How Are Your Driving Skills At 100+ Miles Per Hour?

How Are Your Driving Skills At 100+ Miles Per Hour?

It’s cold and absurdly early on this Las Vegas morning, but 30+ people couldn’t be happier. Not just because it’s Vegas, but because East Coast Truck and Trailer Sales is hosting their Richard Petty Driving Experience again. If you’ve never been, the Richard Petty Driving Experience is a thrill ride you control - starting at 100+ mph!

Every year, the folks at ECTTS ask a number of their friends and customers to come out for the driving experience of a lifetime. This is a chance to drive a car as fast as you can – without any fear whatsoever of a ticket. In fact, the faster the better! So much so, we keep track of the stats. 


The day starts with a facility overview of Las Vegas Motor Speedway. There’s roughly 1,500 acres to the Las Vegas Motor Speedway, consisting of over 10 tracks.  There’s the 1/2 mile World of Outlaws dirt track, the quarter mile NHRA drag racing facility known as “The Strip” and the 3/8 mile “Bullring”, which is the home track of NASCAR superstars Kurt and Kyle Busch as well as Brendan Gaughan – just to name a few.

But before you’re allowed to put a 600+ HP car through its paces, you have to go through safety and instruction and in-car/on-track training. This isn’t just a formality if you’re driving these beasts, this is absolutely necessary. You need to know how the brute you’re going to be doing your best to control will handle in a curve, or “out of the groove.” You’ll hear from the instructors/drivers just what you’re going to feel, and at what speed. They know these finely-tuned monsters; they drive them every day.

Now it’s your turn at the wheel; right? Well, first you’ll be taken on a ride-along to get a feel for the track, and experience the car “at speed.” You get to see what it feels like to take a curve as fast as possible without slamming into a wall. Then you get to feel the acceleration push you into the seat – when you’re already doing over 100 mph! You’ll amusedly remember when you used to get a thrill punching the accelerator on the family sedan to pass a sluggish truck. And this is just the instructional phase.


“OK, this should be easy”, you convince yourself, as you climb into the driver’s seat. What you don’t understand – until you try it for yourself, is that the instructor made it look easy because of their experience. For you, getting this race car up to something even close to 130 mph is taking some work. Not that the car won’t do it, but because you’re having a tough time getting up the nerve to go much faster. Way too soon, this thrill ride is over, but you get a chance to see just how much bravado you had. After it’s all over, you get a packet that includes a time sheet with a breakdown of every lap you drove on the track.

Finally, at the end of the day, ECTTS holds a dinner for their customers, friends, and employees. The food’s good, but the stories and laughter are even better. Let’s face it, half the fun of this type of outing is comparing how you did with the rest of the guests. The only problem lies with the inevitable request to see the hard copy of your exploits, to confirm those “enhanced” tales of the track. Chris Kelly, one of our customers, posted this year’s top speed at 141 mph! We’ll keep the lowest speed to ourselves, so as to keep the embarrassment to a minimum.  As we said earlier, we do keep track of the stats.


Keep Your Diesel Particulate Filter From Dying an Early Death

Keep Your Diesel Particulate Filter From Dying an Early Death.

You’re 25 miles out of the truck stop; settling into the long haul, and then the regen warning light comes on - again!You know you just did a parked regeneration to clear the diesel particulate filter yesterday, and you’ve been driving this rig at speed today, so shouldn’t the filter be clean? Well, probably not. Here’s why:

• Unless you’re running a disposable filter system, which are a must in the mining industry and some off-road equipment, the DPF is probably still clogged, but not with soot. The DPF works by trapping soot and other particulates in a network of cells before releasing the smaller gasses through the pores in the filter structure (usually cordierite or silicon carbide). The DPF, like any filter, eventually gets clogged with this material. Unlike other filters, this filter can usually be easily cleared – either while you’re on the road, or parked, by simply heating the filter to the point where the soot burns off to become gasses that pass through the filter. The problem arises when other particles besides soot become trapped in the filter. While hydrocarbons burn, metals and other contaminates from oils in the exhaust don’t burn off at the temperatures used for regeneration, so you end up with a clogged filter – even though you’ve just done yet another regen.

• Why does this happen? The heat from the regen can cause the metal particles to simply fuse into solid masses (sintering), and like the metals, the non-soot particles aren’t going to burn off either. In some cases the filter itself is damaged by the heat being created by the regen. As regeneration happens at temperatures around 850 to 1100 degrees Fahrenheit, and damage happens to some filters at 1200 degrees, the range between clean and damaged can be fairly narrow.

•When the filter becomes clogged with metals and ash; from burning contaminates, it creates high backpressure and triggers a warning on the dash that gets progressively more severe until the truck computer finally throttles back the power – in some cases severely. Filters that become substantially clogged with ash go through what’s called compacting, which can cause filter and engine damage, if not corrected quickly. Overriding the regen causes this compaction. To avoid those consequences, regen every time, on time. Note that the filter will still eventually become clogged with particles other than soot. So what’s the solution? It’s time to have the filter professionally cleaned, as opposed to just clearing the soot.

• Sometimes known as de-ashing, the filter cleaning process begins with an inspection, and then moves through the steps of testing, pneumatic cleaning, thermal regeneration (about 12 hours) and a final air flow test. At the end of the cleaning the air flow test will tell whether it passes for continued use, or needs to be replaced. How often you regen, vs. letting your filter compact with particulates and ash, can greatly affect the usable life of your filter. Similarly, having your filter removed and cleaned regularly increases its lifetime, so this step should be an important part of your regular maintenance schedule.

• Finally, this is not a do-it-yourself job you want to tackle. Unless you have the proper equipment, and knowledge, it will just end up being a very expensive lesson in what not to do yourself. Dealerships and service centers nationwide offer DPF cleaning services; take advantage of it on a regular basis to keep your filter and engine operating at its best.
