Interesting Build - Quest For Mid 9 Second Streeter

[domino_z]

Martin hows the tuning going on this? Are you maf or sd tuning?

Looking forward to results, and also that dyno overlay if you can

[Martin Donnon]

Sorry Domino, been a bit caught up with Targa Adelaide and all the associated work

This one is on the front-burner from here on in until completion. One of the 'tricks' we worked out is that to install the Greddy turbo kit you must have a Greddy top pipe kit as well! Thats done now.....

SD tuning only in something of this 'size'

[Martin Donnon]

Ok engine back in car.......fire it up this week

[Martin Donnon]

Proof as to engine back in

[Martin Donnon]

Its alive, and sounds the goods

[Wardski]

Nice

[Marko R1]

What material is the flywheel made of? These r35s sound very metallic on crank and to me they almost sound like the flywheel is made of titanium.

This car sounds incredible

[domino_z]

alot of flywheel rattle in these cars

even more pronounced as you add mods and put more wear and tear on the drivetrain

[Martin Donnon]

This package has probably the best flywheel setup their is....we totally re-engineered the whole thing so that never, ever in its life can this GTR ever make another flywheel rattle noise. From that point of view it behaves like a normal car.

The noise you hear is the engine/turbos as it doesnt have an exhaust on in the video, its straight out the dump pipes

Just wouldn't be a GT-R without the rattles

[Marko R1]

this is interesting - how does the flywheel become 'loose' & why?

assuming the flywheel bolts run straight into the rear of the crank like a conventional engine - are the actual bolts under engineered or not correctly torqued from factory?

[g35me]

Martin, is this running a Greddy intercooler? Is there any advantage in the Greddy intake manifold?

[Martin Donnon]

Running in dyno pull at 20psi of boost pressure. Responding nicely

[g35me]

So what are the numbers? After the weekends results this is where I want to head.

[domino_z]

this weekend's results proved it isn't how big the numbers on the dyno are, it's how much of that power you can actually put to the ground

Your not wrong there. I was actually a little surprised at the 1 - 2 results.

[domino_z]

i'd stop at full bolts on and mod'd stock turbos, and spend the rest on a set of A005's for the stock 20's for such events

pretty sure Martin and Seb have run A005s iirc - Martin could you get away with A005s on rear wheels only and stock bridgestones up front?

Arent they slicks? If they are they are not allowed. There must be a perfect combination of power vs traction for this type of event. Road surface will obviously be a variable factor. It would seem that Martins WR600 was better suited than Seb's setup.

Temora was all about traction over time.

Sebs Alpha 12 was easily faster than the WR600 through the acceleration increments once it had achieved full traction, however finding that traction balance was difficult on the day. It didnt help that Sebs car was running Dunlop road tyres where the WR600 was using the SportMaxx version (as a test, which worked well)

Towards the end of the day when Seb really got into the car it was indeed faster in elapsed time than the WR600 head to head however the track had gone off to the point where no more fast times were run. On a dragstrip it would have been a very different story - as you might expect.

Temora is no real test of car performance rather the ability to adapt to the surface.
