Hey guys. Quick question.
Me (e55) and a friend of mine (e63 weistec charged) are planning to install meth injection to cool intake temps and not get timing pulled towards the top.

Being in georgia, the actual juice is hard to get and frankly such a pain in the *** that its not worth it. So, if we use medical spirit 96.6% alcohol 50/50 with water what negative effects ar we looking at? Is it gn be bad in any way for the engine? Should we use jsut 100% alcohol or even 100% water just to cool? Octain bump isnt the primary concern ar this point.

Thanks

 

Small nozzle and 100% distilled water

 

2 nozzles or 1? Pre and post blower?

 

1 post, make sure it's small when doing 100% distilled water

 

What about ice tank in the trunk? Will that do the trick?

 

Interesting...

How much cooler would the IATs run with a water injection?
What product do you recommend for the 55 AMGs ?

 

That only works when you pack it with ice

 

Best is aquamist, nothing better than that

Great review there... already with very small injection, a reducing of 33 degrees in IAT. WOW that potential is huge.
Tune needs to be adjusted as they say or we 55AMG users "only" use it for colder IATs?

 

Tune will not be adjusted with water injection. It's purely for cooling and anti detonation

 

^^^^This.

 

Hulk is providing good information

I run 9:1 distilled water to HEET on a CM10 post blower. The 10% methanol is only used because on the CM10 nozzle, I get a slight bog on shifts... If I pulled the blower and swapped for a CM7, I'd run 100% water

 

I have a snow performance stage 3 with 2 nozzel kit which gives me every option I could ever want.

 

Nothing really compares to the aquamist simply because it's like using injector duty cycle.
Snow is good but can't compare the 2.

 

I don't honestly know anything about the aquamist cause I have always used snow. I run mine off both boost and duty cycle with the pump set to ramp in as it goes up.

 

Aquamist is an expensive system, but if I were to do it over I would use aquamist in a heart beat

The system is a work of art

 

I use the AEM kit. Two of the smallest nozzles in the surge tanks. Set to kick on at fairly low boost. I'll have to look. I'll likely do a trunk tank soon though. At the track my IATs start around 110. Even with the meth it's difficult to keep it under 145-150 on a run starting at 110. I need a way to start much lower. She's at least very consistent with the meth.

 

If you have them in the surge tanks, you're spraying after the IAT sensor so you're not getting the timing advantage

 

^^^ This. Your cylinders are running cooler but your sensor is not seeing that drop in temp so its retarding timing. My guess is your only benefit spraying post IAT is reduced knock retard and how substantial that is depends on the quality of fuel in your gas tank.

 

I'm trying to decide between meth and NOS. If I were to go with meth, which aquamist system would be most appropriate for the E55?

 

HFS-3 should be really good

 

Thanks Hulk!

 

Correct. Which is why there was no HP advantage just repeatable performance is all that was gained.

 

There's a lot to be said for repeatable performance, right? It sucks to have a fast fun car that only has it's full power available once then falls on it's face.

 

Yessir. It's easy to get a big number in these cars with ice and some cold weather. Doing it twice within a few minutes is a whole different story. It's really the biggest advantage NA cars have over these cars.
