    The regulator will act more like a check valve than the dampner will.

    yeah that starting problem is usually when the stock reg is binned

    Dampners not a valve and pressure is always in the feed line. :)

    I couldn't wait so got a temporary battery & slapped it in for a test drive :D

    Goes very well, spools up earlier, runs a lot cooler, sounds nicer :D

    Next up is a dyno session & tune etc.

    Have got about 50kms on the clock so far, have had to pull the idle back down again as the engine frees up a little.
    Was tempted to go slap it on the dyno today & see how everything looks but had work to do (earning money rather than spending it).

    I did take it down to the testing station for it's WOF (safety check thingy) & couldn't resist trying about qtr throttle up to ~6500RPM in 2nd
    It spun the big 275s like they were butter :eek: still on only ~9PSI :eek:

    Ahhh yes I think this could be fun :D :rofl:

    tassuperkart Its a lie I tell you!

    Best thing you can do with that motor M8! Dont be afraid of it just coz its relatively new.
    Post whore here, sry in advance and I have my firesuit ready as quite a few "purists" still live in the stone age as far as engine running in is concerned but:

    Pussyfooting around "running in" engines is as largely useless as the nefarious practise of "warming up" with extended slow cold idling........ Slow idle warmup should be considered engine ABUSE!
    The ONLY engine that ever benefited from warmup is old rotors.... BEFORE they had decent seal kits.

    The only "running in" of any engine I have ever built, road, track and my superkart race stinker engines is the first 10 minutes or so where revs arer held around 1800rpm to ensure good cam face and cam follower break in and to ensure water systems are purged and look for oil and water leaks.

    Give it a good flick right up the revs and plenty of throttle whenever you can! Give it somethinbg to do!!
    I always advise against low down lugging (at any time really) and sustained high rpm for a couple of hundred initial K's.
    After that, drive it like you hate it and enjoy your toy. Your wearing it out anyway! *firesuit ready*!!!

    Sensational job M8. Enjoy!

    I agree, I tend to take it easy for the first 100kms or so in case of a stuff up that is just waiting to show symptoms. Say an oil gallery is blocked or whatever & a bearing is about to crap out & spin - I would rather have the chance to hear it going at lower power settings & shut it down. On a dyno at full noise ... well it would just grenade :rofl::(

    I pretty full on with work for the next little while but will try & squeeze in some dyno time early next mth.

    Like your attention to detail kiwidude, some people just stand back and throw money at a engine, you actually think about what needs to be done to to get the required result :zlove:

    Engine has had about as much of a run in as I can be bothered with :)

    Zemulator acquired, will be on the dyno tomorrow if all goes according to plan :D

    Anyone got a rom file for a base tune similar to what I will need?

    pump that boost :)

    only way to find out if it holds together.

    355kw at the axles @ approx 5500RPM on 22 PSI boost
    2490NM @ approx 5500RPM

    That's enough for some good fun at the track me thinks :)

    Will detune it to ~18PSI & leave it at that, should still be about 320Kw in any case.

    YAY! :br:

    I'd call that "healthy" - a bit like the lungs on Cameron Diaz .... or have I just dated myself

    tassuperkart Its a lie I tell you!

    Its more like the "lungs" on Pammie Anderson M8...........!!!! LOL.

    355 @ 5500..... jeezuss.. thats a stump pulling torque-monster!

    Nice and impressive figgers M8.

    Thats a great power figure esspecially the torque. How come you stopped at 5500rpm is it because the motor is still new and not fully run in?

    That was the peak power, still had ~ 340Kw @ 7000RPM torque had dropped to "only" 1850Nm.

    The package wasn't really designed to make any more power than that & it seemed as though the turbos were maxing out - based on the boost tapering down.
    I'm not convinced the turbos had run out of puff though & think it was more likely the actuators or the controller causing that.

    Need better down pipes, EBC & cams for quicker spool but it should be fun enough for now :)

    OK so I took it for a drive :D
    It was no good - flat spot at part throttle in mid revs :confused:
    Hooked up the laptop & found the problem, a row wasn't set right in the map :rolleyes:
    Got in there and fixed it, loaded it all & took it for a burn :D

    GOOD!! IS FAST!! :D:D:D:br::br:

    thats awsome man, must freak u out when boost is hit :eek: love it :zlove::zlove:

    Have ordered an electronic boost controller to help control the boost a little better & will at some stage be getting a better tune sorted. I'm not happy with the bottom end pull at the moment, it should be pulling a little harder below ~4000RPM mind you it is still a fresh engine so it may free up some more.

    Oh & I have entered in Super lap at Hampton Downs :)

    MORE POWER!!!! and earlier turbo spool :)

    Next up I'm going to alter my down pipes to the later design type & see if I can pick up some even earlier boost. 24PSI @ 4750RPM te he he.....

    Please remember this is still running standard cam shafts & the porting work on the heads is not extreme, valves are all stock, 2.5" twin exh & she sounds fricken awesome :D:D
