It will, but I haven't had a WBO2 in the car until this last race.... Usually we just ready plugs as chasing an AF "number" with a NO2 car can get you in trouble. However, I bought an NGK Powerdex AFX WBO2 used from a customer of ours who is upgrading. I wanted to see just where everything was at and mostly use it to see how good my carb was at part throttle under light loads like in the pit and return road... because my plugs looked absolutely horrible. On my test hit Sat, the display was pegged at 9.00 the entire pass... Which is the lowest it will read. Totally explains the plugs looking horrible because the carb is pretty good.... 14.1 at idle and never gets richer than 12.5 at part throttle - unless you hit the accelerator pump hard. A chassis dyno is possible but on a 1100+HP engine the acceleration rate is so much faster than at the track I don't know how much useable data I would have afterwards. Will |
