    • Active Autowerke 2013 M3 S65 V8 potential Supercharger Line Up Testing - Rotrex C38-91 supercharger 9.5 psi + meth 93 octane dyno on stock internals

      BimmerBoost members, over the last couple of weeks we have been testing the Rotrex 91 trim on our stock engine shop car. So far our findings have been very promising. The biggest thing we have noticed is a large increase in efficiency, the blower makes the same if not more power running lower boost pressures with a marked difference in flow to redline. As of right now nothing is set in stone and things may change with additional long term testing.

      Here are the numbers running the rotrex on our Dct shop car : Stock engine- no cats- Dct-93 oct


      Mustang Dyno-

      Level 3- 539 Whp 356 wtq (9.5 Psi + Meth)
      Level 2- 495 Whp 325 wtq (8 psi No Meth)
      Level 1- 431 Whp 283 wtq (6 Psi No Meth) 20'' Wheels

      Dyno jet using conversion- Typical Dynojet Comparison 10%

      Level 3- 593 whp 392 wtq
      Level 2- 545 whp 358 wtq
      Level 1- 474 whp 311 wtq

        Great numbers, nothing's broke at 9.5psi on stock internals/compression though?

        Power and heat is the problem not psi.

        It's a 92 it has the same wheel as the 91 but a little larger cover.

        It's extremely impressive how well this engine responds to small increases in boost - or boost in general. Looks like a good option for a blower to me.
