Evan Griffey, freelance writer recently did a piece on the Urbanracer.com website about Vivid Racing’s EVO X and the tuning behind it. Vivid Racing’s long time tuner, Mitch Mckee gave important information on what it takes to tune this beast with the Agency Power GT35R Twin Scroll Turbo Kit.
“The GT35-R is a large frame turbo for a stock 2.0-liter engine,: says Mitch, “so to help try and utilize power faster we opted to go with the twin scroll setup. The twin scroll helps to build boost faster by splitting the turbine housing to optimize exhaust pulses to the turbo more efficiently, as a four cylinder only has one exhaust pulse every 180 degrees. This is one of the perks of the twin scroll on large frame turbo’s is a quick spool time. This turbo achieves full boost by about 47-4800 rpm, which for a 35R is fantastic!”
The Agency Power turbo kit on our EVO X requires many different components including the ECU tuning to maximize its potential. As a kit, this is the only one on the market which is currently making over 650 all wheel horsepower on the EVO X. With the combination of fuel components, upgraded intercooler, and the ECU tuning, Vivid Racing has been able to establish itself as a front runner in the EVO X performance market.
“Some of the big hurdles that we had to tackle were a very limited engine management solution for a car that is so new. We used the ECUtek software and it worked wonderfully but there were some problems from the get go. Fuel was the first big hurdle as from the factory anything over 26 we would max out the system on the stock pump. So to tackle this issue we used a Walbro pump and had to modify the housing to make it fit. Once we had a good fuel pump solution we also had to find injectors that would flow enough to handle the GT35-R, which was our upgrade ‘goal’ turbo. Being how the car was only built this year we did not have a whole lot of options so we elected to send out the stock injectors and had them modified to turn them into 800cc units.”
