Assembling a better performing exhaust system a carburation leaning is created: riders have to slightly improve the gas contribution and air in the engine to level the potentiality of the exhaust system to the gas requested by the engine.
In the last generation motorbikes when the original exhaust system is replaced by a more performing SC-Project model a better and quickier exhaust expulsion is obtained: it is appropriate to adeguate also Co, that is the value of carburation. Riders can reach this through the installation of an AFM unit which balances the gasoline input in the engine with the outgoing exhaust, which is best thanks to the new exhaust system in the only silencer version too.
SC-Project — factory with the leadership in the manufacture of motor biker exhaust system — is strongly settled in the race world and this guarantees the final customer the highest performance without compromises. All championships are directly followed. The experience and know how acquired in worldwide races together with several tests on test bench guarantee excellence both in race world and private world in the street.
Only companies with top level technologies and capabilities can be supplier of MotoGP teams, where the highest technical competences, a constant evolution and development are requested for the strongest and most competitive worldwide riders and teams.
This technology is then used to produce SC-Project exhaust systems for customers for normal road use, supplying a wide range of silencer models and complete exhaust systems. The partnership with important racing teams allows SC-Project to get a very important technical experience and to test the ultimate products and material.

Technology and excellence, with no compromise, that is our philosophy. COVID notice. Due to lock down we are working with only one staff on site, parcels are still being collected and deliveries being delivered. Please expect a slight delay during this time.
Before you go there, you must first understand how the system works, because performing a disable on an engine with worn active fuel management components may cause additional damage. The engine will operate on 8 cylinders in V8 mode during starting, idling, and medium or heavy throttle conditions.
When commanded ON, the engine control module ECM commands the AFM system to deactivate cylinders 1 and 7 on the left bank and cylinders 4 and 6 on the right bank. The valve lifters in these engines are fitted with spring loaded locking pins that connect the internal pin housing of the lifter to the outer housing. The housing contains a plunger that works with the pushrod. The housing contacts the camshaft lobe with a roller. During full V8 operation, the locking pins lock the pin housing and outer housing together so the AFM lifter work like and ordinary valve lifter.
That unlocks the pin housing from the outer housing. The outer housing moves with the cam profile while the pin housing remains stationary and does not operate the push rod. The ECM times cylinder deactivation on an intake stroke when the intake cam lobe is pushing the valve lifter up to open the intake valve against the force of the valve spring. The force exerted by the valve spring is acting on the side of the lifter locking pins, preventing them from moving until the intake valve has closed.
When cylinder deactivation is commanded ON, the exhaust valve for the deactivated cylinder is in the closed position, allowing the locking pins on the valve lifter to move immediately, and deactivate the exhaust valve. The capture of exhaust gases in the combustion chamber contributes to a reduction in oil consumption, noise and vibration levels, and exhaust emissions when operating in V4 mode.
However, the ignition system still provides high secondary voltage to the spark plugs and the spark still jumps the gap on the deactivated cylinders.
SC Project Exhaust MV Agusta F3 675 / 800 AFM Additional Power Unit
A valve lifter oil manifold assembly is bolted to the top of the engine block beneath the intake manifold. The oil manifold consists of 4 solenoids that are closed until activated by the ECM. Each solenoid allows pressurized oil to flow to the AFM valve lifters.
The system also includes an oil pressure relief valve in the oil pan to regulate engine oil pressure to the engine lubrication system and the oil manifold.
Power is provided to each of the four solenoids when the engine is running. The solenoid valves open, allowing pressurized oil into valve lifter oil manifold and into 8 vertical passages in the engine block lifter valley and to the valve lifter bores of the cylinders to be deactivated. When the ECM turns off the V4 mode, the ground connection is disabled and the solenoid valves. The remaining oil pressure is exhausts through the bleed passages of the valve lifter oil manifold and into the engine block lifter valley.
The housing of the oil manifold incorporates several oil bleed passages that continually purge trapped air from the manifold and engine block. To help control contamination within the active fuel management hydraulic system, a small replaceable oil filter is located in the valve lifter oil manifold oil inlet passage.
The oil pressure sensor monitors engine oil pressure and provides information to the ECM. First, if an AFM valve lifter has failed or is starting to fail, you are NOT a candidate for an active fuel management disable fix. What causes AFM valve lifters to fail:. When you add an AFM delete kit, the oil is no longer allowed to flow through the solenoids.
Visit FT Speed. For those of you that are unfamiliar, the SEMA Show is a trade-only event — meaning, if you aren't in the automotive industry, essentially, you can't attend.
Each year it draws an insane amount of attendees. Forthe number continues to grow, with an estimatedpeople in attendance. It's a collection of some of the most incredible vehicle builds in the country.
It's the debut event for thousands of innovative new products. It's probably the only place you can turn your head one way and see Ken Block, and turn it the other way and spot a modified wide-body Lamborghini. Because it already has such a sporty design, the Type R always draws attention, but some people can go over the top with modifications.
Luis' is tasteful — sporting a stock engine bay aside from the T akeda Momentum Cold Air Intake, with our performance-oriented Pro 5R air filter. Luis explained, "The SEMA crunch was pretty spot-on this year, with less than two months to get everything together. This is my sixth time attending the show, but my first year being a booth car and its been an amazing road to here.
With a raw aluminum or black powder coated finish available, several builds rocked their custom finish choices.
With plenty of celebrity autograph signings, seminars to attend, and of course incredible builds to see, there is no shortage of things to do. Finishing off this exhaust system, is a massive 4.

