Previous version of Bi made 655whp on 93 on a stock engine S55. Since then we made minor changes to compressor specs and profile without any increase in lag or reduction in transient response, which is the current production version that is on the built engine car. This current version Bi also flows more lbs/min than the previous version. So, meeting the goals of 600whp+ on 91 octane would be a very easy task for the Bi.
