Cost Analysis of Constructing a Go-Kart Engine from Harbor Freight: $8,725 Overall Expenditure

Harbor Freight is the go-to option for budget-conscious DIYers throughout the United States. However, just because it’s Harbor Freight doesn’t imply that projects using their products can’t be expensive. I’m not solely referring to bathroom renovations, as showcased by this remarkable Predator 670 project from Red Beard’s Garage. He began with a $950 V-twin engine and subsequently invested more into it than what some individuals spend on their LS V8 builds.

To clarify, this is anything but ordinary. It must be the most outrageous Harbor Freight engine project I’ve come across, which is why I wrote about it the previous week. The individual behind Red Beard’s Garage installed components on this that I’d never even think of purchasing for a go-kart. The comprehensive list includes…

  • Holley Sniper EFI system ($1,400 including custom USB cable)
  • Upgraded camshaft ($530)
  • Garrett GT1241 replica turbo ($400) and oil accessories ($140)
  • Billet pistons ($460) and connecting rods ($290)
  • Alternator package ($400)
  • Billet flywheel ($380)
  • Electronic ignition ($340)
  • Head modifications, including porting, milling, and O-rings ($300)
  • Billet valve covers and rockers ($270)
  • Fuel cell ($200)
  • AN hoses ($200)
  • Intercooler core ($160)
  • Exhaust manifold ($140)
  • Intake adapter ($130)
  • Springs and retainers ($125)
  • Intercooler piping kit ($110)
  • Intercooler pipe couplers ($80) plus miscellaneous ($40)
  • Boost reference fuel regulator ($75)
  • Fuel pump ($70)
  • Chromoly pushrods ($65)

Factoring in the cost of the Predator 670, the grand total amounts to $7,225. What!? And it becomes even pricier once taxes and shipping are included, bringing the total to $8,725.

Red Beard’s Garage

The host already owns a supercharged Predator-powered go-kart in his garage. He intends to evaluate this build’s performance against the other boosted one after installation. According to his last video, he will be running lower boost levels on the turbo engine—12 psi compared to 14 psi on the supercharged variant. Power outputs remain uncertain as he hasn’t yet taken it to a dyno.

How Much Did The Turbo 670cc Cost?!?!

At the conclusion of this video, he acknowledges that he could have constructed a more powerful ATV engine for a lower cost. In fact, he could have purchased an entire vehicle with superior power for that sum. However, he aimed to explore the possibilities with the Predator platform, which is easy to install, affordable to maintain, and straightforward to service.

I’m grateful that someone took on the challenge, because I certainly wouldn’t.
