Pre-Blower Meth?
I have heard of guys doing 3 nozzle meth setups with a nozzle pre blower. How are the results from this? Can it be done with a 50/50 mixture? Boost juice in particular because that is what I run. Does the 100% meth damage the blower or would boostjuice? This is my biggest concern. Also, where does the meth sprayed pre blower ultimately endup.
Also, can it be done with a snow meth kit? I know I know I don't have the alky control/ECS kit I may switch down the road.
I can't find a whole lot on this searching.
Btw my car is A&A Si trim kit if it matters

If you have a while....

At a lower level where you arent pushing the compressor hard, I cant imagine it being any real benefit.
If you are, then it may be.
The liquid itself wont do the blades any harm if done correctly, although methanol itself may cause some deterioration over time.
A friend in the UK with a ProMod car that tuns methanol had his wheels hard anodised for durability as they spray a lot of meth pre-compressor as well as injecting as normal into the intake ports.
Ive only recently started spraying some myself, but I also spray pre TB as well. So it will be hard to judge any results.
I just figure any additional cooling it can offer can do no harm, and it seems cooling a compressor at this early stage when pushing the compressor very hard can improve it's efficiency

My tuner wasn't comfortable with this. I am using the snow kit and they want a meth/water mix. He was not crazy about putting 100% meth under the hood having another combustable chemical under hood.

I got a little fitting waterjetted out to fit a nozzle pre-compressor. The jets Aquamist use are much smaller and neater than anyone elses, so dont take up much room within the inlet tract.

I ran preblower meth for about 3 yrs on A&A S-trim with 3.0" Reichard Ultra-grip.
Never noted any degradation on the impeller. Traded it in to Andy and he didn't find anything wrong either.
The preblower setup yielded little.
About 1 psi increase above 6k rpm as I recall; couldn't tell any difference unless I was pushing it hard. On the street I couldn't see any difference; No traction at high rpm.
On the strip I saw the 1 psi improvement at peak rpm.
Logged boost on HPtuners.
As noted earlier: use only if you're looking for every last ounce of power.
Good Luck!

Do you think a 3.4 pulley would be swinging the blower hard enough to see any benefit?

Nothing in particular just wanted to hear more success or horror stories with this I didn't realize how little this is done at least on this forum.

But most turbocharged methanol cars Ive seen place injectors before the compressor as well as after and of course close to the intake valve.
So they too are doing it to help cool the compressor and also intake charge
There is some good stuff in the link, so it is worth taking the time to read through it. Some guys have more data than others.
But there arent really any negatives that I can see. Positives...harder to measure if you're also injecting pre TB, but the placement achieves two different things
Pre-TB is about cooling the intake charge, but you're also aiming to cool the combustion chamber too.
Pre-compressor is all about intake charge cooling and helping the compressor do less work which means IC has to do less work, the setup can work better.

I'm running a 3 nozzle Alky Control setup. M3 pre SC and a M10 and M15 after the intercooler. I added the pre SC to try to drop my IAT's. Didn't notice much of a change in IAT and never dynoed before and after. No negative so far running it. I think I need a bigger intercooler more than adding the extra nozzle.

Ran the same size jets exactly with the S-trim.
Didn't notice AIT drop but boost was up about 1 psi peak only.
I think you have to get outside of the compressor map sweet spot to get the most benefit...
Never noted any negative impact.
Yea, Heard u had a small intercooler unit (and adding the extra nozzle didn't work)!

I guess most dont do it as they just stick with injecting pre-TB which works very well.

Thanks this may happen down the road along with a head swap
