Another run on the .2 mile
Here is a little info on part of the technical controls for this:
A Blitz Supercharger shipped straight from Japan. eManage ultimate piggyback to intercept the fuel injectors and ignition and map more fuel and timing when it sees boost. I have a MAP sensor and an AFR connected (the AFR has a sensor that I welded a bung in the exhaust for). The emanage also looks at the throttle position and sends an output to turn on the supercharger at 30% depending on RPM and throttle position.
Arduino Nano intercepts the emanage SC signal to police the SC. It controls the supercharger, water-meth pump and a bypass (like a wastegate on a turbo). using inputs from the emanage, a "Mad Max" button in the car, and other sensors like a float in the WM tank and a pressure monitor on the WM line to control whether the SC is allowed to come on. Since I now have the fuel and timing modified for the WMI I have it not allow the supercharger to run if there's an issue with the WMI system. The program is getting too big for the Nano now so I'm upgrading it to a Nano 33 BLE. I'm also doing this upgrade to give me a bluetooth connection to my phone and have an app I configured to be able to monitor and modify settings and timers on the Nano while I'm driving.
The Nano connects to the relay board that uses very low amps from it to control the SC clutch, WMI pump and the wastegate bypass solenoid I installed.
There's also a Greedy boost controller that is set to limit boost to 10 PSI that is mounted in the car. It controls boost using the wastegate once the Nano hands off control to it with a bypass solenoid I installed.
Lot's of other technical but I think I'll just make a new video to go over it all.
As for the WMI pump. It's a standard starter kit from Snow. The pump can push 300 psi but it's governed by the nozzle that's in the intake which is a 175 ml per minute. If you do the math it can use up the tank in 15 minutes at that rate but it does only turn on the pump when I'm using the supercharger and since that's on a clutch and set for 30% throttle it really depends on how I'm driving it for how much it uses. I'm buying winter windshield washer fluid for $2 bucks that has 30% methanol in it and using that for the WMI system so it's not a big expense. Another mod I'm working on is a proportional motor controller that I'll setup to turn down the pump speed at lower RPM.
Please fell free to comment or ask more questions.
