Message be the same for all setups.

Different compressor wheels operate at different efficiencies for a given pressure ratio and massflow. Additionally, each turbocharger compressor type will have a different maximum pressure ratio and massflow it can produce.

If I were to guess on the results:

@400RWHP: increase of 12RWHP
@500RWHP: increase of 22RWHP
@600RWHP: increase of 35RWHP
...and more

The difference in gain as power increases will be exponential. In addition, the spoolup response will also be exponentially improved - the turbos will reach target boost earlier in the RPMs, which will also improve peak torque. The biggest difference will be in the area under the curves though - the difference will start from as soon as the throttle goes WO all the way to the rev limit.

As always, in order to get an accurate measure of the performance benefit from a new inlet system, dyno testing will have to be performed. Over time we will be able to see the trends associated with the use of this new system on cars with a variety of different modifications.

We will be dyno testing this new inlet system within the next couple of weeks - both before and after results to see the effect. The vehicle this will be tested on is putting down around 400RWHP on pumpfuel and 500RWHP on racefuel, so we will have a decent range to test this system on. I anticipate that in short time after release we will have many more dyno charts to add to the collection which will show even bigger results for higher HP cars.