On race days, awards are given to the top 3 finishers in each class and the top novice rider. Points are tabulated towards Season Championships. Many classes also have contingency sponsorship programs available from various manufacturers, businesses and shops. Uribe came into the weekend leading all three of his championships, and had the overall title well within his grasp. He did, however, need to finish the Formula Pacific race within the top 20 and beat the incredibly consistent Jordan Edginton in Open GP.
With no track day event on Friday, the weekend was much more compact than usual, and the number of incidents on track Saturday morning reflected that. Campbell was airlifted to Chico, California, with multiple injuries, including a fractured shoulder, a fractured T1 vertebrae, as well as a lacerated kidney. At the time of writing, Campbell was still awaiting General meeting starts at pm and is open to all members.
As I understand it, the LT1 in the Corvette will have AFM cylinder de-activation in the auto trans, and new for this year in the manual trans as well A few sources speculate that putting the car in certain driving modes like Track will reduce how often AFM kicks in.
CAGS remains another story? I'd expect someone will come up with a hack in relatively short order for both the skip-shift and cylinder de-activation if desired. In one of his interviews, Tadge notes that a torque converter automatic transmission played really well with AFM. Or something to that effect. If it really is as transparent as they claim, I'm fine with the system in Eco mode or Wimp mode or whatever they want to call it. I believe it has to meet a set of parameters, RPM, speed, gear, etc Once we crack the code to the ECM, as many guys in the corvette world will want that off like the Camaro guys.
It will be more interesting how its done in the manual mode. OK, probably a little longer. But it'll happen pretty quickly I'm betting I believe he's talking about manual transmission. I could see it being difficult, does it turn off during a gear switch or rev match? Does it only turn off on downshifts, not upshifts, etc The same E92 or E95 PCM that will be used in the C7 has been used in Europe for over 2 years now and no one has been able to crack it It is not as easy as someone ripped off GM's security seed as the E38,E40 E67 or even older PCMs It now requires the PCM to act like a node client and pass security to a remote GM server for controller software updates and all this about how easy and how everyone is going to just start throwing mods at C7 it are in for a rude surprise.

How does corvette control the sounds in the exhaust when it goes from 8 to 4 and back up without making the driver wish for a stright 8 exhaust? My silverado can not use an after market exhaust because of this 8 to 4 when cruising.
Good question, dutch. How does AFM impact the exhaust? I have had Silverados that I put an after market exhaust on and if you were out driving and not in town the motor would go up and down in the RPM range.
The one sound clip that was on this site sounded pretty good and I was just wondering.
2016+ Camaro SS Cat-Back Exhaust Kits & Mufflers for Sale
Got it. They have integrated sound control valves in the exhaust system just ahead of the mufflers on each side. They are supposed to modulate the sound in four cylinder mode to make it more pleasing to the ear. How affective they will be is probably subjective, and will cause more controversy on the forums.
These are not to be confused with the valves in the muffler outlets that come with the dual mode NPP exhaust option. With NPP you will actually have four valves; two before the mufflers and two after the mufflers. All are now electric as opposed to the vacuum operated valves used with the previous NPP option.
