Bolt-In 550HP All (Electric) Motor!

New Tesla crate motor can be bolted in place using LS V-8 small block mounts - is this the future of tuning?

Oct 6, 2020

Rodrez: Years ago, the thought of powering anything other than a commuter with an electric motor, like those found at the heart of the wildly popular Tesla lineup, was unheard of. Ours is an industry that embraces change, so long as it's not too much change; that is, progression and technological breakthroughs, usually related to finding additional power or satisfying other performance parameters, are often ignored before being debated and eventually accepted. In terms of electric power replacing internal combustion, we seem to be deep in the debate stage, but something like this Tesla crate motor option might push things forward a tad. Bolted in place using V-8 small block mounts—something our industry also despised yet eventually accepted and can now be found in drift, street and even show car builds—this new crate motor option may spawn a whole new movement within our community.

As reported by MotorTrend's Alexander Stoklosa: The term "crate engine" has long been used to describe engines you could buy (typically modified) and install in the car or project of your choosing. Why the name, though? Because the engines ship in crates. Often, the word "engine" is used interchangeably with the word "motor," a casual oversight of the distinction between an internal-combustion engine and a motor, which we typically use to describe an electric power source. Until now. Go ahead and call EV West's Revolt Systems Tesla electric powertrain swap what it is: A crate motor.

This new crate motor option is a bolt-in setup gunning to replace one of the most common crate engine choices out there in GM's small-block V-8. That's because the EV West Tesla powertrain bolts up to small-block V-8 engine mounts and can be hooked up directly to a driveshaft.

Speaking of V8s, Tesla and EV-powered builds:

V8-swapped S15

The so-called Revolt Tesla Crate Motor appears to include not only the electric motor from a Tesla, but also an inline gear reduction where a traditional transmission would bolt up behind an engine, along with a universal joint waiting to be fixed to a driveshaft. As with EV West's other available motor kits and such (the outfit offers EV conversions for a variety of classic cars), the battery and control unit for the setup appears to be sold separately, and all of the components will be available individually. Not a cheap endeavor by any means.

Previewed in a Facebook post by EV West, which also included photos taken at the Bonneville Salt Flats, the new kit is really a combined effort by EV West and Revolt Systems, a new company being started to provide the necessary conversions of Tesla powertrains to this new longitudinal layout. According to EV West, the original Tesla Model S drive units have to be stripped down, the differential casting cut free, and the motors smoothed up and bolted to a new aluminum gear reduction.

The crate motor produces a claimed 450 kW, or 550 hp. On Revolt's website, it notes the forthcoming Tesla drive kit includes "a highly modified 400-kW Tesla Model S motor producing approximately 533 hp with over 800 [lb-ft] of torque at the yolk." So, either way, expect prodigious output from the motor.

A separate conversion kit offered by EV West includes what sounds like the same 400-kW Tesla Model S motor along with a different (more stock-appearing) gearing setup; it runs $11,900. The small-block-ready version has a custom gear setup (that longitudinal arrangement pictured here, which is distinct from the off-the-shelf transverse layout used by Tesla). In any event, consider this a cool addition to the crate-motor world-a plug-in Tesla powertrain that can fit virtually anywhere a small-block can. That leaves finding room for a battery as the main challenge for would-be EV crate motor converts.
