Since the release of the LS1 engine in the Pontiac GTO and Holden Commodore,
the hearts of performance enthusiasts pounded for an engine enhancement system
that would not only deliver a tidal wave of torque, but also unleash the true
horsepower potential of the LS1.
Right from the start, APS set out to simply annihilate the project 427 C5R Monaro and with over 25 years of turbocharging and intercooling experience, APS has produced what is arguably the ultimate intercooled twin turbo system for the LS1 engine.
A straight forward bolt on totally engineered system that utilizes the latest in water cooled dual ball bearing turbocharger technology and with the industry's largest bar and plate intercooler, APS delivers a system that results in outrageous power and torque right across the entire RPM range.
Best of all, APS delivers uncompromised driveability. Crisp throttle response, tidal waves of torque, silky smooth highway cruising and excellent fuel economy (approx. 8.0 l/100km - 27 mpg US) all add up to an outstanding daily driver - and at your whim, mash the pedal to unleash the beast from within and take pole position in the race for power and torque.
With insane horsepower and monster torque (over double the torque at 3,500 rpm), the APS Intercooled Twin Turbo High Output System performs like a strong 9L Big Block and raises the LS1 performance enthusiast exclusively into the supercar club with 11 second quarter mile performance on street tyres!
The true dual entry design of the APS intercooler system allows for the ultimate in true equal length balanced ducting from each turbocharger to the intercooler. This ensures the optimum utilisation of the intercooler core by spreading the charge air from each turbocharger evenly across the entire intercooler core - This is efficiency at its best!
The end result? Insane horsepower and monster torque (over double the torque by 3,500 rpm). The APS Intercooled Twin Turbo High Output System performs like a strong 9L Big Block and raises the LS1 performance enthusiast exclusively into the supercar club with 11 second quarter mile performance on street tyres!
