The dyno sheet below is a 2009 Challenger SRT8 stock with a catback exhaust and a cai. The only addition was our stage 2 heads and stage 2 camshaft (218/224 114LSA) and Johan retuned the car. No other changes were made, the car still has the factory headers/cats in place. This is the same combo that Keoni has in his Jeep and it is what we recomend for anyone not running a tq converter. As you can see, this setup makes power from bottom to top making it ideal for a daily driver with good vacuum and no loss of driveability. We are now installing a custom cam that is larger than the stage 4 to go in along with longtube headers to see what the difference is. Stock 3200rpm: 182rwhp/303rwtq Mod'd 3200rpm: 225rwhp/360rwtq Gains @ 3200rpm: 43rwhp/57rwtq Stock 6000rpm: 381rwhp/340rwtq Mod'd 6000rpm: 430rwhp/383rwtq Gains @ 6000rpm: 49rwhp/43rwtq
Nice numbers!!!! Same here Jim, I went with the Stg 2 heads & stg3 cam thru MHP. Let me know how yours turns out too! Can't wait to get them in!!!
