Ok - the SBS theory is officially busted.

5 GT-R's from Vic - where we don't suffer from SBS - just made the trip to NSW all on semi-comp tires and packing a decent punch to complete 2 full days at Eastern Creek and Wakefield and have seen no sign of SBS. All that was needed was an extra litre of oil - and making sure the oil to start with is good stuff.

So SBS - Busted.

R32 FFS however (firewall fire syndrome) is definitely confirmed. 2 out of 2 R32's igniting their firewalls at EC is definitely something I'd be looking into if I was an R32 owner. That shit isn't cool. Engines can be fixed. Burnt to the ground shells are a little harder. Luckily that stuff burns slower than a cigar but still...

WTF?

Anyway, If you didn't all drive like girls you would get oil surge

What did you guys think of Eastern Creek, and how did you go for times?

[T04GTR]

lol. i needed 2L extra. unless my oil pressure guage needle is efected by hard left handers

although its pretty hard to hold a nice line while staring at a guage to see it bounce. wich it does. (not the factory one)

ps..WTF does sbs stand for?

We have had Archie spin a bottom end, Robin spin a bottom end??? Didnt they? Could have been stired std motors with T78s that did that though, never really asked

sbs = sump baffle syndrome, it causes gtrs to sit in the garage instead of on the track until they have a baffled sump. It first appeared in NSW after a couple of cars spun bottom end bearings on the track (mine included), but has never seemed to spread to Vic.

Wierd.

As I said - decent oil and over fill in the answer.

It hasnt spread here because it simply isnt true

well thats just rubbish.

I don't know why you guys haven't had as much trouble as we hasve had up here but here are some things to consider:

* You guys have seen the same issue

All that was needed was an extra litre of oil

fair enough if you are happy with band aid solutions but don't try and claim there is no issue

* there is *far* more experience with proper circuit racing in NSW. Mark and I have been racing GTRs up here for 4 seasons, and sydneykid and those guys have even more experience. There is a world of difference between a 3 lap supersprint and a 12 lap race. There are no gtrs circuit racing in vic.

* may even be as simple as there are no big g, long right handers in vic, oran park off the bridge for instance is huge for surge.

Ever since putting in the trust sump we have had no oil pressure problems anywhere, circuit racing or at targa. This includes a 1 hour enduro at Oran Park where we ran out of fuel after 57 minutes racing but had no surge issues.

[R31Nismoid]

Its not rubbish far as i see it.

The problem is not due to the sump at all. The band-aid is spending money on the sump when its not whats causing it.

Its to do with the head retaining to much oil... hence the overfil counters it on a stocker motor to last out a 3-4lap sprint.

The problem arises when people dont overfil, after some laps there is not enough oil left down below and low-n-behold it does a number on the bearings.

If you have the motor apart, do the head right and there wont be a problem. Just over fill it and run around happy as a pig in poop.

That many cars that are doing some scorching times have no issues...

But then most of them have been loved by Racepace

[r33_racer]

haha in qld if you do the baffled sump and oil control mods...you still spin bearings. DSS now for us up here. (Dry Sump Syndrome) not even gtrs either, just gtsts.

[R31Nismoid]

hahah

they suffer for SGS

lol... randomness

Hay shed at P.I. is a 180+ right hander in a car with good rear end grip.

I have a 1994 R32 with a stock bottom end. So far 7 events with oil filled to the top of the dipstick "hump" with Castrol Edge 10W60, so good. Have had 3 20 minute sessions at P.I. with no issues.

That said, when the engine comes apart for a refresh - every manner of oil control issue will be addressed.
