I just got my defi link gauges hooked up and I'm not sure if my motor is running normal under the numbers I got from my gauges.
Since I was not able to search such a thread, I hope that I could gather some gauge readings here with different setups.
Here's mine:
stock s14 sr20 w/ stock exhaust
(except tomei manifold, greddy oil pan and s15 smic core)
defi link gauges: boost, egt, oil pressure, "oil temp"(not set up yet)
*egt sensor mounted on dp, half an inch next to turbo
hwy cruising 65mph:
egt: 1100 F+
oil pressure: 70 psi
idle:
egt: 800 F-
oil pressure: 20 psi (after warmed)
vacuum: -60kpa (-13psi)
under 10psi boost
egt: 1400 F+
under 14psi
egt: 1500 F+ (full throttle at 7k rpm)
Do these numbers seem normal? I think mine is running lean at high end and becomes too hot 1500 F at 14psi. My friend's evo never go above 1400 F even under boost.
I heard at 1500 F, it is enough to melt pistons. Is the temperature at exhaust manifold/dp different from engine internal? Does it get hotter when the air gets outside of the engine?
what readings you guys have?
