This sound happens once the engine has been shut off for about 45 min to an hour and when the engine is some what warm. then after about a min or so it stops making the sound on its own. doesnt matter if a/c or heater is on/off. please help if you can!

Not trying to be a smartass, but I'd have to say "engine". That's the only thing I hear on your vid. Could just be my old ears, though.

Looks like valvetrain not having enough lubrication at start up after sitting for awhile....

What oil are you using? weight?

I can hear it loud and clear.

i use amsoil 5-30w and the sound stops after the first little rev of the engine its kinda like a humming sound????... it goes away after the first rev then its just the sound of the engine.

I'm sure I have the same sound that you do. I'm also convinced it's the A.I.R. pump doing its thing, as well as spinning its way into failure.

Wait...do you even have an A.I.R. pump?

My car used to make that sound! People said it sounds like a spaceship. It's probably related to the AIR pump. Just rip that **** out and it'll go away. and how are you making 400hp with just bolt ons?

I see the hose for the AIR pump in the vid... im going to assume he still has the pump also.

Unplug the pump and see if it still makes the noise. It can be reached via the access hatch under the car in the front driver side. 2 bolts hold the access hatch closed. Just know the SES will turn on if you leave it unplugged... but it wont hurt anything.

its the SLP 400hp package on the car so the engine is rated at 400 not rwhp but im going to go with a 222/226 cam and the guys at EPS says i should have aroung 400 to 410rwhp after the swap so in about a month or two after i order and install il have it tuned on the dyno and post up the print out of the dyno..
