Go right ahead! Just make sure your start from first principles so everyone can enjoy it...
-
Excellent. Go the Williams! Oh, and nice work by Sutil & Davidson.
-
Things you need to consider: How many ho do you want? How many hp will the stock internal engine accept before you start having issues with durability? Re the injectors: Pick some, doesn't matter. I run 700's & it is fine. Sard are good. Re the fuel pump: Nismo make a good one. It is worth replacing he AFM's also. Cams gears as well. There is a thread on Rb26 engines in the forced induction section. Check that & see what others have done & what results they have got.
-
Hopefully it will be somewhat reminiscent of Hill spanking Schumacher in the wet at Suzuka all thsoe years ago. Except with a bit less water. And a different circuit. And Hamilton in place of Hill. And everyone else in place of Schumacher. Yeah, so not the same at all, really.

Unfortunately you don't get to choose. It doesn't make the question invalid, it just needs to be posed differently. Basically all you need to remember is this: If you need to exchange heat or mix gases then the more turbulent the flow the better the mixing/exchange will be (broadly). If you need to transport gas (ie flow it somewhere) the fewer restrictions & smoother the flow path the lower the pumping loss will be. Broadly that is, I don't want to get into arguments about boundary layer effects.
-
Well said Faid. All that is happening is that people have missed recognising that ALL of the flow in the induction system is turbulent. They are confusing a few concepts: 1: Flow restrictions which cause pumping losses which they are characterising as laminar/turbulent flow. Essentially the more changes of direction/diameter/shape etc etc the more pumping losses you will get in your induction system. This is true is turbulent flow as well as laminar flow. 2: Gas mixing & cylinder fill with laminar & turbulent flow. Clearly gas will mix better & exchange heat better the more turbulent it is. Cylinders will typically fill better the less turbulent the flow is. At the end of the day with the diameters of a rtypical induction system, the large airflow invloved & the action of the turbo charger compressor ALL engine flow will be turbulent.

Well Webber must be looking at Rosberg in the Williams & kicking himself. Keke's young bloke has come good this year. McLaren have an interest, but Williams won't budge. It will be more than interesting to see who Ron Dennis picks up if Alonso gets given the arse. If you think about the list of drivers: Massa - Maybe. Think of the Ferrari info he would bring with him. Kimi - Hmmm. Rosberg - Maybe. Wurz - No. Button - Maybe. Rubens - No. Schumacher & Trulli - No. Fisi & Kov - No & no. BMW boys - maybe.... Red Bull - Webber - maybe, Coulthard - no. Spyker, Super Aguri & Torro Rosso - No. Although Davidson occassionally shines. In all, not much choice. You'd have to say, (in no particular order) Rosberg, Massa, Button, Kubica, Heidfeld (Nah, not with Ron) & Webber. He needs experience, a good temperament & of course, speed.

Are You Cracking Dba Rotors?
djr81 replied to Roy's topic in Suspension, braking, tyres and drivetrain
Harden up Roy, & get yourself some single piston callipers with slides. -
Maybe. I just wanted the one that says Nissan, not the one that says GT-R. I didn' think it was colour specific, although the GT-R badge is.
-
To be fair it was more so conjecture than speculation. but my point is that the organisers/Bernie bang on about how wonderful the pit facilities are & the spectator access or whatever. If you are sitting on your arse infront of the tellie on the other side of the world about all you tend to care about is how good the track is & does it promote good racing. No 130R at Mt Fuji.... Perhaps the location will give cause for people to remember the late James Hunt. Anyway, to mark the occassion if Schumacher makes it past the first session in qualifying I will think about buying a Camry or something. There, I have said something positive about Toyota. Well done me.
-
Well the track is rubbish according to everything I have read. Thanks Toyota. Fk it with all the bullshit that has been going on in F1 lately I think my time would be better spent sorting the sock draw.
-
Great. So who wants to sell me one at a reasonable price? I don't want to go near my local Nissan dealers because they are a bunch of %*^@'s.
-
Whether a flow is laminar or turbulent depends on the Reynolds number for the particular circumstance. So maybe start looking for that.
-
The part number for the Nissan badge that goes on the boot of an R32 GT-R. Car is white, if that matters. Oh, and the part number for the biggest tyre lever Nissan sell for when I find the scrote who badged my car..... Thanks in advance.
-
Because I am such a nice bloke I am willing to help. Look at your photos in the first post. Specifically the 8th one showing the back of the rim. If you look closely you will see that the rim has some markings stamped/cast into the back of the hub. Variously the say stuff like made in Japan, show the build date (month & year) & also most critically the wheel size, ie 17*9 JJ +15. The last number is your offset. But please check because the photo wasn't high enough in resolution for me to read it properly. Nice rims, anyway.

