    Hi guys.
    My lack of A/C on my VE V8 last week lead me to discover a whole can of worms regarding genuine Holden twin pulley conversion brackets that are now obsolete, as well as faulty harmonic balancers. Firstly, I wondered how a second idler pulley could cause a belt to stay in place where a single one wouldn't, and then after I refitted the A/C belt, I discovered my balancer wobble...
    I'm reading a number of various opinions regarding the under driven pulley kits from Powerbond and whether they're worth the extra money (although not that much more than a genuine replacement balancer, which has no guarantee of not wobbling either...). For a car that's stock for now (but not necessarily driven gently) but possibly a cam and exhaust package in the future, my concerns are the already fragile battery at idle (the Sportwagons only get a 6cyl. battery), so do I go for the 25% kit, the 10% U/D balancer, or the HB1117-N standard replacement?

    Bugger :(

    Generally put, underdrive balancers from a performance aspect do help out with improving driveability, however they can also be problematic as well.

    This is because if the auxiliaries which are being driven by the balancer aren't in perfect condition, these problems/deficiencies are more likely to show when an underdrive balancer is installed. For arguments sake, if your alternator is on it's way out or your battery is old, running an underdrive balancer may be enough to render them useless in their current degraded state.

    Also if you live in very high temperature climates and do lots of stop start driving then I wouldn't recommend this mod with the factory cooling system

    Given the information above, it should be able to help you decide which balancer to go with. For the record, I don't believe that Powerbond make a 10% underdriven balancer any more.

    "Also, do you guys sell the ARP bolt to suit?"
    We don't sell ARP crank balancer bolts at this point in time.

    Hope this helps.

    If you have any more questions please don't hesitate to ask

    Hey nice products guys,

    Im interested in the ls1 1.9 ratio rockers, but im also looking at adding a cam. If a cam is designed for high ratio rockers, will they be ok to use. The cam is Comp cams XR273HR, it only has a max lift of .53/.534, and states it likes high ratio rockers. I have calculated the max lift after the 1.9 rockers are fitted is .594. ill be adding pac performance valve springs which are rated to .625 lift. Any advice?

    "Hey nice products guys,"
    Thank you.

    Given you have an LS1, adding our rockers to a cam specifically designed to run with them along with appropriately rated valve springs won't be an issue. Given the combination of components you've suggested, they'll all reliably work well together.

    If you have any questions please don't hesitate to ask

    Kindest Regards,

    Hey mate,

    The stock CAI use a 3" filter.

    You're probably better off just buying the enclosure without the pod filter and then buy your own 4" pod filter and some ducting to suit.

    Thanks mate.
    I will have to get some ducting and custom make it to fit.
    Still up in the air as to whether to stick with the VCM OTR, or go for the Mace CAI.
    Although, as they say in the classics....A change is as good as a holiday.

    After doing a bit of research it seems as though that cam is compatible with high ratio rockers. This is stated in the following link:

    http://www.sho-mespeed.com/index.ph...224-lift-530-534-lsa-112/category_pathway-718

    I did also notice this thread in the commodore forum which is right down your ally:

    http://forums.justcommodores.com.au...ication/223998-ls1-1-9-rockers-small-cam.html

    It seems as though, as long the PAC springs have a max lift of .625 and not a coil bind height of .625, then the set-up you've just mentioned should work a treat.
