  1. Whipple Supercharging my 5.7L R/T blog

    Challenger Performance Mods - Engine - 5.7L HEMI
    Dropped it off at my speed shop yesterday. We did a Dyno before to see what kind of numbers I got from the supercharger itself. I made 352hp and 387tq with kooks 1 7/8 headers , hi flow catted mids and Corsa the rest way back. And a cold air intake. I'm a 6mt I'm putting a Whipple 2.9L going...

    I'll update this thread after I get it back and get back home--probably around the middle of July, but here's the baseline dyno they ran today. I have a 2016 A8 R/T. 348 RWHP, unmodified except for a CAI and Borla cat-back system. I'm looking forward to the "after" result. :)
