Methanol advice
I know there are many threads regarding methanol installs but none answer the questions i have.
Is running meth possible/recommended with standard downpipes? Can it be run using only a tune, I.e. without jb4 or another piggy? What connections are to be used? Is it easy to install the nozzles after the throttle bodies as I see meth can deteriorate the throttle flaps. Would it be feasible to use meth on a stage 1 openflash tune for example? Would the stock clutches be up for the job with a good tune like openflash flat torque? The big one - Is there any point without serious mods? Thanks |

Your last question is the most important one. Why? Why Meth?
In my personal opinion it is not worth it to install water/meth unless you are looking to go above what a flash tune can already provide. Meaning if you have a flash tune is producing 600whp, there are other tunes out there that can make more up to a certain point. Beyond that point, water/Meth is needed if you want to make more power. That point is 700whp. The stock fuel injectors on the S63tu just can't make any more power than that. But with water/meth you can go beyond that. So unless you are willing to build all supporting mods at the 700whp and beyond, water/meth won't be of much use. Good luck.

G’day
Put in another way water injection only is worth 30-40 whp and there is another op (USA) who built one of the most reliable/powerful s63tu/m5 f10 (he is no longer active on this forum as he’s moved on to the Porsche marque). The current bmw m4 gts has water injection as standard fit (and bmw engineers are looking at all m engines to have water injection for power/pollution/reliability). In my industry (in my fathers era) large multi-cylinder engines had water/meth injection to prevent detonation and to make huge bmep (brake mean effective pressure) = huge hp ! Your Reno aircraft racing fraternity all have water/meth injected engines to beat heat and make huge hp . History is repeating itself as this was technology honed/developed for WWW II fighter aircraft . Cheers Bruce |

There is one benefit which is to help keep the intake, valves, and cylinders clean. You are supposed to get the valves walnut blasted (costly even if not done at dealership) to clean them. Direct injected cars means no detergent is cleaning the back of the valves and our PCVs are still mediocre.
