Showtime Metal Works sure knows their way around a sheet of steel. Building high-quality bumpers, LED-ready grilles, and suspension pieces using thick steel and plasma cutters, these guys go as beefy as they can.
A Cummins engine's internal airflow—and methods of improving it—was the main topic of our recent discussion with Zach Hamilton, maker of the only high-performance, 12-valve cylinder head available for Cummins powerplants.
We recently caught up with Craig Johnson of Big Power Diesel in Palmdale, California, and followed along as he performed a few of these budget-minded upgrades (and some basic repairs) on a 1992 Dodge truck.
When we heard famous EFILive tuner “Idaho” Rob Coddens had a 500-rwhp, LML-powered 2013 GMC Sierra he was playing around with that still had all its emissions hardware intact, we just had to see for ourselves.
S&B Filters just announced it has an intake for 2013-2014 Ram 2500/3500 that incorporates the factory active-air system, while providing excellent filtration and an increase in airflow over the factory version.
Increasing power past factory levels has been absurdly easy since the computer-controlled, common-rail age hit. Still, there are limits to how much you can push the stock parts before they just can’t give anymore.
Nearly three years ago, we set off to build a ’95 Dodge that could do it all: sled pull, drag race, daily drive, and tow. While we were derailed in our performance quest slightly by a badly blown head gasket, we upgraded our head studs and installed fire-rings and were back in business.
It may seem too good to be true, but injecting a mix of water and methanol into a diesel engine can increase horsepower and torque, improve fuel economy, and lower exhaust gas temperature (EGT) and NOx emissions.
