A 1200 hp Z06 Corvette sound pretty impressive, doesn’t it? Well, this car really is. It is a 2007 Corvette Z06 and it belongs to Marcus Ostlid from Sweden. He is part of Team Insane Racing, their other project being a crazy Chevy Monte Carlo built for drag racing. I bet in the US this would not be seen as an exotic project, but in Europe a blown Corvette track car isn’t something you see very often. I mean 1200 hp for drag racing is ok, but for a track car it requires a different set of balls.
Power comes from a 38ci LSX engine and a ProCharger centrifugal supercharger. Crazy as it might seem, this engine was swapped into this car. Marcus has been racing a C5 Corvette for seven years, so when he got everything right he started looking for a newer model. In order to have a reliable engine, Marcus installed AFR CNC-machine heads, an Eagle stroker crank, Eagle H-beam rods and forged JE pistons. The engine dumps gases through American Racing 2’ headers and a custom exhaust that spits out through a rear body panel instead of the rear bumper.
The engine also benefits from a SLP oil pump, T1 Dynamics 1,000 cc injectors, a methanol/water injection system, an Evans waterpump, a front mounted intercooler , two TiAL 50mm valves and a secondary Weldon 2035 racing fuel pump along with a 2-liter catch tank and a racing regulator. The gearbox is a Tremec T56 6-speed unit, other mods including a RPM heavy-duty main shaft, a Spec Super Twin clutch , a Tick Race adjustable master cylinder with a Race slave cylinder, a DTE driveshaft, a DTE differential strut and last but not least a DTE Stage 5 3.42 differential.
For track days the car is equipped with 12×18’ OZ Racing Allegerita HLT wheels with Hoosier slicks, measuring 280/680/18 upfront and 330/710/18 in the rear. And yes, Marcus also races this car in the streets, so he has a set of 12×19’ OZ Racing Superleggera wheels wrapped in Toyo Proxes R888 measuring 305/30R19 all around. In order to cope with such wide tires the car is equipped with a Loma GT2 widebody kit made out of carbon fiber and it is 80mm wider than the stock body. The front splitter keeps the cars nose glued to the ground while the APR carbon fiber wing does the same thing with the back end.
Braking is provided by AP Racing front 6-piston calipers with 2-piece 370mm rotors and rear AP Racing 4-piston calipers with 2-piece 358mm rotors.
