  1. For new BA’s in 2003 I would have said we had 170 to 205 rwkw, manuals reading higher, based on our dyno days. DD dynos used Shoot6 in those days, before shoot6f existed. At those power levels there is around 1-2% difference between hub dyno using DIN correction and dd shoot6. If you use SAE on a hub dyno it will read a lot higher (Tunehouse use DIN). MRT have used SAE in the past. Brian
  2. In a 4 litre turbo you'd have a major problem if you were using boost on cruise at 110kph. On a 1.3 litre OK, but not a big torquey motor like the Ford has. Higher revs will use more fuel at a given speed than lower revs, dependent on load. e.g if you were revving at 2500rpm under minimal load, at a given speed, then changed to a different diff, and had 2800rpm, again under minimal load, I'd expect to use more fuel at 2800. Since the BA the overall drive ratio in tallest gear has got progressively lower (taller). Not sure about FG manual ratios; I think the 6th gear has a very tall 0.55, but not sure about the diff ratio. I've had the T5 & 3 different T56 boxes with 3 different ratio diffs. The taller overall drive ratios make a huge difference to cruise fuel economy. Brian
  3. 6 speed manual is different. The T56 box has a 0.62 6th gear ratio. The BF diff has 3.73 ratio. At 110kph you will be doing around 2100 rpm in 6th gear. By comparison with a BF 6-speed ZF The ZF box has a 0.69 6th gear ratio. The BF diff has 2.73 ratio. At 110kph you will be doing around 1700 rpm in 6th gear. Brian
  4. The T5 box has a 0.73 5th gear ratio. The BA diff has 3.46 ratio. At 110kph you will be doing around 2300 rpm in 5th gear. You would need to drop in a 4.10 diff to get around 2800rpm. There are a number BA's that had this done. Brian
  5. It's not a fast circuit, fairly tight, but good for testing your car, and fairly car friendly. It'd recommend you do some youtube searches, plenty of incar videos to check out the track and get to know the corners. The fishhook half way around the track is where most people come off, so take it easy through there until you get the hang of it. Be careful breaking at the end of the main straight; if you miss the turn there is a bit of a drop off from the bitumen if you go off. Brian
  6. Stock, GTR is definitely not in the same league, price range or target market. Standard, Veyron top speed is around 130kph higher, which is a huge margin. Veyron power is significantly higher. It is just an incredible car. To get the GTR closer to the Veyron over the 1/4 mile you need an AMS Aplha 9 kit (10.1 & 138mph on pump fuel). ref http://alphagtr.com/alpha/models/alpha-9-package/ Brian
  7. Great result, strong engine, and you probably do make more power because of wheelspin powerloss not being recorded or estimated. See if you can get a correlation between engine rpm and roller rpm. I have seen some big differences. Brian
  8. Thanks. These look like a good compromise option, rather than having different sized wheels front and rear, so you can at least rotate the wheels, and get a bit more life out of the tyres. Good 265 rubber should work for most, and 265/18-35 is very close to the originally rolling diameter. 265 fits OK, as it meets the minimum recommended rim width of 9". I have these wheels on my Sti in 18"*8", good price, and they were surprisingly light, and spoke design should clear calipers OK. Brian
  9. Here's an old picture of mine when it twisted. It did not break. That was after about 50 passes and around 400rwkw, and only happened when I stalled it up too long. I don't know if Ford understands what abuse means, but stock torque should not cause such a break that you have. I'd say that it is clearly a defect, and could have had dangerous consequences if it happened when you were doing something like overtaking. I would have expected any safety conscious company to examine such a defect. For a non-expert to dismiss such a case to avoid paying is missing the point. I would expect any out of warranty issue to be addressed seriously. The fact that you have been a loyal and excellent customer should warrant extra attention, and you would get better attention dealing with people at a higher level of responsibility, where a more appropriate business commonsense decision can be made. Good luck. (Time to get a GTR) Brian
  10. That's just so bad. I've seen photos of twisted driveshafts (including mine) after too much dragstrip spoolup, but that is something different. Looks like a fairly clean break rather than a twist and snap. Brian
  11. Good if you want street legal. I ran a 138mph pass on these tyres, so possibly the highest mph on full street legal tyres. I you feel the rubber on these you find that they are nowhere near as soft as MT's. Most people use MT's for a quicker 60'. Brian
  12. 2011 model R35 GTR 0-100 in 3.0secs in stock trim. Incredible launch and good daily driver. Doesn't surprise me that it won. Brian
