The reason you use 5W20 for the 57 is due to the MDS and thier lifters. Machine Design Editorial CommentMay 4 2000When I first learned to drive our family had a variety of cars and pickup trucks all.
You are hearing your voice vibrating within your skull throat and inner ear.
Why hemi sounds deeper. Here are the two most likely reasons behind the 57 Hemi tick. Broken or Loose Exhaust Manifold Bolts. Broken or loose exhaust manifold bolts are the most common reason behind the ticking noise.
What happens is the long exhaust manifold starts to warp due to heat cycles and pulls on the manifold suds and eventually breaks them off. All rotary car engines change pitch at higher RPMs more pistons are used low RPMs dont use all the pistons higher torque means more rotations and more rotations means different sound because of change in airpressure rotation speed is higher than speed the air is pushed out from the chamber causing buildup so pitch changes plus exhaust also plays a. Even though its chambered it still gets a little deeper sounding over time.
Also as your catalytic converters get thinner it causes the exhaust to get a bit louder You must log in or register to reply here. Just like a farmer services his cows. Hes blowing smoke up your a by telling you its normal or that its because its a hemi.
You probably do have a bad lifter bad cam or other valvetrain problem. Could be something else too - a rod bearing problem a wrist pin problem or excessive piston clearence. The exhaust and intake valves on the Hemi might also be the cause of the occurrence of the ticking sound.
The valve tapping may arise due to a variety of reasons. The valve tapping may arise due to a variety of reasons. Well we just got the new Flowmaster systems installed on both Hemis.
Man they sound GREAT. Of course now we have to figure out what to do with these HUGE stock ones. I believe its the combustion chamber that causes the difference in sound.
The Hemi has a distinct sound. A friend of mine has a 56 354 Chrysler Hemi in a 33 Plymouth and it sounds very similar to my Challenger albeit much louder due to headers and no cats primarily. Even slight variations in similar designs will cause a unique tone.
Most of all Hemi-Sync products are designed to aid you in your journey to wellbeing. Hemi-Sync was founded by Robert Monroe in 1953 when it was originally titled RAM Enterprises. Previously Bob worked in radio broadcasting and consequently was an expert in sounds and frequencies.
The mystery of why V8 engines sound so euphonious. Machine Design Editorial CommentMay 4 2000When I first learned to drive our family had a variety of cars and pickup trucks all. My 57L is a Durango they sound just like the Chargers do for an exhaust note albeit maybe a tad deeper because it is a little longer.
I tried straight pipes 1st but it was very raspy IMO. This option is if you want the same OEM sound but louder as it doesnt change the low end or like you said the bass to the overall sound. The larger oval body of the Hemi muffler helps produce the deeper sound.
The hemi style is considerably longer in length About 25 longer. PS On another note. I had to look up form a project I was working on the other day.
I could have sworn I heard the distinctive sound of a 68-70 Ford 428 Super Cobra Jet running down the road. Several things when you hear your voice. You are hearing your voice vibrating within your skull throat and inner ear.
The voice is vibrating parts of your throat jaw and sinus cavity. As your voice leaves your mouth it travels up the side. A bigger resonance box will produce a deeper sound too thats why trombones make deeper sounds than trumpets.
So whether we talk about strings or resonance box size the resulting sound will change. Your vocal cords are like a guitar string and your larynx is our resonance box. The Hemi pistons are a short skirt free-floating type and as with most high performance engines expand to ideal clearances when at operating temps to provide performance and efficiency.
The colder it is the more clearance there is so you hear piston slap. Hemi-Sync allows you to safely alter your brain waves with sound frequencies so you could achieve maximum focus relaxation and assertiveness. When you hear the multi-layered patterns of sound from the Hemi-Sync recordings your brain responds by producing a third sound a binaural beat that encourages the desired brain wave activity.
The Physics of Engine Notes Or. Why a Toyota V-6 and Porsche Flat-Six Sound So Different. The science of engine sounds.
Jan 1 2015 JUSTIN MACONOCHIE. All the music tracks and resources available on the Hemi-Sync website are based on numerous years of research on binaural beats. The way this concept works is that a sound played in your left ear when combined with another sound played in your right ear form a powerful vibrato.
This vibration is the binaural beating. Joined Sep 15 2008. Discussion Starter 6 Aug 26 2009.
The reason you use 5W20 for the 57 is due to the MDS and thier lifters. Use this oil and not 10W30. Unless you have your MDS removed with a stroker and the engine builder tells you to use something else.
You are watching. Why does the 57 hemi make a knocking noise Rt owners of 2011 up. My RT has actually a knocking sound when its cold upon startup however is extremely faint.
