Their site says it's due out Feb 2011. According to what Lonnie Houde posted a while ago, it's supposed to displace 12.8 liters compared to the PSI C rotor's 7.4 liters. During dyno testing the DMPE made 28psi more than the C rotor at the same overdrive with lower outlet temps. 80-82psi at 9000rpm versus 52psi for the C rotor. It should be a monster if/when it's released. Anyone have any inside info?
