A Couple of rare mods would like your opinions with.

Hi,

What I'm about to post here have been deeply researched and looked for until I came to a conclusion that I will install those mods.. Unless you guys see otherwise, please state the reason why I shouldn't.

My car is a 2012 G37s Sedan 6MT.


The first is a Water/Meth Injection Kit made by AEM.

Water/Methanol Multi Input Injection Kit for MAF, MAP, 0-5V or IDC | AEM

Well, the reasons for thinking of getting this mod are:

1) The bad 95 RON (90-91 AKI) pump gas around here. And no other higher Octane gas than this. Could get VP race gas but it's very expensive because it's illegal here.

2) The hot weather in the Summer which could easily reach 115 F at day time.

This is a cheap way to increase the Octane rating and reduce the temps when it's necessary. A 165 KG drum of Methanol here is about $205 (yes it's measured by mass not volume when making a % mix with water).

3) Tuning. Recently I got my car EcuTek E-tuned by a pro tuner which is well known here in the forums. Let me just say it wasn't a pleasant experience tuning with him. Nevertheless, He netted me around 3 WHP up top and around 7-9 WHP in mid to high RPM range. I was actually expecting more but this is the maximum the car can get with the gas available here according to what he stated.

So I showed my data logs to another tuner as I came to a dead end with the one who tuned my car. The second one told me that the car easily knocks and recommended me to get a race gas to see if there will be any knock corrections at a 4th gear pull on the aggressive map.

For that, I made the old school Toluene/Pump gas mix and increased the Octane rating to about 94 AKI. Used this site to mix the right ratio (Octane Mixture Calculator). Result was as expected, no knock corrections occurred throughout the pull. Meaning there is a place for more timing and more power to be gained.

That is all to know about the first mod.

The second one came to my mind when was researching the water meth mod.

Crankcase Evacuation System

This is necessary to prevent the crankcase get contaminated by the water/meth mix that could get in from the small tubes at the intake tubing which is feeding fresh air to the crankcase.

This can be done by installing caps on these small ports on the intake tubes so the water meth would only flow through the throttle bodies into the combustion chambers.

This mod will also help in making more vacuum in the crankcase which is good for the seals and the performance of the engine.

I'm just not sure about the set up of the crankcase evac system whether at the PCV or the valve covers ports. Would like your help in how to set it up.

Any opinions & thoughts would be appreciated.


Thanks
