Hi similiar how? do you have any pictures?

thank you!

M-Theory

More info/pics, how did you get past or delete the stock intercooler? If you did, what did you use to connect the turbo charge pipes and temp sensor to the intake manifold? Was the setup split cooling?

I think this will be a fun project while I also add meth to the car.
What GAD used from a earlier post. Below is from a stock CLS 550 or something but similar enough to ours.

guys,

where exactly do you tap into the boost for the meth controller?

I installed my custom meth kit and I logged my IAT. it seems like my Inatke air temp sensor doesn't see the meth all , very small drop in Inatke air temp by the time the car is on the end 5th gear 155 mph my intake temps are 170 f..... nozzles are placed in the charge pipes right before intercooler.

In the middle right where the 2 charge pipes are going into the intercooler there is a plug that's right in the middle . To remove turn and pull. Then just tap into it and reinstall. Atleast that's what I used and it's perfect

Read my post, in pre turbo injection. Basically nip the issue right in the butt. Remember it's the turbo that's causing this heat do to the air being compressed, throw some methanol and it sucks the heat out while. Wing compressed and makes the turbo behave more efficient. There are pros and cons so please do your research

I have my car at the tuner right now, will pick it up today, we also chose charge pipes as position of the noozles. The Meth kit seller Alkycontrol who has been doing this for 20 years told me pre turbo is only if you cannot place noozles elsewhere, he would not recommend it...

I for example also installed a killerchiller, which cols the charge air through the AC, but also noticed through obd IAT sensor I was not able to notice temp changes any lower really at all

increase the methanol flow by decreasing the start and peak boost numbers using the methanol controller.

well it's been working for me. In my big turbo 4cyl for about 7 years now. With out issue. Infact during the fall I remove my pre turbo injection and use solely my post intercooler, during the summer I re install my pre turbo. Every single article I've read personal tried and tested location, pre intercooler is the worst. Best results are post intercooler or pre turbo. I have the graph that clearly shows gains. As long as it flashes and atomizes right you don't have to worry about the turbo impeller wearing. I mean hey what suits you brotha, just figured I'd try and show what has been working for me for years. We just want what's best for our engines lol

Cifdig, is right 100% installing the nozzles on charge pipes is Before the intercooler! is a bad idea it can even hurt the perfomance as the intercooler will lose the efficient to cool. I believe my car lost perfomance. best thing to do is after the intercooler on the manifold in our case so the intake air temp sensor can get hit and reduce the temp , or easy way pre turbo.

I agree pre I/C isn’t optimal but I wouldn’t go as far as to say it’s a bad idea. Post I/C is optimal but it’s also a significantly more difficult job. While my results would no doubt be better with the nozzles that location, I am seeing better IATs with the nozzles in the charge pipes. I don’t know if I’m actually gaining any hp but lower IATs are always a good thing.

Thats not the intake air temp sensor, thats the MAP sensor. Intake temp sensor sit close to the throttle body.

I am spraying 2 big nozzels on the charge pipe and i always log my IAT, i dont see no change in Intake air temp i will report back once i move them pre turbo and then post I/C , how ever my car is a 2012 and i did split the cooling system yet.

Cifdig

What size nozzle do you plan on spraying. Also what rpm /boost level are you going to activate it? Activation time is crucial, you want it to activate while the turbo is about to hit peak that way when they slow down it's not dramatic . The turbo will spin slightly slower not much then pick up and hold the power longer. Look at my graph so you can see when it starts . Every car will behave differently so just play with it until your car feels right. Also remember don't go by butt dyno. To me it felt the same , which I was ok with I simply wanted a cooler charge but I actually gained a bit without tuning for it.

b0kix

I have 3 size nozzles from AEM, small, medium and large i will start with small and is progressive start spraying at 5 psi and full around 12 psi what do you think? I will strap the car on the dyno and see if the power is there and log IAT

chiromikey

I have the same car and haven’t done the split cooling either. I started with the AEM medium jets and couldn’t see any differences in IATs. Went to the smaller jets and saw a 20*f drop on 60-130 pulls.

e65

I have two big nozzles. They were set to start at 8 PSI I turned it down to 2 PSI. Gradually turned the peak flow from 25 to 15 meaning the flow is 100% at 15 psi. This resulted in tremendous Improvement in wide open throttle iat. Also improved my quarter mile

Cifdig

Congrats on achieving your 60hp back and getting great results on your pre turbo injection. Glad you gave it a try . Some are afraid due to the lack of info they have on it. Maybe this will start a path that will lead us to better IAT and More power

b0kix

on cars deff is better pre turbo, charge pipe did not work on my car I lost 60 whp!

Whats the best location and size setup for W/M injection. Im using the AEM V3. Thank you

From reading through this thread, it seems best location for effect is post IC and pre IAT sensor. However this is a harder job to do. Seems also effective and much easier install is pre turbo location. Regarding size nozzle I think this will depend on what mix you going to run.. If you going more water than meth mix then you need a smaller nozzle versus if you going 100% meth mix then you can go bigger nozzle.
