The windshield washer fluid container on the car is 3 litres. The fuel tank is 22 litres. What kind of boost trigger levels do you think I should set it to if I only want to be filling both tanks at the same time? I'm guessing 10 PSI. I understand it will require some playing around to get right.
The good news is that my mechanic doesn't think post-intercooler installation would be a challenge as much as running the feed from the windshield washer reservoir from the nose to the engine. He has worked with injection systems nominally like yours on gas powered turbo engines about 20 years ago. |
There really are no down sides to alcohol injection with a properly installed system, You can make as much power or as little as you want by nozzle size, set points, and alcohol/water mix.
Remember for the most part your not making moster power over stock your just moving most of your power to a lower rpm so now you have more power at less throttle. even a extra 10% to 20% over stock is not going to hurt your vehicle. Vehicles are designed well beyond what there stock hp/tq is.
Your consumption will be pretty low as you will run a DO1 nozzle for your engine and with a 3L tank it will last depending on set points at least a tank of gas easily.
The big bonus you get is more power at less throttle
Lower EGT
Lower engine operating temps
No heat soak effect
No carbon/soot build up
Reduced emissions
Better kilometers per liter
faster spooling turbo
Better throttle response
Just play with your mixes and set point, You should get a very nice gain even from windshield washer fluid. the -28C stuff will give a nice kick since it's 40% methanol.
