For a while now I’ve had a Eurodyne Boostmanager Plus+ water/methanol injection system on hand courtesy of FrankenTurbo with a Snow Performance pump.  Finally I am getting around to having it installed, but I’ve still got

a ways to go before I have it fully operational and can make an assessment of the system.  Above is a picture of a 2.5 gallon fluid reservoir and the Snow Performance pump mounted to a removable plate in the trunk.  The fluid supply line runs under the driver’s side lower molding, beneath the dead pedal, and out through the rubber grommet in the footwell following the driver’s side frame rail, where it will then tee into either side of the APR bipipe.

Here is the BoostManager Plus+ mounted to a removable panel on the passenger side.  Beside the BoostManager is mounted an Innovate LMA-3 datalogger.

Lastly, here’s the current state of the engine compartment.  There’s still some work to be done installing an oil catch can as well as connecting the LMA-3 and BoostManager Plus+.

Based upon some of the latest flow testing I have updated the composite pressure drop chart.  The goal of the chart is to show the relative contributions of various components to the overall pressure drop experienced pre and post turbo and help guide purchase decisions.

Adding the flow testing of the intake manifold is problematic due to the way that air flows through the part when operating.  Tests on the flow bench consisted of single runner and all runners open, neither of which accurately reflects the operating conditions on the car.  As a compromise the average flow through a single runner at 250 CFM was used to establish the pressure loss value used on the chart.  Be aware that the magnitude of contribution from the intake manifold could be quite a bit different than shown below.

This item arrived today, a Loba Motorsport Intake Manifold for the Audi B5 S4/RS4.  Flow testing will be performed soon.
