garrett turbos and monster grip put Feras Qartoumy’s Time Attack C6 Corvette Z06 on the podium. This will allow the supercharger to be more efficient while in boost and cool down faster after high boost runs.ApBig Grip and Big Power for This Monstrous Garrett Turbo Time Attack C6 Corvette Z06 One way to help reduce these intake temps and the risk of damage is to add a more efficient heat exchanger to the system that holds more fluid in the exchange area with more rows/fins per square inch which in turn helps lower intake temps by dissipating heat. Timing lost due to heat above 140* Intake Air Temp sensor 2 can easily rob even a stock C7 Z06 of 25-50+HP on a heat soaked motor. Heat results in a loss in power as well as the possibility of damage to the engine.
When running the car hard, you're making a lot of heat that quickly heat soaks the fluid running through the supercharger trying to keep it cool.
When dealing with Centrifugal, Roots, or Twin Screw Superchargers, there's always the issue of intake temps as heat is a byproduct of compression.
The more dense the intake charge, the more HP your car will make. Whether you're running stock boost on the supercharged C7 Z06 or an upgraded pulley kit, you're already aware of the performance killing heat this engine puts out.
