86 THE SHOP NOVEMBER 2018 Turbocharged STS Turbo's Smith notes that when it comes to turbos, bigger isn't always better. "Many times, a customer has a certain power level they are looking for and shops may look at the largest turbo to reach that power level. The problem with a large turbo is turbo lag and power output that is lazy down under the curve." And Garrett's Coltey has a list of issues shops should watch for. "The top mistake is turbo-matching, meaning over-sizing or under-sizing the turbo to the engine, which can cause too much lag if the turbo is too large and adversely over-speeding if it's too small," he says. Next is not using an oil restrictor on ball bearing turbochargers. "Ball bearings do not need as much oil lubrication as a journal bearing and can cause oil to leak from the seals if the pres- sure is too high," he explains. And a third issue is not water-cooling the center housing. "Water cooling is a design feature in the center housing that reduces the occurrence of oil cooking," he explains. "After shutting down the engine, heat from the turbine housing and exhaust manifold tends to absorb back into the surrounding com- ponents. During normal engine operation the water pump flows water through the housing to provide a cooling effect. When the engine is off the pump is no longer flowing water. However, if properly set up, thermal siphoning will occur and pull water through the center housing to absorb heat, which then rises through the cooling system and pulls cooler water through the turbo." SALES TIPS Thoroughly understanding design features, benefits and applications will help shops increase turbocharger sales, the suppliers report. "When dealing with performance tur- bocharger applications, shops with strong product knowledge will have the highest levels of customer satisfaction—before and after the sale," Harcourt says, noting that BorgWarner is among the turbocharger manufacturers that offer an online turbo- charger matching tool. Installation versatility is also a plus. "With our systems, the ability to mount remotely or at the rear of the vehicle is valuable to a shop, since no emissions equipment is affected," Smith says. "Also, there are no increased engine compart- ment temperatures, so no melted wiring or hoses, which really cuts down on any installation warranty issues. There's also increased reliability, since there are never any blower belts to replace." Asking for help is never a bad thing, especially for shops still learning the ropes. "Turbocharging a vehicle can seem quite complicated, and it is until you get the hang of it," Coltey reveals. Garrett is among the turbo makers with a wide dis- tribution network that can help installers through the process. Finally, Kimpel's advice for making money in the turbocharger market is straightforward—specialize. "It's easy to get caught up in the internet sales trends these days, but setting yourself apart from your competition is best," he argues. "Marketing yourself in your area of expertise always helps set a business apart from the next. Turbochargers are no excep- tion. Market the product to your audience, and make sure to use modern techniques such as social media." There are turbochargers available that fit anyone's power requirements and budget.