Motul Rbf 600 Vs Ap Racing 600 (cp3600)
djr81 replied to Fujiwara's topic in Suspension, braking, tyres and drivetrain
If you want the Motul fluid the best places to go looking are the motorbike shops. For some reason they carry Motul gear. Also it is dot 4 (600) Which means it is much better than the run of the mill dot 4 fluid. The 600 is its boiling point in degrees fahrenheit. Stuff paying $55 for 500ml. Someone will be along in a minute to tell you about the Penzoil gear. -
Motul Rbf 600 Vs Ap Racing 600 (cp3600)
djr81 replied to Fujiwara's topic in Suspension, braking, tyres and drivetrain
Well the Motul is about $25 for 500ml. How much is the AP? -
Actually, check the price of the rotors from Greenline.... http://www.greenline.jp/catalogue/bccatpar...gory=suspension

Are You Cracking Dba Rotors?
djr81 replied to Roy's topic in Suspension, braking, tyres and drivetrain
Here are a couple I prepared earlier. I was not running any ducting & the stone guards were in place. Rotors cracked on the outside. Note the rear failed completely & if you have a look at the front you can see the start of a crack propogating from the small slot. I don't think you need look any further than those slots to see what kills these rotors. Note that there was minimal wear on all of them, pads were RB74's & they got a bit warm as you can tell by the surface of the rotor. I have another dead one at home (a front) that is cracked through from the return slot.....If you have the ear of anyone at DBA tell them to bin the return slots. -
Are You Cracking Dba Rotors?
djr81 replied to Roy's topic in Suspension, braking, tyres and drivetrain
I would be curious to see whther anyone has had their DBA4000 rotor crack from anywhere other than the small slots on the outside of the rotor. -
So what is Alonso going to get at Ferrari that he doesn't have at McLaren. A slower car for one? An even less communicative team mate? A less supportive team environment? Still Ferrari & Alonso probably deserve each other. Can't imagine the departure from McLaren would be particularly tearfull. Massa would want an even bigger paycheque than $40 to go to Toyota. He could kiss goodbye to any chance of him ever winning a GP again.

Yeah sorry, upside down Miss Jane. You need to team a larger rotor with a smaller piston area for the smae brake bias. I fixed the first post. Need to engage the brain before the keyboard.
-
There are three parameters for the brakes (Assuming you have no external balancer). 1. Piston size. The larger the piston area in the calliper the greater the bias toward that end. 2. Rotor diameter. The larger the rotor diameter the greater the bias toward that end. 3. Brake pad friction coefficient. The higher the brake pad friction coefficient the greater the bias toward that end. A new set of brakes SHOULDN'T massively change your stopping distances on a once off basis, unless you are running very sticky tyres that is. What it will do is stop you well time & again. The frustration I get is that very few of the suppliers will quote you piston areas (or clearances for the rims) & all of them assure you their particular setup will be balanced nicely. So they offer you a larger rotor with a unchanged piston area for the fronts & then tell you the balance will be fine. So either it doesn't matter or they are full of shit. I haven't made up my mind on that, but I suspect the latter.....
-
Do what? McLaren didn't cheat. McLaren didn't do anything that all the teams (including Ferrari) routinely do anyway. If it wasn't for the FIA needing to deliver Ferrari a championship to make up for their lack of competitiveness over the past three years, nothing would have come of it. Read the transcript of the proceedings. It would be funny if it wasn't such a sad malodrama. The only people who have done the wrong thing here are Coughlan, Stepney (Who got fkd over by Ferrari in any case), Ferrari as a team (For dragging F1 throught all this sh!t) & the FIA for delivering such an obviously flawed verdict & for conducting the proceedings in such a shambollic fashion.
