Couple roughies in the top ten for qualifying. Perkins appears to be in world of pain. As does Garry Rogers. http://www.natsoft.com.au/cgi-bin/results....10/2008.MOUN.Q5

Ah, ok. Cheers. Sounds like a job for Captain Cable Tie.

V8 Supercar driver Paul Weel is expected to be cleared of any serious injury following a heavy accident during practice at the Bathurst 1000. V8 Supercar driver Paul Weel is expected to be cleared of any serious injury following a heavy accident during practice at the Bathurst 1000 Friday. Weel, 29, had to be extracted from his PWR Holden after a collision with Team Kiwi Racing driver Chris Pither. Pither walked away, while Weel is experiencing some lower back pain and has been airlifted to Nepean Hospital as a precaution. Pither and Weel will take no further part in the weekend though, with both cars suffering extreme damage. The accident occurred near the McPhillamy Park area of the circuit, when Weel made contact with a safety barrier and slid sideways onto the track and Pither slammed into the driver's side door.

Hope so. I will do a compare & contrast for you over the weekend.

Not yet mate. Usually takes 2 full weeks for stuff to arrive. WA being so remote & all. So at best today, probably next week. Forgot to ask you about hoses. Are the threads etc same as for ordinary Skyline Brembos? Pharken Japanese holidays means I didn't get my usual email from *insert random name of Japanese parts supplier here* telling me the rims are a further 2 weeks delayed. So I will have plenty of time to bling up the callipers.

I bought: Nissan Brake Master Cylinder R32 GTR (46010-05U02): 36,100 yen Shipping: 3,700 yen (to WA probably cheaper to over east) From Greenline. I didn't think it was that cheap but it got sent quickly, to my door & in retrospect: BARGAIN.

Hmm Davo P5 in #18 with a 2.07.6667 but Owen P4 in #17 with a 2.07.6607. So why did djr chuck so much money at Courtney to come on board? Skaife in P13. What happened to his mojo? http://www.natsoft.com.au/cgi-bin/results....0/2008.MOUN.P10

I went through this on my GT-R. Best advice is check the front diff before you do anything else. Second thing to keep in ming is that the ATTESSA clutch pack has an end piece/shim. These vary in thickness & you need the right thickness to ensure the system works properly. Nissan Australia DO NOT carry stock of this part. So your car will sit in a workshop for weeks.....

Maybe - they are short odds for a podium. I just don't think they will have that last little bit of speed near the end. Here is hoping Junior doesn't stick it in the wall this year (again). Would be a popular result if they did manage it, however. It would certainly make me smile. Garf fastest this morning with a 2.06.99. Murph is up there too, so good on him. #18 P5 & Wargbanna is doing a bang up job.

This may be helpfull. Should be easy enought o nut out. Temps were from a turbo rotor with an unshielded airbod. What you are seeing is pretty normal. Results from dry road testing on the weekend. Conditions: Ambient 15 deg. Drive down hwy at 100 k's, brake and accelerate from 2nd gear throught to 8000 rpm in 4th, cruise for about 30 sec and the accelerate from 3rd gear to 8000 rpm in 4th. Stop and idle for about 45 seconds shortly after. Temps at 8000 rpm in 4th for first test: air filter 48 after turbo 117 after I/C 45 throttle body 51 Temps at 8000 rpm in 4th for second test: air filter 47.3 after turbo 122.6 after I/C 45.9 throttle body 53 Temp at air filter after stationary at idle for about 45sec was 84 deg! Thermo fans switched on and filling engine bay with hot air obviously.

Sorry I may not have explained myself well enough. You can easilly derive acceleration data (ie lateral & longitudinal) from GPS position data. What I was trying to say was that presented graphically it is more useful when plotted against distance than against time. It makes it easier to see what was happenning at a certain point on the track rather than a certain time into the lap. Hope that makes sense. Straightforward accelerometers don't do distances well because they get messed up by hills & gradients etc.

Tachos aren't accurate. Mine over reads by a few hundred rpm.

P3 times now up. 888 quickest with a 2:07.5975. Then Murph, FPR, PRick etc. http://www.natsoft.com.au/cgi-bin/results....10/2008.MOUN.P7

From what I have tried I have found that GPS based position information if much better than the accelerometer based data simply because it allows you to plot your speed trace versus distance which is much more usefull than having it versus time. It highlights the small gains you end up looking for.

R32 GTR's do 28.5 km/h per 1000rpm in fourth.

Thats what sh!ts me. GTR's have TPS, steering wheel angle, front torque %, RPM, wheel speed all there for the taking. But without spending large amounts of cash you can't log them.

Not seen that before. Rpm traces tell you alot as do TPS & others. Shame no one makes it easy to tap into the few extra inputs that can add so much useful info. Anyway the performance box is <$1000 but so is the Starlane gear too. The Starlane stuff appears to have more functionality for the dollars.

Can't see a VE winning much. Too much aero drag will kill them down Conrod. Put the house on 888. Or FPR.

Yeah saw that. You will notice some idiot called djr81 posted in it. Check Pauls thread about his data logger for its specs.

Link to a relatively new release. It has some handy features - mostly the bad lap/good lap/best lap idiot light which may be useful for qualifying, sprints etc. http://www.starlane.com/en_news.htm For what little it is worth, IMHO the most useful parameters for a data logger to analyse driver behaviour are: GPS coords, ie lat & long but also heading if available. This allows you to work out accelerations but needs atleast 10Hz logging rate to work well. RPM. Throttle % (easy to get out of a GTR as it feeds the ATTESSA system) Steering wheel angle (Again already used on GT-Rs) Torque split. This lot will tell you a great deal about car behaviour & enough about what the driver is doing to affect it. Having some functionality in the logger unit itself to assess the current lap you are on can be a great help too. Mostly this involves sector splits & tracking whether the lap you are on is ahead and/or behind & by how much. Good software is also critical. Best of luck with it. Your ATTESSA controller is a nice bit of kit & works well.

Nope. Just the part number stanped onto t he end.

They aren't anything special. Just Project Mu sized for a 33 R. The fronts only weigh 0.5 kg heavier for the pair than the rears. But you can't get any hatted back rotors for sensible money. Also the vanes on the rear are, for whatever reason, more substantial & numerous than for the fronts. No idea why that is but I stopped asking such questions after I got sick of the local stuff cracking.

Mine turned up the other week too. Has BM57 cast into the side & externally looks identical to the R32 unit.

Actually it is, sort of. As I understand it you are obliged to do what you can to avoid an accident.

Been looking for a new logger which which records both GPS based accelerations etc & rpm. This thing appears to do both for a reasonable price. Anyone heard of them or used them? http://www.starlane.com/en_Athon_GPS_multi...onal_chrono.htm
