(In Z/28 Therapy)
|
On another note. I was just think about the aftermarket stuff. I was looking and one of yals avatars and I was think that some ones gonna come up with that Knightrider effect to insert in the Z06 scoop that is have on the front. Then I remember that they made that new Knightrider show and they used a Mustang? Is nothing sacred? Ewww.
Oh and don't think that there aren't some guys that like the pre-pro head lights and some one with eventually come up with an aftermarket set for those guys that like em. My problem... I'm very impatient. I want to buy this car like yesterday. I want this car so bad, I've got nightmares of getting to the dealership and Boss Hog was at the counter and he started laughing and he said....he said....they were all sold out.

I think you're referring to the deactivated cyllinders during V4 mode, right? If so...the valves are closed, so no air gets pulled in or pushed out after AFM kicks in. So those cyllinders wouldn't feel the boost(what little there would be*). The air in trapped in the cyllinder acts as a sort of spring - compensating for the power loss when the piston compresses it. *AFM will only activate at lower rpms, where the power of all 8 cyllinders isn't needed. At those engine speeds - very little, if any boost is being produced by any FI system. So I can't imagine any problems there.... I don't mean for any of this to come off condesending...I'm just assuming I know what you said in your post (the italicised). |

I think the valves would still have to open and close since the piston is moving in the cyliner. If the valves were to stay closed the piston would be bound in the cylinder and couldn't push air our or draw it in as needed. So, I can see some concern that air will still be forced into the cylinder but will not be burned and that may cause over presureisation of the dead cylinders. Ahh wait a minute. As I think about this GM would have had to already figure this out. In V4 mode if the valves are closed in the compression stroke that air in the dead cylinder has to go somewhere. GM must have a way to push what would other wise be trapped air out when the cyliner is inactive. So I think we're discussing a moot point. However I still think the pass through valve on the supercharger would allow AFM to operate normally on a blown engine. These valves are proven systems that have been in use for years to reduce the fuel consumption that superchargers cause. So I'm thinking whether you're in v8 or v4 mode the blower will vent whatever air isn't being used. and when a load is placed on the entire system everything should come to life in the correct way... Just my thoughts, Any one else?

I encourage you (and everybody else who wants to learn) to read this: it's everything GM's put out in regards to the L76 for the media, should they use it....which they don't.(unless you consider us an extension of the media. It explains in detail exactly how AFM works. LOMA, valvelifters, etc. Personally, I think it's very interesting...but I'm a grease-monky like that. http://www.camaro5.com/forums/showthread.php?t=1978 |

Actually all the valves are closed on the deactivated cylinders. You might think that it would stop the engine but it actually forces the air trapped in the cylinder to act as a spring for the piston which helps it go up and down with very little loss of energy. It would drag the engine down a lot more if the valves were left opened! "When loads are light, the E38 automatically closes both intake and exhaust valves for half of the cylinders and cuts fuel delivery to those four. The valves re-open to activate all cylinders when the driver demands brisk acceleration or full torque to move a load. The engine’s electronic throttle control (ETC) is used to balance torque following cylinder deactivation or reactivation. The transition takes less than 20 milliseconds, and can’t be detected by the driver." http://www.camaro5.com/forums/showthread.php?t=1978 |

Cool! Thanks for the explanation. So the bigger question is, will it work with a supercharger????

I cant really tell from the photos but are the door/windows like the ones on the 4thgen camaro where there is no frame around the window? Does this cause any problems down the road like leaking ...?
