home made water methanol controller

ok guys need opions im making my own water/meth injection kit for a 85 firebird w/a 2.8 mpfi i am planing on tapping into the cold start solinoid. while using the washer resivor w/a stock fuel pump submerged which will lead to a fuel rail i stole of a honda to regulated volume to the injector. also want to use the tps as a wot switch. i have set up the system on the bench to see spray patern between a few different injectors and the cold start injector give a better atomization. so i am planning to place a t in the steel line with a check valve on the meth kit. i want to get this dialed in for a n2o 100 wet shot thinking about the t-rex system any experince or advise would be helpfull this is the first w/m kit i have installed or put together

If the nitrous kit uses a WOT switch like the old school kits (I'm not familiar with that t-rex system), why not split the feed off of the WOT switch and put a diode in line with it. Reason for the diode is not trip the nitrous system when the cold start injector fires.

the thing is i need the the cold start injecter to fire with the n2o at the same time. what i need to do is put a hi pressure check vale in line to seperate the fuel and w/a system so the cold start will still work for cold starts. and then run a relay in parrelal to activate the injector with the w/a system and n20. the benifits of this combo is estimated around another 25% increase in hp. and be able to keep timing advance and controll pressure spikes as well as the amount of latent heat the alchol with absorb when it evaperates with the water. just water alone takes 1 btu to raise a pound of water 1 degree but when it evaperates it absorbs around 300 or so btus i forget the exact number but im sure you can see the benifits.

When I say use the WOT switch on the N2O kit to fire the meth, what I mean is use it to feed the nitrous system AND the meth system at WOT. This way when the nitrous system is armed and is tripped from going WOT, it will trigger the solenoids for the nitrous and fuel AND the cold start injector for meth. Diodes are 1 way valves for electricity. The reason it would be used in this system is to keep the nitrous system from being run when the cold start injector fires, but will fire the cold start injector (for your meth) at WOT. Ideally you really should have a meth system on its own dedicated injector anyways, but you could use a cold start injector for that as well, but this one would not be hooked to the fuel system. The way you have this drawn in my head would be spraying gas in there as well as the meth when the cold start injector is fired anyways, and you don't need that with a wet system.

that is a good idea about the diode thanks the two systems will be on there own deticated cuircuts. i also want to be able to operate the meth sys with out the nitrous thier will be two switchs one for n2o and one for the meth sys tied to the ground side of the relays. but i will wire the n20 to only operate with the meth sys together a safety thing of course. and the cold start sys has a metal line from the fuel rail to the inj on the back of the manifold so i was thinking if i put a t in the line with a check valve to keep fuel from backing into the meth sys would work but maybe a selinoid would be better i would like this system to be as unnoticable as possible. i will see if i can draw it out and put it up here and i am liking being on this forum the ideas are great

Exactly, but operated with the single WOT switch

ya but as you know their are many ways to skin a mustang or was that a cat or something. lets start with the meth kit first since this will be cheaper and i havent been able to get any sponseships yet no free parts this system will have its own separate cuircut that will have a on off switch in the car wich i am thinking to have controol the ground side of a fuel pump relay. wich will be activated by a wot or tap in a map (yes the car is a maf but i have all these parts any ways also then i wont have to worry about any wierd feed back stuff to the computer mid 80s gm computers werent very solid from my experince) then i can get a better load sensor instead of just a switch then tap into the css and thank you about the diode idea. ok sound good so far ?? now time fuel the flow control. i was planning on taping into the metal linewith a compression t or just use the amf cool braided line looking stuff sorry i can feel my margerita kicking in then have it run through a 80 psi solinoid wich will remain open tell the kit turns on then hit a t block were the meth water will be seperated by a hydrolic one way check valve then be on its way to the css. yes good on we go. before the check valve on the weth line will be a nother solinoid wich will stay closed tell system turns on then the fuel solinoid will close then the magic juice will flow through the check valve and on its way. ok next thought on to the progressive side i was thinking of controling the flow with a honda fuel rail which has a vacum pressure regulater and will also act as a return system to keep the stress of the pump and whala a progresive controlled return meth/water injection system all made with spare parts. so please someone tell me im nuts because this seems a little to easy their has to be something im not seeing.
