Methanol injection

[MyLonewolf25]

Running meth has a lot of risks.

If you're at WOT and run out, or the nozzle gets clogged, or a line comes loose, or anything else happens and it stops spraying, your motor is done.

Washer fluid is cheap
Do your lines correctly
Check every time you fill up for gas and if you're still paranoid add a sensor that will tell you when it's low

Also if you're putting this much into tuning it
Why not get a stand alone ecu at this point??

Stand alone ECU for methanol injection is cray. Not difficult to tune for, it helps with knock resistance to increase timing. Some people spray before the IAT sensor to cool the charge.

I ran mine as its own system. Honestly I only used water most of the time. I found that water did a better job of cooling the air charge than a 50/50 mix of -20* washer solvent and denatured alcohol. That being said, the 50/50 mix was much better at taking care of tailgaters. That mix would make for an exhaust that would make your eyes burn if you were in the car behind.

That's what I've heard too about water. I hate the idea of hydrolocking the motor in case the solenoid leaks or something bad happens, usually ran straight methanol.

Imho I'd probably just run washer fluid because I'm lazy

But otherwise I'd play around with it and see what works absolutely best and probably have one tune for that and another for just washer fluid
I wouldn't do straight water myself because it freezes up here

My tank, pump, and filter were all located below the spray nozzle. It was a progressive kit that ramped up pressure based on manifold pressure. I never had an issue with a leak and water pooling in the manifold even.

What did you use as a tank?

In that car I used the stock washer solvent tank. It was altered to work with my pump. I kept a jug of solvent behind the seat so that I could reach out and splash the windshield at a light to clean it when needed. This was not in a Sonic.

 

[MyLonewolf25]

Hmmm if and when I do mine I want to see if there any way to keep the stock sprayers working

But still use that tank
Just mess and overall looks cleaner and more stock

Plus space is tight enough as is
And some cars do have a low washer fluid sensor and light
Not sure about the sonic though

Lonewolf - From the kits I've put together in the past, and ones I've bought. It's better to use a solenoid kit + failsafe. Coolingmist, aquamist, and devilsown are good choices, in that order.

I wouldn't put the safety of my rods/valves to my windshield washer spayer, just my opinion though.

True but you can run each system separately
And I'd only be using washer fluid anyway
The only thing they'd share is the tank

But it really all depends
I eventually want to do some cleanup on the engine bay itself and get rid of anything unless and move stuff around to look cleaner

But I'm keeping all creature comforts

I'm really only going to do this after anything in the important part of the warranty runs out and i turbo it

Right now for a few years while I'm saving up my pennies I'm just thinking out loud

Another thing to think about is the siphon effect. The windshield wiper tank fill may be above the manifold entry, I haven't measured. If it's down low in your trunk area, no worries about siphoning fluids/hydrolocking when the car sits.

How did that tune go?

What tune? If you're not injecting meth yet, I know somebody told me that it was the best! It got the car so high! I don't remember who though, might have had something like white in their name. Whitesmoke maybe?

 

[2014 Blue RS]

Assumed you were tuned by now. Meth you would need it.

Me? Oh yeah, I have like 9 different BNR tunes :b Great service, takes a little while though, about a week or so to hear back. I've been dancing around the idea of injecting meth but at the same time I want to go flex fuel. Which do you think would have greater effects? Assuming they're both the same overall cost and that they're both the same level of nuisance. I don't think that's a proper use of the word. It would be that, then GTX turbo, and then clutch upgrade, and I'd be essentially done building the car, for a while at least, and then I'd do the pistons and springs.

Anyway which do you think would be better, E85 or Meth injection?

 

[2014 Blue RS]

I don't know. But meth injection has always interested me more.

Hmm. I guess I'll look for a local supplier to buy meth from then. Gotta find some of that blue.

Local autozone
Washer fluid
Most any regular-20 doesn't use aditives but pure meth isn't exactly expensive either

Most people usually run water meth/washer fluid because it's safer than meth

But there's pros and cons to both

Oh no no. I want that 50/50, but I'm not too sure about spending about $10 a gallon before shipping on boost juice.
