I thought you guys might be interested in this dyno data. This is from a client that I recently completing the final programming of his custom chip. The build of this motor was originally inspired by reading about Ralph's twin plug 3.5 write-up in European Car , although with some different build specs. The primary difference on this motor compared to Ralph's are more aggressive camshafts better suited for his track use - note the hp does not fall off above 6200 as much. This run was done with a street style sport muffer - just like Ralphs. Using the typical assumed 15% drivetrain loss, the crank hp approximates to 292 hp.
