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.

2018 Jeep Wrangler production ending to make way for Jeep pickup

After more than a decade in production, the outgoing JK generation Jeep Wrangler is set to end production on April 7. According to Automotive News, parts supplier Hyundai Mobis North America notified the State of Ohio that production was ending. The Toledo, Ohio, plant where the Jeep is built is already deep into production of the replacement JL generation Wrangler. The big news isn't that JK production is ending but that the plant is retooling in order to get Wrangler pickup production underway. Details on the Wrangler pickup are scarce. Jeep hasn't said anything, so most of what we know comes from various spy shots. Basically, expect a JL Wrangler Unlimited with a bed. That's a good thing. We were quite smitten with the Wrangler when we drove it late last year. It's better equipped and more refined than ever. The Toledo plant has a capacity of about 300,000 units a year. FCA CEO Sergio Marchionne expects about 100,000 Wrangler pickups to be sold each year. When the Wrangler pickup arrives, look for a naturally aspirated V6 under the hood. The turbo inline-four is likely, though smaller volumes could limit the truck's engine choices. The upcoming turbo diesel is a possibility, too. Other details include suspension that takes a cue from Ram. Look for a full reveal in the next few months. Related Video: This content is hosted by a third party.

2014 Jeep Cherokee dreams of Moab, crawls on stage [w/video]

The all-new 2014 Jeep Cherokee inched its way onto the stage at the New York Auto Show today, proving that at least the "Trail Rated" version of the SUV is more than just a controversial unique odd fresh face in the mid-size segment. After the short, simulated Moab run by the Trailhawk model, the gray four-door was joined on the stage by a burgundy Limited model - the luxurious highway variant.
As a recap, the all-new 2014 Cherokee rides atop a modular Alfa Romeo-derived platform (we know it from the Dodge Dart) and will be offered in both front- and all-wheel drive models with a choice between a 2.4-liter four-cylinder (rated at 184 horsepower) and a new 3.2-liter Pentastar V6 (developing 271 horsepower) engine. A nine-speed automatic is standard and no less than three different all-wheel drive systems are available.
Of the four different models (Sport, Latitude, Limited, and Trailhawk), we like the rugged looks and capabilities offered by the Trailhawk the best. Overlook the red tow hooks and check out its more aggressive wheel/tire package, flared fenders, reduced breakover angle and lack of brightwork in our gallery of live images from the New York show. Skid plates and off-road capable tires round out the package. Read all the details in the official press release below.
