- hemi 5.7
I have a 2011 hemi Ram short bed, 2 wheel drive with 5 speed and 392 posi in the rear. Truck ran 14.60 in quarter. Put K&N drop in filter, hd flowmaster 50 series muffler with 4 inch chamber, 3 inch inlet and outlet and Flash-pak tuner set at 93 performance tune. Truck now runs [email protected] mph and according to quarter jr it says now makes 440 hp at flywheel, 50hp up from stock. picked up 6 tenths in quarter seems about right for the horsepower increase. Truck has 120,000 miles and only repair in 11 years was a wheel speed sensor for around $25. Hp was figured using truck weight and quarter mile speed. Truck now shifts at 6,000 rpm stock was 5,600. Think the older trucks responded better without all the torgue management stuff. Hard to believe, but heard 5.7 responds good to minor mods. Had another hemi and a 4.7 in a 2005 and 2006 and did same mods to them. 4.7 used a Hypertech I believe a cortex tuner. Best 3 truks I ever owned and I had both Fords and Chevys.
