Because of the low back pressure limits of gasoline engines, the performance of a gasoline exhaust brake would not be substantial. Because the air intake in a gasoline engine is throttled and the compression ratio is much lower than in a diesel, the performance of a gasoline engine brake would also be insignificant. Because of this we do not offer any retarders for gasoline engines.

Jacobs Engine Brakes are designed for specific engine applications, and retarding performance will vary depending on several factors of the design. One thing that is common to all engine brakes is that retarding horsepower increases as engine RPM increases. Optimum performance of the engine brake is achieved near rated engine RPM. In general, the same things that affect positive power influence retarding power.

Typically, under good road conditions, the driver enables the retarder and selects a level of retarding with selector switches on the dash. To activate the brake, two more conditions must be met: clutch is engaged (or automatic transmission is in lock-up), and no fuel to the engine (foot off the pedal). Under these conditions, voltage is applied to the engine brake solenoids, and the brake is activated.

The federal government has required all vehicles manufactured since 1978 to meet noise requirements when delivered to the customer. Today, trucks are required to emit less than 80 dBa of noise when they drive by, as measured at 50 feet. So trucks have been required to meet noise requirements when they leave the dealership as new vehicles for quite some time. The real problem here is modified or defective exhaust systems.

Your idle speed adjustment screw is incorrectly tuned. When you apply full brakes, the carburetor opening must not be completely shut off. To adjust the engine's idle speed, see the engine tuning sheet that came with the engine or your kit. Click here if you have lost this tuning sheet. If adjusting the idle stop screw does not solve the problem, see below.

NO! You cannot burn it in a gasoline engine, it is a Diesel Fuel substitute & can only be ran in a compression based Diesel Engine. BioDiesel cannot be spark ignited. Absolutely not, BioDiesel is made in a chemical conversion process where vegetable oil, alcohol are chemically bonded under heat using lye as a catalyst. This chemical conversion process is called "Transesterification.

Jacobs Vehicle Systems is not developing an Engine Brake for these engines today. Typically engine brakes are applied to engines of 10.0-L displacement and higher. The Jacobs exhaust brake product is available for the Cummins B5.9, ISB, C8.3 and ISC engines. For more information about the Jacobs Exhaust Brakes for Cummins B and C engines, visit our Medium Duty Exhaust Brake Applications and Performance page, or our Exhaust Brakes for the Dodge Ram page.

No, Rislone Compression Repair is designed to only be used with conventional 4 stroke automobile engines.

There isn't one, but we will tell you our opinion based on our experiences and observations. We currently own, run and have dynoed the following: 21-24cc Echo, 21, 25, 28 & 32cc McCulloch, 22.5cc Zenoah G2D, G23LH, G23L, G23PUM, 22.5 & 25.6cc J&G top end and billet motor, 25 & 30cc Homelite, MS35 Equalizer, 36cc Quickdraw A4P Decked, MS 42cc Zenoah Compact, MS 60cc 2X Outlaw, 30cc Cobra/Enforcer/Prather. Most "bang for the buck"….

You should always remove the gasoline from the engine if you plan to store the unit in your basement or transport it in a vehicle. You should never store combustible materials in your home.

Because of the type of fuel as well as the design of the engine itself, a diesel engine operates at lower internal temperatures. This helps lengthen the lifespan of the engine block. In addition, there are no spark plugs and associated ignition parts, which reduces maintenance. A diesel engine also has fewer moving parts, which also helps increase engine life as well as reduce maintenance. And, diesel fuel is often less expensive at the pump than gasoline.

The estimate given by the manufacturer for the gasoline run time can be used for propane also because it is just that; an estimate or guess. Propane only has about 10% less Btu content than gasoline gallon-to-gallon, so the manufactures gasoline estimate will be very close for propane.

If you have a modern turbo-charged car, the exhaust and engine management are the two biggest limiting factors when it comes to making more power. In the case of an exhaust, the problem is restriction. Generally speaking, Auto Manufacturers are usually pretty conservative when it comes to their exhausts. They rarely put on an exhaust that is mandrel bent, and they will put on a muffler that keeps the noise to a minimum in the cabin, but is also pretty restrictive.

Air is taken in high through the remote intake "snorkel/intake staff" The exhaust is low and exits the engine in the opposite direction being towed. The engine fan, designed to cool the block, further creates an air buffer between the exhaust and the intake. Brownie's™ compressors are tested and meet the same grade air (E) required for scuba. Brownie's Third Lung™ furthers the detail by adding a DRY snorkel cap to the remote intake.

Yes, the new manual transmission 24-valve engine was designed with the exhaust brake in mind. Replacement of the exhaust valve springs will not be required as it was on some models of the previous style engine. (Please note: Current 12-valve-compatible E Brakes designed for '89-'98 model Dodge Rams should not be installed on '98 and later 24-valve electronic engines. Doing so can cause serious damage to the engine.

The "Classic" 427SC had competition pipes under the doors. Being real race cars, the finish was not particularly important, and they were typically painted with a simple high temperature paint - usually white (see the top picture), sometimes black. No gloss, and the paint didn't stand up very well. On the other hand, a simple spray can would rejuvenate the pipes. Some people, wanting a more durable finish, have there pipes ceramic coated. Central CT Coatings does ours.

SynLube™ Lube-4-Life ? meets the API SL, SJ, SH & SG service classification, which covers most gasoline automobile engines. And is already designed to exceed future proposed specifications. SynLube™ Lube-4-Life ? is not recommended for two-stroke-cycle engines where oil is mixed with fuel.

Both gasoline and diesel fuels are mixtures of hundreds of different hydrocarbons which differ in their chemical structure and composition. During the combustion process encountered in gasoline and diesel engines, these various hydrocarbon molecules mix with oxygen supplied by the air and compete for the combustion reactions in which carbon is converted to carbon dioxide and hydrogen is converted to water.

In 2-stroke engines the lubricating oil is directly mixed with gasoline by adding it into the fuel tank. DurAlt? FC can be added to either the fuel tank of the 2-stroke engine (just like in the case of a 4-stroke engine) or it can be added to the oil prior to mixing into the gasoline.
