  1. The Z Design Studio links graph maker isn't working for me. it'll load all the boxes right, but not the graph. Do you have any other links to graphical layout calculators? the other linkes are either bad/gone or text output. I'm trying to see what the Borg Warner M76 (0507) box from the Aussie XE Falcon will give me when matched between a 3.7 R200 diff and a Rover V8 with 7500 rev limit, driving tyres sized 225/60R15.
  2. Holy Crap Batman, Someones gone and painted the Batmobile PURPLE!
  3. Faster? you call 32.1Kbps at 45% utilisation fast? press ctrl/alt/del and click the network tab, whats yours?
  4. Starting at the bottom builds character, and usually calluses and muscles too I don't mind getting covered in oil, grease, blood, dust or a number of other things, Animal ♥♥♥♥ is nasty, but had that on me before too been there done that over the years, living on a farm is a pretty messy occupation.
  5. Well one would HOPE you used clean paper!
  6. get a couple of hydraulic rams and fit the ramps to the back of the truck like a tail-lift truck just hit a leaver and then drive off
  7. why not just pick up an old flatdeck truck with rear ramps. ebay shows a number of ex-salvage tilt deck single vehicle trucks. and you could rent it out to a car club for a bit of cash too
  8. easy throught to connect with the posts in the order they are, but no, i was using plenum as in the meaning of an open chamber connected to pipes, "expansion chamber" or "collectoin chamber" would also have worked, but the word plenum was right there. I saw you were talking about intake plenums but I just went off on a tangent about exhaust pipes with 8 equal length tubes to a central chamber. Your 180* header post did spark hat thought tho I was wondering why the spaghetti snarl of 180* header pipes when a central chamber and 8 simple, basic, easy plumbing lengths to a central collector wasn't used instead. BRAAPs explanation of taking a torque drop right along the entire curve explained it as far as standard engine design goes, where power and torque are the goals and the exhaust note is a byproduct. The next question is the tradeoff loss of torque acceptable when power/torque is NOT the goal beyind having a drivable engine, but the exhaust note IS the Primary goal of the exercise... assume torque is halved, looking at the first engine sales page in my copy of petrolhead, chevy small block 350ci, 355Hp, 404ft/lb, so say that drops to 200ft/lb. In a Z, 200ft/lb is still respectable performance and quite a drivable engine for something with a nice exhaust note.
  9. and VLSDs are not even covered, he mentions Open diffs are the easiest to drive, and a VLSD is effectively an open until a wheel slips and starts spinning at a high rotational difference to the other, much greater than just going round a corner. so how does a viscous diff stack up as far as drivability vs performance compared to the helical and Clucth types
  10. 8-1 describes it, but I was imagining something more like an intake plenum where you have the throttle body and then a chamber, out of which 8 runners go to the ports. Looking at that I wondered why that was never done to the exhaust, 8 pipes from the ports to a chamber, and then 2 pipes out to the rear, so more of an 8 to 1 to 2. A serious loss of torque would explain why however... so much for one more offbeat idea the question now is whether the loss ot torque is worth the gain of the exhaust note? would a normal stroke dual plane engine with half the torque be more or less the torque of a single plane engine with half the stroke?
  11. While 180* headers are mentioned I've never seen a plenum header, equal length pipes running to a central plenum which then has the main exhaust pipes to the rear. Surely if the burbling sound is caused by mismatched banks firing, then running the exhaust pipes to a central plenum where everything can equalise before heading out down the exhaust tubes to the rear would clear up some of the noise? and do the job of a X cross? What would happen to the engine note if you dry sump and put a plenum under the engine with equal exhaust header pipes from the ports to it?

