Meth "Purge" Video - SRT Forums

Gmanigio · 06-06-2008, 03:11 PM

I wanna thank everyone that helped me wire this up in the other thread I started

The reason why I thought of this is because about 2 weeks ago I went to the track. On the way there I had a feeling meth wasnt spraying. So when I parked at the track I powered the Pump from the battery and noticed NOTHING was coming out for 10 seconds. The tank was full cuz I filled it the day before. I think air got into the lines cuz the meth was low.
So after another 5 seconds, meth started to shoot out. I wanted to eliminate the getting out of the car, getting the wire from the power wire of the pump and opening the hood and etc...etc...

All you need is a tiny tap, any more than that and the car will bog with Less than 10.0 A/F.

A tiny tap will show the meth getting injected and drop the A/F some.

If there is anyone that thinks I am going to be doing damage to any part of my car by just tapping, let me know.

ADDED:

The red switch on the left in the video is my "on/Off" switch, which is the toggle switch in the picture above.

With that switch "OFF" the Meth will NEVER Turn on even when it sees the pre-set boost.

Then the momentary switch which I just added today.

nice setup there. love the indicator light showing when the meth is on.

nice..
so where's the how-to? what's the wiring looking like?

glad to see it worked out for you man. i would suggest having the rpms at maybe around 2000 when you "purge" it to prevent any pooling in the charge pipes or intercooler.

The middle hole with the 2 wires is setup for another light, the one I bought was 120V and would not light up.

I set this up by the info given by other members in the other thread I started.

Basically its from a Devils Own kit that runs a RELAY:

1 - 1 Momentary switch from Radio Shack
2 - Run one end of the switch to #85 of the relay
3 - Run the other end to Ground

And it is basically doing the job of the "boost switch" when you press the button.

Just for a second I dont think would hurt anything. Besides....during the burnout it will all get sucked away anyway

Just more fuel.........

nice...

daniel427ss · 06-06-2008, 10:36 PM

where do u have the meth injector placed

Gmanigio · 06-06-2008, 10:52 PM

The injector is about 8 inches from the TB, AFTER the sensor.

Also, it is Literally just a TAP, any more than that and it will bog.

I am thinking about adding another nozzle before the sensor, another M5, wondering if Purging then would be too much meth....

ive turned my pump on when idling and my engine doesnt hesitate like yours n my nozzle is like a m9 or something like that n i am also right before the throttle body-like 5-7inches

daniel427ss · 06-06-2008, 11:02 PM

then i rev it a little n see that the hks bov spits the meth lol

so what happens is that it doesnt go to the engine while idling is cuz its alot of heavy spray?

Gmanigio · 06-06-2008, 11:12 PM

Ill have to look at my BOV.......

But it is literally just a tap, I cant see there being a puddle....

At idle, how much air is going through that pipe? I think Im gunna rev to 2,000 from now on, like the other guy stated.

if u rev is going to be more dificult to see a diference unles u stay at a steady 2000 rpm n not move anythin more or less. (ive tried it)

n me being so so curious ive also done the tappin n tappin n tapping a couple of times some for like a second to see if my engine does any difference during idle n when i see no difference,
just to be safe,
i do a high rev so anything accumulated goes in for combustion-if not then the bov spits it(of course it wont be all of the meth but whatever left is no deal)

i also wanted to put another injector before the sensor so it can see the meth temperatures

Gmanigio · 06-06-2008, 11:32 PM

I was thinking the same thing about the reving, Although shouldnt the A/F stay at a constant 14.7 no matter the reving??

I will try tomorrow.

I know that if I held it for close to a second, it bogged, just like in the video.
