spraying meth after the supercharger
spraying meth after the supercharger
Ive tried searching on the forum about spraying meth after the supercharger...unable to really find any info on how it worked, benefits, or if anyone has really done it.. a couple people have mention about zzp or intense(not surewhich) has made a kit as well but no info on if people...
any info on if its worth doing after the sc... and for tuning, would it be simular to before the sc setup... i was planning on spray before and after, just for experiment really, but not sure if its worth it or would benefit at all
thanks for your help

this has been discussed about using nitrous several times. there is a spacer plate that is tapped and you just plug your fitting in and call it a day. Now if it's more efficient or not??? common sense would say yes but I've never done it. There used to be worries about sparying through the SC way back in the day but over much discussion and research most people decided the SC would be just fine with the meth and nitrous going through it. I think it's just personal preference honestly.
great thanks for the help...so pretty much spraying before and after the sc at the same time is pretty much overkill?
bump...anybody else have any ideas or info about this?

well, if you spray like 1.5gph before and 1.5gph after, then thats fine.... thats the equivalent to a 3gph nozzle, which appears to be standard here, but 3gph both before and after might be overkill...lol
lol i thought so... but i thought i would get as much info as i could onthe subject... as far as performance wise do you think its any better to spray after rather than before....ive already seen alot of the threads on how meth could possibly eat the coating on the rotors but not sure if the supercharger itselfs could take away some of the potential of the meth... lol not sure how to explain it but just trying to try something differant... i guess the only real way to know is just to do it but just trying to get some info on it
thanks again
thanks again
yea defantly not alot of room for error when tapping into the IM, i think tapping into that would cause more problems later than the beneifts would help, i think im going to purchase the sc spacer and im in the process of buying a meth kit... maybe ill also purchase a TB spacer so thay way i can test both ways, and i could plug the hole in the spacer if need be in order to compare the two... thanks for your help... ill keep everyone updated once i get the meth installed and spacer installed....
but until then anymore info is greatly appreciated

i have been spraying nitrous for quite some time now and i had my blower off this past weekend. the rotors on the SC look exactly the same as the other time i took off the blower before nitrous
thanks any info is great, from what everybody online is spray before the SC im almost certain that spraying before does not damage anything, just didnt know if there was any beneifit to spray after
Then the SC will be cooled from the water/meth mixture. Someone once told me that their SC stays cool while spray with meth. I didn't believe it until i tried it myself.
Installed a Devil's Own progressive meth and did some logging which included several WOT pulls. When I got home my SC was cold. REALLY!
oh i belive you... i just got done doing a custom SINGLE pass IM and got done bleeding everything and see how the IATs react now... one thing i really noticed though that ive never checked is how hot the SC got after i was drving... i could touch it, but defantly not hold my hand on it very long... thats when i knew i had to get meth if the sc was getting that hot...
im also running 60's with 2.79 pully..plus many more mods
hopefully with the meth i can get things cooled down here...and just for clarification, meth will lower iat2 or iat1, or both for that matter?

Spraying into the intake or spacer before the supercharger will not lower iat2 temperatures; though it will boost your octane. The argument of whether or not it will ruin the supercharger if not maintenanced is questionable... I know someone who claims it doesn't effect the blower., and another who claimed he had to maintenance it on a regular basis.
Jegs.com sells a 1/8" bung for your meth nozzle; use that and tap your intake manifold.
I've seen fantastic effects from spraying into the intake manifold; without any risk of damaging the blower, by cooling the IAT2 temps HEAD ON.

Right in the dead front center.
I personaly know someone who ran dual 3gph nozzles into his intake manifold.
You may know him as WSFRAZIER on here
that was his only cooling mods for his 2.5 & 60s setup.

Explain please?
by dead front cent do you mean right below wehre the sc sits... like on the bend of the 180 degree turn of the IM? or does it really make a differance... im thinking about spraying a 2 gph nozzle before the TB and a single 2 gph into the intake mani....
Spraying before the blower will only dissapate the methonal and water and not cool the INTAKE AIR TEMPERATUREs within the intake manifold to the dramatic temperatures that companies claim on our car. You will get the octane boost from it depending on the methanol mixture.
spraying directly into the intake manifold you are DIRECTLY chemically cooling the oncoming heated air coming from the supercharger and getting the octane effect.
If your looking at the engine bay; directly under neath the blower on the front side of the intake manifold. I have it tapped in the center of the front side of the intake manifold...
When I get my car back from the body shop I wouldn't mind taking a photo for you.
What size pulley are you running? That would work; I never used below a 3gph nozzle myself.

In reality, spraying before the blower may help in the atomization of the air/water/meth mixture providing a better vapor. And spraying before the SC cools the SC and IM which combats heat soak.
The blower gets so hot, that the meth/water vaporizes. There is almost no trace of the chemical cooling making it to the intake manifold. The blower does not cool enough to provide a cool air passage into the intake manifold.
I just tell it as I see it; not pulling random info out of my ass.
This is from what I've seen in a 2.6 pullied meth lsj. I've seen both meth options ran, and the obvious winner was the direct spray into the I.M.

According to what you are saying none of the mixture is making it to the IM so none of it should be making it into my engine.
i can defantly see how the sc can disapait some of the water out of the mixture... and in return not work as effectivly... but at the same time even tho it is not working as effectivly for octane boost, i cant see how it would NOT cool the sc at the same time... which defantly does not hurt anything for heat soak
im currantly running 2.8 pully and after driving for about 30 min, not really heavy driving, i cant hold my hand on the sc...to hot, so if the sc itself is NOT hot the air coming out of it is only that much cooler...
but the whole reason why i wanted to add the sc spacer for meth is like steven said, spraying directly into the IM would have the best results... no loss of anything...
so i think im going to have one nozzle before the sc, and one after
but would there be any differance is the sc spacer, and tapping the intake mani?
and if you could get that pic that would be wonderful thanks!
thanks for all your help guys!

Really? So if all the meth/water vaporizes in the SC and does not make it to the IM why did my AFRs go from 11.8 to 11.1 after adding water/meth?
According to what you are saying none of the mixture is making it to the IM so none of it should be making it into my engine.

So I think your theory is a little flawed. The only way to get the meth/water mixture into the head as you describe would be use a IM to head spacer plate like this.


Get 4 1gph nozzels and spray directly into each intake port.

That is not true. I have logs to show that not only do the temps drop but they also stay cooler much longer then with out meth.
