The Porsche 991 Turbo comes equipped with 520 horsepower while the Turbo S gets 580 horsepower. It is said that the Turbo S can reach 0-60 in a quick 2.9 seconds. So what do you get for spending about $40K more on the Turbo S? Well you only have a little bit to gain as the turbochargers are tweaked already. At most, you might get up to 620-630 horsepower to the crank. However when you take a stock Turbo, put $15K into it, you are ahead by miles! This particular customer ran his Porsche 991 Turbo at the Wanagofast Event in Georgia equipped with our VR Tuned Tuning Box Kit, Fabspeed Headers and X-Pipe, as well as a IPD plenum and destroyed this 991 Turbo S. As we have tested with our own Project 991 Turbo, the VR Tuned box, Agency Power headers and titanium mufflers, along with our high flow Y-pipe and intakes yields about 630 bhp.
