One of the most popular, and highly controversial, vehicles on the road today is the C7 Z06. First, because the numbers are impressive; 650 hp/650 lb-ft, a supercharged 6.2L V8, and a manufacturer’s claimed quarter-mile times in the high-tens and a 0-60 in under three seconds. But those are just stats.
Recently, these cars have been going toe-to-toe with GT-Rs, Vipers and naturally, European exotic super cars – with mixed results. Some blame the aero, others blame the heat soak of the 1.7L blower, and other more cynical types, accuse the car having a lack of power or being “overrated” from General Motors, despite the fact that baseline dyno numbers have proven otherwise time and time again.
Regardless, the most powerful Corvette ever made, is the best Corvette ever made, and thanks to tuning shops like Late Model Racecraft (LMR), they can become even better. Recently, our friends at Gearhead Flicks caught up with Stephen Fereday & Co. at LMR to highlight their latest Stage II Performance Package for the C7Z, showcasing the package on one of their own customer cars. The numbers produced 743 rwhp on the customer’s 2015 Z06, using LMR’s in-house Dynojet chassis dyno, and we’ve included the recipe of hardware below:
- LMR Custom Cold Air Induction
- American Racing 2-inch stainless steel headers with high-flow cats
- LMR 2-pc Billet Housing 160* Thermostat
- LMR (Overdrive) Harmonic Balancer
- Gates Belt
- LMR Custom Grind LT4 Camshaft
- Double Valvespring Kit & Pushrods
- Cam Phaser Kit
- Crank Bolt
- MSD 8.5mm Wires
- LMR Badging
- Professional Installation
- LMR Dyno Tune
As new technologies emerge and tuners like LMR continue to push the envelope with these cars, we’ll keep you in the loop as things develop. Knowing how well the LS-Series engines have treated enthusiasts over the last 18 years, we’ve barely scratched the surface of what will be possible with the Gen-V LT-based engines.
