From Russell's point last night which I think missed the mins actually... It's the 95dB days that are the only way. Most days being 75dB is a fair problem for those such people... And in the old penny-drop fashion explains why the 3-track challenge won't work to get those cars along as some of them are 75dB days. So needs a bit of a rethink in that regard.

All. There was a very last minute Motorsport meeting last night, it was good 14 odd people could make it with 24-48hrs notice. The point of the meeting was to go over some issues that have come up recently and not only to work through those but also get ideas out about what other options are out there. Currently there are a good 14-16 people in the Motorsport C/Ship, perhaps there could be more and ideas to help kick start that and other event options. Attached are the notes/summary of the evenings discussion. There was a good 1.5 hours of solid back and forth with a few outcomes for people to work on over the coming month or so and report back. Feel free to post up any additional other ideas here, discuss etc. If you'd also like to attend the next, post up as well. Likely the next meeting will be in around 6 weeks or so and with a bit more planning so people can attend if they so choose. Enjoy SAU Vic Motorsport Discussion.pdf

It'll be back in a new days or so, end of the week as long as Apple process the payment (you gotta pay, to keep apps live with Apple apparently). Nice shaft that one... Hopefully sorted end of the week - C is working on it!

It's there in Android... I'll get C to have a look.

Agreed on the officials front. Overall well run given group 1 cars couldn't manage to stay on the black Squires steaks for lunch sorted that out at least, delicious. I can understand financially to a point, track hire was 7k (obviously plus timing, ambo etc). There is viable and then there is overload... 127 entires x $205...

Josie was always the better looking one.

Should be more organised with garages next time so we can book them all together in a group of 6-7 in a row rather than 2-3 here, then 10 gap, then 2-3 more etc

140 cars... 20 on at a time, 7 groups Aye f**k... SAU-Vic booked half a dozen garages yet?

I must have done 400-500+ launches (limiter, 8200), semi comps, slicks you name it... 365rwkw, stock box no problem. Broke diffs though, and that was only while I had it... son of rajab knows what it had done beforehand. The key is having a good clutch to absorb a bit of it, Nismo fits the bill perfectly. This. I had Nismo, loved it. Others have Quaife, love that. Both work so much better than stock. It's a 6-7k job end to end if you are not DIY (front/rear diffs + full transfer rebuild). It would be more expensive if you have a R33/R34 with a A-LSD, but you don't so happy days. It will totally transform the car, you will not believe it even after you have driven it for a week as the diffs settle it just gets better! Definitely don't bother with anything else, gearbox or otherwise. Not needed, even when you break one - just put a $700 replacement back in there and off you go.

Yeah I realised after i posted you meant tonight LOL. Need to plan a bit better, but the offer still stands if a bunch of you wanna come down.

Happy to do another Squires Loft Nunawading night if you guys want, Mon/Tue/Wed - Throw on a blanket 20% off same as last time. Only problem I have is I need 100% definite/committed numbers as we are booking out even on Monday nights now.

To the original question GTSBoy hit the nail perfectly. The other problem the 7-blade wheel had, was compressor surge in the lower RPM on at least a RB25. I had one of these 7-blade devils back 8 years ago, they were called a GT3040 then, on a RB25 (tidied up head/ slight cc increase and that's about it)... And low RPM surge was a particularly annoying problem around 1900rpm. Tried to alter the tune a few times and just couldn't get it right and ended up going RB26 due to a few factors. Still made good power, 270/280rwkw on around 17psi so similar to you, much more boost didn't net a whole lot of gain on PULP however. We did crank it up to 24psi and put 104 Sunoco through it for an Autosalon haha, walked away with 369rwkw so it still performed at higher boost levels but it required the fuel to do it.

Yeah I know, it's overall - all quite odd indeed.

Proof that you've actually been scammed. Unfortunately a lot of people 'say' they have been scammed but digging into it, that's not the case and goods turn up etc. So it's not an open slanging match based on he said/she said. copies of PMs, bank transfers, the user in question (we do some checking/question asking of ourselves) etc etc. basically - everything you have.

