2010 Hyundai Genesis Coupe Turbo - Affordable RWD Fun - Tech Talk
Evaluating The Hyundai Genesis Coupe 2.0T With AMS Performance.
By moving the intercooler in front of the rad support, AMS has been able to test a larger
Ivan and the AMS team also measured the factory intercooler, which is just 4.75 inches tall, 3.5 inches thick and 20 inches wide. Given these measurements, clearly this core has a small cross-section, frontal area and volume, which will limit cooling ability and increase pressure drop. According to Ivan, "I don't think it would be out of line to say a better designed core with a larger cross-section, volume and frontal area will increase performance, especially considering the size of the factory core." However, finding the space to mount a bigger intercooler is going to be tricky. "The factory intercooler is sandwiched between the core support and the radiator fan shroud and is just below the radiator. We could get a larger and better-designed core in that spot, but it would be limited. After measuring, we found that we could fit a core that has 44 percent more cross-section, 44 percent more volume and 26 percent more frontal area. Not a bad increase and one that should prove beneficial with the stock turbo or a mildly upgraded turbo. If we moved the intercooler forward and kept the crash beam in place, we could increase volume, cross-section and frontal area by approximately 70 percent. If we remove the crash beam, an intercooler with 160 percent more volume, cross-section and frontal area is possible, which would be ideal for just about any turbo kit you could put on the Gen Coupe."
This all sounds very promising, but moving the intercooler forward so a larger one can be fitted presents a number of challenges. According to Ivan, "The power steering loop (cooler) will probably need to be relocated, as may the horns and two air temp sensors. In addition, the factory intercooler end tanks are support members for the radiator to the core support, so removing the factory intercooler would require brackets be made to keep the radiator in place. The last thing that would need to be addressed is the fan shroud. With the factory intercooler removed, there would be about a 5-inch opening at the bottom of the shroud, which would hurt the efficiency of the fan. To address this, some sort of block-off plate or air guide would be needed."
The 2.0T fuel pump is a nice unit that flows on par with the EVO 9 pump, meaning it won't
With solutions to these challenges well underway, the next obvious step in the pursuit of more power is to turn up the boost. AMS has looked closely at the factory fuel system, ECU and turbo system in order to assess just how easily and reliably boost pressure can be increased. Having already turned up the boost on their Gen Coupe with a manual boost controller, they quickly discovered that the factory ECU limits boost, so AMS' team of ECU geeks are now hard at work investigating various solutions to this problem. With respect to the fuel system, flow testing showed that the stock fuel pump is on par with the EVO 9 pump, so it will not require upgrading until the turbocharger is modified or upsized. Larger injectors will also be needed when upgrading the turbo, and it would also appear that the factory blow-off valve won't tolerate much of an increase in boost pressure, so AMS has already designed a block-off plate for where the factory BOV lives, allowing for a higher performance BOV to be used instead.
