2022+ Honda Civic 1.5T Silicone Hose Upgrade Release & Dyno

            Last week we strapped our 11th Gen Civic 1.5T Touring to the dyno to collect some baseline numbers. Conveniently, our Product Development Team managed to design and receive a prototype a Silicone Intake Hose Upgrade just in time for testing. We were able to install this prototype hose the same day and use before and after numbers for product gains.

            Both dyno sessions were performed on the same day using a DynoJet 224X at an approximate ambient air temp of 95℉ and an elevation of 1000ft. Each run was performed in 4th gear between 70 and 90 MPH. The horsepower reading was recorded with an X-axis value of speed because we were unable to obtain a tach signal from the car during the dyno session. Because this car has a CVT, we are only able to collect consistent data over a given MPH/RPM span. Additionally, we were unable to obtain charge temperature, intake air temperature, or fuel trim data. At the time of testing, datalogging was unavailable for this platform due to a change in ECU protocol from the previous generation. Both Hondata and KTuner are working on a datalogging solution for the 11th Gen platform, as well as many other future capabilities. The dyno graph here appears unusual, because the CVT transmission holds the engine at optimum rpm while increasing wheel speed. All runs were performed in the same speed window and gear such that the load on the engine was consistent across all data sets.

            In order to obtain exact average values, we exported the data from each run, and compiled them into a spreadsheet to better understand how the car was behaving at each data point.

Stock Baseline vs Silicone Intake Hose
Stock Baseline vs Silicone Intake Hose
For the set of dyno runs with the completely stock car, we saw an average power across all runs of 165.4 HP and an average peak power of 168.6 HP.
With the Stage 1 Prototype Intake that included a 3D printed intake hose, 3D printed resonator delete plug and OEM panel filter, we saw an average power of 167.7 HP and an average peak power of 171.3 HP. This is an average gain of 2.3 HP and an average peak gain of 2.6 HP.
Comparing the two dyno sessions in their entirety, we saw maximum mid-range gains as much as 4.6 HP at 82 MPH. With a silicone intake tube, billet aluminum resonator delete plug and a PRL drop in panel filter, we are expecting gains up to 5-6 HP on completely stock ECU mapping. We’re pumped with these gains for the dollar value. For those looking for a bit more out of their 11th Gen Civic, stay tuned for more details and development on our full intake system upgrade in the future!

            We will be selling the Silicone Hose Upgrade, Drop-In Panel Filter Upgrade and Air Box Resonator Delete Plug separately as individual products, and together as a complete Stage 1 Intake System Upgrade. Silicone Hose Upgrade Kits are now available! https://prlmotorsports.com/products/2022-honda-civic-1-5t-silicone-intake-hose-kit?_pos=1&_sid=bc34dff50&_ss=r
