R32 Gtr Getting Ready For Wtac @ Tunehouse

[Marko R1]

Money money money

As i said before...I envy your lifestyle John

[JohnGTR]

Yeah ... money, money, money ...all going into that big black hole!!

But I'm not giving up, it will be sorted out... I'm in my mid 40s and if I do not get this project finished and the car running to its potential then I might just throw in the towel.

Latest update...

- The Holinger will not be delivered until mid - late July. Has anyone got a spare gearbox to loan me for a couple track days? I promise (fingers crossed) I won't break it.

- Electric Power Steering pump installed and will get wired up into the Motec PDM.

- I'm replacing the Odyssey with a Lithium battery (its due to die soon)

- I'm looking at installing the adjustable Ikeya lower control arms

It's been close to 18 months and I still have not had a decent drive in the car yet...

I'm not sure if I am going to put in an entry form for Superlap this year ...

Yep, know exactly how you're feeling!

Welcome to the world of GTR owners......

[zillagtr]

Just finished an electric power steering set up on my GTR. Bit of stuffing around but works a charm now. Used a TRW out of a late model Astra. Pm me if you want any details.

[bigmikespec]

How are you guys wiring up these Astra power steering pumps?

[zillagtr]

Send me a Pm if your interested. It took a bit to get right and Im a sparky. Couldnt find much info off the net. But i think ive got it right now. Taken the car out now a few weekends now and no probs. Good mod in my opinion.

[JohnGTR]

Update:

- Astra Power steering pump installed by UAS using standard astra fuse/relay but is not setup with PDM yet. Will be hooked up properly in the next week or two by my motec guy.

- Holinger sent an email... box should be ready late June/early July... fingers crossed it turns up sooner rather than later.

- Rear lower control arms fitted by UAS, waiting for front Ikeya arms to arrive.

- Application to WTAC PRO-AM class was successful.

Now I need to get serious with getting myself ready for the challenge... need to lose another 10 kgs, sort out the right knee and get in some sort of shape (other than round).

It's gonna be fun!

[9krpm]

That's great news John.

Another BNR32 in that class to challenge the sea of evo :-)

[JohnGTR]

Received confirmation that the holinger should be delivered this week... hopefully it will be installed and be drivable again next week.

Now I need to get the wheel alignment sorted to a starting point, finish off some wiring and then get the car down to Tunehouse to check the tune and give it a tweak then off to get a feel for it around Sydney Motorsport Park...

Should be interesting!!

[Chris @ Tunehouse]

Thought you guys might be interested in the latest on the Tunehouse R32 GTR. We recently have been doing final mechanical work, check ups and dyno tuning.

We held a photo shoot last week, the photos have been posted up on WorldTimeAttack.com with specs of the car:

The machine hit the hub dyno on Saturday to be tuned by Tunehouse owner Jim. Comfortably and efficiently we made 500 AWKW @ 16 PSI, looking to go up to 25 PSI in the future.

With the tune done, the keys (so to speak) were handed over to John Boston last Sunday for a shakedown and test lap. You can check out his in cabin camera footage here:

And another of it moving out of the pits:

There are some minor enhancements to with fuel and oil pressure, but working out the kinks is to be expected of course.

The car is being entered into the open class @ WTAC this year and we are keen to see what it can do.

We'll keep you guys posted!

Saw this on Facebook, certainly looks the goods

[ssxRicho]

It sure is making good power. Looks like Boz is going to be a busy boy on race day as well.

[Dale FZ1]

It's certainly making the numbers, hopefully you can get it set up to put power to the ground.

Let's have a closer look at the aero please.

More detail around the splitter/undertray, and the rear wing + diffuser section would be great.

[evil_weevil]

beautiful!

i'll have to check FB at lunch to see the vid!

[stevena]

Looks great. Footage link doesn't work.

[Chris @ Tunehouse]

Sorry about the footage guys, the videos are hosted on somebody's personal account.

The aero and diffuser work is all custom, unfortunately there's not much more I can tell you than that.

Facebook videos are not working

What's with the torque, is the boost all over the place? Shocking in the mid range torque but 640Nm at 7500rpm

[Chris @ Tunehouse]

Boost level is consistent, our hub dyno picks up every little twitch in the output.

Boost level is consistent, our hub dyno picks up every little twitch in the output.

I know how a hub dyno works, you should be making peak torque at around 5000-5500rpm not 7500rpm. Something is causing you to lose a lot of mid range power?

PS. How do the RB20 Nics covers go with blow bye?

Any chance you might post up some pictures? That was the detail I was referring to, wanted a look if possible.
