    VAC doing a 4.4 liter S65 stroker kit

    I don't know why they haven't said anything about this. @Mike@VAC what's the deal? Quiet about something like this?

    Since it is a 4.4 liter sounds like they used the GTS crank and bore remained stock. That is just a guess though.

    Can't wait to see what this does on the dyno which it should be getting soon.

    I would love to see this thing with headwork and cams on the dyno.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    The owner doesn't want to disclose things. If i'm not mistaken it's sleeved too.

    Yes but this is a kit that can be applied to all S65's as I understand it?

    You mean it can be done without sleeves? Yes, sure. If it's the same engine that i'm aware of, it's going to be driven under heavy pressure all the time so VAC guys added sleeves just to keep things together.

    And BTW if i'm not mistaken BMW doesn't sell GTS crankshaft to the public unless you have a GTS. It's VAC's custom built crankshaft i believe.

    It likely shares the GTS specs though as the stroke seems to be the same. The GTS crank is probably overpriced anyway so you are right but this may be quite similar.

    Which Schrick cams are those? They have two stages as I recall. Doing cams with the stroker is a must to push the powerband back to the right. A lot of peak HP is left on the table without addressing the cams.

    Nice to see someone doing it, props!

    Edit: Oh, they have valve springs too??

    It's too late, I don't even have a finished first project.

    I got caught up in being the fastest and beating everyone down. I should have built my own GTS. I would be enjoying it right now fastest 1/4 mile time or not.

    Not sure where it will land (haven't done this exact combo before). We will be tuning with Pectel. It will be impressive for sure Click here to enlarge
