What makes a car sound cammed?
The lope you hear at idle from a “cammed” engine is do to valve overlap which is unavoidable with an aggressive cam, basically at low rpm’s both valves are open at the same time which causes incomplete combustion which gives off that lovely smell we all love from the exhaust pipes..
How much HP does 93 octane tune add?
When switching from a 91 octane tune to a 93 octane tune you can expect to see an increase of 5 to 6 more horsepower on top of the gains you are already getting from an 87 octane Bama tune.
What gives a cam a rough idle?
simply put. Beside above, what makes a cam sound lumpy? The overlap of the exhaust valve closing and intake valve opening causes the engine to be inefficient at low speed which results in the lumpy idle. The closer the Lobe Seperation Angle the more the overlap, the more duration the more (typically) the overlap.
What is a ghost cam?
The ghost cam tunes just tighten the overlap between the intake and exhaust cams at idle to give the lumpy camshaft sound.
How much power does a cammed 5.3 make?
After installation of the cam, the 5.3L responded with peak power numbers of 467 hp at 6,600 rpm and 418 lb-ft of torque at 4,900 rpm. With no other changes, the cam swap improved the peak power output by 108 hp, with even greater gains coming at higher engine speeds.
Is a camshaft expensive to fix?
The camshaft controls how your engine takes in air. It generally won’t break unless you neglect your servicing and oil changes and let grime and dirt build up on the valves. A replacement camshaft is highly labour-intensive, so it can cost between $1,500 and $3,000.
What does it mean to Cam your car?
“Cammed” means that they put in a different camshaft. The sound changes because the cam is the heart of the engine. It dictates how much air is taken in and put out and for how long, to put it bluntly.
Does a cam add horsepower?
Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You’ll idle slightly rougher with a performance cam, but get a throaty rumble that’s desirable for some gearheads, depending on your vehicle.
What do cam numbers mean?
What do camshaft numbers mean? … The first two numbers are the degrees of opening being 210 for the intake and 218 degrees for the exhaust given normally at . 050 inch of lift. The next two numbers are the valve lift of intake and exhaust in thousands of an inch. The final number is the degrees of overlap.
What is mild cam?
A mild cam is usually a little bigger than the stock cam. Most of the “Mild” cams have just a bit of lope to them and will give you a bit more power than the stocker.
How much horsepower does a Bama tune add?
Keeping in mind that increases will vary by vehicle and modifications, here are some of the gains you can expect to see from a Bama Performance Tune with basic mods: 2011-2014 Shelby GT500 Mustangs have seen dyno proven gains of 30 RWHP and 35 ft-lb’s of Torque.
What causes cam lope?
What determines cam lope? Lope is a result of the intake and exhaust valves both being open at the same time. … Mild cams have little or no overlap at any valve opening that makes a difference. Hotter aftermarket type cams have a lot because it aids high RPM breathing.
What does a cam do?
A camshaft is a rotating object— usually made of metal— that contains pointed cams, which converts rotational motion to reciprocal motion. Camshafts are used in internal combustion engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers.
Is Ghost a cam tune?
Ghost Cam tunes utilize the Mustang’s Twin Independent Variable Cam Timing (TiVCT) to make the engine sound and feel race-ready. … 130 seconds have elapsed since the engine coolant temperature reached 170 °F (77 °C) while the engine is running.
What is a disadvantage of CAM?
Disadvantages of CAM. Fast and accurate production. Expensive to set up. Machines can run constantly on repetitive tasks. Needs a skilled workforce of engineers.
Can you run 87 octane on a 93 octane tune?
87 is the standard octane rating that most car engines are designed for. … The reason why you should never run a lower octane fuel on a vehicle tuned for higher octane fuel is because the tune has no way of detecting what fuel you are using and will continue to operate assuming you put in the correct fuel.
Can you run 93 octane on a 91 octane tune?
Never use a octane lower than what’s prescribed by the tune. … You may use a higher octane than prescribed by the tune. For example, running 93 Octane (R+M)/2 on a 91 Octane (R+M)/2 program is fine, and in some cases may offer a bump in performance.
Is a ghost cam tune bad?
There’s nothing wrong with a ghost cam tune, plenty of people running it with no problems. Unless you’re auto, then it’s probably not a good idea due to the effect it has on drivability.
Do I need a tune after cam swap?
is a tune really necessary after doing a just a cam swap if i don’t go to extreme on the cam? We picked up quite a bit of horsepower and torque just from custom tuning the engine with the stock cam, so yes, tuning is very necessary if you want to maximize your new cam’s potential.
How long does a cam swap take?
about 4-5 hoursShould take about 4-5 hours if you know what your doing. Might as well replace all the stock parts (timing chain, oil pump, pulley etc…) like mentioned since they all have to come off. Plus, its added security every time you nail the throttle.
Can a cam mess up your car?
Depending on the cam, it will not hurt nor shorten the lifespan of you vehicle…… only the driver and his/her driving habits can do that. My suggestion: If you want great gas mileage, buy a toyota or honda. If you want a fast fun performance car with decent gas mileage…. get the car dyno tuned.
