485WHP-->548WHP, 570BHP-)644BHP 405WTQ-->479WTQ, 443ft/lbs-->524ft/lbs PEAK GAINS: +63WHP (81BHP) +74WTQ (87ft/lbs) MID-RPM GAINS: Over 100WHP (116BHP) Over 100WTQ (116ft/lbs) Following on from our well-documented 675LT Project, the 570S was the next McLaren in the portfolio for us to tackle. At $160,000 less than a 650S, the 570S offers enormous value for money, and along with that a huge amount of untapped potential. The 3.8L Twin Turbo V8 is virtually identical to that of the 650S, leaving a lot of untapped (read:sandbagged) potential. Working with our research and development partners Johnny Bohmer Racing, builders of the world's fastest road car (283MPH Standing Mile Ford GT), we tackled this project with the same thoroughness and attention to detail as the 675LT. The result of several days of dyno testing, road testing, datalogging analysis, our software package is now available to all McLaren 570S owners. The software was installed in conjunction with our XPipe Exhaust system and Catalyst Delete Pipes. PEAK HP GAINS: BASELINE: 485WHP AFTER: 548WHP In terms of 'Power Under the Curve' the dyno charts bear out an even larger & perhaps more significant gain. At mid-range RPM, the BHP and Torque gains are even larger & more significant, show over 100WHP and 100WTQ from 4000-6000RPM, in the mead of the power band. FITS ALL MCLAREN 570S MODELS
