Engine - normal operating conditions

[Harley818]

After driving for a few days now, I have a couple questions for you......

What is the normal operating condition for the engine gauges?

water temp is around 185 - 207. Fans kick on at 207 deg F

Oil pressure - I am reading 10 - 20 psi at idle, (is this too low) and it ramps quickly to 90 - 100psi
Oil temp - around 180 - 200 F once warmed up

Fuel pressure - (measured inline after the pump) startup it sits around 45psi. jumps to about 100 when you accelerate, then back to 45. Is this normal?

I also have an intake air after the AWIC. the temp runs around 5 - 10 above ambient unless stuck in traffic or you turn it off and it gets heat soak. Once back on it quickly comes back down in a couple minutes if there is enough airflow.

Just wondering if I need to watch the oil pressure or fuel line pressure

Thanks for any help or suggestions.

Oil pressure should be around 25 at idle warm
oil temp is fine
fuel pressure should be at 43 with key on engine off, and then go up with boost in a 1:1 ratio, 10 psi boost should give you 53 psi of fuel pressure
AWIC is normal

Thanks Wayne that puts me at ease..... all is ok then.

one more question.

I originally had the Frozenboost blowoff valve installed. It was really noisy with the psssst. and whoosh...... couldn't even hear the exhaust.
I made an adapter flange and now have replaced with the 2002 Air to air blow off valve. this reduced the sound by 50% but its still a bit louder than I'd like.
Any other options to reduce a bit more?
I think its loud because of the cobb air intake which allows the sound to exit through the intake. stock subaru isn't that loud.
