S65+methanol injection?

Just like the title says, has anyone tried it?
it raises the octane to 116 any stories behind aswell?
I might be getting it.

meth injection is not good for the engine.

The magnesium and aluminum parts in the fuel system would need to be changed to stainless or something that won't be corroded and you'd need larger injectors and ECU/VANOs adjustments to take advantage of the higher octane & large change in AFR.

Why not just try 100-octane no lead, low ethanol? In California it gives about 30+ more hp.

What are your objectives? Do you want to raise the effective octane or lower the intake air temp?

Typcially methanol is shot in the intake tract just like Nitrous, so why would the fuel components need to be changed?

Its normally used in foced induction applications beacuse it lowers the IATs and lets you run more timing which means more horsepower. Strictly talking Procharged LS1s here.

Thanks for the input guys, I will take that in mind. Actually I was thinking of FI for the future so it will come handy if timing is an issue.

You might want to rethink that. FI is a very expensive journey... Which becomes a fix the domino effect of parts breaking and engines blowing, etc. I'll stop there.

Then get high octane 100% petroleum gasoline. It's readily available in the USA, but I don't know about Taiwan.

Pure Meth is very corrosive, but most use an additive along with it. Water/Meth is a great idea on the S65 with FI. I ran it on my E46 M3, I believe all the AA kits run Water/Alchy, but some run WM. I would run it with any FI kit on this motor.

Methanol is a very corrosive chemical.

That's going to slowly deteriorate all the engine components that come in contact with this chemical over time. (metal or rubber)

It's VERY similar to E85, where you really need special fuel system modifications to accommodate the corrosive nature of that ethyl alcohol/gasoline fuel product.

Every vehicle that is built to run E85 from the factory, has a specially designed stainless steel fuel system. (from the fuel tank & pump, to the fuel injectors & engine) Every rubber seal and metal fitting is rated to handle E85 fuel. (through proper design and engineering)

If these considerations are not accounted for, the OEM materials they touch will slowly succumb to corrosion or accelerated deterioration over time. (due to the subsequent chemical reactions that will take place)

Methanol doesn't play well with others...

Correct.

A properly designed water/meth setup isn't quite as bad, and that also applies to a diluted water/alcohol injection system.

But using a 100% methanol injection setup in an attempt to make more power (as a supplemental fuel source) is a different story. That's where the real damage can occur over prolonged periods.

That setup isn't very good for the engine. (long term)

I hear you Bro, personally I would not use pure meth either.

Another vote here for a water/meth set-up . By adding a good quality water/meth set-up you'll be able to add more timing, lean out AFR's, and possibly run more boost if you changed your pulley.

Also, if you run this set-up you will NOT need to add larger injectors, different fuel pumps, etc. We usually see injector duty cycles drop substantially by adding water/meth.

One piece of advise.....spend the extra money on a good quality system like Aquamist, as it has built in fail safes. If the Aquamist system senses that it is empty or not providing consistent pressure (ie: hard cornering, etc) it will activate a kill switch. On turbocharged cars like GTR's, Evo's, and STI's this system will cut boost immediately. Since a supercharger's boost is controlled by pulley size, rather than an ECU I'm not sure how it would work with your set-up. Perhaps Lemans Blue can chime in here .

Running a water/meth mixture is actually great for FI setup. Injecting water/meth into your charge pipe will remove a great deal of heat as it vaporizes by extracting heat through the latent heat of vaporization. Meth injection kits can effectively clean the valves, valve seats, and piston tops. A water/methanol kit will cool your charge temperatures and transform your pump gas into about 100+ octane fuel. Cooler charge temperatures allow more O2 into your engine allowing you to create more power. Second, cooler charge temperatures assure you that you won't get into the IAT boost decay.
