Yes... using 110 they are the right ones... The ones posted before were also the right ones... but not for our engines. Instead of looking up the EVO numbers, I just looked at the DSM spec sheet sitting on my hard drive.... much simpler and quicker in order to get the point across, considering I have stuff to do at work. They still were not correct even using DSM lobe seperation angle. You did the math on the opening and closing points @ 1mm and not advertised like I originally stated. The spec card you quoted is correct but your math on overlap and LSA is not...you posted lobe seperation angles in excess of 130 degrees and overlap in the single digits. :eek: Overlap using your centerlines and info on DSM cams: 264/264 -> {[(264+264)/4]-110}*2 = 44 degrees overlap 272/272 -> {[(272+272)/4]-105}*2 = 62 degrees overlap 264/272 -> {[(264+272)/4]-106}*2 = 56 degrees overalp 272/264 -> {[(272+264)/4]-110}*2 = 48 degrees overlap

Yes... my differential EXPLODED... so I need to get my original trans (synchro problem) fixed. BUT, if I can't find someone that is willing to work on an F35 MU3 Trans... then I think I am going to be stuck buying a new/used trans. :(
Either way... cams gotta go. |
back story.
the 264 intake and 272 exhaust dsm set up was to help the smaller turbo guys get more top end pull. also they wouldn't have to dick with the idle to prevent the idle surge issue and other things here and there. not as much power as a straight 272. a smidge more than a straight 264. i hate math. cereal. |

This is why I said to reduce the intake cam as reducing the exhaust cam duration limits top end airflow while still giving poor low end with the larger intake cam. With the exhaust side longer than the intake, you help uncompressed exhaust scavenge but still exhibit good low end torque since the higher duration intake cam that allows compressed air to ingest is not needed. With the HKS Evo grind the overlap would be the same on both cam setups no matter the combination. |

Eh, its good hearing those opinions though imo. What isn't needed is the insults when someone only "thinks" they are right or even if they are correct. I'll take a good discussion any day but when insults are relied upon to try to support an opinion I can't help but laugh.

witt. the cams of win :) |
witt you wouldn't happen to have a pic of the shims that were sent with your cams? I'd like to see it

Area47 tried having a set machined with a flange so they wouldn't slip but lifter-bore clearance inhibited their use. |

They are simply machine washers. Bates uses a similar technique.

Later on, I had a friend tell me that the official stopped me about 2 ft before the burnout box. So I'm thinking that either a roll pin just decided to fall out... or that I got WAY too much traction, which is what I think happened, considering how much VHT was on the ground from the Slick cars running for the previous 3 hours. https://www.cobaltss.net/forums/problems-service-maintenance-69/usmcfieldmp-vs-f35-tranny-107667/ Pics are in post...32 or something |

Looks familiar.

should!
well, not exactly. a few things in the pic are different. i was staring at the pic and trying to figure out where the 130 degree's came from ::shrugs:: |

For example, one person talks about valve overlap, the next person assumesyou mean lobe overlap, and gets all sandy vagina on you about it. :lol: It's shit like that, why I've deleted most of the technical stuff I've ever put on this forum. If people want to start making assumptions on my behalf, I'll stop posting stuff. The other thing, is when people get all hard headed about stuff, and when there's an alternative they, again, get all sandy vagina instead of asking people to explain.... then again, i can't really blame them... how many people will actually take the time out of their busy day to reply to a PM? So, fuck it... I'm down shifting into An0 mode, and gonna lurk and laugh for a bit.... answer a few PM's and stuff.... maybe while I'm lurking someone can post a how to for "keeping your cooter clean". :lol: |

F35 is actually a model number based off torque rating (350 newton*meters). The MU3 is an RPO code. Multiple transaxles can have the same model number but can also have different final drives, revisions, etc. The MU3 is an identifier on that specific type of transaxle and usually any further revisions or changes will be designated with a new RPO though this isn't always the case.
