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.

Watch Atieva's electric van outrun a BMW i8 and Dodge Viper

A little while back, automotive startup Atieva drag raced its electric van, called Edna, against a Tesla Model S and a Ferrari California in order to compare its performance against known and revered mechanical athletes. Again, the Silicon Valley-based company is putting its prototype up against electrified and conventionally powered performance vehicles on the drag strip. Last time around, Edna, the Mercedes-Benz Vito van equipped with a 900-horsepower, all-wheel-drive powertrain, bested both of its foes. In that showcase, Edna was hitting 60 mph in a little over three seconds. Comparatively, BMW lists the i8's 0-60 time at 4.2 seconds, though Road & Track clocked it at 3.8 seconds, with a quarter-mile time of 12.3 seconds. The Viper does 0-60 in 3.4 seconds. Before you even watch the video above, you can imagine how it will end, as the retuned Atieva Edna rips 0-60 mph in 2.94 seconds. Atieva clocked the quarter mile at 11.3 seconds at 117 mph. It's worth noting that driver skill can have a lot to do with a car's straight-line performance. We've witnessed Viper's elapsing the quarter mile in well under 12 seconds, which means it should be quicker in this test than the i8, if not the Edna. Still, the performance showcased in the video is exceptional. To improve Edna's stats, Atieva says it has used testing data to fine tune its AC induction motors at higher speeds once it got low-speed performance locked in. After testing in the hot California sun, including the race you see above, Atieva drove Edna 90 miles home with range to spare. As for production plans, Atieva will put this powertrain into a sedan slated for sale in 2018. In the meantime, the company will keep testing and tuning its working prototype, and has even invited the public to put their cars up against Edna in future sessions.

Dodge Grand Caravan reportedly will cease production in 2020

The Dodge Grand Caravan looks like it may finally be reaching its demise next year. A report from Automotive News Canada says the old Dodge minivan will cease production in May 2020. The report cites AutoForecast Solutions as the source of its news. FCA confirmed to us that the van will be going away eventually, but the company is not ready to put an official end date on it yet. For the time being, it looks like the Grand Caravan’s long run will eventually grind to a halt in Windsor, Ontario, the vanÂ’s only production site. With the introduction of the Chrysler Voyager as the budget minivan option from Chrysler, FCA may think it no longer has any use for the outdated Dodge. The Grand Caravan has a starting price of $28,535, whereas the new Voyager is priced from $28,480. ThatÂ’s an almost identical starting point, but we still donÂ’t know what kind of incentives FCA will offer for the Voyager. There are typically big cuts for the Grand Caravan, which have pushed recent average transaction prices down to $24,972. We imagine itÂ’ll be much more difficult for FCA to offer discounts of that magnitude to Voyager shoppers. Still, AutoForecast Solutions told Automotive News it believes FCA will transition folks away from the Grand Caravan. “For the 2020 model year, theyÂ’ll likely run to fleet and then get the consumers to buy the new Voyager,” says Sam Fiorani, vice president of global vehicle forecasting at AutoForecast Solutions. Eliminating the Grand Caravan would be a strong bet on ChryslerÂ’s strategy of splitting the Pacifica into two different model lines. Nearly every month, FCA sells more Grand Caravans than Pacificas. The Pacifica is the far superior minivan to own, but you canÂ’t argue with a cheap price. Once the Grand Caravan is gone, budget minivan buyers will have no choice but to buy a Voyager if they want the cheapest new option out there. Entries from the few other manufacturers that produce minivans are all going to be more expensive than the Voyager. The 2020 Pacifica and Voyager team are slated to reach dealers later this year, but it wonÂ’t be until next year that weÂ’re able to fully take stock of how this plays out for FCA.
