Methanol/Alcohol compatible injectors.

[canadian]

I'm looking for an injector that can be used with alcohol/methanol. Checking MSD's website, I see the following information:

"Alcohol Fuels
MSD Competition Fuel Injectors are compatible with alcohol based fuels. When using 100% methanol, the entire fuel system should be flushed with mineral spirits or gasoline to purge the methanol after every race. Any residual methanol will harbor water that will corrode any part that isn't stainless steel.

The internals of MSD injectors will withstand long term use with alcohol fuels, but the external O-rings will swell after prolonged use. Keeping a few spare O-rings (PN 2100) is inexpensive replacement insurance. Remember, that using methanol fuel requires about twice the comparable fuel flow of gasoline. Therefore, double the injector size when determining the correct injector required."

Based on this, their competition injectors are listed at:

Am I correct in that the stock injectors are the "12V Saturated Circuit" while the injectors that requrie ECM modding are the Peak & Hold type?

Fairly sure all the Mototron injectors are methanol tolerant. Depending on your performance goals, you may be able to find high-z injectors to supply the volume you need.
