If don't plan on rivaling MattM, simple big ass A2A + e85 will do 99% of us just fine. I've hot lapped many times in a row at the track and not notice at all as times don't seem to drop at all.
When it comes these things, keeping it simple works best. Don't over complicate things. Just asking for trouble most times.
If plan on A2W, just run one big ass setup, big ice bucket setup, and be done. Ditch the crappy m90 IC. Its tiny ass compared to a true A2W intercooler.
BTW, fun fact. When I was doing my setup, I was wanting to twin charge. MattM and Zooomer both talked me out of it, as they said it tends to be a PITA to deal with, and that in the end
I'd go faster on just a single turbo. Basically back to the "keep it simple stupid" ... glad I did.
Btw, nice little pro/con I had seen in the past.. kinda goes with what people have told me in the past...
