GTS-t VSPEC or Steve-SST,

which GT30 core do u have now, can u provide the CHRA number?

it might be worth your while to go up to an A/R .82 exhaust housing.

I'll get the number off the turbo tonight and post it up for you.

FATGTS-R, Are you sure it wasn't 650rwhp, cause over here all readings are done in hp. Either way, if you do try and trick the temperature readings on a DD Shootout dyno then the temperatures are shown on the bottom of the page, so it would be obvious to everyone that cheating had taken place. But I do agree that dyno's are just a tuning tool

Geniune accredited shootout dynoshave many of the settings you talk of pre set and the temps etc are printed on your print out.

FATGTS-R what is the shops name so we can see if they are one of the accredited shops with the correct software or just the standard issue.

I have now been convinced as to what people have been saying for a long time, Dyno graphs dont mean jack shit.

My car is currently in a Bayswater workshop in VIC getting some mods done.

The workshop in question has a brand spankers DD 4wd dyno.

This workshop together with APS built and developed a twin turbo kit for the LS1 engine.

On there own dyno the car made 460rwkw. On the APS dyno it made 510rwkw both times on RACE FUEL.

The car recently went interstate for a Holden vs Ford gig and won the dyno comp with a ridiculous 650rwkw on PUMP FUEL. Go figure.  

The owner of the workshop showed just how easy it is to make a dyno read a lot lot higher than it should.

One example was to "manipulate" the dynos temp sensor for a higher reading in shootout mode.

The next example, and one I did not know about was that supposedly each car that goes onto the dyno is meant to be calibrated so that when the car is doing 100km/h so is the dyno.

He ran the same car twice in a row, one time with the dyno geared correctly and once with the geariing tweaked a tad.

The difference was amazing, the outright power wasnt that much higher, but higher nonetheless but the average power was about 20kw greater all the way across. Overlapping the two graphs you would think they were two different cars.

So to all the people who write "dynos are just a tuning tool and power graphs should be taken with a grain of salt" I 100% agree with you.

This post has been passed on to Dyno dynamics to be sorted buy they say its just some fairy tail some one told some one ,as ppl do.

Actually the car made 688 rwHP at the H v F show, which is almost identical to the 510rwkw on the APS dyno.

Also, Peter from APS himself admitted (on ls1.com.au) that it was NOT on pump fuel, but his "secret APS brew".

EDIT: also, it wasn't in the dyno comp, but only as an exhibition car.

It is very rare those high hp cars run normal 98 rom fuel. Its mostly 100% C16 or 50/50 C16/98

All our dyno comps are done in rwhp over here, and as you can see our readings match up to what they did on the APS dyno, so maybe you should all stop your knocking and try a bit harder:D

I am at 438hp@wheels at 1.4bar on stock internals so i aint that far behind :rant:

  GTS-t VSPEC said:
Well if you believe your figure then why do you have such difficulty believing ours?

We use Dyno Dynamics dyno's in Shootout Mode, which is the acknowledge standard Australia wide.

Because thats the highest figure i ever got, and realistically its only around 400hp@wheels or even a bit less

Blah dyno reading doesent mean squat unless you can use the power and get it to the ground, and if ya getting wheels spin in third gear then..............

Put all this to rest and run down the damn 1/4 will ya :rant:

Mine will be going on the track soon at Phillip Island and Sandown with the rest of team WANG Victoria to see what it can do in the real world!!

I know you allready know this, but Phillip Island and Sandown aint 1/4 tracks, so where is the true comparison???

    • For DBA, check out their guide table here. https://dba.com.au/wp-content/uploads/2023/01/Direct_Replacement-Guide-2021.2.pdf   Additionally they have some other guides and info on how to make sure you choose the right pad.
    • Sorry, just assumed that talk of coloured pads meant EBC red/green/yellow/shit stuff. I don't know the DBA pads, but it's a reasonable bet that they will be OK. DBA make good stuff generally. Those 4000 series rotors I linked to are very good. I may well replace the RDA rotors I have with those when required.
    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
