I cant stress enough for all of the years and multiple cars I have been exposed too that there is no one answer that fits everyone, each system needs fine tuning and in some cases it can make or break the combo and peoples opinions about what is "crap" and what is good. WI generally gets a bad wrap from many "specialists" who honestly have no idea let alone qualifications.
This RX3 has been a classic case in point, many meetings and phone calls over months and finally the sweet spot is reached, its involves usually people doign things they are not sure of or even recommending as it takes a long time and many sample cases of cars to establish what does work in many environments be they dyno or the track
RX3, 28x9 tired, 13B powered.
C16 fuel
WI running 50/50 mix (cant tell you exact ratio)
37psi boost
= 730rwhp on a dynojet
8.32 seconds @ 162.37mph
engine been running for 8 meetings and over 30 dyno runs, still perfect. And making enough grunt now to break the gearbox 
Based off this real world proof, shipped out another WI kit today to a local competitor who learned of this
Moral is you really need to thoroughly test and research and develop your system and then be prepared to do some more, it is all too easy especially today in the realm of the interweb and one off articles to come to your own conclusion about what is right and what is wrong...... you don't need to believe me or Richard, just look at what was done in the ultimate reciprocating engines during the war. The stuff there puts what most of us do today to shame by a factor of 10.
