Come on Troy - how many times have you seen that happen & go unpunished? It is Webber's stock move most of the time & the rest of the field for that matter.

I was talking to a driver from the vintage car club. He said hydraulic brakes were for pussies. Going massively off topic and talking about the wing I have a few assumptions/questions: I assume the general characteristic of the R35 is midcorner understeer. That being the case how does an increase in rear downforce help anything? The simple answer would be to see a trace of the lateral gees versus distance (or time) to check the shape of the graph or see it plotted versus steering input for a given speed range. Anyway the product looks good. I just wonder how people pick up seconds a lap when I bust my arse to pick up a tenth. It usually means the driver is having more of an influence than the engineering. Typically less experience drivers go better in cars that understeer than with the sort of neutral/edgy set up you need to squeeze the last few tenths out of a lap time.

Depends on what/who you believe. Seeing as you are a McLaren fan - any thoughts on the M8?

It wasn't dodgy. Sure, it wasn't the greatest Williams ever but it was a combination of tragic circumstances rather than a "dodgy" design. Williams Renault's won multiple world championships- both drivers and constructors. And the BTCC for that matter.

Well Williams Renault has a certain ring to it. As does Lotus - Renault. In black. With some bloke called Senna driving. Your Polish mate in the Renault is doing alot better than almost everyone thought this year. His team mate doesn't suck teh balls to anywhere near the extent I thought he would, come to that. Bring back McConville I say. The yocals bore me to tears. The Brits are their usual one eyed selves. Still it is better than Murray Walker when Mansell was around.

The RB26 already has a means of scavenging the blowby gasses that accumulate in the head/block. It is the pipe & PCV (valve) that runs from that back of the inlet cam cover to the inlet manifold. Opens under vacuum (ie closed throttle) & sucks the stuff out into the motor & hence out the exhaust. On the other side a line runs to the suction side of the turbs (from memory). It is this one that sludges up your intercooler & has oil dripping out your BOV's. Alot of people block both up when fitting a catch can - not the way to do it at all. For what it is worth (not much) I have run an R32 R at Wanneroo & elsewhere for some 5+ years. On R comps. Originally an 89 & latterly a more recent model. Other than filling the thing up with 5 litres of oil I never had a problem with the 89 version. For the 94 I had fitted a sump baffle & a Nismo oil/air seperator. The only problem I had with that was caused by a stuffed PCV. In short it is not the problem alot of people make it out to be. As for failed oil pumps I strongly suspect alot of them can be traced to stuffed harmonic balancers.....Yes the 92 & on models have a better oil pump drive which is absolutely worth doing if you are up to your elbows in RB26 entrails. Yes the oil restrictors in the heads are worth doing if the head is off. But neither are mandatory.

The Toleman was actually pretty good. Brian Hart did good engines & from memory some hack called Rory Byrne penned it. The point of my analogy is that there isn't much to be gained in imagining if whatever happens. Anyway your hero, Schumacher, regularly would aim his pole sitting car at an angle & then drive the other front row starter toward the pit wall. I distinctly remember him doing it to his brother of all people. If you really want to imagine something try a big accident infront of twenty other cars all with full fuel tanks & cold tyres. Into the first corner of a GP....At the German GP in the early nineties something similar happened. On the upside Tyrrell got some points that day... Breaking someone tow is not amateurish. It is just something else race drivers do. Or atleast should be allowed to do. It isn't the greatest display of racecraft ever but I don't think anyone is saying it is. What I tried to say was that good racecraft is a large part of what you want to see at a GP. The FIA are systematically fking that over. As for Lewis (or any other driver) being a brat. Well to be honest I don't know that many well adjusted twenty something year olds with legions of fans & millions of dollars. Ofcourse they are selfish, self absorbed & maladjusted. Fk I would be if it were me. Probably already am. Very few top level sportmen are well adjusted. They are intensely competitive for a start which usually means they are pretty damn selfish. As for the Renault - for all the negative comments about their engines they can't be all that bad. Maybe running with less fuel is better than with mega hp. The Cosworths are really struggling & their consumption is reputed to be crap.

I ask you this: Imagine if EVERY one of my Aunties had a pair of bollcoks. Then they would be my uncles. Which if you think about it is also completely irrelevent. The rule was put into to help clean up overtaking rules. It appears to have been extended to now stop the lead car from breaking a folowing (as in behind, as in not next to or infront) cars tow. If you check the results from Monaco in 1984 you will see that another driver was closing down Senna. Racecraft in that race was best defined by Nigel Mansell stuffing his (leading) Lotus Renault into the wall & then blaming everyone/everything else instead of his own stupidity. Now that is RACECRAFT.

Nor is the answer to the lack of overtaking to make the bloke in front responsible for letting everyone through. Homo (or anyone else in that position) should be making it as hard as possible (Within the rules, obviously) for the bloke behind. That is his job, afterall. Remember Hamilton didn't just invent weaving on the straight. It isn't terribly effective, anyway.

Well I can't argue with your Oran Park thing but I would suggest the straight at Sepang is a little bit wider. My frustration is that these days when anything half interesting happens or it half looks like a driver showing a bit of race craft/interest the FIA jumps all over it & the story becomes one of fines/sanctions/warnings, instead of about racing. If you take all the bullsh!t the FIA/stewards have been involved in out of F1 in the last few years there is really precious little in the way of highlights. We now have these god awful ugly cars with all their parameters supposedly set up so they can overtake & it is now worse than ever. Atleast Lotus outqualified Ferrari & McLaren.

