Satisfied with the performance... Satisfied with the performance of the engine, Mark Erney switched over to the customer's Demon 850-cfm carburetor. The tune that was in the carburetor was for the engine combo prior to the upgrades. As expected, it was found to be too lean, and the power dropped to 456.5 hp (ignore the jet numbers handwritten on the carb float bowls). | Test 2 | | Notes: Speed Demon 850, No. 88/94 jets, 36 deg timing | | RPM | Corr.
