I call BS. The Turbo S runs 10.6-10.8 with awd, launch control 225 more lb-ft of torque and 160 more hp. I seriously doubt that a naturally aspirated S runs 10.9 or better just by adding methanol which isn't even really a power adder. You could put nitromethane in a 991S and maybe get into the 10's.saw a 991S using meth injection few days back running high 10sec.. only mod was ipd plenum
you got to admit thats impressive!
i would've trade my GTS for a GT4, but not having PDK is a deal breaker to me.
Lets assume the power increase is true. I'm skeptical of that. If it did provide the power increase, it might be worth it for street use. For a transplant to a new 3.8L 991S engine, Porsche only offers a $5600 core charge for a near new 325 hp 3.4L engine like mine with only 3900 miles. So it wouldn't bother me to add power, risking my engine, because it's nearly worthless when doing the 3.8L transplant anyway. So if it's increased power and I'm willing to go the 3.8L route, risking my engine might be worth it. .The deal breaker should be risking your engine.
On DFI engines, keeping the valves clean is a good thing. However, water injection will do the same without fear of running out of juice.Meth injection has been around for a while, they started using them on NA engines. I don't see any risk of blowing up a naturally aspirated engine because of meth/alcohol injection. The only risk may come on high boost applications which are specifically tuned for meth, and while going hard on the loud pedal, you run out of meth. BOOM.
Even so, there are now several failsafe mechanisms available which lower the boost and change the timing when running out of meth.
On NA engines, in the right concentration, volume and timing of injection, you can recover lost HP due to heat, reduce pinging and detonation and even keep your valves clean.
Running out of juice is of no real danger if just using it as a "band-aid", instead of having an aggressive tune accounting for meth injection..On DFI engines, keeping the valves clean is a good thing. However, water injection will do the same without fear of running out of juice.
