Most Powerful Mini on a Stock ECU?! | 520 HP Cooper JCW Big Turbo Prep.
Once again, Lorenzo's (RPMPower) ridiculous R56 Mini Cooper JCW WC50 hits the streets in a very different state of tune than it was the last time I drove it. After a cracked sleeve finally gave up 3+ years into tuning, Lorenzo hit the drawing board to create the ultimate OEM-inspired closed deck block to hold the next wave of boost that'll be thrown at it. In addition, lightweight rods and higher compression pistons complete the bottom end. Today the car sits at a "modest" 520 whp on E60, with a big turbo on the way to (hopefully) propel this force of nature over the 600whp mark. Enjoy!
