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.

2021 Dodge Durango to get SRT Hellcat limited edition

In January, spy photographers caught what we thought might be a mild hybrid version of the coming Dodge Durango, based on information Mopar Insiders gleaned from the UAW contract with Fiat Chrysler. Turns out we were correct, Mopar Insiders citing info from sources at Fiat Chrysler that the base engine on the 2021 Durango will be a 3.6-liter Pentastar V6 with eTorque. We don't have output figures yet, but he current Durango's base engine is the non-hybrid 3.6-liter Pentastar V6 making 293 hp and 260 pound-feet of torque in SXT trim. The V6 hybrid powertrain is offered in the Ram 1500 making 305 horsepower and 269 pound-feet of torque, and the Jeep Wrangler making 285 hp and 260 lb-ft., but doesn't increase output compared to the non-hybrid engine in either of those models. We're sure buyers would love for Dodge to bump the numbers up into Ram territory, but the eTorque unit serves the god of fuel economy and low-end refinement, so we shouldn't be surprised if there's no change. The MI report says Dodge has three other powertrains coming for 2021. The 5.7-liter Hemi V8 that comes standard on the Durango RT will carry over, adding eTorque as an option. That's the same standard and optional configuration Ram offers on the 1500 equipped with the 5.7-liter Hemi V8. The Durango's V8 produces 360 hp and 390 lb-ft., versus 395 hp and 410 lb-ft in the Ram. On the Ram, the eTorque system improves fuel economy by 2 mpg in the city, 1 mpg on the highway. The 6.4-liter Hemi V8 on the Durango SRT moves into 2021 as well. But the Durango SRT will need to cede its crown to a Durango SRT Hellcat coming next year. Dodge has already put the Hellcat engine in a Durango Pursuit model for law enforcement, making the full 797-hp wrought by the Hellcat Redeye motor. A couple of months ago, Road & Track caught a Hellcat badge on a Durango in a now-removed trailer for the new "Fast & Furious" film, leading all to believe a civilian-use version of the muscle SUV was on the way. MI claims we'll get the Hellcat's 707 hp and 645 lb-ft., but the trim will launch as a limited edition bearing numbered plaques on the instrument panel.  The only bad news in all this is that production shutdowns have delayed the 2021 Durango and the brand new three-row Jeep Grand Cherokee "at least three months from their original launch dates."

The Dodge Demon gets a Drag Mode and a lesson in Newtonian physics

It's Thursday morning, which means we have more news on the upcoming Dodge Demon, the pumped-up Challenger Hellcat variant that's looking to cause mayhem at a drag strip near you. This week's video, "Third Law," shows the Demon's revised suspension in action and displays another one of SRT's cryptic messages. Dodge claims that the 6.2-liter supercharged Hemi V8 in the Hellcat twins is compromised because it's fitted to a car that needs to be comfortable on the street in addition to a performer on the drag strip. Not so with the Demon, as Dodge says the car is "designed to be highly competent in all drive modes and configurations," including the all-new Drag Mode. Dodge says details about the new mode will trickle out over the next few weeks, but all the info this week focused on suspension. The "Third Law" in this week's title refers to Isaac Newton and motion: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body." We're not sure what Newton would have thought seeing the sidewall wrinkling Nitto NT05R drag radials in action, but he'd probably have a reaction of some sort himself. An ideal suspension setup for the drag strip makes for a poor setup on the road. As Dodge puts it, the "old school" way to set up a drag car was to "get the quickest reacting springs upfront, the softest rebound front shocks that wouldn't restrict the springs' reaction, remove any restrictions (sway bar) and increase the compression of the rear shocks." This would give a car great front to rear weight transfer but made for very poor lateral direction control, meaning minor corrections were difficult. The Demon's Drag Mode will use electronics to give the car the best combination of launch and lateral stability. Dodge listed some of the parts to help aid in this goal. They also gave us a few equations that we can't make sense of. Let us know if you have any clues. Hardware: 35 percent lower rate front springs/28 percent lower rate rear springs 75 percent lower rate hollow front sway bar/44 percent lower rate rear sway bar Drag-tuned Bilstein Adaptive Damping Shocks Software: Rear = F/F and Front = F/S F/F – F/S maintained @ wide open throttle (WOT) F/F – F/F < WOT Traction control disabled/ESC maintained Result: 13.5=575@500 Related Video: This content is hosted by a third party.
