LHE Engine Showroom. (Revised)

LHEs (Left Hemisphere Engineering) goal is to make simple engines that are reliable as possible, as modular as able, cheep as conceivable, and ready to run on any form of petrol you stick in them.

Re: LHE (Left Hemisphere Engineering) Engine Showroom.

1964 X-Modular E-Series Motors.

The X-Mod family is designed with a maximum bore/stroke of 81.2mm x 91.4mm, this bore stroke combination allows for a moderate displacement engine in a small physical package, all E-Series X-Mods feature a 76.2mm bore but preserve the maximum stroke of 91.4mm giving the E-Series a Bore/Stroke ratio of 0.833:1, this design allows the small displacement family to produce decent torque though the whole operating range. To prevent piston slap, the X-Mod engines feature deep skirts on the pistons which help promote even wear across the cylinder walls

Image

The X4-M64-E76.2U70 Is the initial run of the X4-M, and was sold for use in small equipment and boats, with a peak power of 70.0 hp @ 4700rpm and 89.8 lb-ft @ 3700rpm. With only a production unit cost of 15, and a material cost of $578.45 the X4-M E-Series is an excellent choice for equipment and even personal projects
Image

The X8-M-E76.2U140, similar to the X4-M, the X8-M is essentially two X4-Ms mated to one crossplane crankshaft, it produces 140hp @ 4700rpm, and 179 lb-ft @ 3600rpm, with a production unit cost of 26.1 and a material cost of only 754.39, the X8-M is an excellent platform with which to build from for those who want to get into inexpensive engine swaps for their imported cars, or garage made sports cars.

Re: LHE Engine Showroom. (Revised)

Announcing the all new LHE 'Big Block' Modular engine.

The SX-Modular Family
Image


The SX-Mod Family is built on a family capacity of 93.9mm x 97.8mm featuring a Bore/Stroke ratio of 0.960:1, and the E-Series features a bore reduction by 5mm to 88.9mm (3.5 inch) which takes the Bore/Stroke ratio up to 0.908:1. Similar to the smaller capactiy X-Mod, this is done to the E-Series to promote more usable torque, and by use of a smaller displacement, a more economically minded power plant. The large displacement SX-Mod family was brought about by a need for larger displacement and higher torque devolping engine to power larger platforms, such as the Orbital, and Listle where both were outgrowing the small displacement X-Mod family.


The SX4-M74-E88.9U111 is a 2430cc Inline-Four which devolops 111hp @ 5000rpm, and a generous 135lb-ft @ 2500rpm with a very smooth and equal power curve.
Image

The SX8-M74-E88.9U221 is a 4859cc V-Eight which devolops 221hp @ 5000rpm, and an adaquate 267lb-ft @ 2400rpm.

Re: LHE Engine Showroom. (Revised)

Cleaned up presentation, first E-Series for X-Mod, and SX-Mod engines on display. From henceforth, I will display all engines built for community challenges here.

Re: LHE Engine Showroom. (Revised)

The engine used in the 2011 Comstar which managed to bring home second place in Conans Ultimate Car Challange 'Dads Limbo'

The LHE X4M2011-E76.2U144T

Experimenting with turbocharing on an economy platform, LHE built this version of the X4M E-Series with light weight pistons, a very lean 14.7:1 AFR low compression slightly large turbo which delivers 1 bar of pressure.

The result was a lively little four cylinder which offered great economy, but lacks the refinement of other smoother running motors.

Re: LHE Engine Showroom. (Revised)

The engine used in the 2015 Elephant, entered in DoctorNarfys Man With a Van

The LHE SX8M15-E88.9-ETDFI-U340

Built on the SX8 E-Series, using Hyper Pistons, cast rods and crank, the standard 14.7:1 AFR for all E-Series, and two turbochargers which are quick to spool up and deliver a continuous 0.5 bar.

Designed for towing and hauling, this engine is ready for fleet sales.

Re: LHE Engine Showroom. (Revised)

LHE Is making the First gen Iron based X-Mod engines available for all providers, all engines presented are in standard parts list options.

All LHE engines follow the 1974 Lead ban, and production units after 74 follow all emission guidelines.


All X-mod blocks are built on a 81.2mm x 91.4mm layout, both the E and P series blocks are identical, however E-Series blocks have a reduction sleeve inserted to bring the bore down to 76.2mm

Image

The Standard trim X-Mod E-Series, both the four and eight cylinder versions have the following common parts.
*Pistons
*Connecting Rods
*Fuel pumps
*Carburetors (Jetted for appropriate size)
*Cylinder Heads
*Exhaust Manifolds


The 1965 X4M E76.2-65-C4B-U62, and the X8M E76.2-65-C4B-U126
