This Power Pack was independently tested on a Dyno Dynamics rolling road. Known the world over for being the most accurate and consistent dynos, Dyno Dynamics are also known as ‘The Heartbreaker’ because they are notorious for their low-readings. Our customer’s car produced baseline peak performance figures of 335.5BHP. Following the installation of our manifolds, sports catalysts, exhaust system & ECU Tune, the peak BHP figure was raised to 378.8BHP. An increase of 43.3BHP or 12.9%.
Given that Dyno Dynamics are notorious for giving low readings, it is important to recognize that these dyno results actually represent a BHP gain of greater than 43.3BHP. The manufacturer’s stated output for the 4.3L V8 Vantage is 380BHP. A 12.9% increase over this figure would represent a gain of 49BHP, and a flywheel output of 429BHP.
Similarly, torque has been increased by 35-40ft/lbs from 4000RPM onwards, an increase of around 13-15%. The manufacturer’s stated maximum output is 302ft/lbs @5500RPM. The true flywheel torque figure on this test car is now likely around 345-350ft/lbs. This is perhaps the most significant area of improvement. Downshifting is now much less necessary in order to access the torque band, and this 4.3L car will now outrun a 4.7L later model car.
FITS ALL V8 VANTAGE VARIANTS. PLEASE SPECIFY MY WHEN ORDERING. 2011-ON MY CARS WILL REQUIRE AN O2 HARNESS EXTENSION.
