I am running an M45 SC with a single TB pre charger and with a dummy TB in the normal position. No intercooler. IAT sensor is currently pre the dummy TB. MS2 management. I intend installing a water injection system, where should I fit the spray nozzle, before or after the IAT?? I have posted in another place too, but it’s a bit quiet..

When I looked in to this a while back for my intercooled M45 setup I decided it was post intercooler and pre IAT... but it's kit dependent. You can build a setup to do what you want and inject where you want, and different locations do different things. Devils Own has a good write up on the options here: www.methanol-injection.co.uk/?route=information/information&information_id=27My main reason for not pursuing this further is that the install gets complicated because you don't want to be injecting meth/water all the time, as you'll run out, so it's TPS dependent, then you need it to switch maps for when you do run out, and you need warning lights etc... JDM Subaru Imprezas had a intercooler misting setup that had a tank with a level sensor in it so not difficult to do in theory but when you price it all up you'd be better off bang for buck going for Skuzzle's supercharger cams (and in your case an intercooler). Just my opinion mind

Thanks for that, I don’t intend having a complicated install, hopefully I will be able to turn the spray on and off when triggered by saying simple pressure switch. Haven’t dug into my MS yet, there may be something in the software that could control it.

Fitting an intercooler is pretty much fit & forget. Isn't water meth a more complicated solution ( ) to achieve the same result?

The end result (more power potential) is the same but different ways of achieving it. There are pros and cons to both. For example, no intercooler and water/meth injection will mean minimal pressure drop from the charger and amazing throttle response as the piping is so short. Meth also acts as an octane booster (as I understand it) so you can go a bit more aggressive on the timing. Intercoolers are much simpler technically but there are packaging issues. Typical intercooler pipework is a bit long for a supercharger creating pressure drop (I read somewhere that each 90 degree bend was worth 0.5psi) and reduced throttle response, and an over the rad setup usually means chopping the front up a bit. And cost. Personally I'd intercool simply because I know I can do it myself. The programming side of things is beyond me and I'd be totally at the mercy of a tuner.
