It really doesnt matter how good the relationship is with SAPOL and who knows who..... The fact is organised car cruises represent a gathering of people with generally illegally modified cars that are getting together to show each other their cars, talk cars, and finally drive their cars. Rarely do people with totally stock Hyundai Accents go to these cruises because they dont give a damn about their cars... To the Police organised cruises represent a rare opportunity of shooting fish in a barrel by ridding the roads of a potential menace, congestion, and anti-social car behaviour. While this might sound damning I cant remember being on a car cruise in the past 20 years where multiple traffic violations havent occurred. Now be honest with yourselves and who hasnt given it a squirt alongside their mates on a cruise, thats part of the fun, right? And so is SAPOLs determination to stop these gatherings and the resulting activity. You drive an illegal car, you invite the Police to your cruise, they will defect you. They see roadworthiness as your safety as well as their job, and really they should have explained that you. No amount of brokering deals will ever change this, its all been done many times before, and will be again in the future. The result will always be the same. Enjoy your modified cars, but be sensible enough not to do it in groups if you dont want to be defected. Go for drives meeting up somewhere out in the country, and then keep it to a minimum. Dont drive through built up areas or the cruise strips attracting unwanted attention. Rather than trying to change the law, its time to change your thinking....or keep playing the defect game. As one old Copper told me in the past "Try as hard as you want mate and put it through stock again, we will just keep pinging you every time we see you....and we ALWAYS win. You will get sick of it before we do". Know what? He was right

I hate to break it to you Helious, a V8 Supercar isnt the same as a Commodore you see on the street with a bit of tuning. Its a million dollar purpose built race car that these days is lucky to share one or two parts with the road car. An R35GTR on the other hand is an ADR compliant genuine road car....or at least ours is I hope and pray people dont start pulling these cars apart, putting shit mods all over them and destroying them...thankfully those that would do such things are probably seven to ten years away from funding ownership....as happened with the R32 GTR, took around till 2000 for some to ruin them with crappy dumb mods when they were released in 1991. No need to panic yet then

I didnt know/care you had oil cooled turbochargers, you added this good on you. We have 2 x GTRs with oil cooled turbochargers the slowest having run 9.5 @ 149.5mph, so there is no doubt they work. In the old days oil cooled turbos needed to be cooled down to stop the oil carbonising/coking and binding the rear seal/blocking the oil feed. With todays modern synthetic oils this is a thing of the past (unless of course you use Homebrand in the engine). Dont worry about hardening the feed lines on a Skyline, they are steel - the harder the better There endeth todays lesson. P.S. I am old I treat everyone as though they are younger than me, as they probably are

If you need a Turbo Timer to protect your turbocharger(s) you shouldnt own a turbo car. With power comes responsibility The best Turbo Timer is your head or the grey stuff in it.....

Funny thing is Turbo Timers havent been required on Nissans since liquid cooled turbos were introduced....In other words if you drive your early model ET Pulsar hard then maybe, other than that they are dangerous wank with no fit purpose other than to keep Constable Neil busy

You should actually try that, I know I have, and the answer isnt clear cut at all....but this is the internet. Even better is the Hyundai Excel early model style notchy vague cable gearshift in the 911. A work of art indeed

Whats more surprising is the 11.6 from that same car 'dead stock' with no Launch Control at all When I refer to 'hook' its hook-up off the line....

LSX-438.... The new launch control ran a 1.69 60ft on the Dunlops, its good, but not as quick as the 1.44 60ft generated on the old Launch Control Feeding in the clutches at 3000rpm with the traction control working isnt going to be as fast as sidestepping the pedal at 4500rpm which is what the old LC system did. Not many of these guys understood that unless they made the car 'hook' that axle tramp would destroy first gear....now its been made 'soft' there will be no such problems

