How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

2019 Jeep Cherokee base model costs less, but other prices jump

Jeep just recently revealed the revised 2019 Cherokee crossover with a milder nose and tail, and even a bit more cargo space. The redesign has also brought new pricing that presents a $300 discount for the base Latitude trim, but sees increases across most of the rest of the trim lines. The destination charge also increased from $1,095 to $1,195. Four-wheel-drive is now a flat $1,500 increase for all models, whereas it varied between trims on the 2018 model. At the base of the Cherokee lineup is the Latitude, which now gets a price of $25,190, and that $300 reduction from the 2018 model carries over to the four-wheel-drive version. Latitude Plus sees a slight jump in price by $300 for the two-wheel- and four-wheel-drive models, with the two-wheel-drive one starting at $27,690. The Limited trim is up by $680 with both drivetrains, with a base price of $31,570 for one with two-wheel-drive. The biggest price increases come on the Trailhawk and Overland models. The Trailhawk soars $2,425 higher than last year's model, for a base price of $34,515. The Overland two-wheel-drive model also sees a big increase of $2,280 to a starting price of $36,275. But if you want four-wheel-drive in your Overland, the difference is a much more reasonable $535, for a base total of $38,970. View 104 Photos The 2019 Jeep Cherokee will be arriving at dealers soon. In addition to front-wheel-drive and two kinds of four-wheel-drive drivetrains, one with a single gear range and another with low range, a selection of three engines will be available. The standard engine on all Latitude, Latitude Plus, and front-wheel-drive Limited is a naturally aspirated 2.4-liter engine with 180 horsepower and 170 pound-feet of torque. All of those trims can have the optional 3.2-liter naturally aspirated V6 making 271 horsepower and 239 pound-feet of torque. The aforementioned Latitude Plus and Limited trims also have the new turbocharged 2.0-liter four-cylinder available as an option. That engine makes 270 horsepower and 295 pound-feet of torque. The four-wheel-drive Limited, and all Overland and Trailhawk trims have the V6 as a standard engine with the turbo four-cylinder as an option. All engines are coupled to a nine-speed automatic transmission.

Jeep delivers basketful of concepts for the Moab Easter Jeep Safari

It's Easter time, and that means it's time for the 52nd Annual Moab Easter Jeep Safari, held March 24 through April 1, where thousands of off-roaders crawl, scrape and scramble over the rugged trails of Moab, Utah. And that brings us to this year's colorful collection of Jeep concepts, custom-built by FCA for the occasion. Jeep Wagoneer Roadtrip View 7 Photos This year there are seven Easter treats — including one called Wagoneer and one called Jeepster. All are decked out in Mopar parts. (Mopar already has 200-plus parts and counting for the all-new 2018 Jeep Wrangler.) Here then, is this year's Easter pageant of Jeeps: Jeep 4SPEED This year's lightweight concept is meant to bolster off-road performance through extensive weight savings. It's powered by the all-new 2.0-liter turbocharged I-4 engine with an eight-speed automatic. Carbon fiber abounds — the stuff is used for the hood, fender flares and the rear tub, which also features aluminum perforated panels. It gets an "aggressively swept back" look via raked windshield, longer door openings and a custom cage. It's also 22 inches shorter with improved approach and departure angles, though the wheelbase remains unchanged. And it gets Dana 44 front and rear axles with a 4.10 gear ratio and 18-inch lightweight monoblock wheels with 35-inch tires. Inside, there's a custom instrument panel, custom seats and deleted back seats. Footwells are perforated aluminum. The 4SPEED is so much lighter than stock, it rides two inches higher. Jeep Sandstorm This one's inspired by Baja desert racers but can still be used as a daily driver. It gets an extreme-duty suspension system capable of both tasks. The front axle has been moved forward four inches and takes a heavy-duty longarm four-link suspension and track bar. The rear axle has been moved back two inches and gets a triangulated trailing arm four-link suspension. The longer wheelbase provides better high-speed stability. The front wheels — 39.5-inch tires on 17-inch beadlock wheels — get custom coilovers and bypass shocks that allow 14 inches of travel in front and 18 in back. It gets Baja styling cues such as a vented carbon fiber hood, vented high-clearance fender flares and a cage with lay-down spare tire carrier. There are no exterior door handles, and the rear doors have been chopped.
