For people who are wanting 200rwkw out of their "stockish" RB25DET heres something to consider. The dyno graphs below represent my car on 2 different dynos.

The first one was done December 03 on a 20degC day and made 153rwkw. Mods were:

* bleed valve @ 13psi

* Chipped stock R33 ECU

* Turbo back zorst (with crppy compliance cat)

* K&N panel filter

The sencond one was done June 04 on a 10 deg day and made 195rwkw.

For a bit of fun, lets see if you can tell me where the extra 42rwkw came from :)

come on dude, tell us.

I am on my way, just waiting for the tune now. The Powerfc on factory maps = 200km out of a tank.

I have -

Split Dump all the wat to the Cat

Hi Flow Cat

3"5 Exhaust, 4 inch Cannon

Front Mount Intercooler (stock plenum and BOV)

Partitioned Pod Filter

HKS Exhaust cam Pulley (not fitted yet)

Apexi Power FC + Hand Controller

Bleed Valve set at 10psi

18" 235 Treads

10% Mix of Toluene

Stock Turbo

Currently on about 150rwkw

Aiming for 200 - 210rwkw after the Tune. Apparently its very possible.

ones a dyno dynamics.. the other is the dynologics.. and lets guess that the dynodynamics might be in shootout mode correct? and maybe has some temp correction thrown in for good measure..

do i get some candy?

good pratical illustration though rigga :thumbsup:

That’s why people who trying and argue, that their car is faster because it puts out more power on a dyno. Is a load of bull. I have seen similar cases of a car on one dyno putting out 320hp and on a different dyno putting out 360hp. With nothing changed to the car.

If people say that their car is quicker because it puts out more power then mine I laugh. The argument stop on the ROAD!! You could have a car that does 700hp between 7 – 8k rpm and a 300hp car with a power range of 4 – 7k rpm I reckon the 300hp car would beat it over a ¼ mile. But the guy with the 700hp car can still claim that he’s is quicker because his car puts out 400hp more……. ???? Am I right in saying that ?

In other wirds RiggaP has shown a good example of that, Cheers Mate.

Gordy, Quite easy really:D Shootout mode dyno provide a list of details at the bottom of the screen, which records intake temps, ambient temps etc. Shootout mode 2003 has green writing down the bottom, but this is no longer current. Shootout mode 2004 has blue writing and has an '04 logo. These dyno can no longer be manipulated to provide higher readings.

Shootout mode dyno provide a list of details at the bottom of the screen, which records intake temps, ambient temps, yada, yada, yada

yup, I sort of know that :thumbsup: - but I was thinking maybe rigga had photoshopped these details out to make it another interesting point of discussion.. which it is already :)

I have noticed this over time the extra details on each printout. As part of their dyno "subscription" (purchase/rental/lease?) are the dyno operators required to get the new software with each update.. or is it optional?

Take it to a Shootout dyno to get consistant results.

Common, you know that's not true, I can get perfectly consistent results running a DD not in Shootout Mode. After all, I can set the parameters exactly the same as Shootout mode, the only difference is that they are locked and displayed. That does not mean that they are not set correctly. I believe that the Shootineers Code of Conduct is far more important to consistency than a piece of software.

Sorry, that might sound a bit harsh, but I am getting a bit tired of DD shoving Shootot mode down everybody's neck as if it's the be all and end all of dyno's. :thumbsup:

The cat.

Correct. This was the only mod done between dyno runs.

ones a dyno dynamics.. the other is the dynologics..

Also correct, and forms the very reason.

So heres my point; Dynos are a tuning tool. Anyone chasing a dyno figure is missing the point IMO. As my example has pointed out, you could achieve 150rwkw at one place then have another place "retune" the car and achieve 195 without effectively doing anything. I'm not sure anyone with half a twit is going to argue you can get 42rwkw by adding a high flow cat.

A dyno figure is not going to give you any idea how fast the car is going to be, and because of this, dont mean squat.

    • Its also worth mentioning that 30 years after it left the factory and god knows how many missed oil changes since, there is every possibility that one or more lifters are ticking because they are sticky/gummed up. To resolve that you need to pull the cams then pull each lifter, disassemble, clean, reassemble, soak in oil and re-install, and they should come up good as new.
    • What air filter are you running? Is it a panel filter in the stock air box, or a pod filter? Is the air filter the type that is oiled?   If you unplug the IACV, what rpm does the engine idle at?
    • Reading through the engine service manual their advice is do a cylinder balance test. Unplug one injector at a time and see if the idle drops a consistent RPM. You can also do this using a Consult cable which is easier. They also call for unplugging the power transistor, then with the engine off and the fuel rail unhooked from the manifold verifying that you have good fuel flow (even injection, no dripping/leaks, etc) when you twist the CAS by hand. Also verify the spark by pulling the spark plugs and allowing the plugs to ground and turning the CAS by hand. I would also start doing the sensor checks and idle valve checks in service manual. Make sure the MAF tests reasonably, the intake air regulator is sane, etc. You may have to get new spark plugs.
    • This sounds very old of me, however since buying the Tiguan shit box, my view on shit boxes have changed.
    • I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way
