Knowledge is power is an often-used phrase, but real data from a computer with no ego can give you the good, bad, and sometimes ugly details of your last time around the track. Track data loggers were once something only professional racers could afford, but thanks to the aftermarket you can get pro-level data at a weekend warrior price point.
Racepak sent us one of their new Vantage CL1 track data loggers to play with, and we loved being able to see what we did right and wrong at the track. Since then, Racepak has come out with the even more affordable CL2 OBDII based data logger. Either way you go, this technology can make you faster at the autocross, road course, and even dragstrip. So let’s take a look at how this 21st century tech shakes out.
01 Here’s what comes in the box from Racepak: the CL1 data box, RPM harness, USB charging cable, charging cable to CL1 adapter, magnetic GPS antenna, OBDII cable, and four rechargeable AA batteries. There are options, but for most people this will get you up and running.
02 The heart of the system is the CL1 data box. It has 10 user-defined OBDII/EFI inputs along with eight total external sensor inputs through four connectors. Four of the user-programmable inputs are analog, and four are digital. There’s also a CAN input for future expansion. It connects to your device via Bluetooth, and there’s a plug for the magnetic GPS antenna. The box is small at 3x3 inches and weighs half a pound. The CL1 comes with three isolating feet if you want to do a more secure mounting.
03 You can mount the CL1 wherever you want, so long as the wire is long enough for the GPS antenna to get to where it needs to go. Make sure the CL1 is someplace where you can reach the controls and see the status lights, but keep it away from high heat or excessive noise generators such as MSD ignition boxes.

Is It Better to Change Oil Hot or Cold?
It seems intuitive that if time is not a factor, the most thorough way to change engine oil is by letting the car sit overnight, then next morning allowing the oil to drain out of the sump for several hours.

California Coastal Road Trip
Like many people around the country, we have had little occasion to travel this year. With car shows and events like the Power Tour and Drag Week postponed and rescheduled due to the coronavirus, we’ve mostly been stuck at home. I recently had occasion to travel to Santa Rosa, California, for a photo shoot with Scott Birdsall, owner/builder of Old Smokey, the Cummins-powered Ford F1 that beat the diesel-engine record at the Pikes Peak International Hillclimb. Motor Trend’s William Walker was the shooter, with me serving as assistant and camera car driver. It seemed like as good excuse as any to make a trip out of it.
25 Years of the Crusher Camaro
I’m gonna tell the story of the Crusher Camaro because it’s celebrating 25 years as a project and because it’s presented me with a fresh dilemma. The story begins in 1994 when California law allowed gasoline companies to crush older cars in exchange for smog credits that allowed continued polluting from wells and refineries.
What Is Cylinder Head Swirl and Tumble, and Why Is It Important?
We think of electronic engine management systems and multiport electronic fuel injection (EFI) as primarily responsible for the improved air/fuel distribution and performance as Detroit clawed its way back in the mid 1980s, but—good as they were for that day—initially the new electronics were just Band-Aids grafted onto carryover engine designs. The big change started in the 1990s, when the OEs started tinkering with cylinder head design to induce swirl and tumble in internal combustion engines.
