As tuning progresses there are many reasons behind the use of cams for increased performance gains which also depends on the application as you will not get a complete overall tune for all uses. So you have to choose the cam profile to suit your needs. For example there times when high RPM is desired but without the larger profiles then achieving the desired performance result at that RPM can be hard to achieve. Sometimes the exhaust backpressure is too high which is not only the cause of the exhaust system but also the choice of camshaft profile used may be too large. Controlling the exhaust back pressure is especially important with the 4G63 as it is greatly affected by the camshaft profile. Disregarding some specific performance aspects will still require you to focus on maintaining a balanced engine exhaust back pressure. This is the main reason why we use Tomei Powered camshafts because we can achieve superb exhaust pressure control after repeated test results. With the wide selection of PONCAM and PROCAM range in the LASH or SOLID range helps to achieve the right performance target to suit the userfs needs. These camshafts are the best overall balance for satisfying the desired stable idling, mid range torque and high RPM range. I especially believe that the PONCAM point is when recommended to users they can experience at firsthand the broad feel and rise in boost response with the turbine. |
