Speaking of awesome turbo BBK-3B, i.e Blouch XTII is it: superb. It is perfect- say for someone having a 2.0 and wanting more but without the heavy tax of FP Red in spool.
Or 2.2/2.3 motor and best spool.

The HKS GT3 I've "met a guy" who had it, and it was as promised on HKS dyno sheets. It was slower spooling and had more on top.
It will make way more than 41lbs so it's weird to make it legal in 41lbs flow rate class.
But whateve.r


FYI: regarding your dyno 397 on Mustang.. please don't compare Mustang to Mustang. It is totally easy to calibrate it to anything.
Don't worry, Evo 9 turbo can only flow what it can, and citing a turbo making certain power is nothing without baseline.

That is WHY, I said, Evo 9 stock puts 215whp and all out on E85 Evo 9 could reach 375whp on this dyno...but this turbo will die sooner than later due to being pushed way hard.

So don't get hung up that you have some miracle child. Evo 9 turbo is what it is, and HKS is what it is, and that is irrespectable of dyno: dyno is measuring tool to measure.

The rules are worded a bit poorly because the HKS turbo example given is referencing the Subaru version, which is around 41lb/min (the compressor dimensions are very similar to an 18g). From what I've seen the evo version does not use the same compressor and turbine (may be wrong on that tho) so you'd still have to prove its legality, unless you're trying to exploit a word loophole.
