I will do a vid soon but big update for the Twincharged!
I pieced together a DIRECT PORT 50/50 methanol injection kit! I will have 4 nozzles spraying right at each throttle body. I used the following and it was a challenge because of different companies out of different parts.
1. Pro Meth direct port nylon kit with inline distribution block and solenoid. Hopefully this helps someone someday but I went with a solenoid vs a check valve because I am going to use the Motec to control the PWM output to the solenoid and it takes MUCH less current then sending a PWM signal to the pump and trying to run the pump as a progressive kit. Both work but I think the solenoid will be faster response and more accurate for my application. This kit does NOT come with nozzles, pump, filter, or tube, I just like the nozzle holders as they are low profile. $~280
2. Nozzles I wanted Devils Own but their web site stinks and wouldn't take my order then I see they are out of stock. So I went with Snow performance 2.5 GPH nozzles. This will flow enough for around 600hp. Basically if you want 600hp you need 600 cc/min injector, if you do the math converison from 2.5 GPH to cc/min you get around 157 *4 injectors = 628 cc/min. This will take some trial and error here I may need much larger nozzles I am not sure, with the DO kit those nozzles were 370 cc EACH and I know at least one person running that on a RX1 so I either need more or he is injecting way to much water/meth. So I got the Snow Perfomance nozzles (4), pump, filter, tank tap and some 1/4" nylon tubing for $~380. This will be everything I need but a Tank.
3. I am going to add a flow Sensor from AEM this uses a turbine in it to measure actual flow. I can set up tables in my Motec software to respond to this. So if it sees NO flow it will cut all turbo boost out, and I will run on 91 with just the blower and be safe. This will also let me see how much the progressive system is actually pumping. I can also link it to knock and make sure if adds more as a compensation if it sees any knock.
Lastly specific to my sled and the Motec M400 engine management I am out of inputs and outputs so I had to purchase a I/O expander called a Motec E888 which connects via the 2 wire canbus. This will allow me to connect literally anything I want and I can control 8 outputs. I will use up 2 for the meth. Current plan for this expander:
PWM output 1 will turn on meth pump at 12 psi by sending a signal to my PDM which will then power the pump with NO relay. Pretty cool!
PWM output 2 will then send a ground signal to the solenoid at varying rates per my table. I am thinking something like 20% at 15 psi, 50% at 20 psi, 75% at 22 psi and 100% at 25+ psi. What is cool here is I can configure this based on ANY signal in from the Motec. So I can do it by speed, or on a timer, or RPM, etc. I can also set up a knock compensation table to add some if it sees knock no matter what. Motec life rules!
More cool things the E888 allows me to do is it has 8 thermo couple inputs and someday I may add 4 EGTs for each cylinder to keep an eye on problem ones like #3 which like to get hot. I am already adding more fuel to #3 to help cool it so this would be a good validation. I would do it immediately but the Race header from impulse is a FRICKEN bear to get on and off with engine in the sled. I may wait until the engine is out then I can properly install the header and 4 EGTs about 1.5" away from the valves. In the mean time I am going to add 1 post turbo near my O2 sensor to see if my O2 is getting too hot and that is why I can't make them last more than a year. I need the O2 to last so I can run closed loop fuel, right not it's too unreliable and I run open loop. That sensor needs to be reliable so this EGT will help me. In addition once I have a good sensor and good EGT temp correlations I will be able to make a closed loop table that uses BOTH O2 and EGT as a safeguard in case one goes out.
Lastly I am going to get the Motec 5hz GPS module and test if its fast enough and good enough signal in the northwoods to enable some sort of traction control for launching. I am going to turn on my Launch control this year finally and play with acceleration testing. I REALLY wanted to get an accelerometer sensor and use that maximizing G force in the forward direction but they are like $500-1000 and I don't think it will matter on snow. That is just me geeking out on all this newfound data
So upcoming episode will be installing 2nd gate, and laying out my meth and bench testing everything to see that it works the way I want.
Lastly I want to FINALLY try the Ski doo Xp trail tank I got for it and XP seat I have. There is a lot to swap the tank and I will go into detail on that in a separate thread and vid. I have a 2 up seat for the XP tank LOL How funny would that be! More to come!
