My oil temps for those pulls were around 200-205 F. My peak track oil temps hit 245 F. I'd love to log pulls with those kind of oil temps, but not sure how I'd get them that high on the street.  |
I dont want to sound like I'm condoning illegal activities, but do scout the area for police and other traffic before you do stuff like that. Safety first, you know. lol
I'm curious to see what kind of maf voltages you are hitting with the setup. It looks like with the UEL setup and cam timing you can still run a lot of ignition advance at the very top end past 6000rpm. From experience, I know that colder IAT's will register higher maf voltage compared to warmer IAT's. (typically higher maf v = more whp) Though I'm not sure if that just how the maf sensor reacts to different temps or if it's because of the denser air charge at lower temps and the maf sensor reading is accurately reflecting the increased air flow at lower temps.
