    yes indeed Zok, my mates engine let go in a big way throwing a rod and kicking a huge hole out the side of the motor. Was fairly high strung for a standard crate L77 bottom end with good heads and cam, 2.3 maggie on 15psi, made 650 rwhp when manual and dropped to 580 when we converted it to th400. performance engines are a grey area when it comes to whos to blame. so many variables that are hard to pin point usually

    Tk is right and so is zok.

    The powercruise, if your pumped is an ass rapping session on cars.
    everyone is bouncing cranks, limiters are giing off. Tryers are frying and of top of that your racing in the process with your mates in the car with alot of ego.


    eg.. we have been entered in sydney for a few years now and the cars a tuff.
    mate finished his camaro show quality and said we will go once more for fun.
    Well the nitrous was connected and a small pill was up for show. Remember car was for show motor was a 500 big block crate motor gm.

    4 hours later we are on the way home.picking up..
    Slicks, laptops,bottle refriller, bigger pills, c16 drums. Spare tyres and every tool under the sun is in the ute.

    We are now heading back ready to take on the world.
    we ended with a torched piston, and a bearing on sunday, we started friday morning.

    point is powercruise is not a cruise session.

    I love holden turbo motors better than an ls1 turbo.
    Has more pride behind it lol
    ive grown to develop almost a hatred towards the ls based engines. haha. they are such an awesome platform but i just cant bring myself to go that way with this build. id rather beat these guys the hard way with the with the old plastic. gonna cost alot more but thats fine by me.

    My mates 355 went over 700rwhp on 9 psi with a gt42
    Can't tell you cam as Jakes performance secret. Don't go to big
    Haltech 2000 e85
    Remember bigger isn't always better.
    Like you said sell both your cranks and get a csr heat treated nitrate.
    Do it once do it properly with the motor, get it tough and very good oiling.

    yes i think i may go that way tokes, although i cringe at what the cost of a csr unit will be! haha. in regards to your earlier post, im not convinced on using justin at bye. ive seen 2 different cars with new motors that he built and tuned that didnt last very long. not saying its his fault or anything but i wont be utilizing his services on this build. a friend of mine has blown 2 or 3 motors with him now( 2 were std 6 ltrs and one was built with forgies ect), but it is a burnout car that receives little respect at all.

    paul Boz on the other hand is the bloke i will likely see for the engine work required.

    Of
    Mate that's the very first I've heard of this The Bloke Is always tuning Some Of the Toughest cars getting Around Perth And had cars At Powercruise that were frying tires and winning races..
    Street built seemed to of led the charge at Powercruise tho.
    Csr crank will be about 1600 that's cheaper than come billet etc and you won't need more than that for a turbo motor!
    Get your block sonic tested and make sure everything is perfect for the build, boz will sort you out mate if you do it properly and use the right people and parts it can live a happy life at Over 600rwhp
    I agree with the Ls motors, there cheap, they make big power but a properly built Holden v8 with boost will embarass a lot of these things and will keep the bores round for longer.

    $1600 is not bad at all.

    although not hung up on rwhp figures, 600rwhp is the ultimate goal on pump fuel, will be a big ask considering im running th400 and only 70mm turbo. holden motors tend to perform better in the hp vs hp compared to the ls engine. a good mate of mine had a t51r on his stock 215 vs gts and upset a few cars at powercruise years ago. some guys wouldn't believe that it was only making 415 rwhp and beating them in their higher rwhp setups.

    I'm hoping block sonic tests out ok as otherwise ive wasted some money. its already grouted and 4 bolted so would assume its been checked before doing that.

    BYE PERFORMANCE- The custom painted green ve that was at powercruise perth just gone was freshly built and tuned by justin and it locked up saturday before powerskid qualifying. was very impressive on the friday and sat morning. built 408 with single turbo. could have won the powerskid competition had it not locked up. not sure exactly what happened and not saying it was BYEs fault. its just an observation of what ive seen/heard.

    wondering what peoples prefernces were in regards to intake manifolds. i will eventually be running vn grp a mani(when i can find one) but was thinking a low rise single plain with fabricated elbow and 80-90mm throttlebody would do the trick. i dont really want to cut the bonnet for a high rise single plain setup i can help it.

    Same old story An engine goes pop And it could be for any reason But people get the blame When it could be A number of Things and faults, I'm hearing ya And what your saying Anyway all good.
    Yep And I love it when I see a Holden v8 show up an Ls it happens more than some guys are aware .
    For under bonnet come single manifold would do the job I'd say.

    yeah was thinking come single. i should really look into it a bit more in regards to physical height of some high rise stuff, if i can fit a high rise single or dual plain under there i'll go that way instead unless i find a vn mani before then. its hard to justify $6500+ for the twin throttle mani but will be happening sooner or later (more than likely later!)

    have been thinking of using mick at ovaboost for tuning but will speak to TK when the time comes, see who he recommends. will most likely also get him to do the heads and go from there with cam specs ect.

    From what zok has said in a few posts the come 4bbl is good I will be using one and is still taller then a redline.

    Mine is hq headed blow through carb currently but swapping in with new motor will be efi and thinking a nice elbow to a normal type throttle body even contemplating going electric throttle body so more easily set traction control up.

    I do not want bulge or scoop so will try as much as possible to keep all under standard bonnet height.

    With the carb it is nearly 100mm from base to air inlet I am running a procharger hat and still clears by a matter of a few mm.

    I think the come manifold is around 50mm higher then the redline so a tight radius elbow should be ok

    Ie something like these http://store.edelbrock.com/edelbrock...bows-90mm.aspx

    thanks for the link, those elbows look the biz. i also like the wilson ones as well, although they look quite tall in comparison. I will probably just fabricate an elbow out ali sheet metal as it will cost me bugger all and i can make it whatever height i like. The electric throttlebody setup would be very interesting to see in action.

    Why not a come twin throttle since its efi and boosted?
