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.

Chrysler recalls 350k vehicles over ignition switches

Chrysler has announced a recall covering 349,442 vehicles due to ignition switches that can either become stuck or move without warning. All of the affected vehicles are from the 2008 model year, and were built before May 12, 2008.
The automaker has learned that ignition keys on some vehicles "may not fully return to the 'ON' position after rotation to the 'START' position during engine-startup," the company said in a statement. Additionally, "an ignition key may not fully return to the 'ON' position after rotation to the 'START' position and may inadvertently move through the 'ON' position to 'ACCESSORY' or 'OFF.'"
Chrysler says it is unaware of any related injuries, and notes that while reduced braking, engine or steering power is possible in such instances, the airbags are not affected. The later stands in contrast to General Motors' recent rash of high-profile recalls, and it's an important distinction that Chrysler (understandably) felt necessary to call out in bold print in its press release.

Jeep Wrangler-based Scrambler pickup will have open tops, longer frame

We'll probably have to wait until 2019 to see the Wrangler pickup fully revealed and on dealer lots, but it seems that the truck is already showing up in FCA's computer systems. Someone at Jeep Scrambler Forum did a little digging and found the truck's chassis code, "JT," listed with a number of parts. Among those parts were different tops, seemingly confirming that the Wrangler pickup will have a soft folding top and removable hardtops available, just like a normal Wrangler. These include the plain black soft top, a black hard top, or a body-color hard top. The hard tops are also listed as three-piece units like on a conventional Wrangler, so parts can be removed, or the entire top. The forum quotes sources as saying the pickup will be called the Jeep Scrambler. The company renewed the trademark on that model name in 2015. The forum discovered a few other mechanical details, too. The truck's code is listed under the diesel engine option, confirming that powertrain for the pickup, though no other engine or transmission info was found. The forum also found CAD models of the frame and axles. Jeep Scrambler Forum estimates the frame is about 33 inches longer than the upcoming Wrangler Unlimited four-door SUV. This isn't entirely surprising, as photos show that the Wrangler pickup prototypes are substantially longer than the four-door Unlimited models. And even AEV had to lengthen the Wrangler's frame to turn it into the Brute pickup. Finally, the forum noted that the axles are different from the current generation of Wrangler, and could possibly be stronger than normal for improved towing and payload.
