    hello to everyone not reading this
    did some more road tuning recently and the results are just starting to get positive as i ran 13.7 at 104.4 mph with another road tune, more work to do on the tune yet but at least i have a truetrac and set of 3.9 gears on the way now, and am searching for a decent stall converter for it. so possibly with those two done can pull 13 flat or maybe even high 12's. ideally would like to get below 12.5 as thats as fast as i have heard of an alloytec going. maybe cams? boost is now up around 12 pound and thinking #### it and wind it up :)

    hello all,
    just a further update to my last post. put the car on the dyno and went 234 rwkw and 627nm. however was running extremely rich due to a sensor error, so now thats corrected will modify the tune some more and see how i go. finished the diff build, just got to install it now and reset computer for new ratio. also talking to a performance shop about torque convertor install so hopefully get that done and get shift points altered at the same time. so hopefully i can get around the 110mph mark on the track when it's done.

    I got a VCM dyno tune, Catback exhaust, Mace manifold spacer and 3.46 gears when i got my SV6 a few years ago and it has run flawlessly. Nothing special but it goes ok and the 3.46 gears really help it around town.

    My understanding is that, since the CPR6 is tall, you will have trouble fitting a manifold spacer as well, without bulging the bonnet.
    A 12.5mm spacer might fit, but it will still be tight.
    If you have a strut brace, forget it.

    Timing chains performance?

    Looking to do chains on my 05 sv6 soon is there any performance mods apart from cams I can do while everything is apart? Is there any chain kits better than genuine?

    Yeah mate, some prices quoted have dropped (CPR6 for example I am pretty sure is $1400 or less now) and I don't think OTR's for the V6 are easy to find these days but it should still all be good.

    Over the radiator cool air intake. Not supposed to be much more effective than the 2 hole mod (thats what I did, and what I'd recommend) but some people seem to swear by it. If you have the cash to blow to find out for yourself you might be able to find one online.

    How many kms between major services? My VZ has done 250000, and ive just changed the oil and filters at home. But wondering about other things that are done at major services.

    Commodore VE V6 Alloytech
    I just bought the 20% Powerbond power pulley set from MACE for 329 AU currency. It fit my 2009 Pontiac g8 v6 which is to my knowledge equivalent to the Commodore VE Alloytec. It seems to have gained more kick but I have no dyno results which means no number data. Id say worth the upgrade if you have the cash.

    Hi, get in touch with these people in the USA. They have good gear for the GM V6 engines at very reasonable prices. I know this as I purchased an insulated inlet manifold gasket from them and it cost me less than the Australian insulated inlet gasket including postage.

    Intense Racing, 720 Corporate Blvd, Plain City OH, 43064-9251. Re Inlet Gasket for V6 ecotech engine. They do the alloytech parts as well. Also, I have no clue as to what the number above is. It was just included in the address details.

    Sorry, it might have been covered, but there is so much to read...
    Is there any bore kits available for the alloytec?
