We decided to bring to market the best check valve possible. We did not just have an existing check valve and have the crack pressure raised like others. This is 100% custom made, and Installation does not require the use of adaptors. This check valve features a 2 piece design, so its field serviceable. This check valve has a 16 PSI cracking pressure. We found any higher would reduce the function of the system. This means it?s not possible to open during engine vacuum and holds pressure in the line, while not reducing flow with a higher check. It also features a electroless Nickel plating over brass, so it should stay shiny silver and not look like you hit the hardware store up under you hood. Notice the push to connect built in? These are almost 10 dollars cheaper than others when you consider you need fittings to hook it up...
Check Valve attached to our nozzle holder
Notice the specs on the fill @ 90psi. This Can't be touched by others check valve. This is a very fast acting check valve.
Solid Model of our check valve.

i got it all installed today and it ran fine while injecting so i guess we will just see the results tomorrow.
easy kit to install, my only pet peeve was the tiny screws on the controller that had to be inserted, the wires were a little fat so i had to cut a couple of strands off the wire to get it to fit properly. i also ran into an issue, i thought the FC3S pressure sensor would work but after about an hour of trying to wire the sensor various ways it was a lost cause since the signal is also modified by the AFM and BARO sensor so i borrowed an FD3S map sensor and it worked fine after that.

i ran a 50/50 mix of pure methanol with distilled water, for pure methanol you would need a fuel cell to run it safely since it is flammable in the engine bay 100% methanol in a washer bottle wouldn't be very safe.
i ran it up to 18psi without any detonation issues as i had previously so it is doing it's job just fine. i didn't take the boost higher because A) it appears the hybrid ran out of steam earlier than i hoped and B) my LT8x is only setup for 2bar atm and not sure what it does past 20PSI since that is the end of the maps for the 2 bar model. for now i am just going to play with the timing and split to see the differences with the methanol kit in, i ran out of time on the dyno and wanted to do a few more things before continuing with the tuning.
in all honesty i wasn't thinking when i ordered the kit and thought it came with a map sensor and if it didn't i figured the FC map sensor would work but unfortunately it won't unless you have a factory ECU wired up. the FD map sensor works just fine.

Brian didn't build it, a guy in LA built it with a Garret compressor wheel with stock hot side.
it made 271 to the wheels at 10PSI but i didn't get a chance to start playing with the timing much. at 18PSI there was no noticable increase in HP, just a little added TQ so for now i am just running it at about 12PSI and playing with the timing but not going far until i have a EGT gauge installed.
things i have noticed before and after the install is with the added timing in lower boost levels the turbo spools faster and pulls harder in the lower RPM range.
after finding out this turbo can barely push 12PSI efficiently it is going to be ditched and i am going to try and find a BB T40 or something similar to throw on it so it can push up to and past 20PSI once i have the standalone reconfigured to support the higher boost levels.
i have been daily driving the car and it probably has about 3000 miles on the AI and i have had no issues with it whatsoever, i will need to get a bigger reservoir though, the .5 gallon bottle i have now is just a pain to keep full.
i will probably dyno the car one last time with this turbo after i get the timing fine tuned to see where it's at but i was rather disappointed to find out the trim of the compressor wheel had such a low output. even at 10PSI i can't keep traction with the 285's i have in the back but for the long term i want a car capeable of 11's, not low to mid 12's and the problem is just with the turbo not the AI.

i placed the nozzle in the elbow before the throttle body, about 4" upstream so it can be dispersed to all intake runners evenly.
wish i could say the nozzle size, i don't know.. i put my trust in DO on that one and i didn't even think to look at the number stamp on the nozzle before installing it but i would guess it is either an M6 or M7 nozzle. (i will check it when i replace the elbow, it is leaking so i need to replace it with a more solid one)
i will try and get some pics when i have the time, been rather busy lately with the holidays but it is a simple setup: i have the reservoir right behind the front bumper support just under my air deflector shield in the engine bay so it is easy to get to and refill. i located the pump down on the inside of the drivers frame rail, well below the level of the bottle to keep the system primed as suggested and lastly the nozzle is before the throttle body in the elbow. simple and easy setup.

yes, gravity helps keep the pump filled at all times. i have my tune set up with the AI so if it pumps air for even a small amount of time and has built enough boost by then, well, bye bye engine.
i don't see why you couldn't run it on a stock ECU/turbo setup. if you think about it the methanol is a fuel so even with a piggyback it is still increasing the support of the fuel system, in total i would guess it is adding about 10% or more to the capacity of your fuel system depending on your nozzle size, controller settings and what mixture of methanol you run. you would need a piggyback though to remove or add fuel for adjustments sake or it will wind up being too rich or too lean at certain points depending on how far you push the turbo and what other fuel mods you have going on.
there really is no drawbacks to adding an AI system, you just have to have the capability to tune around it.
if you run an SAFC as a piggback though i would STRONGLY suggest you hook it up to the boost sensor not the TPS though.

FWIW DSM guys said they saw almost a full point richer AFR under full meth inj. in certain parts of the rpm range. I want to run meth but I am waiting for the tuning tools first
