Tunning by HKS TW

GRF This car really just introduced caused no small stir, but watch outsiders experts see Road. Familiar Impreza fans will know, Fengyun 2.5 liters engine known as the red-headed maximum output of 300hp, in fact, and in 2003 the US regulatory GDB sinking B25C identical on horsepower machine is vulnerable, the original maximum output only 248hp while in the modified stores converted under the first phase, currently more can squeeze out maximum power 280hp, the overall combat effectiveness is being less than the original! audi s3 1.8 turbocharger

Original EJ257 after a promotion surrounding, more than the original 32hp / 7kgm maximum output, HKS Kansai air manifold box can be effectively cut off from the heat source, when full sprint to ensure better oxygen intake, not because of high temperature reduce the lead to engine performance degradation.
 
Fengyun EJ257 is not really new engine, the maximum power with previous generations carry the same B25C the GDB, the original maximum power 300hp / 41.5kgm, Renault megane turbocharger in 2500c.c. Displacement to help out at around 2000rpm that is sustainable in the play about 30kgm torque, transmission, though still high reliability adopted six-speed design, but in order to cope with the low-speed torque bias B25C output characteristics, particularly gear ratio will be fully relaxed, reach may extend the power of the effect, but each seems to change a shift power soft for a moment, so GRF although the turbocharged design, but the actual run up is quite smooth, as compared with the earlier GC, cool degree may be greatly reduced. In view of this, the owner KEN GRF is in the car along with the ten thousand kilometers later, after the loss of the power shift feel quite satisfied, so please refit the store to the car to do the planning modification procedure, but the original Fengyun EJ257 Factory unchanged when made only on horsepower machine 248hp / 38kgm, it is no wonder each for a file on boring some, the ultimate goal in order to squeeze 400hp HKS 3037S, the present stage is based on the periphery of the auxiliary to enhance the power, so in order to By providing a higher oxygen content, HKS intake group has become the primary modification. Also: "As boxer engine temperature difficult to discharge, in order to effectively reduce the intake air temperature to the power of influence, in particular the use Kansai air manifold box isolated heat source, intake air temperature can be reduced by more than 20 degrees." HKS exhaust section is designed for mining GRF launched Legamax Premium, the wind is picking Taiwan faction Invidia products, this way intake and exhaust flow rate are also able to effectively enhance, boost the value aspect is the use of EVC V current pressure set set at 1.3bar, and finally with the V Pro 3.3 will be a whole series adapted from the stage can squeeze out maximum power 280hp / 45kgm of.
