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 defies NHTSA, says it won't recall 2.7M Jeep Grand Cherokee, Liberty models

Facing a possible recall totaling around 2.7 million of its most popular SUVs, Chrysler remains insistent that the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty are safe vehicles. This comes on the heels of a recall request from the National Highway Traffic Safety Administration for these two models due to fuel tanks mounted behind the rear axle, which could possibly be ruptured during severe rear-end collisions, leading to an increased risk of fire. In response to the allegations, Chrysler says that it does not agree with NHTSA nor does it plan on recalling either vehicle.
Chrysler said both SUVs "met and exceeded" the requirements for fuel-system integrity, and cooperated fully with NHTSA since the investigation was opened in 2010. While 15 deaths and 46 injuries have been reported from fires caused by rear-end collisions on these models, Chrysler is claiming that the vast majority of incidents cited by NHTSA were "high-energy crashes," including one where a stopped Grand Cherokee was rear-ended by a tractor trailer going 65 miles per hour.
The automaker wraps up by saying "NHTSA seems to be holding Chrysler Group to a new standard for fuel tank integrity that does not exist now and did not exist when the Jeep vehicles were manufactured." Scroll down for Chrysler's official response to NHTSA, but we're pretty sure this isn't the last we've heard on this issue.

Stellantis tells UK: Change Brexit deal or watch car plants close

LONDON - British car plants will close with the loss of thousands of jobs unless the Brexit deal is swiftly renegotiated, Stellantis has told the UK parliament, the latest in a series of warnings from the industry since the country left the European Union. The world's No. 3 carmaker by sales and owner of 14 brands including Vauxhall, Peugeot, Citroen and Fiat said that under the current deal it would face tariffs when exporting electric vans to Europe from next year, when tougher post-Brexit rules come into force. "If the cost of EV (electric vehicle) manufacturing in the UK becomes uncompetitive and unsustainable, operations will close," Stellantis said in a submission to a House of Commons committee examining the prospects for Britain's EV industry. Stellantis urged the government to reach an agreement with the European Union about extending the current rules on the sourcing of parts until 2027 instead of the planned 2024 change. In response, a government spokesperson said the business secretary had raised the issue with the EU. "Watch this space, because we are very focused on making sure that the UK gets EV and manufacturing capacity," Britain's finance minister Jeremy Hunt said on Wednesday at a British Chambers of Commerce event. The potentially existential problem facing Britain's car industry is closely tied to the shift to EVs. Under the trade deal agreed when Britain left the bloc, 45% of the value of an EV being sold in the European Union must come from Britain or the EU from 2024 to avoid tariffs. The problem is that a battery pack can account for up to half a new EV's cost. Batteries are also heavy and expensive to move long distances. Experts have been warning since Britain left the EU at the end of 2020 that the country would need a number of EV battery gigafactories or potentially lose a hefty chunk of its car industry. Only Japan's Nissan has a small EV battery plant in Sunderland, with a second one on the way. Cost of failure Britishvolt, a startup which received UK government support for an ambitious 3.8 billion pound ($4.80 billion) battery plant at a site in northern England, filed for administration in January after struggling to raise funds. The company was then bought by Australia's Recharge Industries, which has yet to unveil plans for the site.
