When selecting gearing for an N14 Plus engine hauling over 80,000 lb GCW, one should consult an authorized Cummins representative. Performance of heavy-haul vehicles is application dependent. A price of 5k would be insane, and Cummins would never make a penny. Go price any gas crate options and you will see it's right on par.

To understand the relative differences among various gearing combinations, one should consult an authorized Cummins representative and request a Vehicle Mission Simulation™! (VMS). When considering these combinations, one should be aware that: (a) the increase in maximum vehicle speed will be minimal, (b) the fuel economy benefit associated with lower cruise rpms is difficult to measure, and (c) most important, vehicle grade-climbing capability will be adversely affected resulting in increased gear shifts. Note: Lower numeric (faster) axle ratios are sometimes considered to obtain higher maximum vehicle speeds and lower engine rpm at the vehicle's normal cruise speed. A qualified truck salesman or a Cummins distributor can provide information on available transmission top-gear and drive axle ratios in addition to the actual tire revolutions per mile for a specific tire to be used on the drive axle. It is important to utilize actual ratio and tire rev/mile information in selecting gearing combinations. Rpm = (65 mph) (trans ratio) (axle ratio) (tire revs/mile) The formula for determining engine speed (rpm) at the 65-mph checkpoint for a selected gearing combination is:

For vehicles that will operate below 65 mph and maximum fuel economy is not required: Select a gearing combination (transmission ratio, tire revs/mile, drive axle ratio) that will result in approximately 1550 rpm at a 65-mph checkpoint.

For vehicles that will operate at or above 65 mph: Select a gearing combination (transmission ratio, tire revs/mile, drive axle ratio) that will result in approximately 1450 rpm at a 65-mph checkpoint.

For maximum fuel economy (mpg): Select a gearing combination (transmission ratio, tire revs/mile, drive axle ratio) that will result in approximately 1450 rpm at a 65-mph checkpoint.

Increased starting torque delivers more 'lift' the instant the clutch is let outĪdded power means improved high-speed performance even when heavily loadedĪvailable as an option, ESP Plus gives drivers a burst of power when climbing a steep grade. With more advanced electronic engine controls and hardware improvements, N14 Plus engines deliver more miles per gallon Today, Cummins formally announced the long-awaited crate engine program called Cummins Repower as a means of offering brand new engines from the factory direct to the consumer market. Weight: 804lb dry (engine only), 899lb fully dressed (with after-treatment system)Įmissions: Engine-integrated cooled EGR system, diesel particulate filter (DPF), and selective catalytic reduction (SCR) system requiring the use of diesel exhaust fluid (read: AdBlue).Based on the performance of over 150,000 N14 engines already out on the road, this engine is setting the standard in durabilityĪn outstanding reputation for long life-to-overhaul, teamed with easy uprating capability to higher horsepower, adds up to maximum resale valueĬELECT Plus has an advanced electronic control module (ECM) that provides enhanced customer features, improved engine controls, including automotive-style cruise control Valvetrain: 32-valve (4 valves per cylinder), dual overhead camshafts (DOHC) Injection: 29,000 psi high-pressure common railĪspiration: Variable geometry turbocharger (VGT), intercooled Thus, chances of getting a brand-new motor is small (unless you know a guy who knows a guy).ĭisplacement: 5.0-litre, 304 cubic inchesīore x Stroke: 3.70″ x 3.54″ (94 mm x 90 mm)Įngine Block Material: Compact graphite iron (CGI) The reason the Cummins ISV 5.0-litre V8 is such a hard engine to get a hold of, is that Cummins and Nissan have an agreement in the US, that means every ISV 5.0-litre engine off the assembly line must go to Nissan and be used in the Titan utes, and some motorhomes (aside from the crate motors that go to Nissan as replacements). Insofar as price is concerned, they won’t be ‘cheap’, with the expectation they will be up around the same price as the rather prolific Duramax.

West Australian company Cummins Imports Australia have just announced on their Facebook page that they have a ‘couple’ of used example with very low mileage.
