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.

Junkyard Gem: 1983 AM General postal Jeep DJ-5L

When neither snow nor rain nor gloom of night will stay you from your appointed rounds, you don't need fancy styling or futuristic technology. All you need is a simple steel box with four wheels, one seat (on the right-hand side), a mail-sorting tray, and an engine. The Jeep DJ was that vehicle, and DJs served as workhorses for the United States Postal Service starting in 1955 and — in some rural areas— into our current century. Here's one of the last ones made, found covered with snow in a Denver self-service wrecking yard. Related: Postal truck prototypes spied from Oshkosh and Karsan When American Motors bought Jeep in 1970, it built and sold DJs via its AM General subsidiary. The DJ-5 was a stripped-down, two-wheel-drive version of the pretty-spartan-to-start-with Jeep CJ, and there wasn't much to go wrong with it. The final year for the DJ-5 was 1984. During the AMC era, the DJ received an ever-shifting array of engines, depending on what looked like the best deal in Kenosha at a given time. Starting with the Chevrolet Nova straight-four, Jeep DJ engine compartments boasted AMC straight-sixes of 232- and 258-cubic-inch displacements, followed by Audi 2-liter straight-fours (yes, the same engine used by the Porsche 924), then the 2.5-liter GM Iron Duke four, and finally the 2.5-liter AMC straight-four. This DJ-5L has Duke power. The early DJs had manual transmissions, but all the AM General DJ-5s came with automatics. If you think an Iron Duke powering a Jeep is odd, consider that it's bolted to a Chrysler Torqueflite transmission. Once the USPS was done with them, cheap DJ-5s flooded the market. This one has had a random junkyard seat swap, but retains the handy mail-sorting tray. Featured Gallery Junked 1983 Jeep DJ-5L View 21 Photos Jeep Commercial Vehicles Classics amc mail truck

Fiat Chrysler to get $105M fine from NHTSA for recall woes

The National Highway Traffic Safety Administration is about to send a powerful message to automakers doing business in the United States, assuming reports of an upcoming $105 million fine against Fiat Chrysler Automobiles comes to fruition. In addition to the record-setting monetary fine, according to The Wall Street Journal, FCA will have to accept an independent auditor that will monitor the company's recall and safety processes and will be forced to buy back certain recalled vehicles. In other cases, such as with Jeep Grand Cherokee and Liberty models with gas tanks that could potentially catch fire in certain types of accidents, FCA will offer financial encouragement for owners to get their recall work done or to trade those older vehicles in on new cars, according to the report. FCA could reportedly reduce its fines if it meets certain conditions, though those remain unclear at this time. These actions against FCA are being taken after NHTSA began a probe into the automaker over almost two dozen separate instances where the government claims FCA failed to follow proper procedures for recalls and safety defects. Included in those safety lapses are more than 11 million vehicles currently in customer hands. These penalties and fines are separate from the investigation over security problems with Chrysler's Uconnect system that allowed hackers to obtain remote access into key vehicle systems in 1.4 million vehicles.