You want serious clarification? Then here's the facts straight from DOTARS the govenrning body. If you modify your car in any way shape or form from the original test vehicle specification presented when compliance was granted for your series (Stagea, R32, R33 etc) then technically you are in breach and the vehicle is instantly defectable. This isnt something special for Skylines or imports but for any car wearing a number plate in the majority of the states and territories this country. This is Federal legislation, so winning over the hearts and minds of the local constabulary isn't going to change a thing. They have a job to do, and if you are in breach, then you will be pinged. It really is as simple as that. Remember the onus is on you to prove that the car complies. So how to do this? Align yourself with a workshop that has a working relationship with DOTARS approved automotive engineers. The workshop performs the modification to your vehicle, and the engineer - for a fee of course - undertakes accredited testing to put forward the supporting paperwork to Regency Park here in SA showing that the relevant ADR standards are still met with the modification(s) in place. For example we (Willall) put in an emission testing facility using the same standard used at Regency (IM240) at great expense, but its a piece of equipment that allows us to mirror their results and give supporting evidence to an engineer. We also use this equipment to perform initial emissions testing on our GM Twin Turbo systems, some of which we have now had fully ADR approved and road legal on a 'type' basis (i.e. you buy a VE Commodore fit our kit, have an engineer check its the same as our original test car, and voila legally registered and insured) What is needed then - and always has been - is not so much a truce with the Police, but a more responsible and informed approach by those that are modifying their cars. All of the facts re modification are there in black and white so there is no excuse....and personally although this sounds a bit harsh, the Police are performing a public service by handing out defects, some of the cars we see with snapped aftermarket coilovers, dangerous chassis/brake mods, and covered in second hand cheap junk is alarming and disturbing at best Realise if you want to do it right, then be prepared to spend the money on engineering. If you dont want to do it right, then bloody well keep under the radar and avoid activities like organised cruises, which make mass defecting on non-engineered cars like shooting fish in a barrel. This is the way it is, and just as importantly the way it has always been.

This is a great forum, and I have been a member longer than most Problem is there doesnt seem to be too much to talk about in SA anymore when it comes to Skylines. Spotted and wasting time threads about nothing seem to dominate the headlines with some defect banter for good measure. A lot of the guys and girls with big combos wont post for all sorts of reasons, and some of the newer members - no offence - have nothing worth posting about. Its a Catch 22 and someone needs to step up with some worthwhile content

I only compared stock car to stock car, no point in anything else. Stock GTR to stock 997/996 - GTR is quicker and faster everywhere. Thats a fact

Not so much the size of the brakes on a Porsche that make it difficult to pull up, but rather the lack of direction stability and balance, with the front of the car pattering around on the road due to the weight distribution issues these cars face. Having said that the only Porsches I have track tested are the 996TT and the 997TT (which actually seemed to be even more unstable than the ealier model). You will surely be blown away after getting out of an old fashioned AWD like the 996 and stepping up to the R35. The difference on a race track is night and day.....plus many, many seconds

The COBB AP does indeed read and clear DTC codes, understanding why the car generated them, and going about a fix for the problem is a whole different ball game though, and thats where experience with the cars comes in

You need to speak to the right people Turbz 13 We have between ourselves and our immediate customers 1 x Twin Trust T67 GTR, 1 x Twin Trust TD06 GTR, 1 x Garrett TO4Z GTR, 1 x HKS T51 GTR, and the list goes on....and on. There are plenty out there, but you more than likely wont find them playing "Look at me!" on forums Pick a professional GTR proven workshop with real runs on the board, ensure you have an adequate budget, and go speak to them

I like Porsches, they make good braking markers on track days

We will more than likely enter the Willall Racing R35 GTR in selected parts of this series Entry forms are downloaded

The issue of maintenance for the JDM R35 GTR is now something we (Willall Racing) have covered. Having been in the same position of the others here with JDM R35 GTRs our first point of interest was to establish an independent R35 GTR service centre that could perform all of the routine maintenance these cars need and then take it to the next level using better quality lubricants etc. (most of you would have heard of WR35TM by now). While our R35 knowledgebase will surely continue to grow over the next 12 months, what we can tell the JDM GTR owners is this - - These cars are very reliable - Most of the fittings interior and exterior are high quality and not prone to failure - Not being locked in to an exorbitant priced manufacturer service program gives you options - R35GTR will lead a healthy and happy life if serviced carefully by an organisation in the know - It does not cost an arm and leg as some would believe. Having said that, change all your oils now. The factory GR6 transmission fluid is not a good manual transmission lubricant that makes metal in the transmission from day 1 The engine oil 0w-40 Mobil 1 is too thin for our climate, and your useage will be high, around 1 litre per 3000km. Note it goes dirty almost instantly - pull out the dipstick and have a look for yourself! The differential oil BP/Castrol SAFX performs well, however it tends to get overheated in the front differential. There are indeed better products.

