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.