Weaving on the striaght to break a tow has been going on for a very long time. It is quite different from moving about in the braking zone to make overtaking difficult. It was not dangerous to Petrov simply because he wasn't up alongside Hamilton. He was behind him - in the tow. Hamilton cleaned up his act by the braking zone - where Petrov nailed him anyway. It is actually an indictment on the state of F1 where a driver using an age old tactic is warned is such a pointless manner. There was nothing reckless, or even wrong, with it.

Well if you have a closer look you will notice the front end is running alot of -ve camber plus a bunch of other non standard bits. About four degrees. I could easilly make it look more "flush" by winding some out. Which was my point, really. You need to know both the wheel/tyre size, the ride height & the amount of -ve camber. They are all inter related. Best thing to do is to try a rim.

The dot 4-600 range of fluids is as good as you need & it is easily available. Try the Motul RBF 660 & even the PBR (?) stuff. The 600 is its (dry) boiling point in degrees F. Which is better than the dot 5.1 fluids. Hence there is no need to mess about with the 5.1 nonsense.

Import yourself some 2 piece project mu rotors - they are much better than the DBA 5000's (IMHO). They are lighter than the 1 piece rotors too. I am fairly sure you cannot get 2 piece rear rotors for the smaller size on the GT-R's.

0.7??? Maybe for a semi trailing arm rear with the shock just over half way along.....are you sure Roger has the right model Skyline? The shock is connect to the hub so hub moves 1mm, shock moves 1mm. Or a tiny bit more because of the angle it is on. So 1:1 sounds right to me.

At some stage a historian will be able to pin point the exact time owning a GTR turned into a pissing competition about how much rim/tyre/offset could be shoved under the guards. You are having troubles fitting the rims because they have too much offset & are an half an inch to an inch wider than they need to be. Not having a go at you but I get sick of people trying to talk up wheel tyre sizes to the detriment of suspension geometry & handling - not to mention tyre life.

A 17*9" +22 rim is a very good fit for an R32 GTR. I have that size on mine. They are CE28's which clear an F40 calliper on a 324 rotor. The thing you have to understand is that the amount of camber you run will have a big impact on how flush the top of the tyre sits to the guard. You can make just about anything fit if you run stupid amounts of negative camber. Also it is common for the rear guard lip to contact the tyre if the ride height is low - a 255/40 rear tyre in a Briudgestone RE55 will usually do so. As far as calliper clearance unless you can get a diagram of the wheel/calliper the only way to confirm it is to see it. Enkei are usually pretty good on the clearance but it can depend on the calliper alot too.

I understand your point, but I still reckon I would watch that.

Yes but Red Bull have a rather large income stream (ie those crap energy drink things) whereas Williams & McLaren (to a lesser extent) don't have much other than sponsorship. You need to remember the huge money both teams invested in their facilities. Williams in the 90's & McLaren more recently. The McLaren HQ is, by all accounts, breathtaking. The Williams one was, in its day, head and shoulders above anyone else. Actually if you look at the grids in the 80's you will see that more than half the cars were absolute rubbish. The best season preview assessment of a car I ever read went as follows: Eurobrun. Absolutely & totally shite. F1 has, in recent years, been much closer than historically was the case.

There is a slight difference. McLaren, Williams are private companies. Ferrari, on the other hand, used to run those FIAT stickers for a reason. Actually, on average, F1 is mediocre.

For my 10 cents worth you are best off buying a simple, finished track car & learning how to drive it. There is alot to learn. I mean alot. Whilst it may seem to be fun to build something you need to keep in mind you are going to be pushing it hard & therefore it is not something you necessarilly want to learn about spannering on. Anyway finished/running cars are very good value compared with most things you can build yourself.

Yes. Start by learning more about how suspension works. That isn't a smart arsed answer & probably not the one you are after but I would seriously suggest you try & learn about car/suspension behaviour as a start point It will help you get more out of what you have & better guide you on what to buy in future.

The F40's (like most stuff on SAU) came from Roy. They are a good calliper & take a pad from the 4 pot Brembos on the Falcons of all things. Makes me wonder if all those Brembos on Foulcans can be put to better use? The rotors are stock R33 gear, ie 324x30. Still trying to find a 345 rotor to suit & get bracket made. Project Mu don't quote the offset for their 345 rotor for the Nissan (Part Number FC44 N102A & FS44 N102A with the callipers dependent on which calliper). I found the bias to be a little too far rearward so I reckon the bigger rotor would be excellent. The issue(s) I had with the ABS ECU are obviously that the cycle rate is rubbish but more so that the damn thing doesn't appear to actually release the locked wheel when you are on R compounds. Maybe the line pressure is too high but it doesn't function at all well as ABS on the track. Makes me wonder why bother carrying it. R33 computers/ATTESSA looks like an idea. No need for the 33 V-spec stuff but if the povvo pack gear works on a 32 that would be excellent. Although having said that with the Ruzic controller there isn't too much wrong with the 32 ATTESSA - as long as it is shimmed to spec.....

Can I ask a stupid question at this stage? I have upgraded my brakes to the Brembo size (F40, Brembo rears & larger master cylinder). The ABS on the R32 was originally pretty ordinary. With the larger brakes it is even worse. Does the povvo pack ABS unit have enough capacity to release the large pistons on the Brembo callipers or do you need a different unit? I suppose the question is: Is an R32 V-spec ABS unit different to the poverty pack GTR version? A second dumb question relates to the Vspec ATTESSA unit rate. Can you sling in a later unit from a 33 ie up from 4Hz to 100Hz & does this affect the ABS??? Sorry for the thread hijack.
