Given its a hub dyno what sort of "correction factor" do we need to take into account to make a comparison to say a dyno dynamics dyno.

Typically I've seen hub dyno's read around 10% higher - would I be on the right track?

not really, quite a few cars from dyno dynamics shops read way over mine or the more reliable shops will run within 3-6kw, the dynamic test systems dynos like rank rotary and russell performance both read 10-15kw over mine.

Very nice, looks like fun - how much boost is it running to do that?

Something I'm not too sure about however is that last comment - especially performing anywhere near as good? Can you elaborate please, I certainly can't see anything on that dyno plot which shows it having anything over a GT3582R - what I see on that plot is a car making GT3076R power with GT3582R lag. At this stage I have not met anyone who have had reliability issues with a GT3582R yet and have various mates using them for circuit racing at quite high boost levels, making much more power than what you have posted in this thread... and if you have had a Garrett BB failure because of contamination it wouldn't be the turbo I'd be criticising.

At this stage it looks like you can buy a 6boost manifold and a GT3582R for the same price as just a K5-660R by itself, so I am at a loss for what the advantage is? Please bare with me, you must expect being questioned if you are going to make such statements - the Blitz/KKK turbos are definitely a minority amongst the tuner turbos so if someone comes up with one on their car, and makes wild claims about performance it definitely makes one want to know more about it ;)

Cheers.

i should probably add i sell/ fit and tune 10 garret GT3540 to every other turbo due to sheep mentality or pure bugetary restraints, i like the gear and it offers the BEST VALUE but definately NOT the BEST PERFORMANCE. i must admit my favourite baby SR turbo atm is the GT28RS 200-240rwkw over anything else on the market be it blitz, trust hks etc... so i am not anti garret ;)

Oh OK - were the dd's in shootout mode?

Yes, the Forced Performance turbo equivalent of the Garret GT35 also shows up the Garrett as being inferior based on these back to back tests:

Absolutely, I can see that - ditto with being not a Garrett fanboy... but I like to have the advantages pointed out to me why turbo xxx is better than turbo yyy when it has been stated that way but there is no obvious proof. For what its worth, your dyno plot for 340kw @ wheels looked HEAPS like a mate of mines running a .82a/r GT3582R on his RB26DETT with very similar mods. He ran 371wkw on a Dynapack hub dyno running 20psi in a GTR with pretty similar spool. Definitely sounds like the Blitz beasty is a decent unit.

And on average from results I've seen (and I always run on Dynapacks so making my kw smaller isn't really in my ego's interest) Dynapacks read about 10% lower than Dyno Dynamics, though it seems there are the odd DD dynos that read quite high - there are always exceptions to the rules depending on who has set it up etc.

yeah, seriously now i run any serious customers car up before i work on it to get a base line.

Trent do you actually do any tuning or spanner work? looks to me that you spend too much time on the internet

i only bash keys whilst on the phone or orgainsing parts etc.... stupid customs... got a container of front cuts and engines coming and there is way to much office time involved.

Hope you dont mind Archie.... :P I had a HKS Low Mount T04R manifold etc ready to try a T04Z, but Archie's car changed my ming about running one on a 2.6L. Dont know the exact spec of the engine but it had std cams and displacement, though it was running forged internals. Turbo was... http://www.skylinesaustralia.com/forums/Rb...tml&hl=T04Z

By no means was it a dud, but it definitely is a BIG single when it comes to how it drives

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
