Of the 5,703 cars ever made, one of them paid Evolve Automotive a visit for a few revisions. Having been stored for an extended period, the soft-top convertible was in need of some pampering underneath the hood.<\/p>\n<p>At first, things weren\u2019t looking too good for the <a href=\"https:\/\/www.bmwblog.com\/2022\/03\/05\/bmw-8-series-e31-supercharged-s62-engine\/\">S62<\/a>. BMW rated the engine at 395 horsepower back in 2000 when the Z8 went on sale. However, the dyno test revealed it was only making just under 350 hp. The result was particularly worrying considering the 4.9-liter V8 should\u2019ve actually made over 400 hp considering the car had some exhaust upgrades from Supersprint.<\/p>\n<p><noscript><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-medium wp-image-350342\" src=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-830x553.jpg\" alt=\"BMW Z8 test drive 16 830x553\" width=\"830\" height=\"553\" srcset=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-830x553.jpg 830w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-768x512.jpg 768w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-1024x683.jpg 1024w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-300x200.jpg 300w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16.jpg 1920w\" sizes=\"(max-width: 830px) 100vw, 830px\" title=\"image of BMW Z8 test drive 16 830x553\"\/><\/noscript><img decoding=\"async\" class=\"lazyload alignnone size-medium wp-image-350342\" src=\"data:image\/svg+xml,%3Csvg%20xmlns=%22http:\/\/www.w3.org\/2000\/svg%22%20viewBox=%220%200%20830%20553%22%3E%3C\/svg%3E\" data-src=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-830x553.jpg\" alt=\"BMW Z8 test drive 16 830x553\" width=\"830\" height=\"553\" data-srcset=\"https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-830x553.jpg 830w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-768x512.jpg 768w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-1024x683.jpg 1024w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16-300x200.jpg 300w, https:\/\/cdn.bmwblog.com\/wp-content\/uploads\/2019\/08\/BMW-Z8-test-drive-16.jpg 1920w\" data-sizes=\"(max-width: 830px) 100vw, 830px\" title=\"image of BMW Z8 test drive 16 830x553\"\/><\/p>\n<p>Evolve noticed one of the cylinders was misfiring, which wasn\u2019t all that surprising since it\u2019s a common issue with this engine. The V8\u2019s mapping was updated and the spark plugs were changed as well. It was then time to put the Z8 back onto the dyno and quantify the power gains. The rear-wheel-drive machine was in a much better condition following these changes. The dyno run rated the naturally aspirated engine at 432 hp.<\/p>\n<p>The British aftermarket shop proceeded to apply its own stage 2 kit in a bid to extract more power from the BMW Z8. The end result was a healthy 440.6 hp, thus representing a substantial bump in the output of 92 hp compared to the first dyno run. It\u2019s safe to assume the owner is now quite happy with how Evolve fixed the engine.<\/p>\n<p>The roadster has been dormant for a while and will be taken on a trip around Europe now that summer is almost here.
