The Best Bolt On turbo available for the EVO 4-9.
The stock turbo for the EVO 4-9 series was already an improvement from the previous models. Since the turbo design is now reversed there has not been any bolt on turbos made readily available on the market until now. Our all new ARMS M7960 turbo greatly exceeds all performance aspects over the stock unit and delivers the most power and torque gains possible on a direct bolt on replacement turbo. With the design aspects of this ARMS turbo it is a good all round balance for various engine setups through all power ranges.
FEATURES
* Flat Primary Exhaust Pressure.
The boost build up is neither sluggish nor abrupt; designed to be natural and smooth.
* Response Equal to Stock Trim
Generally, a larger turbocharger relative to stock, results in decreased response of the engine. However, this model has managed to keep the response equal to that of the stock trim by matching the most ideal turbine and compressor wheel. Countless hours of testing was of course performed to achieve these results.
* Increased Peak Power
To achieve an increased peak power with the various restrictions such as the turbo size limit is considered a great achievement. We are also proud of the perfectly instant response where there is no lag and no abrupt boost pressures
* Maintains Boost Pressure at High RPMs
It is evident that the stock turbocharger cannot maintain or extend boost pressure above 5,500 RPMs. The M7960 has the capacity to far extend this limit, making it an ideal step for further advanced tuning
