Where would you spray meth on this setup? Pre throttle bodies? Common plenum between the blowers(after the TBs)? Post blowers/pre intercooler? Why?

 

Not exactly sure what your lower manifold consists of but you get better cooling spraying post compressor.

 

Back when I was supercharged I always wanted to spray after the intercooler. I think you will get the best reduction in heat that way.

 

There is a common chamber under the blowers before the IC. I also thought it would be better to spray here rather than through the rotors, if you could get even distribution. Spoke to Julio last year and he suggested sticking with a "proven" pre TB setup. I have sprayed pre TB in the past on a MP112 and saw no change in IATs.

wow... this is the first time I have really seen the bowels of this monstrosity of a project. WTF

Anyway... if there was a way to confidently get the same amount of meth in each cyl spraying post IC I would do it.

 

I bought 8 meth nozzles to do a direct port setup for as even flow as I could get. Eventually after thinking about it I figured the best way to get an even flow to each cylinder was to inject E85 through the injector. I have done the flex fuel conversion and it is working great. pump gas all week long and put in E85 before I go to the track.

 

I'd be very very weary of 8 meth nozzles... getting even pressure to all 8 and assuring they all flow the same is a bigger problem than you may think. There are a lot of people who have tried it... most ended up with a melted piston.

 

I know this isnt related to the topic but do you have a build thread about this thing?

 

That is the reason I never finished it.

 

Never did put it all into a single build thread. My "urgent to do list" is always too long. If I ever get a chance I will put together a history thread on how it was built/rebuilt and morphed over time.
