Just got an email from Turner advertising this kit for N52:


https://www.turnermotorsport.com/p-3...injection-kit/

So this is something you never hear about, meth injection on N/A motors. Probably on a hot afternoon the gains can be felt. It lowers the intake temps and I remember from prior research 50 degrees drop is about 11% more power on N/A motors. If it can lower 25 degrees that’s 5.5% more power so maybe 13whp at peak on my motor, but much less lower down in the rev range obviously.

It’s not pricey but I really don’t know if it does anything on N/A applications. Any thoughts? My feeling is it might be a bit of a hassle just dealing with an extra tank and potential leaks, etc.

There's already a thread on this because I saw the same one too! I might consider this down the road, looks interesting!

It's +1% power for every 10*F drop in intake temp.

On a N/A N52, the methanol will do nothing more than water or blue washer fluid. You don't need the methanol for fueling.

It will decrease the intake temp, clean the intake, valves and combustion chamber, cool and slow the burn in the combustion chamber, let you run lower octane gas without detonation, decrease detonation if you are having any, allow you to run more timing or the DME will pull less timing if knock sensor detects any detonation.

It you could monitor knock sensor and timing and find that there is timing advance being reduced, it would be very beneficial.

You could tap into the washer fluid reservoir and eliminate the extra tank issue.

please don't use the washer fluid reservoir for meth. there have been a couple fires in the 335i forum from this.

Don't use meth, use and inject blue washer fluid from the washer fluid reservoir.

What?

Plain blue windshield washer fluid is just a water and methanol mixture. The colder the temperature rating, the higher percentage of methanol (eg -40C fluid is usually 45-50% v/v methanol). I injected washer fluid all day long on my 1.8T without issues

Not completely sure how beneficial WMI is on an N52 though.

my Indy fren said the same about using wiper fluid!!! I was mindblown (since I'm a scrub om this side of the spectrum lmao)
I'd like to just put a legit kit in and use the wiper fluid. :P
Still waiting to hear from the wizard.

Very good advice here.

Always use a dedicated trunk mounted methanol tank or fuel cell.

As far as power benefits for methanol. IAT reduction won't be as much as forced induction platforms, however, the effective octane would be great with methanol. This would allow the knock threshold to increase compared to pump gas. With a custom tuning and methanol injection there could be a decent power increase.

Just so you'll know, Methanol Injection kits are pretty universal in nature. Pump tank lines nozzle and controllers (optional). A boost activated system would not work on these cars for the N/A guys so you'll need to go with the MAF style systems.

Windshield washer fluid is methanol based. Usually a -25 windshield washer fluid is about 25% methanol. In the methanol injection world is not too potent. Some windshield washer fluids have other ingredients that may not be suitable for injection. It's always best to run pure methanol if you have the means and if sourced correctly can actually be cheaper then the WW fluid method.

Also on a N/A application, you have to be careful of not spraying too much water, you can have spark plug blow out or in a worse case hydrolock. I would stay at an injector size of M2 with 50/50 mix and go from there.

Gallon of blue washer fluid is $1.99-$2.99 and is available everywhere.

And if you use the car's window washer fluid reservoir you get a low level alarm for FREE!

Unlike the DI guys, we don't need to use it to help 'fuel' the engine.

Well I'm going to add this to my upgrade list, get this along with my MILVSes in a few months. Got to get my financials back in order after my extended stay in VA.

Whew... Thank the Lord. Finally, an alarm from the factory without having to actually request a basic feature.

This.

Meth and distilled water is not exactly expensive and you only spray when wot. Also, on an NA car you will be using a small nozzle so you are not going to go through it that fast with a decent sized tank. I would suggest doing it right vs using windshield fluid and using that as your reservoir. It's a bit hack. There is also more than just water and meth in some WW fluid. Yes it works, but it is not much more expensive to do it the right way.

I have the aquamist + howerton engineering dual tank and it's a great kit: http://www.e90post.com/forums/showthread.php?t=874263 I would highly recommend both.

+1 on seeing this useless for an n52. Since this uses a Hobbs switch for reference, you would have to make 1+psi to active it.

So you're running this with an NA motor??

Sorry I was not clear, I am running this setup on my single turbo N54.

As far as a way to start the meth flow: The easiest would be a WOT switch so it only flows when the pedal is mashed all the way to the floor. That way it will never come on during daily driving and you also don't use RPM/PSI as a set point to start spraying.

Personally I don't think it's worth spraying meth on an NA N52, I would imagine minimal gains. N52 + Supercharger + Smaller pulley sure, inject some meth and let er rip.

As far as cost, 5 gallons of M1 is $40 bucks. If you mix 50/50 that is roughly 10 gallons. It will take a while for you to use 10 gallons of meth/distilled water spraying on an NA motor.

I'm still curious about this, I'll have to report in when I get this.