    no, it's a case of leaverage, looking at it, the arm was low, but hit the bridge below the side fence, you stick something into a 90* corner while running past and the leaverage means it will stick in the corner. In this case the body of the excavator has a hell of a lot of inertia and caused the arm to punch in, and since the arm stowed would form a trangle side and friction/drag pulled it up, that punched it up through the road base, you can see where the bucket slammed into the underside and rebounded in the next picture. An interesting illustration of leverage and inertia Ps: as to the strength of the material making up a excavator arm, they're typically a buttressed "I" section with side plates covering the open sides of the "I" beam. The 17 ton Samsung the local contractors had was made from Bisalloy plating between 26mm and 15mm. this is the same plating as is used on gun ranges as steel targets in 10 and 12mm thicknesses. The photo resizing screwed up and pixellated the engine bay door writing in the pic, but it look like it might be saying 220, which would make that a 22 tonner. so if it has thick plating making up the arm, of thicknesses 2 to 3 times the thickness of something which will survive years of being smashed with bullets, then I'm not surprised it bashed the bridge up
  13. twin turbo V10 viper lump in a street registered Lotus 7 replica?
  14. F-4's could take off with their wings folded but for some reason the navy brass didn't like it Took a longer takeoff roll from a land airstrip, but it has been done and documented
  15. it peaked at 2.28 NZD a litre some time back but has dropped back lately. so it's about 40c a litre cheaper than it has been at one point in the past year. but the current price has held stable for a while.
  16. $1.83 NZD a litre for 91 octane regular. A us Gal - 3.75L, so $6.8625 a gal running 6.86 though xe.com gives 4.04290 USD so I paid 4.04 a gal last time I topped up the 4x4 95 octane is another 5c/lt, and 98 is another 12c/lt above base 91 prices at most places.
  17. You ain't had much dealings with sales have you? that's the base method of communication in sales, making someone answer a question makes them think about the answer... tell them something and it's in one ear and falls out the other
  18. happens every other page today... somethings screwed in the servers
  19. Serach on here is your friend. IIRC the S13/14 uses the FS5W71C while the 260Z has the FS5W71B which is the same 5 spd internals in the older casing, do a search on here, I think you can unbolt the front of the S14 and 260z gearboxs and switch them over. so you have the L series front body and bellhousing on the silvias internals and tailend. Search on here and you'll find TRUCKLOADS of information on the different gearboxes and swaps.
  20. Used exactly the same stuff as FG, West System 105 resin and 209 extra slow 40min hardener catalyst. not surprising as I was making a motorcycle front wheel mudguard out of FG interlaced with CF. broke the front mudguard so I glued it together with plastic cement, covered it in a couple of sheets of gladwrap/saranwrap/plastiwrap sitcking and moulded a plaster of paris mould around it. the two sheets meant the PoP came off the part easy and I had a casting mould. layered FG matting cut into 2"x10" strips interwoven with 1"x6" strips of CF so the CF was interleaved between the FG and each bit of CF touched several other bits of CF. I then used bungee cord to hold the two plaster of paris moulds together while it cured, and finally soaked off the PoP and scraped off the gladwrap, trimmed and sanded my new CF reinforced FG mudguard. works fine for single one off pieces when perfection isn't required.
  21. Depends on if you want the LOOK of CF or just the strength, I just wanted a layer of CF to help stiffen a FG part I made, as CF is structurally stronger. If you paint it you can have a shitty mould and bog the hell out of it without problems, but if you want it to drape well and look seamless and pretty with a clear resin exposing the CF weave, theres no chance of bogging in hollows and sanding down humps will likewise ruin the look.
  22. http://www.solarcomposites.com/composites/compositecarbon.html oops, just noticed you're in aussie not the US, Last lot of carbon I bought was a single sheet of offcut from a boatmaker to clad a fiberglass bit I made. try looking through the phone book for boatmakers. especially racing boat and rowing skiff makers.
  23. The Spitfire was Aluminium not wood, the Mozzie was all wood, and damn fast n nimble too, but neither the Spit or the Hurricane used wood for anything structural.
  24. given the way it curves and swoops, the builder must be a violin maker
  25. the ford sierra is always popular in the UK and commonwealth.
