I was curiously looking at my lower cp and planning out where exactly I was going to tap it for my meth injector and I was thinking about how it should be set up.

Instead of drilling it in the side of the pipe 5-6 inches from the TB, I was thinking of tapping it right where the bend is so the nozzle sprays up directly at the TB. Theres room and the nozzle shouldn't hang down too low as to get road debris messing with it or anything. I could even make a block-off plate/skid plate for right under it as well.

Has anyone successfully done this?

I'm not sure of the toubles and tribulations I'd have with drilling and tapping on a bend and I was wondering if it's even going to work. Would it thread in and seal properly? I've never done this on a bend in anything before.

 

sub'd

 

I wouldn't see any reason as to why this wouldn't work. Just make sure you use plenty of sealant. Now as far as benefits, I don't see it helping tremendously, but its bound to help a measurable amount.

 

That was where I located mine from under the car for the second try. I had it in the MAF relocate plate on the ZZP CP first but it was too close to the TB.

I drilled the elbow from under the car & tapped it, popped the CP off & blew it out well before firing it up. I doubt any chips went inside the CP from drilling it on the car but better safe than sorry. The nozzle & line didn't hang any lower than the subframe/radiator support as I remember and RTV is FTW!

 

You have any issues with the meth flowing across your maf sensor? I heard bad juju about letting the meth go across it and them going bad.

 

MAF sensor was in the intake pipe pre turbo.

The Lower MAP was before the spray in the ZZP lower CP both locations I tried.

The MAP sensor in the intake mani is going to get sprayed no matter what. No issues on mine.

You are correct that the MAF sensor cannot get wet, that's one of the reasons why I moved it back into the intake pre turbo. There were other MAF issues when I went blow through MAF in the lower CP.

 

Ah, ok. Well, I'm going to have to try to get a super atomizing nozzle since I'm running a blow thru maf setup with the BYT Throttle Body Spacer. I think cooling mist sells them. I'd like to go 12gph anyways.

 

Nice!

So you pretty much drilled, taped and then used RTV to make sure it sealed to the cp? I'm going to try and tap it there as soon as I get the 1/8 NPT tap. I've been wanting to do this location for a while now but feared it wouldn't work due to the bend. Thanks for your input!

And FasterIsBetter, I'm certain it would benefit a bit more because you're not spraying it at the wall of the charge pipe causing it to just pool up. This way more will atomize in the air stream and move with the airflow towards the TB. I think it'll work great!

Thanks for all your input guys!

 

12 gph is WAAAAY too much.

 

Not for a PTE6262....I'll be running that later this year. Also a 12gph would be just slightly too big for the S256ET. The turbo flows over 50lb/min....and the system is a progressive system.

 

14gph ?

 

Lol, smart ass!

 

It's too large, especially given that the rating is for a 100psi behind it. The newer 250psi pumps probably provide about 175 psi with that large a nozzle. Besides, smaller nozzles offer better atomization.

 

My AEM pump provides 150psi. I'm using the 9gph nozzle provided with the kit until I run the PTE6262 which can support over 700hp. Thats when the 12gph nozzle will be needed. Its either that or I'll run dual meth nozzles.

 

Unless you have some ancient kit from AEM, they run 200 or 250 psi recirculating style pumps (depending on the pump vendor). No one runs the old pulsing pumps anymore, and if you have one of those, I would throw it away.

 

Its the AEM kit from MPx. They specify the pump as a 150psi pump. I never opened my kit so I'm not 100% sure it isn't a 250psi pump. Regardless, they specify their largest nozzle in the kit as a 650hp nozzle rated for 9gph.

 

That's the kit I have. Phenomenal Progressive Kit if you ask me.

 

Gremlin, start with a 5 gpm or 7 gpm nozzle at most and don't go more than 49% meth, it becomes flammable at a higher mix than that. One backfire on a shift could ignite your system if it's too volatile a mix. Granted it'd prob be sucked into the intake but what if it blew off a CP? Nasty engine fire could result.

It scares me when I read guys running 70% or higher meth.

I activated mine around 10 psi boost, but if you have a progressive controller you can bring it in sooner.

 

Voice of reason.

 

Old vs new pumps:

Believe it or not, methanol isn't as flammable as most people think. Gas is WAY more flammable and volatile than Meth.

 

Regardless, you only want about 15% of your fuel from methanol.

 

And exactly my point. 7gpm nozzle on the stock turbo which flows less than 2/3 what the S256 does and half of what the 6262 does. More airflow means more fuel/meth required. Double the airflow means double the fuel. Correct me if I am wrong here but 7x2=14? So technically I'd be a lil below the threshold and more along about exactly what I'd need.

 

Never use a meth spray to make up for a lack of fuel. The meth/water mix is for cyl charge cooling.

If you need more fuel, find a better solution than spraying it into the TB.

 

Yeah I was kinda curious about this comment too... Meth is supposed to be complimentary not supplementary right?
