This turbo would be the perfect match for anyone who is trying to get the most out of a stock motor, have quick response, and have one wicked car. To put everything out on the table, we really feel as though we were maximizing several key components on the car, the motor, and clutch is still 100% stock. The Process West intercooler was getting close to its peak efficiency, the turbo was running at 25Psi, and given the octane of fuel we were getting close to the peak stability point of both fuels that where being used. The amazing thing is just how fast this turbo spools, looking at both race and pump gas you can see that compared to the stock VF48 the increase in lag is quite minimal for the huge gain in performance. Also given the altitude of 4200ft this turbo, compared to sea level it would be able to easily produce over 400WHP at similar conditions due to the increased air density. The power delivery on the vehicle is very smooth and predictable, given the high efficiency TMIC the lag is kept to a minimal and the throttle is very responsive. The vehicle very easy to drive, quick, fun, and overall a simple build utilizing quality bolt on components from proven manufactures ensuring that everything is running at a safe and optimal level.
