You will have to do your own testing on your F22's to see what's possible. I have 450 at the wheels with no w/m on my F20, but with m/w you can up the ignition adv and get much more as it ups the octane and lowers charge temp, its vertually free power.

that's the thing; it clearly says 450bhp on the stats(brake HP- which is the same as Crank HP) and when you watch the dyno video at 1:25ish he clearly says "4xx at brake" not wheel so either it's a typo and the guy in the video misspoke(or doesn't know that BHP is a measure of hp at the crank) or this dyno isn't as impressive as everyone thinks it is.

so it gets me wondering if there is some reason why they never pushed it farther than that- 450 at the crank is only 10 or so more hp than the current KW kit is capable of. I mean, am I nuts or am I reading this correctly? because BHP is most certainly not WHP and that's a pretty big difference.
that works, so it should be able to push slightly more than a N1200?
I guess is what I'm saying is I would like to see someone make 450+ at the wheels before I go choosing this kit over an SOS kit- I'm not doubting the charger is capable of more(if what you're saying is accurate- and I have no reason to doubt that), just wondering why it is presented as if 450bhp is the most you can push? if that were the case then why everyone is getting all excited over 370-380whp? other than that this looks to be an awesome kit and I'm sure it's just a misunderstanding- I would love to hear the manufacturer chime in on this though.
my other question still stands- why is water/meth necissary at those power levels? isn't there and FMIC? don't smaller blowers push just as much power without meth? what's the difference? or is it just a safety/liability standpoint?

I am flying the BS flag 
on that stage 3 dyno chart. the most very basic of the formula to make the hp number based on tq is completely wrong on that chart.
without going too much into it, hp and tq have to cross over each other at exactly 5252 rpms. stage 3 kit shows it cross at 4200 rpm. it also shows the tq continue past the hp. if that were the case, the hp would've touched 460+ hp. someone needs to clarify.
