Anyone seen the new Engine Masters with meth?

I honestly have been back and forth with running an air to water e85 or e85 with meth and no intercooler. Id probably do preturbo and post injection if i go meth. I keep floundering back and forth. Ill drive to work on my hour commute and by the time i arrive im sure its meth then after work i hit home and look at a2ws. Who knows i already own the meth stuff so theres that but i figured out how to build my own ac chiller deal for the a2w out of a beer wort cooler so who knows. When i saw they were doing this i was like great maybe some answer but the engine masters deal really didnt answer anything in my opinion. They just didnt seem like they even tried to make the water/meth work. They just figured out it wasnt atomizing and said well you need a different intake. The end.
As said elsewhere, it was a very flawed test. Although RH did say they tried varying amounts of water/meth that wasnt shown, so we can only take his word for that.
But on a lowish boost, low charge temp setup....already running race fuel, so not a chance of the engine being knock limited for water injection to actually perform....well it was an odd test really.
The intake runner temp test however was interesting. But without seeing all 8 runners tested at the same time and held on load for a period to really get a good picture and ensure the TC isnt lagging etc....again, harder to really take the results as valid.

Too much water, it takes very little water to cool the air down enough to where no more water will vaporize and give them what happened. Methanol vaporizes a lot easier (lower air temp) and it takes more of it to cool down the same amount of air as water, so if they tested 100% methanol it probably would have been a great test. Water sucks for injecting unless you use the absolute perfect tiny amount, methanol is a lot more forgiving.
E85 is great when you make enough power to require it and its available. But under 850whp or so its basically just a hassle. Lots of people like being able to drive where they want and not have to drag fuel jugs along or plan out stops for E85 stations.

First the "temp" they saw spraying isnt the the real temperature plain and simple.
Even though it isn't the true temperature and shouldn't be taken as such it does still show the flow discrepancy across the manifold
If you don't think that cylinder distribution is an important issue as you are adding a means of fuel, you best stay with the low power stuff

right if you're DDing it it's nice to have flex fuel like I did on my blue truck. just keep the boost turned down. I'll probably do the same set up on the malibu even though it's only 700ish wheel
and honestly if anything i think their test showed exactly how water meth works for us. 7&8 get the lions share of the mix...and those are the ones that tend to go lean
there's no one-size fits all solution. but I cant even bicker whole heartedly...I'm just happy to be alive in a time when cars are sold with 1000 hp and a warranty. and I can make 700 wheel for $3k drivetrain & turbo

My advice then would be put meth on your car and see how it works for you. I run E because it’s readily available for me and I feel it’s better than pump plus meth. That’s just my opinion and if E wasn’t available to me I’d already have meth on the car.
woud a wet flow mani be a better test? sure? but that aint gonna fit on my car
what would make better episodes if if they did something other than LS/Coyote/BBC/SBC
lemme see a J41 olds motor or a 409 with tri power

You don't have to change manifolds to distribute meth properly, plenty of direct port options you can install as I've used them in plastic and metal manifolds. I think they are appealing to the masses, a 6.7L that barely cracks 400hp doesn't exactly draw the viewers in.
Agree, why I like Holley (as well as other ECM's) that allow per cylinder correction.

There is some heat transfer in the charge pipe/runner and you can supplement that with an additional injector pre manifold and in some cases pre turbo. However, cylinder cooling is the main goal and the water absorbs heat on compression and vaporization. Vaporizing is where you get the steam cleaning effect on the engines that run water/meth. While it can be used for only cooling, many use the systems for additional fuel. My IAT rarely goes above 100 degrees so I use it for the additional timing/boost then I would be able to run on pump gas alone.

And again, that's overlooking the fact that most of the important work of water injection, especially when water is involved happens inside the chamber. But on a low boost engine running race fuel where knock isnt even remotely an issue.....it's almost utterly pointless running water.
Although I guess the one argument they might offer for the test...was they were only comparing charge cooler...vs no chargecooler. Which is a little different again
In that case is it possible to mix methanol with pump gas at the desired percentage and just run it through your regular fuel system/injectors. I know running methanol is an issue with most fuel systems not capable of handling it, but is there a percentage where you could get positive results without being an issue for a fuel system capable of handling e85? Say pump gas with a 25 percent mix of methanol? Just curious.
