The C6 ZR1 was proof that the muscle car catagory was no place for the Corvette. Especially since lapping the Nordschlife in 7:19.63
The Corvette ZR1 engine is a heavily modified version of the LS3 Corvette engine, designated the supercharged LS9 Corvette engine. Producing 638 hp (476 kW; 647 PS) and 604 lbfft (819 Nm) of torque. The LS9 has a sixth-generation Eaton TVS R2300 roots 4-lobe supercharger with intercoolers from Behr, utilizing an air-to-water, dual-brick design. The supercharger’s four-lobe design offers improved efficiency over three-lobe models. To avoid changes to the hood appearance, the supercharger’s output was split into two halves. Each cylinder bank has an intercooler.
The ZR1 flywheel has been improved over the 2008 Z06. The flywheel was upgraded by going from six to a 9 bolt design and cutting off nearly 9.8 ounces (278 grams) for improved throttle response and acceleration. Also an opnions was a 6 speed TR-6060 manual set up.
The differential is a limited slip with carbon and steel plates. The differential uses SAE 5W-80 Dexron LS lubricant. The two half shafts have different diameters (33mm left, 40mm right), designed to prevent resonance during acceleration and reduce the chances of wheel hop. The name of the ride control system is Magnetic Selective Ride Control (MSRC). MSRC is provided by Delphi Automotive Systems from technology invented by the GM Research Laboratories. The system uses two modes of control: Tour and Sport. The ZR1 features a double-wishbone suspension system and Magnetic Selective Ride Control—which adjusts shock-absorber damping in real time to either “Tour” or “Sport” mode.The MSRC shocks are automatically adjusted based on driving conditions and vehicle dynamics (cornering, braking, etc.) for optimal handling. The system is adjusted every millisecond to provide sharp handling during spirited driving, and a smooth ride while cruising. A new magnetic suspension system enables the ZR1 to deliver superior handling and grip to achieve 1.10 g of average lateral acceleration. The front brake rotors are similar to the carbon ceramic design employed in the Ferrari FXX track car. (source wikipedia)
This 1:18 die-cast version comes from Jada.
Accuracy and Design: 8/10
I gave this one of the high score in accuracy mostly because the few detail on the ZR1 were well placed and excecuted. Everything is in the right place from what I have seen in photos online.
Fit and Finish: 7/10
For the most part, everything seems to be in good shape. The places it lost points were the “ok” interior, engine bay, and a few gap issues. Other than that, the paint is stellar, wheels are good, and the shape is accurate.
While the bonnet, boot, and doors are smooth, it doesn´t have spring suspention or a working steering wheel. Points lost there for sure.
A typical ebay, I was able to get this apart of bundle at around $20. Most online seem to be floating around the $40-$60 range at the time.
A quick check online and I couln´t hardly find C6 ZR1. I need you guys to confirm but ones just like this seem to be hard to find.
Final score: 38/50
Should you buy it? If you can find one similar, yes! I feel the ZR1 line will be an epic one in the years to come. Own the first today :]
