Even @ 330rwkw on E85/.63 - that is pushing then limits of believable. But at least its almost believable rather than outright fudge.

Maybe low 20's its believable (330rwkw that is). A 3582 .82 wouldn't make that much "claimed power" at those boost levels on E85.

you know trent from status uses the same dyno... with the same calibrations, and has had similar results on customers cars with a similar turbo set up?

everyones quick to jump on the dyno debate. If we had a drag strip in SA i would seriously consider it... with previous tune of 360 rwkw's i managed a 1:18 flay around mallala in a drift car on street tyres. this was beating 330 rwkw gtr's that were done on a mainline dyno (willall) so clearly some of you need to pull your heads out of your arseholes and face reality that such results possible.

ever think that maybe mainlines read low? I had an RB20 r32 ages ago with a 25 turbo on it with an EEPROM chip remapped. made 148 rwkw on a mainline.. where as on a roller dyno (DD) it made 180 rwkw.. and on the AMM hub dyno made 185 rwkw with the same correction metiod.

19psi though mate...

5557 .63 made that same power (roughly) on >30psi of boost. Albeit on a 2L SR engine, it's still something. Why do SO MANY people make around the 300rwkw mark on 1psi less? Surely there isn't 90kw difference in reading between the dynos....

Just know that it's all about how much you enjoy the car, and how well it performs - a dyno is simply a number, and doesn't mean ANYTHING in some cases. This is one of those cases...

the whole point is that a 3076 cant push enough air to make 400rwkw.

and its very misleading to forum users that think they can go out and get a 3076 and make 400rwkw its just not goint to happen. its a 300rwkw turbo with E85 you can get 340-350rwkw out of them thats about it.

yes your correct becuase thats exactly what it did.....

the car in question was initially tuned on this dyno by amm using those exact corrections so i gave simon that graph today purely as a direct comparison to how it was before. the result be a 40odd kw increase over the previous setup. i had no real choice there.

i did todays whole retune using more "roller correct" corrections and in actual fact it produced 357kw. i dont think that turbo is gonna do too much more and i had no interest in trying. the result was great as it was.

at the end of the day, its a tuning aid and a VERY good one! the 397 was merely a reperesentation of todays gain.

I don't know what dyno it was on, but I remember recently someone pushing around the 400rwkw mark from a 3076 of some kind, but on a ridiculous boost level around 30psi - WELL out of efficiency

i bet they'd find that if they dropped the boost and tuned it accordingly, the loss would not be dramatic.:thumbsup:

I must have the wrong thread here I thought it was the 400rwkw thread, not the 390rwkw thread. Can anyone link me please? :whistling:

Lol, so true.

Im pretty sure the dyno blew up when he recorded a power level of over 9000

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
