My first single turbo build
Water meth mix is something I do not understand. You get the ability to increase power with the added cooling and octane of meth, then you **** on your own parade by putting water in the mix. Water certainly has the ability to cool your charge, right up to the point of not allowing it to burn at all. The only advantage of water is cost and lack of corrosion.
50/50 with water makes it safer from a fire hazard stand point if you have a leak.
Like everyhing I recommend though do it right or don’t do it at all. If you’re going to use meth use good stuff and do it right.

It's recommended to not exceed 50/50 at BCNUL8R said because flammability increases above this. Water has the ability to absorb heat, cooling the intake charge, until it turns to steam. Meth adds octane. Two different benefits.
You guys are gonna think I’m crazy. But hear me out. I’m thinking I’m going to put a couple small cooling fans on my intercooler. Yes yes I know. There’s people that say it’s stupid. Waste of time. I’m trying to fix a problem that does not exist. O the fans are gonna block flow. But I beg to differ. Example. I live in the south. At times there’s lots of traffic. My iats will get 130-140-150. Yep, I know it cools down when I start moving. But. Like today. Sitting in traffic. Hellcat next to me. We merge in the interstate side by side. Hellcat wants some. I didn’t bother because my iats are high. Well and I don’t do that **** around a bunch of other cars. Too dangerous. But still. Had it just been me and the hellcat, I might would have wanted to play if my iat’s were in check. This is also another reason for the light meth shot I want to add.
btw. The fans aren’t gonna any flow. It’ll get air through there no problem
Ok. Now let me have it. Lol

if you could run e85 it will help you big time!
im running e85 and i think i have spal fans they pump out 2500cfm from the radiator, i know summit has some that pump 3100cfm i think?
the fan infront of the intercooler isnt a dumb idea i think. IIRC rally cars used to do something like that similar, Even STI/WRX used to or still have a intercooler sprayer that sprays im pretty sure water on the intercooler to cool it down!

no e85 here. We have one or two in town. My fuel system wont support it either. The fans will go behind the intercooler, two 8" puller. Spal replicas.
Dont think the track would appreciate me dripping water all over the place. to add to it, Fans would help in the staging lanes.
Why? have you tried it? what results did you have?
I dont know. Its a bar and plate, looks like quality one. 2.5" inlet, outlet. 3" thick, bout 8"-9" tall and arount 23" wide. I bought it from a buddy lightly used, he said it was a namebrand but I forgot which name.
They become a restriction at speed since 50 mph airflow is way more than a small fan on an A2A. Basically you end up blocking the backside of the A2A. Sure it'll help at idle...but you don't race at idle.
have you tested this? Or is it theory? I'd like to hear your actual results. My buddy had some on his supercharged silverado and I ran logs and from what I remember, It helped. Not like a huge difference, but he said in traffic it helped alot. I just text him to confirm, but this I what i remember.
I guess This is what i'll do. I'll log the car without. Then I'll add em. log again. try to to the same things. and compare. They work, they stay. The cause a increase in temps, they come off.
I know itll be hard to make it exact, but i'll try. The main thing is the decrease in idle temps hopefully. usually my iat at cruise is 10-15 degrees above ambient.

The majority of your cooling on a street car from an A2A comes from the intercooler acting as a heat sink, not from airflow moving through the cooler. Meaning you'd have to move a TON of air at idle to cool this heat sink to make a major difference on IATs. Look at the OEM setups, they don't use fans, and surely would if it was necessary. I have seen IAT differences based on how close or far the FMIC is from the radiator vs the grill on an Fbody and blocking the back of the FMIC is similar to people who run pushers and pullers on a radiator. You end up with turbulence and the airflow having to fight to get through it.

but you still have not answered if you've tested this. If you have, I take your word for it. If you havent and speaking from theory, or repeating what others have said, with no actual experience, well then I dont have to say how i feel about that.
I guess maybe it acts like a heat sink, but its and air cooled heat sink. Conventional wisdom tells me that if you have a heat sink in stagnant air with no circulation, you'll have an imcrease of heat. But if you add some air movement to it, it will cool down. I also have to disagree with you saying it need a TON of air to cool it, it will start cooling down moving lees than 10mph. I would not think thats a ton of air. I edited my above post too if you havent reread it.

The problem with water...is quantities need proper regulation, which seems beyond mosts abilities. Whereas methanol..any idiot can dump a shitload in and yield positive results.
Why test water/meth or anything like it....on a low power engine ( relatively speaking ) running race fuel and lowish boost ? It makes no sense. A lot of the benefit of WI is where an engine is knock limited ( again...back to what happens in the chamber, not just charge temps ) on poor fuel, and WI can allow improvements.
On an engine with race fuel, it is almost pointless, especially when they proved charge temps werent really a concern anyway
Then getting back to gametechs thoughts on water....2 nozzles with a poor water/meth mix ? Seems an insane amount to be injecting again for relatively low power/temps. It makes little sense...and not surprising it damped the power/torque until higher in the rpm range. That was a very poor choice on their part, and they should have tried less fluid.....again also coming back to the fact they were using race fuel anyway, so there was never going to be any need to add water or even meth.
Really, the only actually useful test they seemed to do was the intake runner temp test, which may give some indication of how much water/meth was passing that runner. Would have been nice to see all 8 at once though

umm ok. Lol.
I guess i just like to follow advice from actual experience. Sorry if I offended you. You’ve given me good advice in the past that I’m thankful for. Not saying this isn’t good advice, I just like real world data or personal experience.

It's only $60 a year or something.
Although have to say when I subscribed, I had expected a hell of a lot more episodes of Engine masters than one a month or whatever it is. Yes the subscription includes a lot of other stuff ( even if a lot is also barred in my region as they state it ), but most of it I didnt give a **** about.
Really there is little reason why they couldnt do a weekly show, I'm sure they would get a lot more subscribers for it.
