How a Dyno Works

We’re going to quote DynoJet directly to explain how the machine works, since paraphrasing would only do you an injustice. “Power, in mechanical terms, is the ability to accomplish a specified amount of work in a given amount of time. By definition, one horsepower is equal to applying a 550-pound force through a distance of one foot in one second. In everyday terms, it would take one HP to raise a 550-pound weight up one foot in one second. So to measure horsepower, we need to know force (in pounds) and velocity (in feet per second). DynoJet’s inertia dynamometer measures power just in this way. The dyno calculates velocity by measuring the time it takes to rotate the heavy steel drum one turn. The dyno measures force at the surface of the drum by indirectly measuring the drum’s acceleration. Acceleration is simply the difference in velocity at the surface of the drum from one revolution to the next. The force applied to the drum is calculated from acceleration using Newton’s 2nd law, F=MA, (F)orce equals (M)ass times (A)cceleration. Power is coupled to the drum by friction developed between the driving tire of the vehicle and the knurled steel surface on the drum of the dynamometer.”

Calculating Torque

“When an object rotates around a point, the object’s speed of rotation depends on both an applied force and the moment arm. The moment arm is the distance from the point of rotation to where the force is being applied. Torque is the product of the force and the moment arm. For example think about trying to spin a drum by wrapping a rope around the drum and then pulling on the rope. If the rope is wrapped around a drum of one-foot radius and pulled with 550 pounds of force, the resulting torque is 550 foot-pounds. The torque on the dyno’s drum can be calculated by multiplying the force applied by the drum’s radius. However, engine torque is not equal to the dyno’s drum torque because the gearing through the drivetrain changes the moment arm. The change in the moment arm is proportional to the ratio of engine speed to drum speed. Therefore, tachometer readings are necessary to calculate and display engine torque.”

FAQ’s concerning Billy Boat Exhaust Systems, Names and Tonal Evaluations

How do I make a decision on the type of sound I want for my Corvette Exhaust System?

 

Since an exhaust sound is heard somewhat differently by each person, we have attempted to classify all BBE exhaust notes by a Style Name that identifies the attributes of that specific system.

 

     FUSION Exhaust - NPP Controlled Bi-Modal - Aggressive when Open, Mild when Closed.

     PRT Exhaust - Aggressive Sound at Wide-Open-Throttle, Mild sound at cruise.

     BULLET Exhaust -  Aggressive Sound

 

 

What is a Fusion Exhaust System?

 

Billy Boat Exhaust has designed a Fusion NO-DRONE exhaust for the factory NPP and the non-NPP Corvettes. On C6 Corvettes with the NPP option, the butterfly valve in the exhaust is controlled by

the ECU. The valve opens based on RPM and throttle position. The expertise at BBE is getting the “tone” right for your Corvette, and we think they nailed this one.

 

Even in the closed position, the tone is deeper, louder, and more aggressive. Open the valves and the overall volume and tone increases to the point heads will turn when you drive up.

 

Add our 648-042 conversion control kit for Corvette models without factory NPP controls. The kits comes complete with all the wiring, remote switch, vacuum line, vacuum accumulator, and vacuum switch needed for installation. Can only be ordered with Fusion Exhaust Systems.

 

 

What is a PRT Exhaust System?

 

The Billy Boat Exhaust PRT C6 exhaust system is the latest control in Performance Resonance Technology from BBE. Completely redesigned and reengineered for the C6, the system is simple in design, though more complex in theory.

 

You can now have a mellow NO-DRONE sound at cruising speeds and a sport note when you’re tearing up the streets. It allows true straight through exhaust passage under aggressive driving conditions, though a mellow sound is emitted at cruising speeds thanks to the unique Purge Chamber.

 

Designed especially for the automatic, paddle shift and cars with headers, this Billy Boat Exhaust PRT system works purely on physics and adrenaline.

 

Increases of 15 hp and 14 ft lbs over stock.

 

 

What is the meaning of a Bullet Exhaust System?

 

Billy Boat Exhaust has created a deep, healthy exhaust note at low RPMs with an assertive muscle car roar on acceleration. Not for the weak at heart, the Bullet Exhaust System has quickly become the industry standard for a deep, aggressive muscle car sound for Corvettes.

 

You can see up to 18 rear wheel horse power and 17 foot pounds of torque from the Bullet. Billy Boat Exhaust’s boldest tip style and configuration insures the Corvette will scream “muscle car”.

 

What is a Cat Back Exhaust System?

The term “Cat Back” can be defined as the section of the exhaust system that runs from the outlet of the catalytic converter to the exhaust tips. A cat back exhaust system usually includes the pipes from the converter to the mufflers, the mufflers, and the exhaust tips.

A cat back exhaust is typically made up of rear-pipes, resonators, mufflers and a “style” and size of muffler tips. Depending on your Corvette’s year, model and location of catalytic converters, it can also include a mid-pipe and or a X-pipe.

 

What is an Axle Back Exhaust System?

The term "Axle Back" or rear section exhaust implies the exhaust system is located behind your Corvettes rear axle.  Corvette Axle Back Exhaust Systems typically replace the factory rear exhaust pipes, rear mufflers and muffler tips with an improvement in overall sound and appearance.

If the stock cat's can flow a large amount of exhaust gas without creating too much restriction, adding an aftermarket  "Axle Back" exhaust system should offer a nice increase in horsepower.
