Grinding noise coming from the engine bay when hard accelerating at 5-6k RPM

[crash68]

@SugaryClapz is the exhaust stock or has it been replaced? If so what on the truck?

I know @Wild one may have ran a Hemi under hard acceleration once or twice, maybe he'll chime in.

I'm not even sure what he's talking about,as his video's leave alot to be desired.Maybe if he ran it up through a couple gears it'd be easier to hear what he's referring to.

As mentioned above, a good, free and easy test would be to look at the motor mounts. At least determine if there seems to be a problem there or not:


1) Open truck hood, Start truck, look at top of engine between hood and lower windshield

2) Hold foot firmly on the brake pedal, put truck into D (keep an eye on engine).

3) Give the accelerator some 'gas' (foot still firm on brake), and see if the engine rocks more than, say, and inch.

4) Then try the same test but this time putting the transmission in Reverse.

5) Keep foot firmly on brake pedal. Don't let the truck lurch or move. Make sure no people are around truck.

If a motor mount is 'bad' or 'failed' an engine will generally lift UP quite a ways.

You also might be hearing nasty harmonics brought on by air rushing through the air tube on it's way to the engine. Are you running a cold air kit or non stock air system?

Never heard that before, but I do get a nice whistle when I hammer down. Could the noise you hear be the switch from Eco to Giddyup?

Could be a waterpump, alternator, AC compressor pulley or tensioner bearing is going bad. Pop the serpentine belt off and spin everything. Also driveshaft u joints, axle cv joints could be the problem although they typically cause a vibration.

I am running S&B Dry filter cold air intake, I did the test and the engine does not move.

I don’t think so because I put in manual 6 gear and it gets rid of eco.
