Water vs 50/50 (By weight) Water/Methanol
Today I made a street run testing with 100% water injection and 50/50 mixture.
All Injection settings and Boost was kept the same . Starting @ 6psi giving full 300cc Post turbo + 150cc Pre Turbo @ 12psi.
The Results:
- It was noticed that with the 50/50 Mix the Air Temperature was seen colder by an average of 5DegC with some moments giving a 10DegC better efficiency. Since I am probably injecting at 100% Dew point of water, the theory of two liquids mixing better with air gave positive results. Thus the theory actually is true.
- AFR dropped by 1 point when using 50/50 Mixture giving from 13.5AFR on water to 12.5AFR on 50/50.
- EGTs were dropped by 50DegC. Strangely the excess fuel from methanol seems a better coolant than giving the engine 100% water. Presently I am below 700DegC.
Next is a trial run on the drag strip and see what we get on friday.
Cheers
A good luck would be appreciated
