What temp should I run with the full 3.0L (return fuel rail)? I run upwards of 220F. I know that I am running hot, but how hot? Keep in mind that I am in PHX and it is like 115F outside with the A/C running. I have the fans coming on a bit more aggressively that stock and am also running a cooler thermostat... Should I be concerned? When does she melt down?



Uhhmmm..that can't be good...

"Depending on ECT the PCM can pull up to 80% timing.

ECT timing pull is -10 at 200, -20 at 220, -40 at 230, -60 at 254, & -80 (i.e. default for bad sensor or maxed reading)
Interpolate between the numbers
Fans kick on at 216 & 224 or -18% timing & - 22% timing respectively.
Stock curve has about 32 degrees of advance.
SVT curve almost 40 degrees.

That's just the straight timing pull. There are many multipliers based on temp via load & rpm as well.

That's probably 10 to maybe 20 HP & TQ lost. Hard to quantify since I've never dyno'd the power loss from losing the majority of your spark advance."
