So what's the deal with E85? Import enthusiasts often wonder whether E85 is right for their car, and we'd like to present a few points here to help clarify the pros and cons of using E85 in your turbocharged motor. Pros Greater detonation resistance. Ethanol (ethyl alcohol) blends are typically 100+ (RON+MON)/2 (pump octane rating) which allows Peak Cylinder Pressure (PCP) to be placed more optimally safely, which means more power. To elaborate a bit more, part of the reason for the better detonation resistance is that ethanol burns clean and distributes evenly under lower lambda (rich, i.e. < 12 AFR). This leaves less chance...

With seemingly dozens of aftermarket performance fuel injector companies popping up every year, I feel it important to explain why I recommend certain injectors above all others. It's no secret that tuners love Injector Dynamics (ID) injectors, but why is that? Let's take a quick look at the factors most people consider when choosing injectors for their high performance builds.Impedance (High-Z / Low-Z)The starting point for selecting applicable injectors for your vehicle - at least in the past - has always been impedance. There are two categories of injectors that appear in OEM applications: high impedance (saturated) and low impedance...

custom parts, Evo X -

Ryan Reynolds Last night we replaced TJ's puke-filled, top-mount catch can and ETS intake with Driven Fabrication's bottom-mounted oil-separator and air intake system.  For $299 ea. this combo is affordable and well made, coming with all the fittings and plumbing that sits nicely in the X's engine bay.  If you want to take a look, you can find them on DF's website here and here. We started by removing the original catch-can and air intake system. After lifting the vehicle, removing 25lbs of under skirting ( sigh ), we removed the 12mm ground wire and bracket bolts required for the new CC mount. Next,...

calibration, dyno tuning, ECM, ECU, Evo X, road tuning, tuning -

Myth: Road tunes are better than dyno tunes because they more adequately represent real-world conditions.Truth: Most calibration­-grade automotive dynamometers (dynos) provide a mechanism to simulate not only real vehicle weight, but wind resistance as well.At WTF, we use a Mustang Dyno unit capable of absorbing up to 900 horsepower worth of simulated wind resistance and vehicle­-weight­-based inertia thanks to an electromagnetic eddy current power absorber/brake. What this means is that our dyno not only can simulate vehicle weight and aerodynamics, but it can also simulate hills of varying grades and can even hold RPM at a steady state regardless of...