About time you got into something decent LSX-438 Our sources indicate some of those dropping off the list have been concerned by the 'softening up' of the Aussie model, with Launch Control removed, and the Bilsten Damptronic system recalibrated to make it less harsh, but possibly ultimately slower Still, the car has greatness built in from factory

Here is a great example of what you can do with a 3 litre RB series engine if you set it up and tune it correctly across the whole rpm spectrum, optimising for Mean Best Torque. The interest to be taken away here is not in the 652rwkw (875rwhp) but in the difference between roller measured torque and derived torque calculated back from the engine rpm Pure or roller torque is in the region of 1420Nm from 6000rpm which gives the engine plenty of pull towards the redline, but is hardly an accurate indication of actual torque. Now we bring up the derived calculation, which shows a closer and more accurate 880Nm. You can see there is a very big difference between roller torque - the way some here have been looking at their figures - and derived torque. I think actually looking at this we have a new Skyline torque winner as well We should have some more figures very soon from a similar engine and turbocharger package we are engineering that will achieve the 1000Nm derived torque figure. As some have been heard to say, 600rwkw, its yesterdays 300rwkw

I will get off my backside and print a pressure drop graph we did on a GTR for you tomorrow Then you will see how useful it is

Waves in dyno runs are generally only ever the result of a control system problem inherent in the dyno. If not you would feel them on the road. The way to properly test whether an intercooler is too small. Its very simple, and doesnt - much like your engine - take into account anything other than the pure physics of the situation - plug a pressure feed in each side of the the intercooler. The Mainline uses both its pressure sensors to then calculate a channel called 'Pressure Drop' which graphs against power or other data channels to show you exactly how or even if the intercooler is holding you up

None of those torque figures are accurate unless an inductive RPM pickup was put on the engine, or the derived rpm generated from wheel vs roller speed (not quite as accurate). If you have Killowatts at the Roller and an Engine RPM figure, you can of course calculate a "Derived" Torque figure, remember if you have any 2 of the 3 components of Power (HP)= (TrqFtlbs x RPM)/5252 equation the 3rd can be calculated. Mainline dynos do this very accurately with their excellent RPM pickup, but like any top level chassis dyno they give Derived Torque which is simply Torque at the Rear Wheels (or front or all 4), so essentially it's the Flywheel Torque minus Driveline losses. If you want a torque figure calculated correctly for any of your cars let me know and I can run them with the RPM pickup in place and generate true derived torque for each vehicle. At least that way you can make accurate comparisons Note when an inductive pickup is used to measure rpm on the older version of DD software that most of you seem to be posting the torque is represented as iNm rather than straight Nm to let you know its been measured with an inductive pickup

Sure, Ive known Sean from Boostworx for years, and we get on no problems. Since RH9 ran its 9.6 @ 150mph in full street trim (save for some MT radials) a couple of years back its been retired from drag race duties, and sees more time at Mallala, where its a real handful and plenty of fun

Whats this with the SA Skyline scene letting a Supra beat them? Sounds like its time to brush off RH9 and show some of the Toyota fans what > 550rwkw looks like...on Ultimate with no NOS

Pity about the loss of boost Blue32 We tuned Andrews car, strapped correctly, with 20psi boost on our Twin Retarder 1000kw Mainline Chassis Dyno, and generated a fairly comfortable 401rwkw @ 7550rpm. Would be interesting to see the dyno sheet from the competition to see if there was any comparitive wheel slip involved, and the actual setup of the dyno in regards to Baro, Shoot mode selected etc Heres is our raw data -
