RAM SRT-10 Drivetrain

Edit

Overview¶

This engine produced 510 hp (380 kW; 517 PS) at 5,600 rpm and 525 lb·ft (712 N·m) of torque at 4,200 rpm. The regular cab, with a total curb weight of 5,130 lb (2,330 kg), reached a top speed of 153 mph (246 km/h), and could accelerate from 0 to 60 mph (97 km/h) in 4.9 seconds, whereas the Quad Cab, weighing 5,618 lb (2,548 kg), did 0-60 in 5.6 seconds and reached a top speed of 147 mph (237 km/h). The regular cab could complete the 1⁄4 mi (400 m) in 13.6 seconds at 105 mph (169 km/h), the Quad Cab in 14.2 seconds at 104 mph (167 km/h). The engine produced one horsepower for every 10.3 lbs of vehicle weight in the regular cab. The regular cab generated .86 g of grip on a 300 ft (91 m) skidpad, while the Quad Cab generated .83 g. The regular cab was rated by the EPA at 9 mpg city/15 highway, while the Quad Cab was rated at 9 city/12 highway. The V10 Viper engine delivered 90 percent of its torque from 1500 to 5600 rpm. The cast aluminum cylinder block had cast-iron liners and cross-bolted main caps. The bore and stroke had been increased over previous Viper models. Compression ratio, firing order, rod length, block height and block length were unchanged from the second-generation Viper engine. The regular cab featured a Tremec T-56 transmission, while the Quad Cab utilized a 48RE four-speed automatic transmission modified from the Ram Heavy Duty transmission. Both regular cab and Quad Cab used a Dana 60 rear axle.

Oil¶

We would like you to run the 0-40 oil. 10w-30 is lighter than we would like._{SRT Engineering Team - Chat Session}

2004 Drivetrain¶

From the beginning, the engineers at Performance Vehicle Operations knew the powertrain was in place. The 8.3-liter Viper V-10 was upgraded for 2003 with new bored and stroked aluminum engine block that increased the Viper's engine's displacement from 488 to 505 ci's and pushed its V-10 power output to 500 hp and 525 lb.ft. of torque. Resting on unique engine mounts, the new engine delivers 90% of its 525 lb.ft. of torque from 1500 to 5600 rpm.

The all new cast aluminum cylinder block has interference-fit cast-iron liners and cross bolted main caps. Both bore and stroke have been increased over previous Viper Models. Block length, height and bore spacing, firing order, rod length and compression ratio have remained unchanged. The Viper V-10 includes a six main bearing crankshaft with increased stroke length and cross-bolted main bearing caps. All new cast aluminum alloy pistons weighing slightly less than prior years despite larger diameters are included, as are new cracked steel connecting rods that are lighter yet stronger.

Cylinder heads on the V-10 are redesigned using semi-permanent mold (SPM) 356 T6 aluminum, with improved intake port, exhaust port and combustion chamber cooling. Lower profile die-cast magnesium cylinder head covers with steel internal baffles and anti-slosh foam also are new for 2003. A single piece central dual-plenum, cast aluminum intake manifold is also new. It boasts shorter runners and single non staged two barrel throttle body for the higher peak hp RPM. The intake manifold is a all inclusive Air and Fuel Module (IAFM) with tubular fuel rails, injectors, sensors, wiring and throttle body delivered assembled and pretested.

A RAM Heavy Duty Cooling system was modified to handle the needs of the new Viper engine. A custom dual exhaust system is mounted to the new exhaust manifolds. The 2004 Dodge RAM SRT-10 focuses it's power through a new HURST shifter and modified version of the Viper SRT-10's Tremac T56 six-speed manual transmission. The T56 is fully sync's with electronic reverse lockout. A modified differential with 4.10 rear axle delivers the hp and torque to the road.
