Water Methanol Injection instead of a bigger intercooler...?

So if there is a seperate software just for the manifold to work then how would you go about a custom tune as I doubt IE would cater for all turbo build setups.
may be worth buying and letting somewhere like Rtech map this.
Unless youd have to go standalone ECU to map it?

Maybe @rtechniki can answer if he can make this manifold work like the IE tune can. For what I've read seems like Unitronic, APR and Revo don't really work well with it. :confused:

Lol, didn't realise that about a specific tune needed for the IE manifold! Their's seemed really decent with the CAD optimized velocity stacks....all the good stuff. What a shame!
It reminds me of HPA's intake for the R32. Someone fitted one and it lost 50lbft over the standard intake immediately :grin: Lots of forum debate about it. HPA got involved and said (surprise surprise) "you need our special cams and tune to get the torque back". But it never did get back to standard levels of torque with those extras! It was primarily designed for forced induction, but losing that much torque didn't win them many customers iirc.
I think the same is true of HPA's own TFSI intake. "Yeah, you need our tune otherwise it won't run properly".
Seems to be a bit of a theme with the Americans. They go bigger and better on the flow but it royally messes with the engine dynamics, so they have to then mess around with the ECU to try and get you back to where you started with the standard manifold :grin:
So erm, yeah, squirt the meth into the standard intake!

Some good info in here chaps. Glad I started the thread. Keep it coming!

I'm really interested in the possibilities of a wm kit...intake charge temperature reduction and valve cleaning are attractive.
One thing I'm not understanding here...
We are/would generally run water-meth?
The BMW story linked here, and elsewhere, seems to be plain water.
And then there is the ethanol/methanol/propanol "blend" talked about above also.
Can someone enlighten me please?

As far as I understand it (and someone more knowledgeable should chip in) water alone simply cools the charge and slows combustion, whereas methanol actively increases the octane level too. That's a very basic explanation!
I think in the case of a production car it's far easier to use water alone. Although time will tell how that develops.
