The best sprint & hillclimbs are in the Speed Event Series. www.speedeventseries.com The WASCC is currently running a summer hillclimb series. No Limits do a Thursday (?) night thing and can have driver training at those events. If you want driver training the WASCC periodically do exactly that. Worth keeping an eye out for. The McRae series is really good but I wouldnt recommend it for beginners as there is plenty of hard stuff to hit if you get it wrong. Also the AHG centre (RAC centre now?) have series and they are good events. Be well worth looking for. If you want cams affiliated clubs try the WASCC (Wanneroo - more expensive but you get free entry to such things as the V8's), the WACC, The Collie Motoring Group (Although I am a little unsure of what is going on there), No Limits, I think even Antilag are now Cams affiliated?

I had a look at the five R's at the last round of the SES - Wanneroo last year. There was five cars and five different catch can set ups and five differing states of engine newness. But none of them had issues - then again none of them had the big oil pumps..... Don't really know any of the cool kids over at Antilag and havent been to a no limits thing in years. Cheers for the tip I'll have a scratch around to see who may have what. Cheers. Sounds a bit like a Nismo separator plus catch can. I have the Nismo bit atleast.

Where does the head feed get its feed from?

Not that I know of. But I reckon blowby would have to be massive to get the sort of mess you see in the photo & in anycase I have no reason to think there is any worth the name. The photo was after three warm up laps & three fliers at Wroo. The motor was built with extra care verging on paranoia and run in on the dyno, then run in some more on the road. As I mentioned earlier it is fine on the dyno. Nothng coming out of the breathers. Take it to the track and there is oil in abundance. My thought is the extra time at higher rpm is allowing oil to accumulate in the head - add some cornering gees and you get a mess. Am contemplating running an N1 pump as a fix. But only if I cant nut out a better solution for the Tomei pump. I was sort of hoping someone had done track work with a name brand Japanese pump. I cant think of anyone over this way fitting that description.

Can you help me out with details of the head mods, catch cans etc for the 33?

Cant be 10 bar, surely. 150psi = over 10kg/cm2. On the gauge it reads in line with the table that Tomei provide. Which is in the range of 4 to 6 bar or call it 50 to 85 lbs. But yes a pressure drop (below what may just be possible for the three shims) could be the answer. Who/how did you get yours done?

5W50 Mobil 1 Oil pressure is basically as per the chart. Column to be read is third from the left. If anyone could help with the Japanese on the table that would be really helpfull too. For what it is worth the aftermarket pumps appear to run a couple of bar higher pressure everywhere than an N1.

Needing some help - I am trying to find someone who is running an aftermarket (not a Nismo ro Nissan) oil pump on their RB26 and who runs it regularly on a circuit. Reason being I followed the advice in the forced induction oil control for RB's thread and have an oil puking mess to deal with. The pump I am running is a Tomei one - but anything in that flow/pressure range ie Nitto, HKS , Jun etc etc is much the same. So the question is what other mods or combination of mods dealing with flow & oil/air separation in the head are people running? I have done the tiny 1.1mm restrictor (As an aside does anyone know where to get a really small one from 1mm or less?), the external drain the mines baffles, the Autech can, the Nismo can etc etc etc. Car is fine on the dyno but hopeless on the circuit. Anyway if anyone could help I would be very appreciative.

Sorry I coughed this up. The above post should read RB26. My question remains - has anyone here put an aftermarket (ie not Nissan/Nismo) pump on their RB26 and successfully run it on a circuit? If so what mods did they run with? Here is a pretty picture of some Mobil 1.

Matt, Which Reimax pump was that? My rb25 has a Tomei pump, 1.1m restrictor external drain, mines baffles, baffled sump and it is an oil puking mess. Cant do three laps without the AFMs getting covered in oil. tis fine on the dyno, however. I guess I am asking what peoples experiences with aftermarket pumps is like. Because at this point I am seriously contemplating reverting to an N1.

