i remember how poorly these 4.0s responded to mods, mine made 230rwhp with a built block, bbk intake, bbk headers, hiflo cats, and pypes duals, bumped up to 390rwhp with turbos.......then blew the engine on nitrous lol, good looks on urs though, even at 200rwhp they pull very decently
@jerryzkidz99 Since the horsepower is measured at the wheels in a dyno test, and not the flywheel, the numbers are almost always lower due to driveline power loss. A 4.0 SOHC is rated as 210 HP / 240 TQ but that is roughly 180 RWHP and 200 RWTQ, respectively, (at the wheels). In other words his/her mods increased horsepower by 8 and his/her torque by 5.

Why do the numbers seem so low with all those mods??
