If you're planning on getting the Phillips blue globes and expecting them to be blue - don't. I've got a set in my car and they put out a nice white light, and they have noticeably improved visibility, but if you want blue, then they ain't got it Mind you, I don't think that's a bad thing

Sounds like a classic case of the ECU saying "WTF is happening to the mixtures??". What's probably happening is that it's using the fuel maps in the ECU, and when the oxygen sensor starts returning some absurdly rich numbers, starts winding back the mixtures until it idles. Stupid question, but you DID retune the car after making the changes? If the AFM and injectors have been changed and the tuning remains as it was before the changes, then the maps in the ECU will be basically useless. The fuel will be too lean and, at best, the AFM readings will be out all over the rev/load range. At worst, the new AFM will have a completely different response curve (if that's a term you can use to refer to an AFM ). If I'm completely off the mark and you HAVE had it retuned, I'd be taking it back and having them tune it again. Another option is a leak in the intake piping, sucking bucketloads of unmetered air into the engine and thereby making the mixtures much more lean than the computer thinks they should be. A bad thing all round, and could cause the problems you describe. How does it run on the move?

Erin, that's one of the best bits about spectating - the fact that they're "real" cars. Guessing times can be difficult though... I've been proven wrong by around 10 seconds before, with those damned small block V8 engined LiteAce vans and SR20 Dattos with crap paint

The race entry fee covers the driver and one "pit crew"... so spectating is FREE if you can manage to score a spot in a car that doesn't already have passengers. It only covers one passenger though, anything over that and you pay for the extras. I think it's something like $20 each for spectators (except for the one you get in as pit crew if you're racing). I dunno the exact amount because it's been a while since I've been out to the drags and haven't been racing Erm, hope I've explained that properly But it is a pretty good setup

I can't think WHERE George might have lost time...

Was a fantastic day, thanks to all involved (especially the Sideline guys and slip). Gary, wtf are you doing posting on the forums, you have some video to sort through

Sorry for the delay - I've been without a computer for nearly a month and have only just got it back... They were incredibly hard to get, the ONLY place that I found with them in stock was Moorooka Nissan (in Brisbane). From memory they were something like $100 for the two?? Can't remember. A small pointer though - get hold of a bearing press BEFORE you start this job. Getting the old bearings out, particularly if one of them is badly scorched, can be a right pain. What should have been a coupla-hour job tops turned into about four hours...

A mate of mine who drives an MX6 Turbo was pulled over one night by a cop. The cop went over the car making comments like "ooh, no AFM, what computer are you running?" and "that catch can is illegal", "nice dump pipe" and things like that. He seemed to really know his stuff. He even did a line-of-sight test on the pillar-mounted guages (they passed), rather than just looking at them and slapping a defect. My friend ended up having a bit of a chat to the cop who apparently is into hipo cars himself and is a regular at the drags and drove away with a list of things to fix - atmo BOV, catch can and the exhaust being too loud - but did not defect him for anything. No fine, no points, no conviction. Legend.

Another vote for Rob Bliss here. His shop did my exhaust about two years ago and it's still going strong Only change needed was to cut the centre muffler out as I wanted more noise, and I had the guys (at a shop in Toowoomba, where I was staying at the time) weld in a couple of flanges. Slightly OT, but they also made me a track-only pipe that eliminates the cat and exits under the passenger seat, it's really loud I dunno whether it makes any more power but geez can you hear the turbo spool!

SVD, you'd pretty much drive past my place on the way out there then if you're at KD... I'm about a block from the bridge that heads into the CBD Might head out for a look but won't be able to race.

Might be interested if the budget allows (I have a few large bills coming up). Might actually take the 'line down this time, the bike's been down the last two trips in a row I may also be able to convince a mate or two to come along (including one with a MkII Supra with 2J in it )

OMG I wonder if some of you guys know how up yourselves you sound... no offense, but read back some of these posts and substitute 'skyline' for 'Commodore' and I'm sure you'd think they were a bunch of pompous, stuck up so-and-so's. Although I'm sure not all of it was intended to be read this way, it's easy to do so, so just be a little more careful. DCIEVE et al - couldn't agree more.

