The latest in bulletproof twin ball bearing turbocharger technology is just part of the story. Exhaust gasses that feed each turbocharger must arrive at the turbine with the maximum amount of gas energy in order to ensure crisp turbocharger response and wicked power.
APS has designed, tooled and manufactured in high temperature resistant iron, cast exhaust manifolds and turbine outlets. Fabricated components simply look racy but for street durability in excess of 5,000 miles, castings are a must!
Not only are APS’s components cast, they have been designed to maximize flow and close couple the turbine housings to the exhaust ports, for the most efficient transfer of heat energy (which is what actually drives the turbine) and consequently absolutely instantaneous turbocharger boost response. The high thermal inertia provided by the APS cast manifolds is crucial in transferring energy and raising the efficiency of each turbocharger - cast manifolds perform this function much better than any fabricated solution. This is particularly important under spirited driving conditions that require frequent periods of on/off throttle such as your favorite piece of twisty road. Let's face it, when you're in the middle of driving the perfect line through the apex of a corner and you squeeze the throttle through the exit of the corner, instantaneous turbocharger response and that tidal wave of torque is the ultimate rush!
The only reason every other system does not use them is, the cost of tooling. One of the first indicators of a professional turbo system manufacturer is their use of precision machined cast components, particularly exhaust manifolds/turbine outlets.
But engineering excellence doesn't just stop with the exhaust manifolds alone. APS cast Ni Resist High Flow Turbine Outlets scavenge exhaust gasses and ensure the highest possible energy transfer from each turbocharger. In addition, with the optimum internal outlet configuration, the APS High Flow Turbine Outlets deliver unsurpassed turbocharger wastegate performance for rock steady boost pressure.
