Amount of use doesn't really seem to matter. There is still meth just sitting in the pump when not in use. The green light will come on much quicker after a pump replacement.

It's pure meth that kills the pump. If you run a mix it will last many years. I think mine is going 5 years now.

What mix are you running?

realcanuk

I've run just windshield washer which was about 35% meth, and sometimes meth mixed with WW which would be about 75% meth. To be honest don't notice a difference. Might be a few HP but I haven't compared on a dyno.

How much higher were your IAT 's running the washer fluid vs the pure meth? I have a 5 gallon can of pure meth from Southern Racing Fuels , probably try the washer fluid route next, especially if I keep my setting on 8. Getting into boost is not to hard at only 3300 rpm, so it chews through meth if you really want to do some frequent pulls

realcanuk

Never noticed much difference but in my opinion the reading is a bit of BS because we are spraying the sensor. I would think that some water would actually have lower temps in the combustion chamber, but that is just my thinking. I don't really know for a fact. When my car dyno'd 1008 it was running a mix. I cant imagine it could have been much more on pure meth. Iats read 70 on that pull.

1,008 rwhp , sounds like a monster ! Guess I will try the WW fluid when this 5 gallon can I have runs dry. Maybe the WW mix will extend the life of the alky pump ?

Just make sure you use only blue fluid, and the lower the freezing point, the more meth content.

Got it, I did hear that mentioned before. I'm assuming walmart has the jugs and best price ??

realcanuk

I don't know. In Canada things usually different.

Look up the MSDS sheet for the one you want to buy. It will tell you the meth content and other ingredients. As an example this one is 40-45% meth, and no other crap in it.

I am not arguing with Realcanucks results as 4 digit hp through an auto is fantastic, but why are you insistent on converting to a mix? I think you should at least pick up the phone and call Julio and discuss this with him. Methanol has some properties that benefit over water including flash point. If it is cold outside water will not vaporize like methanol will. All you have to lose is about 30 minutes because Julio talk your ear off. 813-265-1400

I'm in Florida, so it is hot as ***** most of the time so the vaporizing issue of water should not be too much of an issue.I see this Julio cat you mention has an 813 area code, that is not to far from where I am , the Clearwater / Tampa Bay area. You have an address to his shop ?

Thank you sir !

Julio is alky control and knows his stuff. That's said most who are out every maximum hp in the corvette world will say meth only is better.In many other circles they swear by a mix. Lots of serious drift cars run water injection. I think its an endless debate really.

Relevant data on pure methanol vs 50/50 vs water only. It's a C7 with centri SC making around 600 whp so pretty applicable to most sc setups on here:

https://www.enginelabs.com/engine-te...-adds-42-rwhp/

Cliffs: pure methanol makes more power, but only 8 hp peak or 5 hp average thru the rev range. Both make quite a bit more than pump 93 only and water only is pretty useless (from a power perspective). This test does not explore smaller pulley/higher boost... just a constant boost pressure, adjusting AFR and timing only with various fuels.

I know everyone parrots 100 methanol is the only way to go, but this test makes a solid case for 50/50 (with appropriate nozzle selection..... you don't want to inject too much water) for a lot of guys. Less volatile mix, you get the perks of water injection (lower EGT, cooler in cylinder temps), a little cheaper, maybe a slight annoyance to have to mix depending on how much you go thru. I think the water in cylinder cooling aspect is a great for stock engines with tight ring gaps.

realcanuk

Been saying this for years around here but the experts always show up to say that pure meth is the only way to go. For the few HP less I'll take the safety and less maintenance of the mix.

BIGMAC

This article makes a seemingly strong case for 50/50 mix vs 100% meth. Has anyone been in direct contact with Julio at Alky Control about his personal pro and con evaluation? I am sure Julio has been asked this 1,000 times and I don't want to be #1,001

If I have time this afternoon I'll call him and share this link!

I’m in Tampa for work, plan on trying to stop by and get a second pump that way I always have a fresh pump on deck! I’ve got a few questions myself everything I’ve heard and in any of my email traffic he seems to be an extremely knowledgeable and all round decent guy. So if anyone has specifics and doesn’t want to call or email send it....