1980 VC Commodore. Bought it with a very rooted 173 in it, ended up with a blue 202, lumpy as Crow Cam, 450 mechsec 4-barrel holley, extractors etc. It got 20l/100km, was lumpy as anything (couldn't get it to idle below about 1000rpm, cam started to come in around 3000, redline at 5500) and the cops loved it, and if I caned the crap out of it, it would *just* keep up with a stock VLT Next car was the '33 in 2000, then I bought the bike in May last year. Turbos are good, but just the thought of bolting one onto the bike scares me

They're not all dickheads. I've had a few good runs with HSVs, both in the car and on the bike, and every time they've waved or smiled, had a chat or whatever. I had a run with a Clubby R8 one time, and it was quite a close race. He got me at the start (rolling start, NA will always have the response) and we were basically side by side the whole time. I pipped him by maybe half a car length before I hit the limiter. Result: Thumbs up from both of us and a few compliments when we met later. I also had a play with a 300kW Monaro on the bike while heading up a mountain a couple of months ago. It was close in the corners (cos I'm a wuss ) but I flogged him on the straights and under brakes. Result: A big smile, a wave, and a nice little drift when he turned off at the top of the hill, sweet Actually, while I'm thinking of it, does anyone know of a really quick black R32 GTR in SE Qld? My brother was riding my bike on the highway and the GTR decided he wanted a play, so off they went. By the top of second there was maybe a car length or two in it - the bike won, but not by much! At a guess it was somewhere in the 11s, and it was shooting flames out the exhaust and everything I dunno who owns it, but he was an asian guy and apparently gave a wave and a smile when he pulled off.

SIK I have been for a walk through an intensive care unit. Actually several of them. I work in the public hospital system so i see my fair share of aftermath damage. I am still more than happy to ride a bike - going on the numbers (I have run these myself but can't divulge the figures) you are more likely to be hospitalised if you drive a car instead of a bike. Admittedly when the bikers come in they're often in worse condition, but the majority that come in were doing something silly at the time Russ Yes, you can get a car to beat a bike. I'll bet however that the Supra probably had the best part of $100k spent on it and the bike might have had a K&N and end can. There are VERY few cars that will keep up with a heavily worked (ie turbo) bike. That's not to say the Supra is any less impressive (it obviously hauls some serious arse) but it is annoying when someone comes out with a statement about how a massively worked car has beaten a stocker bike. inark Those are some of the more 'sane' videos I have

Also note the shortshift into second at 70km/h... and how cool is that Kwaka dash?

How about this? Because I love you guys so much I'm hosting two video files. Hayabusa 0-210km/h. It's a 14 sec video, some of which is slowing down and stopping, and some of it is... well, you get the idea http://members-central.optushome.com.au/co...ech/Busa210.wmv Kawasaki ZX636 (yes, 600cc). A quick squirt to about 230km/h from memory. http://members-central.optushome.com.au/co...bmech/ZX636.mpg I love watching these, how quick do those numbers climb? If the owners of either video would prefer for me not to host these then please email me. I made an effort to find them elsewhere on the net and post links to them there instead but without luck. Edit: Aah crap, no HTML...

Can someone explain to me how adding a restrictor to the wastegate line can *limit* boost rather than raise it (or at least postpone it)? This is a serious question - as I understand it, placing any restrictor in the wastegate line will slow the response of the wastgate actuator in relation to the manifold pressure. Obviously if some well-respected people like Mark Tillbrook are saying that doing nothing except removing the restrictor will give you more power, then there must be some truth to it. Can anyone clear it up with a solid explanation? JAGR33 - sounds like your car is a bit of a weapon Not disputing your claim of a power/boost increase, but I would suggest that much of this increase came from the cam gears. It's amazing what effect dialling in the cams has on not just the running of the engine, but also the building of boost due to different valve openings. Also, if the exhaust and pod were put on at the same time then they would also have a sizeable impact on boost. At a guess, the reason so many people recommend removal of the restrictor is because it makes it difficult for an aftermarket boost controller to have "full" control over the wastegate - a case of too many cooks, if you will. On a stock engine (or at least one with the factory wastgate system in place) I would leave it in, or risk losing boost response. Again, correct me if I'm wrong and you can back it up with a solid explanation of why. I'm not going to dispute the presence - or lack thereof - of a restrictor on a non-GTR because I just don't know, suffice to say that if your car has ever been in need of a wastegate line replacement, I dare say it was replaced with standard vacuum hose, without a restrictor, as it'd be cheaper and easier to get hold of than the genuine Nissan item.

