At the wheels.

For reference on a very safe tune with an HKS2530, fuel pump, injectors, AFM etc on a relatively good condition RB20 at 14psi bleeding down to 12 I got 175kw-180kw on a 33c degree day. Pulled 195kw at 16psi with massive misfires due to coils.

Could be a freak engine but its hard to imagine getting that much power out of a standard turbo.

Mate - those figures are wrong.

Have a look @ the IT temp is -71 (IT stands for Intake Temp Sensor)

They have a broken temp sensor, how can you be in -71 degree's on a 24 degree day?

Your coolant would be frozen solid - like i said mate, they have botched your runs, there is no possible way to make 170rwkw from a factory RB20 Turbo on 12psi

I suggest you find another tuner, if they can't even maintain or setup their equipment correctly, goodness knows what the tuning is like.

it was on a 41 degree day?air temp inside the shop and dyno room with the fan going would of been lower...

im not sayn u are wrong but i have a friend with the almost the same mods and he gets his car tuned at a different place and it makes 166rwkw with stock turbo???? my boost controller is set to 14.4psi on hi boost but has bad boost drop to 12 thats y i said on 12psi??? i have been told they were a good tuner

If it was 41 degree's outside then that is even worse champ.

The dyno sheet AT:24 (Ambient Temp) says 24 degree's was the temp during your tune/runs etc etc.

Which is virtually 20 degree's off, not a good thing at all, quite signifigant in terms of accuracy. ;)

I say this because if they can't get simple weather corrections/sensors working, i would be dubious of other things like AFR's being correct (ie the sensor being poorly calibrated/broken like the other ones clearly are)

That then has follow on impacts to the tune and at worst - your motor.

they didnt put a thermometer on it so the intake temp wouldn be right.. i dunno then coz my mate also has one with 166rwkw and has drove mine and says goes better than his... pretty sure if u look at the otha 32s on here u will c some with more power with the stock turbo..

Mate you need to calibrate the dyno if you are ever going to hope to have meaningful results for everything from the power to the AFR's

Plenty of stock turbo results to be seen here:

http://www.skylinesaustralia.com/forums/Rb....html&st=20

Norm is 145-160 give/take for 12-14psi.

130-140rwkw for 10-11psi

Normal temps (22-26) - Let alone on a 40 degree day.

It seems you don't really understand fully how a dyno works...

I've told you that the dyno they are using is not correctly setup at all, and this could easily result in a a poor tune and/or your motor death or serious damage over time.

So wether you choose to take what i've said seriously, or just don't care about your car/motor, is totally upto you.

I've seen plenty of people dudded by poor work over the years and it has cost them plenty of money to get it fixed down the track.

as i said it must be possible as i looked in the link and only looked at a few and spotted one 170rwkw on 1 bar boost stock turbo???

1990 R32 75000Kms

RB20DET Stock Internals

Stock Turbo

FMIC

POD

3" TRust exhaust

EBC

BP Ultimate

170.2rwkw @ 1 Bar Boost

Agree with Ash. Wouldn't be pulling myself over those results. Obviously a dodgy maintained, high reading dyno to keep customers like you happy who don't understand the basics behind how dyno's work and calculate the data.

People comparing chassis dyno results are only kidding themselves. To many variables.

lol -71 degrees Intake temp. your fuel would be freezing in the inlet...

you need to understand the dyno software takes into account ambient temp (AT) and intake temp (IT) and corrects the power figure accordingly. withh figures like those who knows what kind of power figure correction it would be applying. but I can tell you now it's very, very unlikely that your 32 GTST is making 170rwkw @ 12.5psi. just as unlikely as it has -71C intake temp...

upsetting to see this mate, ive always heard good things about powertune

maybe you should take on the info richard and ash are saying and give them a call and ask some questions, and try to get some answers and hopefully a re-tune/refund/etc..

also, keep your eye out for an rb25 turbo, a nice bang for buck upgrade for the rb20 :P

yeh i have rb25 turbo and gtr injectors on there way... maybe they f*kd up.. ive seen a few otha ones making like 180kw + with stock turbo so i dunno... yeh powertune is supossed to be great

i think they f**ked up man, ash knows his shit

call them

yeah I dunno about this bloke but I have seen an RB20 silvertop on an A31 unopened with an Impul ECU, East Bear front mount GT-R cooler kit, 3" zorst no cat or mufflers and a R34 turbo pull 170 rwkw, the car's track performance was able to speak for itself (ie was able to cane a stock R34 GT-T, and give my old 160rwkw VN SS a hiding lol; I admit there would be a weight advantage since this A31 weighs 1200kg lol)

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
