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.

2021-22 Dodge Challenger Hellcat drops manual option

The six-speed manual has been dropped from the 2022 Dodge Challenger Hellcat at least temporarily while it awaits a powertrain calibration update that will allow it to be sold again, Road & Track reports. The combination has been unavailable to order since November 2021, Stellantis said.  Dodge didn't give R&T much of an explanation regarding the combo's absence, saying only that a revised calibration that would allow the configuration to be sold is coming. When is anybody's guess. In the meantime, we're starting to wonder just how committed Stellantis is to offering its V8s to buyers who aren't opting for half-ton pickups or larger. The inline-six that is slated to replace the 5.7-liter Hemi variant in at least some applications is expected to debut soon. While the 5.7-liter Hemi has surely more than paid for itself at this point, it's likely that Stellantis is limiting availability only to its most profitable models, which help offset the CAFE costs associated with lower fleet mileage. And while Stellantis made quite a bit of noise in recent years about its customers wanting V8s, options for such have become thinner on the ground. The new Grand Cherokee is ostensibly offered with the V8 on its three top trims — Trailhawk, Overland and Summit — but only the last of those can be found anywhere in U.S. inventory with a Hemi under the hood. Trailhawk and Overland V8s simply do not exist. You don't have to take our word for it; you can look for yourself.  Related video: This content is hosted by a third party.

Jeep Cherokee faces on-sale delay

A report in The Wall Street Journal looks at some of the obstacles to the 2014 Jeep Cherokee that go beyond its mootable yet "very contemporary" looks, almost all of them based on Fiat's financial position. Starting with that sheetmetal, in defense of it SRT president Ralph Gilles and Jeep design head Mark Allen said they wanted to "make sure the design still looks modern five years from now."
The WSJ piece doesn't cite longevity as a factor, instead saying that its features originated in a design for an Alfa Romeo, the transformation into a Jeep design meant allowing Chrysler get it to market more quickly and save "hundreds of millions of dollars" in engineering.
The need for Fiat to save money while it weathers the European situation has cut budgets for development, engineering and the pace of retooling the Toledo, Ohio plant to build the Cherokee. In a familiar case of snowballing at work, among the effects will be pushing back the Cherokee's volume sales date and delaying updates to some of Chrysler's other products.