Mick/Werdest - OK here's my best time, but don't laugh [email protected] (from memory). I am far from the best/lightest rider though (don't like to launch hard cos I'm a wuss and it kills the clutch) - a guy with bigger balls and a nearly identical bike to mine and who weighs about 40kg less ran 10.58@134mph. The potential is there but I can't get off the line. I dunno what track is close to you guys, but at Willowbank there's normally a fairly decent contingent of bikes at the Test n Tunes. You can see at the drags how many riders are slow off the line and only start really putting the power down 50-100m into the run. A few weeks ago at Willowbank a GSXR-1000 ran a 9.99@141mph, and not long before that, a Hayabusa ran 9.78@146mph. The bikes can definitely do it, but not every rider out there can. On a side note, my brother's CBR250R (~19,000rpm ) ran 14.7@92mph, and I've seen an RGV250F dip into the high 13s, so even the 250s have some poke about them. Most current 600s will run mid 11s (11.5) with the exception of R6s, which will run low 11s with a good rider, and very high tens with a fantastic/light one. Then there's the Y2K Superbike which runs 9.6@160mph but that's a different kettle of fish Russ, I wish my bike weighed 100kg too As I said, it takes a rider with massive balls to get away from a car in the twisties. It's also far more physical, having to climb all over the bike to get the weight balance right, pinching the seat every time there's an imperfection in the road. Don't forget that the vast majority of people would be far quicker in their cars than their bikes when it comes to the twisties - you feel safer to push the limits because you're in a cage, and if you're on a bike and lose it, let's say you don't just spin out... It is always good to beat something that should/you think would be quicker though, congrats on the Reefton Spur thingo, sounds like fun Don't forget that the vast majority of bikes you see on the street are bog stock (perhaps bar an exhaust and air cleaner or something). If you ever hear a big bike with a BOV, don't mess with it at anything over 100km/h There are guys getting 450hp out of 300kg (with rider) road reg'd Hayabusas...

I don't think you're dazzling anyone with your intelligence. Ignoring and subsequently attacking people with an incredibly simple request is not a good way to make friends in here. Anyway, getting back on topic, a restrictor in the wastegate line, particularly after any boost controller, can only slow the passage of pressurised air, thereby causing boost to come on harder and possibly with a small spike. Surely removing it will slow boost response and remove any short spike in the boost curve? So, without some form of EBC or at least a gated bleed valve, the car will feel more sluggish. With an aftermarket controller, you don't want a restriction to affect the function of the controller so in this case, go for it and remove the restrictor.

Yes, I had a spare five seconds to look up that info. It shows a huge amount of immaturity on your part for attacking people who have a simple request, like pressing ONE KEY on your keyboard. All of 23 posts to your name and already stirring shìt.

Race a bigger bike... even my 900cc bike finishes the quarter mile at around 130mph. GSXR-1000s and Hayabusas and the like will do it at over 140mph, and in under 10 seconds if launched hard, all for less than the price of a decent R33 GTS25t. And if you think that it's fairly close off the line (it is VERY hard to keep the front wheel down while launching, and many bikes are governed in first and sometimes second gears), try going from like 120km/h up. Bye It takes a VERY serious street car to come anywhere near a stock litre-class sportsbike. Corners are a different matter though - it takes a rider with humungous balls to catch even a reasonably quick car in the twisties. Good work with the Boxster - it's always nice to flog someone who thinks they're so much better

Bet you were popular...

SIKR33 On the internet, as in real life, there are certain rules that people should follow - in this case, they are referred to as 'netiquette'. Here are a couple of links I found by typing 'netiquette' into Google: http://www.dtcc.edu/cs/rfc1855.html http://www.albion.com/netiquette/ You will note that typing with caps lock on, apart from being annoying to read, is considered as shouting on the internet, and can also be considered rude in some circumstances. Noone is suggesting that you're an idiot or anything because you use caps lock - in fact, I think most of us appreciate you taking the time to post up little tidbits of info like that in your top post. It's simply more pleasant to read something that's written in lower case or, preferably, mixed case (proper capitalisation). Please don't bite someone's head off because they have the nerve to offer constructive criticism. Please, PLEASE, turn your caps lock off. Think of it like the indicator on your car. It isn't absolutely necessary to use it to go places, but it sure as hell makes the trip far more pleasant for those you encounter along the way.

My dad's Patrol ute with bullbar, spotties, 6" lift kit etc is great for this. I suppose a lot of people don't want it in front of them, so they pull the "speed up and fill the gap" trick as soon as the indicator starts flashing. So you just keep turning... and turning... and smiling... and turning. Most people get the idea pretty quick but I've been within inches of a couple of idiots - but they always move in the end ALWAYS give a thankyou wave with a big smile afterwards.
