    Ours has been OK in the low position. Drives nicely. It does randomly not want to come out of gear though. And Jon had some grinding shifting to 4th during the half mile races. It may need a custom slave cylinder, etc, to ultimately work 100%.

    That very small boost leak around the CP will not effect power at all, the turbo would just have to work a little harder to keep boost at target, but boost is only the reading of restriction through the motor, I am sure with that head you will make the same power with less boost then someone with a stock head, but if you think the dyno numbers are going to jump up once you put an oring in the charge pipe that's not gonna be the case.

    Yes its definitely nothing to complain about. Since you are a mechanical engineer at an engine manufacturing plant, can you answer me this question because VAC still has not given me an answer about it. I read somewhere on the forum and i cant remember where but someone had stated that using Port injection (MOTIV's Kit) with a smoothed out intake port Vs. one that creates more turbulence is going to create a problem in mixture. I dont know how much of this is true but if possible could you shed some light on the matter because i dont remember reading anything that was a solid answer.

    Prediction: Manziel doesn't win more than a dozen games in his NFL career. It's a 1 week sample size, but holy guacamole his tape from last week is BAD. There are some fundamental flaws in his game that are going to lead to disastrous results. Like damn, that was gross.

    I'm not exactly sure what you're trying to say but I can tell you that for what all is involved in machining the VAC ST3 head, it is an absolute bargain. I can fully understand the concern people have with how things "look" to the naked eye, like how the intake ports look like they have "tons of meat" left and that they do not look polished but what they don't understand is how the "blueprinting" process is set up. I spent several hours on the phone with Tony@VAC, who is the owner and head machinist, discussing this very topic before and throughout the entire ordeal. Being that I am a mechanical engineer for the Toyota Engine Plant in Huntsville, AL, I understood and can fully appreciate and respect VACs machining processes. The flow data and dyno results, although currently compromised, have spoken to the quality and craftsmanship of this head. A 25% average increase in flow across the band is hardly anything to scoff at. Anyway, sorry for the tangent and good luck with your heads.

    looking at these pictures im starting to get a little sketched out about how much i paid for this to be done on my head. Im deff going to be getting some pictures taken before it leaves their machine shop. Website states "Meticulous full Port and Polish Work to enhance all performance characteristics" yet i see no parts of the head that look polished. I dont have many photos of these 6.1 heads but look at the combustion area of the head and compare it to the one of the VAC head. The attention to detail from what i see in the pictures of the VAC head vs. the heads ive installed is not comforting. A machine shop here in houston sells these srt8 heads for the same price as VAC yet there was more work done on the 2 heads than a single 6 cylinder head. This shop does heads for hennessey and many other well known shops and cars in the performance market so its not like they are just some hole in the wall trying to make a name. BTW what looks like scratches in the picture is just from the tape. This was right after we unwrapped them before cleaning and install. I know that the combustion area doesnt have to be mirror finished but come on that looks like it was just sandblasted

    How did you fix your issue? Or did you go back to a single disc?

    Mine had the same issue in both positions. Going the high position will cause more issues including preload on the PP. Best to contact the vendor and get their commendation.

    That is exactly why I wanted to check it out. If you think about high end wheels or wide body kits, those get changed all the time and cost more than these single kits! Lol You know it! I think it just might depend on what you're looking for. The two are totally different designs and I think they will both have some distinct differences in power delivery and drivability. We shall see though. I do think it will be a very responsive and stealthy kit for such a large turbo.

    Don't apologize for your car. It is an awesome drive, you'll enjoy it a lot, trust me. And highly moddable by now :) Long start up cranks are a telltale sign for a HPFP problem, long before you start experiencing drivability issues. The pump can no longer hold the pressure, and it gets worse and worse until it ends up where you are now. Put the JB4 in map0 and have the HPFP replaced. With some luck you'll even get a coulance discount at the dealer's.

    This looks like a beautifully manufactured kit. Congrats. A bit confused with your argumenting about buying this when you already have the FFTEC kit, but hey, it's your money, and we get to learn your findings first hand so it's all good from where I'm sitting :) Have fun!
