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.

Mopar unveils Dodge Challenger Drag Pak [w/video]

Dodge is going drag racing, and it's doing it with an all-new version of the Challenger for NHRA's Sportsman class. FCA's Mopar parts and performance arm announced the new Challenger Drag Pak Friday, showing off a version with a 354-cubic-inch (that's a 5.8-liter, by the way), supercharged V8 and a 426-ci (7.0-liter), naturally aspirated V8 – both Hemis, of course – that can get the big coupes through the quarter-mile in "the eight-second range." While the two engines deliver similar performance, at their base, they're quite a bit different. The supercharged model uses a cast-iron block, while the 426 has aluminum for both the block and head. That said, both models get customized engine calibrations, and are mated to unique, race-spec automatic transmissions. But drag racing is about far more than just outright power. Mopar significantly updated the four-link rear suspension, adding a four-inch rear axle from Strange Engineering, along with an aluminum, nine-inch third member, while the rear-axle housing has been strengthened in general. Both the rear shocks and front struts can be adjusted for rebound and compression, too. Lightweight 15-inch wheels, meanwhile, are shod in super-sticky Hoosier drag radials, with nine inches of tread in back and 4.5 inches in front. The new Challenger Drag Pak should run the quarter-mile in "the eight-second range." In the cabin, there's an NHRA-spec roll cage, a Racepak gauge cluster, and a handsome pair of Sparco racing seats. Outside, supercharged models get blue decals, while naturally aspirated varieties get black stickers, although there's more to the new Challenger dragster's exterior than just its decals. Mopar tweaked the big-scoop hood, promising it's easier to get up to check on the engine, and the designers also added trailer tie-down straps in both the front and rear. While the dragster was the big news today, Mopar officials also announced the two enhanced Scat Pack kits for both the Dodge Charger and Challenger R/T. The 5.7-liter Hemi models gain an extra 56 horsepower and 30 pound-feet of torque in the Scat Pack 2 thanks to a new cam, valve springs, pushrods, and gaskets. The Scat Pack 3, meanwhile, adds 75 hp and 44 lb-ft, on top of the gains from the lower packages. That should be perfect for drivers who wish to snort in the face of their SRT 392-driving friends. The third stage adds a ported cylinder heads, as well as high-flow manifolds and catalysts.

Driving the Jeep J6, Shakedown Challenger and other Mopar concepts

Mopar has been a one-stop-shop for factory-backed performance modifications and accessories on FCA products for a long time now. You want a 707-horsepower engine for your old Plymouth Belvedere? Mopar has you covered with the Hellcrate. Maybe you want a lift and off-roading lights on that newly-bought Wrangler? Mopar can accommodate those wants (or needs, we don’t judge) as well. We get to see some of the companyÂ’s weirdest creations every now and then, but rarely do we get the opportunity to drive the FCA Mopar concepts. ThatÂ’s what made this past Woodward Dream Cruise so special: We got to rip some of MoparÂ’s finest and most recent creations up and down Woodward Avenue. Everything from a 1971 Challenger restomod to the brand-new Easter Jeep Safari J6 concept was in attendance, so letÂ’s get right to it. Mopar Woodward View 6 Photos 1967 Plymouth Hellvedere This car is near the pinnacle of what you can do with off-the-shelf Mopar purchases. It was only a humble 1967 Plymouth Belvedere before Mopar dropped the 707-horsepower supercharged V8 from the Hellcat into the engine bay. Sound ridiculous? Yeah, it is. Other parts of it are new as well, including the disc brakes. Good call. However, Mopar didnÂ’t remove the classic car charm from the entire driving experience. The steering, for example, is surely as slow and inaccurate as it was back in 1967. That doesnÂ’t help matters when youÂ’re trying to put 707 horsepower to the pavement with less-than-ideal rear rubber. Floor it in damn near any gear of the Tremec six-speed, and the front end rises straight up as the rear kicks sideways with the force of many mules. There are no electronics such as traction control or stability control to step in and wrangle the car into submission. But hey, who wants them, anyway? The question remains: Should you buy a Hellcrate engine for your classic? If money were no object, the easy answer is yes. Have at it so long as you love smoky burnouts and excessive amounts of horsepower. Just make sure you know how to deal with that much power before you stick your right foot in it.   Dodge Challenger Shakedown View 15 Photos 2016 Dodge Shakedown Challenger Concept WeÂ’re going downhill in horsepower with this restomod, but the drivability and ease of driving goes way up. Dodge showed this “Shakedown” concept at SEMA awhile back, and as with most concept cars, getting a chance behind the wheel is a special opportunity.
