The race for a 10 second S4 3.0 TFSI just got a little more promising as APR sets an 11.1 @ 121.58 MPH in the quarter mile in extremely unfavorable conditions!
On July 30th, APR’s S4 equipped with the Magnuson TVS1740 Supercharger System headed to Montgomery Motorsport Park in Alabama for a full day of endurance testing at the track with temperatures in the 100F’s. Records were first set using Magnuson’s off the shelf TVS1740 Supercharger System with APR’s included 100-octane software, resulting in an [email protected] MPH on Michelin PSS tires.
As the day progressed, the conditions worsened with temperatures reaching above 105F and the density altitude peaking above 4,200 feet. However, despite the terrible conditions, a new world record was achieved. APR’s R&D team swapped the supplied pulley on the Magnuson TVS1740 to a new APR prototype upgrade, scheduled for release in the near future, and achieved an 11.1 @ 121.58 MPH pass!
“Given the extremely poor conditions (4200ft DA) our 11.1 second pass will hopefully lead to a 10 second pass as conditions improve here in Alabama. S Tronic calibration improvements, additional hardware changes (removing the catalysts), and further refinement of the overall package will only push the platform to a place we’ve all wanted it to go.” Said Eric Urness, lead calibrator at APR.