Actually open ends are a pain because the ends hold a little water which then bleeds orange when you drive the thing next - mostly after you wash the car. So get a closed nut if you are given a choice. Most of them are closed anyway.

Well rubbish weight distribution is a problem for just about every GTR ever built, not just the 33's. You can only try & move stuff rearward really.

Why are you s focussed on he least important of the things on the list of weight redction? The first order of priority is to reduce unsprung weight. So rims, tyres, brake rotors, callipers, suspension arms, anti roll bars, springs, shocks etc etc. Just dont use aluminium wheel nuts because they are shit. The next on the list is rotating/reciprocating parts. Eg alloy cam gears instead of stockies, pulleys (material and ratios), flywheels, tail shafts etc etc. Only then do you get to the dead weight. The first and easiest thing is the battery. Dry cell it & you have 10kg. Then do all the other bollocks on the lists. Easiest thing to do if piss off all the bracketry in the car & cable tie everything. Oh and the stock front bumpers weigh a tonne too.

Look if it is just one side the way we do it in the bush is to swap the top plates over. If the knock follows the plate then you have a winner. If it doesnt it is in the shock.

Fatz if it helps I can dig out the dimensions for the GTR stuff. From memory the Nismo GTR castor rod is basically as per stock just a few (4 or 5) mm shorter and a stiffer rubber. As for the upper arm not sure it is any different in the steel to a sotcker - just harder bushes.

It promotes fake plastic racing for what is now a fake plastic formula. Dump the thing before it kills someone.

What makes you laugh. It just shows how unscrupulous Ferrari are in going about their business. It is not sport, hasnt been for a long time.

C'mon Roy you will. You will be the same as me. Sitting on the lounge watching the race muttering crash you fkn fkr over and over again.

I take a different view. A 60D I wouldnt bother with - a 7D I would. The 7D has alot of good features it is not just about sensor size. Yet to see what the 5D mk 3 has to offer. If you are not in a rush maybe wait for that & if it is not what you are after the 5D Mk 2's will be cheaper by then. A 5d is a balls achingly good camera for the money.

Bollocks to the Renault Lotus stuff. May as well go old school. Go to the merch section and, um, merch it up. http://www.classicteamlotus.co.uk/content/shop.aspx Or here: http://www.grandprixlegends.com/motorsport-and-f1-merchandise/autosport/retro-gp-t-Shirts

Is it a dog in dirty air or do they run alot of down force with a (relatively) down on power motor (compare it to the MB brigades trap speeds)? Seeing the Red Bulls over take anything always looks like hard work. They are quick over a lap (maybe due to the downforce) but struggle to overtake. So is it a downforce/drag thing or are you saying the car is inherently shit in and around others? But either way you are right the effect of that is to make Webber look worse than he may otherwise.

No it is like saying your Nissan has, for example, brakes made by Sumitomo, an interccoler from Calsonic, turbos by Garret and so on. Subcontracting is the norm and is to be expected. What would it stop at some arbitrary level? Anyway all this is wholely off topic. Best leave the people actually involved to resolve it as best they can and as they see fit.

It is not a reasonable assumption. Given the metallurgy involved in the turbine wheels especially it is far more likely they would sub contract the work. How do they keep QA under control - oh I dunno, maybe ISO 9001 has something to do with it. What are you saying you dont have your own laterite nickel deposit?????????

Here, in fact. p19_p20.pdf

Its funny you say that about formula libre & hillclimbs. Over here the most recent trend is to stop open wheelers from competing in hillclimbs (on safety grounds) and now open topped cars (same grounds). Our series had to bin a round at Meelup (best hillclimb venue we have) because of a ban on both those types of cars. "Permanent" hillclimb tracks ar ok for some reason - even wheen they are more dangerous that the ones one closed public roads. So, yeah turn up in a 800hp GTr and you are fine. A 100hp MX5 & you are unsafe. Madness.
