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.

NC dealer creates the convertible Challenger that Dodge won't build

Dodge still hasn't turned the Challenger into a convertible, and the odds of seeing a factory-built drop-top muscle car appear in showrooms are decreasing annually. Tired of waiting, a dealership in North Carolina teamed up with a Florida-based body shop to create a topless alternative to the Ford Mustang and the Chevrolet Camaro. It's the real thing, and it's for sale. Keffer Dodge, Chrysler, Ram and Jeep shipped three 2019 Challengers to a shop named Convertible Builders, according to Motor Authority. After losing their lid, they gained a cloth soft top that opens and closes at the push of a button. There's no word on what effect the conversion has on handling, or what Convertible Builders did to offset the loss of structural rigidity. The build didn't include mechanical modifications. Two of the convertibles are R/T Scat Pack models equipped with a 6.4-liter Hemi V8 engine that serves 485 horsepower and 475 pound-feet of torque. It's not a supercharged Hellcat V8, but it's potent enough to spin the rear wheels in third gear. The third, R/T-based model features a 375-horsepower, 5.7-liter V8. While our dream build would use a six-speed manual transmission, all three come with an eight-speed automatic that sends the engine's power to the rear wheels. Keffer's website lists the gray, white, and red cars at $64,000, $60,000, and $56,300, respectively. The regular R/T Scat Pack Widebody model starts at $46,245, and the eight-speed automatic adds another $1,595, so the convertible conversion adds about $16,000. It's your only option, unless you're brave enough to chop the top yourself, or patient enough to wait until the early 2020s. Dodge has already started developing the next-generation Challenger, so the current car is unlikely to spawn a convertible before it retires. Its replacement due out in 2021 or 2022 will allegedly ride on a wider, longer evolution of the Giorgio platform found under the Alfa Romeo Giulia, among other models, and unverified rumors claim it's being designed with a topless variant in mind from the get-go. It might resurrect the Barracuda nameplate originally assigned to Plymouth when it makes its debut. Auto News Dodge Convertible Performance

1968 Dodge D200 'Lowliner' adds low-down diesel torque to a lowrider

When Mopar does a custom classic car, it's always spectacular, whether it's a Dodge muscle car like the 1,000-horsepower Super Charger or the monster Jeep Five-Quarter off-road pickup. For SEMA this year, Mopar skipped another Dodge sports coupe in favor of a 1968 Dodge D200 pickup truck done up as a lowrider, but with a twist. Or more accurately, with lots of twist. Under the gorgeous candy red metallic body is a 5.9-liter 24-valve Cummins turbodiesel straight-six. It makes an estimated 325 horsepower and 610 pound-feet of torque, and it's paired with a six-speed manual transmission. Representatives from Chrysler estimated the weight of the engine and transmission alone at 1,100 pounds. The diesel engine's power goes to the rear wheels, which are 22 inches in diameter and 11 inches wide with fat 325-mm tires. The front wheels are a tad narrower at 9.5 inches. 1968 Dodge D200 View 7 Photos As cool as the powertrain is, the exterior and the interior of the truck can't be ignored. This generation of Dodge pickup is already intriguing with its distinct character line with a little kink at the end and ribbed and louvered hood. These unique styling cues are accented now that Dodge removed various other details from the body such as the door handles, metallic trim and such. The bumpers were also reshaped to better fit the contours of the body, and the front wheels were pushed forward to reduce the long overhang of the stock truck. The bumpers, grille, and "smoothie" style alloy wheels were also painted in a solid cream color rather than chrome, which both accents the deep red body and gives the truck a more workmanlike feel, as low-trim cars typically had painted trim instead of chrome or stainless steel. The red paint also features subtle Cummins logos on the fenders and Dodge block lettering on the tailgate. The interior continues the simple and classy theme. The original bench seat remains, but with saddle brown leather upholstery. Leather trim has been added throughout, and exposed metal parts have been painted in the same color as the exterior. Simple gray cloth floor mats cover the bottom of the cab, and the instrument panel uses new Mopar gauges in a machine-turned metal housing. The original steering wheel remains, but a custom shifter with red Cummins shift knob sticks through the floor.
