I don't know just throwing out ideas. I am going to finish my MR2 and take it for a test drive by Monday. Then it will be on to tuning. Then I will be able to experiment with my own booster.
By the way, how are you measuring you production? I have access to all kinds of measuring devises and was debating a flow meter (yes i know how to compensate the reading to account for the differences in gasses) or using a beaker and stopwatch.
yikes - love your lab. |
I have found that the 4a is sensitive to timing adjustments, when the timing is not spot-on, I know it. I think you will also.
as far as measuring: take a 2 liter bottle, cut off the top, bend a 1/4" copper tube into a U shape, you will connect your booster output to this. Get a 1 liter bottle, measure in 100 ml and mark with a sharpie, keep doing that to the top. Fill the 2 liter bottle with water, invert the 1 liter bottle over the copper tube, when the gas flows in, the 1 liter bottle will raise. I start the stopwatch when it gets to the 100 ml line and stop when it gets to the 300 ml line. You are measuring production, not the individual gases. KISS
Weasy, yes I have thought the time is getting close to get one, but I simply do not have the time right now.
Now for the unexplained results of two recent trips. I have driven this mr2 for many years,,,I know this car. I know that this car gets 27 mpg.
For several months, I have driven 250 miles on a trip that I repeat often. I got 27 mpg. Then I added the booster and got 36 mpg. I have driven the trip many times and the mileage is consistant. Last week, I forgot to turn on the booster. Once I noticed it, I decided to leave it off for this trip. On that trip I got 35.9 mpg. Today, I made the trip again and got 36 mpg without turning on the booster. The booster is still in the car with water sitting in it,,so it is possible that some tiny amount of water is being pulled into the intake,,,but the water cannot possibly be causing this result. But something sure is. I am talking with some knowledgable people about this, so maybe I will have an answer shortly,,,but for now,,,I don't know what to say.
