Quick Tech | Stainless Steel Brake Lines
Saving $10 or $20 on a part or two may not sound like a big deal. However, if you could save an average of $10 on 20 different parts then that adds up to $200. Now, if you could save that $200 on 500,000 occasions, you would save 100 million […]

Engine Tech | Reflash, Piggyback & Stand-Alone ECUs
Twenty-five years ago, “chipping” an OEM ECU for high-performance or racing use left much to be desired. The “piggyback” came to the rescue for some, but others needed to “stand-alone” to unlock the potential of their performance combination. Early stand-alone solutions featured “flying lead” harnesses that required many hours of […]

Engine Tech | Failure Analysis 101
Henry Ford has been credited with saying, “Failure is simply the opportunity to begin again, this time more intelligently.” While we often see people trying and trying again after multiple failures, it’s the “this time more intelligently” portion of the advice that many disregard. Not taking advantage of all the […]

Power Tech | ATI’s 4G63 Damper
Broken oil pump gears, sheared flywheel bolts, loosening clutch cover bolts and damaged bearings are just some of the “fun” that’s in store for your engine if you don’t dampen and control the torsional vibrations in your engine’s crankshaft. The severity and frequency of these vibrations are affected by the […]

Quick Tech | BOOSTane Octane Booster
While Southern California residents enjoy the weather year-round, the search for high-octane fuel is near impossible. The same struggle can be found in numerous other states. Since what you feed your engine determines its ultimate performance, many enthusiasts make the switch to either E85 gasoline-ethanol mixture, or race gas. The […]

Engine Tech | Part 1: Stroker & Nitrous 4AGE Build
The 1980s were challenging times for performance. OEMs were experimenting with the transition to fuel injection from carburetors, as increased emission regulations resulted in systems that choked off performance in a big way. In fact, the 5.7-liter in the 1984 Corvette only produced 205bhp at the flywheel. With its 3,200-pound […]

Engine Tech | DART SHP LS Next Pro : Part 1
An LS engine swap usually provides double or triple the displacement of the four or six-cylinder engine it replaces. All other factors being equal, more displacement translates into more torque and horsepower. While a good number of LS swaps are done with junkyard parts on a budget, choosing the right […]

Engine Tech | O-Ring Measuring and Material
There are numerous small parts on your engine that are always overlooked, and O-rings are definitely on that list. “What can go wrong” is usually the mindset when choosing a small rubber seal; however, choosing the right O-ring for the task is critical. The wrong O-ring could be the cause […]

Engine Tech | G54B Head Development
Simple answers deliver convenience over accuracy. The simple answer to why Mitsubishi’s 4G54B engine struggled to deliver serious performance while its 4G63 engine shined is usually attributed to the number of valves per cylinder. While this answer is convenient, it’s far from accurate. The number of valves per cylinder is […]

Engine Tech | Fuel Octane in Relation to Engine Knock and How to Avoid it
What you feed your engine determines its ultimate performance. The nutritional performance needs of an engine are influenced by a number of factors. Some of these most important factors include an engine’s compression ratio, rpm potential and the boost pressure of the forced-induction system. Engines that run higher compression ratios […]

Engine Tech | Material Hardness Testing
It’s a little-known fact that the “end bug” at the end of every story ever written in DSPORT is the tip of a hardness tester. Specifically, the shape follows the indenter used for Rockwell C testing. We came up with the name Hard Media to describe the audience and goal […]
