Ok so i have a devils own progressive cobalt/ion meth kit. the pump is working the controller is working however, my issue is this:

it pulls methanol/water under vacuum like at idle mainly..... WHY??????

its trunk mounted.

/help!

 

Ah that sucks. Your check valve is probably messed up which is why the guy sold it in the first place. OTT sells them. That would be my guess. Maybe some other guys can chime in.

 

idk the guy i bought it from is a respectable poster here. he did say that everything was working when he sold it to me, said he took it off when it was time to ship it to me....

the check valve i read is only for one way free flow so basically the air cant get into the tube once its primed, but may freely leak the other way.

there is a selenoid that stops flow either way to prevent siphoning but i dont see why i would need that if others with the same kit do not have it.

yes others please chime in

 

Is you meth line after the throttlebody? If so you need that solenoid or a better check valve.

I sold a meth kit on here and when I took it off my car it was working fine.. Got to the guy and it was spraying under vaccuum for some reason.. I'm unsure..

 

meth line is tapped after the throttlebody. in a spacer

so a selenoid will deffinitely fix the issue or should i try my luck for 15 dollars less and buy a new check valve.... moreover do i need both?

 

Check valve.

 

alright 1 vote for just a check valve... any one else im gonna buy this here in a few minutes.

 

Actually thats 2 votes.. I also said check valve.

 

alrighty, well i actually just read some where on a way to fix the check valve is its behaving this way. ill try that tonight and if no dice then ill purchase it tonight or tomorrow and i should have it b4 the meet.

 

Good Luck. You'll love the car when its tuned for it.. Now ya just need a H/DP :P

 

The issue is where you have it tapped. Behind the TB will cause it to draw past the spring pressure. You need to get a stronger check valve or put the check valve right next to the tap with a real short piece of tubing.

 

Get a electric solinoid valve. I hookd it up to the power on my pump and when the pump turns on it opens no power closed....no problems....

 

well i have mine after the tb i just did meth jet 90elbow than check valve and i dont have no problems

 

My check valve is attached to the 90* elbow that houses my nozzle

because of this post im having mixed emotions now.... how many others have had this problem... i cant be the first.

may i reitterate that i do really appreciate the help that everyone is providing me.

and where on your line do you have the selenoid?

 

devils own check valves are crap. mine and my friend's both work when they feel like it. sometimes they wont close, sometimes they wont open.

 

perhaps you could have installed it backwards????

 

ok cleaned the check valve and stretched the spring.... ALL GOOD

no i didnt install it backwards!

i can deal with it not closing ..... but not openning is the scarry part. what wou toy suggest for a better check valve?

 

I bought a better check valve from coolingmist.com when my Devil's Own was literally fell apart. The solenoid option worked for a short period of time, but also got screwed up. The coolingmist unit is one stout part and worked flawlessly for me.

 

good to know, thanks!

 

No problem. I have a lot of experience with the Devil's Own kit and the AIS kit as well so if you have any more questions please feel free.

 

Little ways down from the pump...My pump is located where you put the Option B tank and the solinoid is right in front of my dip stick for engine oil then it goes to a T fitting (1 inlet , 2 oulet) then the RAW Meth plate with 2 nozzles after the blower....

 

What do you guys think of the quality of the Devils own kit? Like if OTTP sells it I assume its great quality. You say the check valves are crap? Can you purchase better ones from them or someone else? I am new to the whole meth injection and I am looking into purchasing the Devils own kit but I want to make sure Im not buying a shi* setup. I got way to much money into my car to add a piece of junk if thats what it is. Anyones input would be appreciated.

 

mine is now working fine. i love it. as for the check valve, i free'd it of debry and stretched the spring a bit to provide more holding power

 

The Devil's Own kit is great. It's just the check valve that I had issues with. I think I got a dud though back in the day however.
