Comparison of AV Engineering’s Turbo Kit vs. a leading competitor’s equal length bottom mount kit.  Keep in mind, the AV Engineering Kit has a slightly larger turbo which we attribute a 10-15whp difference in from past Dyno comparison’s.  Datalogs of both manifolds were taken and both engines were running 7.5psi of boost.  As you can see, our kit far outperforms not only in top-end but kills the leading kit in mid-range as well.  Our manifold also holds precise/accurate boost levels which we had issues with minor spiking with the leading competitor’s manifold.  Again, our kit retains both AC/PS unlike any other kit available on the market for the H series engines.

Below you will also find data from our kit vs. the Drag and Treadstone Kit.  Turbo sizing differs so we cannot compare these dyno numbers directly with one another but you can clearly see the efficiency of our kit vs. theirs.
