Body mods were kept conservative. An LG Motorsports heat extractor hood improves airflow through the engine compartment.
Once the powertrain was assembled, Geoff applied his tuning skills to extract the system's potential. The goal was for the engine to make 1,000 hp. By dialing in the system on NLP's in-house Dyno Jet 224 XLC Load Control dyno, Geoff surpassed that mark, and recorded 914 peak rear wheel hp at just over 6,000 rpm, well beyond 1,000 engine hp when factoring in frictional driveline losses, normally around 18 percent. Check out the dyno sheet. The engine has more than 800 rwhp on tap from about 4,750 rpm on up. And this from a perfectly streetable engine content to idle in traffic with the air conditioner on.
The 20-spoke alloy OZ wheels...
The 20-spoke alloy OZ wheels provide a good window for viewing the Stoptech brake system. For an autobahn stormer such as this, good brakes are a must.
But this Corvette was not built with American roads in mind. It was built to burn up European expressways like Germany's famed high-speed autobahn. You know the problem: You're enjoying some happy throttle time on the European super slab when you come up behind a bottleneck of slow-moving Lambos or Ferraris. What to do? In this high-speed hauler, it's never a problem. This Corvette has hit 219 mph with more to go. So just give 'em a courtesy flash or two of the headlights, then step into as much boost as you have nerve for. You are go at throttle up. Swing into the passing lane and watch the problem disappear in the rearview mirror. Maybe kick the air conditioner up a notch or two. Life is good. Should the slow movers catch up to you at your next exit, it's up to you if you want to pop the hood. You might as well. It'd take a keen eye to spot anything tell-tale. The looks on their faces would be suitable for framing.
