    no.

    boost drops off for 2 reasons
    1 .actuators cant hold
    2. at higher rpm the engine ingests more cfm psi drops off (psi is restriction to flow)

    gt28rs dropped off more because it ran out of air and engine could flow more .

    this setup will do 600rwkw with bigger turbos.

    although cams would be the next upgrade 264/10.5 lift


    I saw the post to the snowy too late :(

    Do it next year, I'll send you personal reminders if you want so you know the second it's open ;) lol.
    I'd love to get a comparison between us just to see how far behind I am! ;) lol
    You have a 300kmph set up! Needs to be one zed there on the plaque and I can't see me making it this year lol.

    Not in comparison to yours really, but I'm rather curious to see what mine does now.
    I've been told you aware what I'm playing with :) just perhaps not the other late adjustments :)

    Have to actually catch up in person not just with each others cars at the workshop

    Gotta love 700rwhp at 5000 rpm :confused:

    Well done.

    Thanks guys

    Estimated at engine by the dyno is 887.8 BHP

    I worked out around 900BHP with 16% drivetrain loss

    touching 1200nm of torque at 4500rpm while still holding 800nm at redline.

    The turbine side would be reaching its limits .

    the NS111 turbine wheel is rated up to 450hp each so there is your 900.
    although garrett wheels tend to make a little more than they are rated.


    the GTX2867r will go over 600rwkw if the turbine wheel can cope but I would go straight to the GT3071R from here

    1000hp VG isn't looking too mythical now is it ...:br:

    Wow, awesome result, congrats :br:
     
  11. Anti

    Anti 14.7 x 14.7 = 44.1

    How do you think the 3071s would drive? Or you'd want to step up to 272s to make them work?

    on dyno they will spool good,full boost by 4500

    on street a little less transient response

    272 wont necessarily make more power with the same lift as much as shift the powerband
    I would increase lift for more flow
    but if you want power later in the rpm then increase duration.

    Are you using crank trigger or oem cas? Your poor clutch
     
  15. BLACK BEAST

    BLACK BEAST SLICKTOP TT R-SPEC

    OEM but all electrical components like CAS ,TPS etc were bought brand new.
    Everything I have is stock or just bolt up upgrades ,apart from my 3 inch intakes.

    Just put a rebuilt kit into the z1 twin plate and it's holding it easy .

    Last one was worn and screeching on the dyno with Gt28rs at peak torque 4500rpm

    We both know our clutches arnt rated for that power ;)

    Let's see how long it holds up :)
     
  17. BLACK BEAST

    Hey Procky clutches are rated by torque

    It will hold up to 700ft/lbs (950nm) of torque

    I can't run full boost unless at the drags any way

    At the track low boost 18psi is already 445rwkw ,still too much power :p

    So it' will be fine .

    There is also an extreme pressure plate version that holds up to 820ft/lbs

    Building a simmiler engine build, few questions. Ams manifolds are way bigger then the head exhaust ports on the head, did you do any porting and polishing or just gasket match? Also running oversized valves with a bigger cam, is there a reason why you dident oversize thr valves or was flow already enough for your build?
