I can agree to disagree that all centrifugal systems are alike (some with ball friction drive for example will develop absurdly high boost on lower RPMs at the cost of reliability and heat and lower max boost up top: ROTREX C38-81, check an E46 M3 AA with the old ROTREX supercharger, try to get a dyno, i wasn't able to get a good one from google).

Let's leave it at that so that we don't clog the thread here. If you want to discuss PM me your number, we'll talk on whatsapp and maybe get to be friends as well, after all, we all have Z4M and we're all wife swappers according to Clarkson TopGear.

ironZ4M: thanks bro for the dyno, you are very lucky to have the T1-521 ASA unit and you would have been luckier to have had the T1-522HP since you could have done upgrades in the future using this

I am going FI in a bit...
But I need to see another dyno.
I am skeptical.
If you go to Iron guys photobucket, he's got a drum of race gas....
Would love another example just in case.

Otherwise, for the level I am looking at, Gpower wins hands down.