  13. Give Nizpro a call.
  14. Here are the full instructions for the kit. Is that what you have? Brian Fitting_Instructions_XRT300_350.doc
  15. Yes, yes and yes, what more can you say. Thoroughly well deserved. Brian
  16. How does it know which gear you are in? Brian
  17. No way, unless I win lotto, plus my wife would probably leave me, which would cost me more than the mods!. Keeping the car around 400awkw is a very sweet level, and a 10sec package in full street trim. Current exhaust and tune is great; just need 1st and 2nd to be detuned a bit more (as I can currently get all 4 wheels spinning with launch control), and a bit more boost in mid-range. Great daily driver. Check out this video James May tests the Nissan GTR 2012 Launch control - Top Gear. http://www.youtube.com/watch?v=PtrUSa7DexU Once you go over around 450awkw you may start bending rods, and get into engine/trans rebuilds.... usual stuff. Just because they are awd you can still get yourself into trouble with big mods. ref http://www.nagtroc.org/forums/index.php?showtopic=60655 Once you go 1000HP + it would be a struggle to keep grip, and a lot of care would be required. Just mention GTR and the cost of anything is way higher than we pay for xr6 turbo mods. Brian
  18. VW Touareg
  19. Phase IV was going to have 12 injectors, and be run by Unichip. We've moved a long way since 2004! Brian
  20. True, not a direct competitor. many guys trade up from those cars to a GTR. I'm not biased(lol). My future son-in-law suggested I buy the AMG C63. I said no, trust me. After I got the GTR and demonstrated to him the 0-100 in 3.0 seconds launch the smile on his face was priceless, and then he was enlightened. Then again, I'm a turbo addict. If you want something special and stand out you don't buy something based on garden variety cheaper versions. You don't really look at a AMG, rather you hear it, and to most uneducated it will look like just another Merc. I have much the same view of an M3. Brian
  21. Give me a GTR, AWD & turbo any day. 4.2 secs 0-100 is way too slow. 155mph is for pussies. Brian
  22. Just learn to change gears! If you've got a built engine why don't you increase the rev limit. Mine revs to 7400, so it's far more useable. Brian p.s good thread mining; 1st post noted
  23. Rota are good value; I bought some for my STi a few weeks ago. They are light weight; I was surprised. As a guide you should be running 245 on the front, and 275 on the rear. Brian
  24. It's not really like that. It's not speed in the sense of heaps of grunt from say 80kph, because that's about a lot of power or good power to weight. It's the missile like launch capabilty, then add great stabilty, traction, fast gear changes, great breaking. It might be a Nissan, but it still turns heads. Brian
  25. 384awkw with just 15lb boost. Because it has traction it smashes my ZF F6 that has around 480rwkw, and I would think any Ford turbo. 0-100kph is brutal with launch control (3.0 secs flat, and I believe it), but with tyres that are not hot you can get all 4 wheels spinning. There is a huge amount of go-fast bits and pieces for the GTR, more than is available for the Ford, and it responds well to mods. AMS and others have heaps of parts, but it is all very expensive. Car can be tuned for boost-by-gear tuning, and the lack of this is one of my major criticisms of Ford tuning capability. Of course 100kph+ it isn't as fast as my other cars; my STi leaves it for dead with around the same power at 4 wheels and 450kg less weight. Add E85 to the GTR and it will do 130+ passes with ease; E85+billet turbo 135+, and that it is probably at the limit of the stock motor. Awesome car, and very easy to drive around town, and I drive the DSG in manual mode. With the new tune it makes about 12lb boost by 2500rpm, so it is incredibly more responsive, and you can use the power with far more confidence than in the Ford, where wheelspin is a major issue.
