Ben's R32 Gtst Build

[sav man]

Top job at the railway crossing/dip think you were one out of only three cars that kept it pinned through there and the only car that produced sparks

pics of said sparks? Gotta thank the Penske's for that, they handle big bumps like that with no problems

[trez]

Just checked the pics I have and I missed the shot right over the railway tracks sorry ....Have a pic just before and just after the crossing...dam

I'll check what shots my mate got.

Now the car has been in a big event, I thought I better post some findings about the car.

1) You need a decent sump! From the datalogs, the oil pressure will constantly drop into the 0-5psi range under heavy braking (cornering and acceleration forces don't bother it). It only does it for less than a second at a time, but as we found out, you're driving a time bomb.

2) Spending money on good shocks was worth every cent. We probably only tuned the car 70%-80% of what it could be, but the way the shocks handeled the big bumps really surprised me. Coming from the Bilsteins in the GT-R (which I was happy with), it was in another leage.

3) airbox and radiator worked like a dream. Intake temps were only 10-15deg above ambient. And the coolent never got above 85deg on a stage, you could see the thermostat opening and closing from the datalogs. As the temp woudl go from 85 down to 78, then back up to 85 2-3 times over a 30km stage.

4) Fancy dash was worth the money. The data from the logs was invaluable during the event, and I found the dash clear and easy to read during the stages. If you're racing you will spend just as much money on gauges as a dash.

5) ITB have plusses and minuses. They have given the same effect as bigger cams, with a loss of power down low, but it does keep the power going right to 8000rpm (and beyond if you had the turbo for it). I personly hate the throttle responce from the std 20, I think it makes gear changes slower (waiting for the engine to rev down so the box will engage the next gear), and it makes the engine feel like it's attached directly to your foot. I'm going to try some cam gears, and hopfully that will give me some responce back..... but if I didn't need to drop the rev's back to 7000rpm from 8000rpm, I don't think it would have been as much of an issue. I don't think I'd recomend it for other people, but I personly think they improved the entire package.

6) catch can design needs more thought than just hooking a single tank up. Constant high rpm needs oil restrictors, oil air separator, thicker oil, and a return to the sump.

Great to hear it went well bar the Oil surge, Time to pull the donk and freshen it up I think

0 hour motor should help with response too

[Marlin]

I'm suprised re the oil surge Benny. Mine did about 10,000klm of competetive driving before a big end went, but I'm blaming that on running 30 odd 100% pace laps in a Qld summer without an oil cooler! lol

Do.did you run a litre overfull?

[sav man]

I run it to the top of the hump of the dip stick, I think it's about a litre if not more. It seems all 20's will eventually run a bearing, just not as soon as mine.

We pulled the engine down last night, and bearing 3 was the one that died.

[Marlin]

uhuh...... Mine was #6

I fill it to the full line, then add a litre.

[sav man]

I thought it was odd it was #3, as all the other ones that have died have done #6 from oil starvation.

[Dave.TAS]

I've had 3 rbs spin on number six yep.

[zebra]

Ive done #2 and #3 and 4

Its like the Lotto lol

[SimonR32]

I've done #1 in my old GTR

[paulR32gtr]

How you finding the ABS setup Ben? It's a commodore unit yeah?

[sav man]

Yeah ABS works well, it's 4 channel unit out of a VY Commodore with traction control (tc isn't hooked up though). Idely it'd be nicer if it was slightly less sensitive, but you only really notice that on a circuit.

[eightsixboy]

Congrats on the car, looks awesome .

I'm sure you'll gain some more low end response with cam gears, i'm going to do it on my 20 soon.

[DJRIFT]

thought id post up some pics we got before and during targa

the day ben killed the engine.

This nissan flag poped up at least once every day during the event and was usualy acompanied with a toot of the horn and a bit of drift.

Stopped in queenstown. just one of the many stops through out targa

checking results. Gotta keep on your game

Belt up bitches

And almost to the finish line. Pre finish team meet.

5 and a bit days of racing the car pulled up pretty good.

Im pretty confident you will see this team about again.

[sav man]

Did the service crew take the pic of the Nissan flag?

didn't upload the pics of the car when it was waiting on Bradshaw bridge to tackle Arrowsmith.

I've got a new high responce bottom end ready to go. Just need to bash some restrictors into it, and sort a sump out. ASR looks the go for the sump.

[zebra]

Whats the details on the new short donk?

I like the paint job on the car too

[DJRIFT]

top secret untill tested.

the pics from arrowsmith are on my memory car for my broken phone. will have to wait for them.

[sav man]

yep it's top secret

[TJHill]

So this parked outside boost automotive. Looks real nice mate
