2nd set of methanol compatible fuel injectors further up the intake runner or pre turbo fed by a methanol compatible fuel pump with a pressure regulater and return line into a small fuel cell, say 10l. Essentially a second fuel system. This way you get all the flow you want with the control you want. This has been done before and it works great.

WHEN SPRAYING LOTS OF METH, SOME DISTANCE IS NEEDED TO LET EVAPORATION AND AIR MIXING TO HAPPEN EFFICIENTLY. STILL THINKING OF THE POSITIONS...

I THOUGHT OF A SYSTEM LIKE YOU DESCRIBED BUT THERE ARE TWO PROBLEMS.

1. COST

4 NOZZLES + 4 PUMPS + TANK IS LESS EXPENSIVE THAN 4 METHANOL INJECTORS + REGULATOR + METHANOL PUMP + TANK

2. CONTROL/EFFICIENCY

THE INTENTION IS TO USE A MAP ACTIVATED BY PWM DUTY RPM VS BOOST TO CONTROL FLOW. HALTECH SPORT 1000 ECU IS NOT CAPABLE TO CONTROL A 2ND INDEPENDENT SET OF INJECTORS.

Use your current water injection system to spray any water you need or want on top of that. As flow requeirements are now much reduced, use your current system as is. You may add 15% methanol to the water tank to keep it sterile.

THE REAL PROBLEM IS SINCE THE CAR IS STREET DRIVEN I NEED TO TAKE PRECAUTION FOR MIXTURES ABOVE 50/50. METHANOL AT SUMMER TEMPS IN THE TRUNK WILL BE DANGEROUS

There is no need to inject methanol and water at once as a mix. It has its merits, but I would not try to build a classic water injection system with membrane pumps to provide the entire fueling of a car. There are suitable and reliable pumps,fuel lines, connectors, fuel pressure regulators and injectors on the market for just that. Fuel injectors will also give you the precise metering capability out need for the same money as 4 water/meth valves and jets. They are plug and play to any ECU with 2nd injector bank capability such as the Emerald K3 I am using. Hondata will likely support this as well.

AS SAID ABOVE ... ADDING THAT METHANOL LIKES IT RICH. NO MATTER HOW MUCH YOU INJECT THE BETTER IS ABOVE STOICH. NO NEED FOR PRECISE METERING.

Besides methanol those pumps, injectors etc. would also be E85 compatible if you shall have the desire to try it. It is more stable than pure methanol and available at petrol stations. You could also run a mix of e85 and methanol. You gain flexibility.

E85 IS NOT PRESENT IN OUR COUNTRY AT PETROL STATIONS. YOU NEED TO BUY DIRECTLY FROM RACING FUEL COMPANY JUST LIKE METHANOL. ALSO E85 OR ETHANOL IS MORE EXPENSIVE AND LESS POWERFUL THAN METHANOL. WHY WOULD I USE IT THEN?

THE ONLY DISADVANTAGE OF METHANOL IS FUEL CONSUMPTION.

Run petrol off boost and it automatically switches to e85/methanol, 100% ethanol etc. as you wish. Water comes on top of this from the system you already have. If you go that far, do it right.

YES THAT IS THE PLAN... I WOULD APPRECIATE ANY PRECAUTIONS
