Secondly, although Fox has a full rigid body (Fox had to say at this point done well), but the suspension was tuned to be relatively soft, cornering roll is more obvious, then, dress up a high hardness spring damping, the effect will be a good many. But it is worth noting that things are degrees. If put strong teeth stirred suspension, with high rigidity body, inevitably driving feel too tight, body bouncing obviously not perfect frame multiply. If you encounter frustrations, driving track of the vehicle will be destroyed. Therefore, the choice to use as much as possible to consider their own areas, to avoid the blind pursuit. Then is the driving force. Original 1.8L, 2.0L, respectively, with 126 and 147 maximum horsepower, more than enough to cope with everyday use, but not to mention how high performance fit Audi Exhaust Manifold. Therefore, the feeling really ambitious, you can consider a higher level. Intake and exhaust a ring, it is much to do. Fox set gas car smaller (comparable peer models), may help to maintain a low torque, but it restricts the intake and smooth high rpm, the replacement or mushroom head high flow style will be improved. The power conversion and interest rates move out of the body, increase the air flow, the original 68mm electronic throttle is a threshold. However, if a polished to increase the inner diameter of the throttle, the air flow will be credited an abnormality is detected fitMitsubishi Exhaust Manifold, so to be replaced, or is considering installing a horse throttle cable 6 (only for older horses 6), though primitive, but convenient and direct. Thereafter, the intake manifold smaller curvature is too large, easily lead to insufficient cylinder intake, maintaining the same low torque design, not suitable for Bigfoot throttle summon fierce turn. The vehicle facelift Cosworth intake manifold, the intake in addition to increased volume, the interior is the use of a class of fourth throat DI trumpet design, a substantial increase in intake efficiency. Venting, 4 1 inevitably cause excessive back pressure, and designed to be very narrow in the crowded city to facilitate the speed, but also the triumph of Fox stumbling block. 4 2 1 replacement, you can take into account the low torque state by the end of the drum back pressure, but also to eliminate poor exhaust landcruiser turbocharger at high rpm, indeed the best policy. If not enough not enough, and that the text of the turbo program, then you have a choice.
