Default Re: E46 M3 WMI Design

Thank you guys, you've answered my main questions.

My last question is a thought I had recently about the gains from cooling the intake charge. Where I currently have the injectors planned to be installed there won't be much of an intake cooling effect as the majority of the water will be directly into the throttle bodies and introduced into the chamber (which is the intent). Would it be overkill to install two additional injectors at the bottom of my intake plenum (see picture in first post) to lightly mist the intake plenum surge tank which might be able to cool some of that turbulent air in that area?

I haven't been able to find much data on what an intake plenum surge tank really does so I'm not sure how the air truly flows in that lower portion but assuming the air swirls down there prior to entering the throttle bodies I imagine that would be an opportunity to cool the charge? I don't see any negatives to the concept but figure'd I'd ask the experts.


Thanks,


~Anthony
