I'm saying that it has more potential for sure. They may have the same exterior dimensions (exducer & inducer) however the aero is different. The billet 67 wheel is cut closer to the shaft because it is inherently more strong than a cast wheel, which allows more surface area (longer blades)

AWDMotorsports made 920awhp on an evo and billet 67mm turbo. I don't know what the max power ever had on a standard T04R turbo is, but by going by compressor maps, it would never come close to these levels. Only issue I can see is that they made that power around nearly 50psi boost, rotaries would almost never see that kind of boost. So, it'll be interesting to see what kind of power it maxes out at around 25-30 psi

Scorpion do you sell Precision turbos?

No, Ive been using them for a long time so Im very familiar with them.

Exaggerated claims would be considered hype. Proven results are not hype, they are fact. When the turbo was first used, do you think people asked for a compressor map to prove they worked?
