You could try going even tighter on plug gap, might tell you if coil packs are failing. Also, I wouldn't want to run that hot a plug on FI. Go to a 6. NGKs getter colder as the number goes up. How about posting or sending a picture of the wonder widget?

Douglas Sent: Sunday, July 12, 2009 8:00 AM To: Miata List Power Subject: JR supercharger issues A friend has a hotside JR supercharger that was installed on the car when she bought it. I am not really familiar with all the available JR goodies available, so I'm not sure what all is installed. The SC has the standard pulley and the car makes abou 5-7 pounds of boost. Behind the passenger seat is a brain box that has a vacuum line feeding it and a knob. I'm trying to identify this hardware so I can get some documentation. The car recently began hesitating and missing in boost. I found that the coil pack was loose and replaced the plugs and wires. The problem persists but is greatly reduced. I even went with a 0.035 spark plug gap when installing the new plugs and used a 5 heat range plug. Any ideas about what this hardware behind the seat is, or what to check next? _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
