Thread: VR6 cams

  1. #1

    VR6 cams

    Before anyone flames me, yes I have done a search! But reason for this thread was if anything has changed/opinions lately

    So what’s the best cams to use or consider on a stock VR for street use. With full decat exhaust and possibly BMC CDA

    I have shortlisted the following from research

    - schimmel 263
    - autotech 262
    - Schrick 268

    Ideally don’t want to touch the valve springs.

    Shimmels are apparently the best of the bunch giving gains across the range.. they run fine on stock springs.

    Jim Bowen is also looking for a set... could be worth ringing Vince at Stealth and staking an interest, they might speed the order up.

    Schimmel 263's are the ones to get. Could be worth seeing what Vince says. Last time i enquired he said he would order some if there was demand, but i've no idea how long that might take, Could imagine it taking into the new year.
    Just like a golf................But better!!!

    263s for standard engines and 268s for engines with Schrick VGis or pierberg VSRs according to Stealth via Kev Bacon from a few years ago.

    I've never seen anyone flamed here for asking questions, we all share what we know to anyone who asks. This forums search is notoriously poor.

    I’d be interested in a set of 263’s or 268’s if I ever get round to fitting my schrick.

    What is the reasoning behind needing 268s with a VGI or VSR? Both are designed to run with standard cams. I always thought that SP263s were the bes all round option for a standard engine - maybe he was referring to forced induction applications?

    The 268's are designed to take over once the Shrick Manifold is coming off song as such higher up the range... Speaking with Vince the 263's are the best all rounders... I have a Shrick manifold but still went for the 263's... Vince drew a nice graph and explained it all whilst I was there and they seemed the best to me.

    Ah, ok. 263s with a remap is what I am planning for myself eventually - if there's a group buy in the offing I'm definitely in.

    Petty much that, the Schrick fills the hole on the power curve usually weakened by the longer duration cams. For a road engine its better to view the area underneath the power curve rather than max power at XXXXRPM
