The piston's will be fine !

It's a well tuned engine. We could tune it up to over 530-550rwhp if desired - no problem... but then we really would cook the internals. We are going to run the engine in this state of tune for a while before doing the internals. At this stage though, 300 reliable day after day rear wheel kilowatts... and a lot of cash later =0)

good stuff.

there was a dyno day here in melb last week for the commodore club. A vh 253 pulled a whopping 24 kw at the treads. Was pinging so bad. everyone laughed at the poor bloke.

with your gt30 turbo you running an external gate, and what sort of time does it come on boost by, would be lots of fun when it does.

Yeah we have an external wastegate. When the Boost comes on around 3500rpm it pulls damn hard !... hence the requirement for traction control =0)

I will be doing some more vids of the launch control, traction control and driving etc soon, i am still getting the dyno sheet scanned.

It could produce way more. The head just won't flow much more unfortunately, so with the internals done, cams etc, it should move up over 500rwhp. It is just tuned for reliability atm.

what happens.

do you get better launches or what.

is it autronic that has that device.

does the computer tell the motor to produce less power, so u dont brake traction, or does the arse end bog down, and just go for it.

i have heard people throw the word around but never asked how it works.

is it costly.

It is purely controlled via MoTeC. MoTeC misfires cylinders to retard power momentarily depending on the percentage of tyre slip v's throttle position. Basically, in the pouring rain, you can drop the clutch and all you hear is a popping sound and you scream off - way faster than you could possible imagine for the wet. It is great for hanging it around corners. Simply nail the accelerator and as soon as the prescribed slip is achieved, the traction control grabs the rear end and stops you flying off the road whilst still allowing control to maintain the corner.

Combined with launch control, traction control and flat throttle gear changes, it has provided a package that has made this car simply amazing to drive. Launches are sensational and slaps a smile on your face as wide as the car. Autronic has a traction control module, but no where near as good as MoTeC (just my opinion though).

Other sorts of traction control such as on the twin turbo 2JZ supra use a pre-throttle body restrictor to reduce air flow and accordingly power to the motor. This is poor by comparision as it prevents boost from being produced and offers poor performance. MoTeC maintains boost all through periods of traction loss.

The traction control module is around $800 on top of the price of MoTeC. All up, you can probably expect upwards of $6000 installed and tuned.

Ahhh, one of the most accurate dyno's in Australia... or in New Zealand.

It was on a new direct drive line Dyno owned by Speedworks in WA. Basically, you take off the rear wheels and bolt the two units up to the hubs. That way there is no slip. It is also brilliant for 4WD and AWD vehicles.

I do have some video footage of the setup, but haven't converted it to digital format yet... if you are interested.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.

      ECU sees many times the speed than speedo does (R34 swap)

      It's needed for rolling idle up, and I think it is a decider on VCT also.

      I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