The thread creation date isn't the last updated date for the thread. I updated it late last year actually with another person. So as people let us know, with actual proof, then it gets updated. Most of the time people have no proof, so we can't update it.

Have you checked the ID tags to confirm? Always a good place to start

Yep, no point really at all. Especially with built motors, different flow rates, compression... The works.

I'm yet to get a chance to drive Paul's car with the Quaife front to see how it differs to the Nismo... But yeah for a budget that would be a good option with a shimmed rear, you are luck you have a 32 - makes it much cheaper than a R33 Vspec lol. Once you do transfer case F/R diffs - you'll soon see you probably wouldn't even go and get a controller... You will seriously love the improvements proper diffs give.

Massive +1 to all of that. "Oh hey I ran a 9 sec pass"... but it actually took 3 seconds to build boost on the brake to get that 9 sec pass and the car that runs 12s passed the line before me. Works great for street light warriors though, you get a good 5 seconds to sit on the trans if you can read traffic lights well lol A properly set-up car, won't need to worry about that. There was a VL turbo down here actually racing in S/S - That earns massive respect. But yes, manual is going to make it had. You really need to have an anti-lag type set-up so you can build boost and leave the line with as much power as possible. Only problem - anti lag puts quite a lot of stress on parts. Nitrous is another thing to perhaps consider, as is a great tyre/rear end setup and if possible - staged launch control

Not if it's running 21psi, you have the airflow for the power. You can tune around the AFM limit to a point from a WOT point of view, I had 340rwkw out of -9 using the stock MAF (but that's another can of worms not worth opening). Somethin just does not make sense really.

The cat might also just be failing? Depending on how hot etc, not all CATs last forever. I mean one brand had a LOT of failures in the latter half of last year, so anything could've happened... But you kinda do need to drop the exhaust to work that out Hell it might even be the exhaust itself, all that gets confirmed by taking a couple bolts off - Is it a Jap one?

A complete goose. And hence, you never take the car back and see someone else! For 21psi with -5s... You are sorta missing 50rwkw still. You can go the usual dyno variance 10/15 here there whatever, but 50 is a bit.

Most certainly they do. Firstly, forget -7s. You want -9s and you can make 320-340rwkk. -7s and -9s both drop boost in upper RPM as they are only small turbos, they simply dont flow wild amounts of air. You look at the torque/TN graphs and they just die in the ass above 7000 so you are revving for nothing, better to shift a gear and get back into the meat. The reason is they tend to make no more than 16-18psi by 7500rpm if the motor is efficient. You can smash out 22-24psi through the mid range though so it's going wild by ~3500rpm torque wise through to about 6500rpm but you dont really 'feel' them falling over till 7000rpm and above. Don't forget it's not just about RPM. The smaller -9 are coming on hard around 3300rpm-7000rpm vs a -5 which is 4000rpm-8000rpm. So your power range really is not altered, but people forget that and sometimes swap to -5s and go 'the car has so much more pull above 5000' which is just a case of they want a car that's going to pull to the limiter rather than shifting earlier to compliment the turbo setup being run. Also the other factor is the transient response, in out of gears etc. I've had them both and I can tell you the -9s will come back up onto your 20psi faster than -5s if you are under around 4500-5000rpm. So you need to be giving it a gutfull everywhere with the -5s... You should go in a car with -5s and -9s and see for yourself what it's like in/out of gears - For what you want 80km/h-150km/h stuff, which is what I did a LOT of in my R33 GT-R - You want the smaller ones. And yeah, forget those f**king Tomei manifolds. Just get a set of cam gears, heavy duty actuators and a good flowing 3.5" exhaust. Spend the rest of the money on suspension/brakes and - do the FRONT and REAR diffs, for hillclimbs, you will never regret putting decent diffs in. The pull you will get is just unbelievable compared to how bad the factory stuff is (remember, 15+ yrs old).

Closed/Edited. Sounds like a trader ad. If you wish to trade, you are required to pay like everyone else... This includes trying to be sneaky and using the PM feature.

There was only 40 spots available via WRX form when it went up. Even less spots left now too, 3 at this point
