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.

Jeep Wrangler pickup renderings: Latest imaginings of the Scrambler

The Jeep Wrangler-based JT pickup, which everybody refers to as Scrambler (boy, we're sure going to be surprised if that isn't the real name), doesn't hit the showroom floor until April 2019. That is a long time to wait. What's an impatient nation of Jeep fans to do in the intervening year? Speculate on what it looks like, of course. Jeep Scrambler Forum has sent renderings of the truck our way, shown in the photo gallery above. They depict the Scrambler in two scenes and in four classic colors: Sarge Green, Hella Yella, Sting-Gray and Firecracker Red. The illustrations, we're told, are based on "spy photos, CAD leaks and insider tips we've received." View 7 Photos Like the coming Ford Ranger, the Jeep truck stands to make a huge splash in the hot midsize pickup market, with Fiat-Chrysler CEO Sergio Marchionne saying he expects to see 100,000 Wrangler pickups sold each year. Compare these latest renderings with a set of renderings that ran back in June on JL Wrangler Forums. (We're reprising a gallery of them below, along with a gallery of spy shots.) You'll note some differences between them and the latest renderings, a key one being the seeming absence of that kink (Jeepmeister kink?) where truck cab meets bed. See what other differences you can spot. It'll be a good way to help pass the time until next April.

Jeep Grand Cherokee Trailhawk revived and leaked

We'd love to tell you all about the Jeep Grand Cherokee Trailhawk you see here. Thing is, we don't really know all that much. That's because, according to our colleagues at Jalopnik, it hasn't quite been officially unveiled yet. But that's probably right around the corner, now that the cat is out of the bag. From the leaked images, we can tell that this Grand Cherokee Trailhawk is a lot like the Trailhawk that was produced as a special edition for the 2013 model year. Even the graphics look similar. Expect to see some aggressive tires to go along with all the best off-road goodies Jeep has to offer. Throw in some red tow hooks to match the contrasting interior stitching, mix together some underbody protection, and you've probably got yourself a Trailhawk. We'll have to wait until FCA decides to unleash the official goods to know for sure what we're looking at, but we doubt there's a supercharged V8 underhood. We do know that's coming, hopefully soon, but this isn't it. So, while we patiently wait for that Hellcat-powered Trackhawk to make an appearance outside the realm of spy shots, enjoy the Trailhawk you see here.
