interesting analysis. can't wait to see where you guys put the "sweet spot" of this TMIC. like you sorta said, you can't go "balls to the wall" due to space constraints, but you don't want a tiny TMIC that the 425hp guys are actually hindered by. but at the same time, where is the TMIC LGT market's sweet spot? not that I have facts, but I suspect most high horsepower applications go FMIC (maybe cause there's no TMIC that meets their needs, but I suspect several other reasons too), but then there are high PSI E85 lgt's too (so can't go too low). And on the other end, where is the point where a common LGT owner decides to get a new TMIC? stage 2+ and beyond? and then goes FMIC at stage 3+? business decision as much as an engineering decision. and is all limited by space.
can't wait to see what comes out the other end. I make these decisions a lot, but my customers are internal and thus are more specific and very few in number. don't envy your decision, but do envy what you get to work on and test.
