Motor Trend and HOT ROD Magazines recently shared an article I wrote talking about the new twin turbo LT7 engine in the 2025 Corvette ZR1.
GM recently dropped the details on the new 2025 C8 ZR1. As an engineer who has worked in both OEM development and aftermarket performance, I’m nothing short of impressed. I spent the last quarter-century bouncing between walking the aisles of the Performance Racing Industry show and releasing engine calibrations that have been driven by millions of unsuspecting users around the world. I have seen lots of 1,000-hp engines. I have had lots of engines go to production after passing emissions, durability, NVH, and safety standards. I haven’t seen very many that did both.
