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.

SpeedKore carbon-fiber 1970 Dodge Charger packs a 996-hp Demon engine

SpeedKore Performance does some pretty neat things with carbon fiber. SEMA is always the place to show off new and interesting builds, and SpeedKore has a few new offerings on display. We talked about the lightweight carbon fiber 2018 Dodge Demon late last week, but now that SEMA 2018 is in full swing, we've got a look at something even cooler, an all-carbon, Demon-powered 1970 Dodge Charger "Evolution." SpeedKore Performance is based in Wisconsin and has been churning out SEMA showstoppers for years. In addition to the Demon, take a look at this Shelby GT350R the shop modified a few years back. The Charger Evolution is named so because it further modifies the SpeedKore Charger "Tantrum" that was used in the " Fast and Furious" films. That car used a carbon composite body and was fitted with a 9.0-liter Mercury Racing twin-turbo engine making an absurd 1,650 horsepower. The Evolution might be down on power — only 996 horses thanks to a modified Demon crate engine — but the goal was to create something a little more usable than the Tantrum. Upgrades include a smaller supercharger pulley, larger fuel injectors, a custom cold-air intake, stainless steel headers and a custom exhaust with SLP mufflers. There's also a Dailey Engineering dry sump, upgraded oil cooler, and Saldana radiator. It's also lighter, thanks to even more carbon fiber. SpeedKore had a goal to get the '70 Charger to about 3,200 pounds. To get there, the Evolution employs carbon-fiber bodywork, an aluminum floor, a steel roll cage and a new 2x3-inch steel box frame. SpeedKore's autoclave is large enough to bake a one-piece roof, hood and quarter panels. The bare bodywork has been finished with a clear coat to help prevent fading. The Evolution uses billet aluminum for the door handles, fuel cap and grille, all finished in a bronze-nickel coating to pair with the HRE wheels. In addition to the floor, aluminum was used for the firewall, transmission tunnel and radiator shroud. To slow the Charger down, it uses Brembo brakes with six-piston calipers up front and four-piston calipers in the rear. The suspension uses Penske adjustable coilovers while Michelin Pilot Sport 2 tires wrap 19x10-inch front wheels and 20x12-inch rear wheels. Related Video: This content is hosted by a third party.

Stellantis axed the SRT engineer team, but performance isn't going away

Stellantis has broken up the Street & Racing Technology (SRT) engineering team that created over a dozen high-performance vehicles, including the Dodge Charger Hellcat, but the situation isn't as dire as it sounds. The newly-formed company assigned SRT's former engineers to different positions, where they'll continue to make hot rods. "All of the core elements of the SRT performance engineering team have been integrated into our company's global engineering organization," a spokeswoman told enthusiast website Mopar Insiders. She added that integrating SRT's personnel into other brands in the Stellantis portfolio will ensure that the lessons learned from decades of peddling speed will permeate other products. Previously, SRT operated with a high degree of independence. Don't get too excited. Her statement does not necessarily mean that Citroen will begin building cars powered by the Hellcat engine, though a C3 Chat D'enfer sounds absolutely epic. Technology transfer will likely be limited to fields like aerodynamics and thermal management, and the design department might learn a couple of neat new tricks. Dodge will still move forward with the development of its next SRT-branded cars; the decision to dissolve the SRT team will not affect future models, according to the spokeswoman. Whether they'll be powered by a V8 is up in the air, because company boss Tim Kuniskis warned that regulations are killing the eight-cylinder engine. Similarly, Jeep will continue designing high-performance models, like the Grand Cherokee Trackhawk. What changes is that the model will be developed and designed by a group of engineers and designers from Jeep, not from SRT. SRT is dead, but performance isn't going away. SRT's demise nonetheless marks the end of an era for Chrysler. The division traces its roots to 1989, when some of the company's brightest minds were brought together to develop the first-generation Dodge Viper. It merged with Team Prowler to form the Specialty Vehicle Engineering (SVE) group, which was renamed Performance Vehicle Operations (PVO) in 2002 and finally dubbed SRT in 2004. SRT has operated as the carmaker's in-house tuner since, its resume includes a diverse selection of cars ranging from the Neon SRT-4 to the 1500 TRX, and it was promoted to a standalone brand led by designer Ralph Gilles in 2011. Fiat-Chrysler Automobiles (FCA) axed the SRT brand in 2014 but kept the name and the development team. Related video:
