[QUOTE="Power Hungry, post: 555849, member: 1375"] Anything that is going to increase wastegate tension is going to increase backpressure. That's not necessarily a bad thing. What's really important is (1) That the backpressure is not becoming excessive, and (2) You are maintaining an efficient Backpressure/Boost ratio. The closer you can get to a 1:1 ratio, the more efficiently that turbo is functioning. If you're increasing backpressure, but your boost isn't increasing at the very least at the same rate, all you're accomplishing is creating a restriction and ultimately a reduction in power and performance. There is a balance here based on the driving needs of the vehicle owner. For better response and good low to mid RPM perofrmance, a tighter exhaust housing would more beneficial. For higher RPM applications and better EGT management, a less restrictive type of housing might be a better choice, although there will be some definite low RPM performance losses. Where the G2 excels lies not only in the fact that it's lighter than the cast wheels so it spools more quickly, but its design provides more efficient airflow at the same backpressure which results in improved mid-high RPM performance. It's really quite exciting to see similar results on another vehicle. [/QUOTE]
