Well I got the truck dynoed yesterday evening to get some baseline numbers before I get my 4lb pulley and tune installed. I had the dyno done at SS Performance in Tallahassee Florida on their all wheel drive Mustang Dyno. I did three pulls and my horsepower and torque numbers went up every pull. On the first pull the dyno lines were kind of ragged, but they smoothed out on the next two pulls. I had a lot of carbon blow out on the first pull (I don’t get on it very often around town), but the next two were clean. My final numbers where 378rwhp and 444rwtq. The truck is basically stock; I have SCT’s 93 octane tune, Magnaflow Catback, and drop in Airraid filter. SCT’s 93 octane tune probably gave me around 22hp and 17ft-lbs considering what I have seen what these things put out stock. I figure I should be able to get over 400rwhp and 500rwtq with a 4lb lower pulley and good tune. That’s my goal right now. Dyno sheet a pics below.
