    have you ever managed it? we tried sending a little 1hp 4 pole induction motor to the moon but it wouldn't go any faster than about 200hz, i think the rotor iron runs out of ability to conduct(?) the field

    maybe with a higher voltage, its definitely on the to-do list.

    I didn't want to recommend anything actually dangerous.

    It's usually the other bits that fail in my experience.

    The fan comes loose and the motor overheats, the poorly balanced 3rd world cast pulley flys apart or causes the motor feet to crack. The hard drawn ancient copper wire inside the half exposed plastic pipe that's just wrapped around the motor terminals comes loose etc...

    We had a 3hp motor at maybe 160-170hz break apart. Probably it's the larger inertia of the bigger motor that can cause all the runaway damage. Some mad dogs on a course I was on had video of motors disintegrating at 300hz.

    Your probably safe with a decent motor to go pretty fast.

    Drove 2GRFE family wagon from Nelson to Hanmer yesterday, 7.0L/100km is pretty respectable. Now that we have Milly the K11 it doesn't get driven around town at all. 

    Took our 2gr lexus gs350 from New Plymouth to rotorua to auckland loaded up with the kids and holiday shit and got 7.5L /100. And I wasn't mucking around.

    I'm pleased it did that cos it fuckin drinks it in town. :pale:

    I'd check the fuel rail for internal corrosion, if the car has a stock fuel rail which isn't anodised inside and has been run on ethanol it can cause pretty nasty corrosion and a partial blockage. I have seen a single piston meltdown in an evo caused by this.

    I see you mentioned xspurt injectors. They have no filters in them. Could easily get shit in them?

    This is a s4/s5 caliper on a Hilux diff using the 273mm OEM style rotor. It fits a 15" rim with a bit of room to spare.

    This a an rx8 caliper mocked up on the s4/s5 OEM style rotor. As can be seen it won't work due to the shape of the bracket. I have not tried an OEM rx8 rotor as it's large diameter precludes use with a 15" diameter rim in any case. The caliper fits an  OEM style s6 rotor but the combo will not work with a 15" rim either. I've been spending a bit of time in several disc brake rotor data bases looking for options. The s6 rotor might be able to made to work with the rx8 caliper with some diameter reduction but I'd like to avoid having to trim anything unless absolutely necessary. The s6 rotor is OEM 294mm in diameter. I'm guessing something around 285mm dia might work. Fun and games.

    I put you wrong re all of the brake adaptions I sell working with 15" rims. The brackets I sell will allow the smaller types of calipers I cater for (sp20, zre152, u13) to work with 14" rims. That's current but I might have to revise this going forward with any new design packages that will allow use of later (TBA) calipers and stick to 15" rims. The pic above shows the s13 rotor (258mm dia) I typically use for most of the smaller fitments. Sitting on it is a VW golf mk5 caliper. Clearly not going to work for two reasons - rotors too small in diameter and mounting points fouling housing. They are quite deep/tall there aye? There might be a balance with a rotor in the mid 270's - 280's and it still being able to fit with a 15" rim. I might check things out. 

     

     

    I have a hilux diff in a datsun Cedric with s14 calipers and Hyundai sonata v6 rotors. Fits under a 15inch falcon steelie.

    Haven't done anything for ages on it but got a mate to laser cut a bit of 10mm plastic as a bracket and it all fitted nicely.

    The cable comes out pretty straight towards the centre of the diff

  6. 2.5mm hole in the thermostat seems a little small. Thats a lot of time for the hot water to work its way up the outlet pipe to the thermostat, while also getting cooled on the way further delaying the thermostat seeing the real temperature.

    I have crewed on a few methanol race cars and they had a 6mm or larger thermostat bypass,(either around the thermostat, or back to the pump suction to allow some water flow during warmup) with the thermostat as close to the block as possible to enable it to open once it got up to temp.

    Nah it doesn’t move much at all. Remember it’s sourced here not overseas. I’ve been watching it closely last 12-14months price has not moved while petrol is up approx 60%

    It's a product that is stripped out if the raw gas and sold separately as its a higher value product, and helps most plants run better as lpg in the gas processing train is a pain to deal with.

    None of it gets exported, so it's straight supply/demand, and not all gas has the LPS stripped currently

    Curious on the choice behind 8.5:1 Compression ratio for the build but keen to see results :)

    My AE111 Levin project has the 370Z rear brake setup with the Akabono rear calipers (GT4 rear hubs, toyota highlander bearings/driveflange (5x114.3) a hub ring to center the rotor on the drive flange and then an adapter for the brake) went this way as the internal handbrake on the GT4 and 370Z was similar/same size (cant remember if I worked out it could just factory GT4 shoes or if I needed to add some more lining) 

    Pretty sure I brought the bits before I knew that rock auto was the go but I didn't think $330 was bad for rear calipers back then (2019)

    https://www.jegs.com/i/Power-Stop/419/S6182/10002/-1?trk_msg=J0VUDM8LCMF4B3PL9EC2QDMGQO&trk_contact=PHST57KEHEJ4JHTH6OUCNU8TO8&trk_module=tra&trk_sid=63E1DGRI1NVOMSC6D65SIEB518&trk_link=1E1GAD39M374BBES33HDTMRMI8&utm_source=listrak&utm_medium=email&utm_term=Product&utm_campaign=Transactional&utm_content=Order+Confirmation

    Or are you looking at the 370z brembo option?

    I think 8.5 will be a good comp ratio. I only want to run petrol.

    The calipers are all Evo 6-9 brembo. I can get adapters to run the 370z rear disc and the internal handbrake will still work. Plus with the r34 master it will give me a correct front:rear bias without any tomfoolery with a bias valve and whatnot

  9. Yes there is a definite lack of them around now. Its all thanks to the sideways hat brigade and their hectic driving style.

    Gearbox might be OK. Its a late 33 box i converted to push clutch. One of the main reasons for converting to e-throttle is to be able to limit the torque in 3rd gear, and 2nd if required.

    I have a complete transfer case and bearing set to give it a birthday and set up the clutches properly, plus a couple of big boxes to raid for parts should i need it. I have been converting 2wd navara box internals to fit RB for a long time now for a bunch of local drifters and have plenty of parts to keep my box going.

    However, there are a bunch of crazy norweigans who do a conversion kit for the bmw DCT trans. I think it will be about 10k which is a bit much, but dreams are free. Look up HPR tuning, there's some videos of a few 2jz and rb conversions. it looks awesome

    And the old alchoholic barry behind me used to build 3 stage Cng compression/refilling stations that got shipped overseas. Think they are still in use in Argentina/Malaysia etc. 

    Pretty impressive bit of kit to compress it in stages from transport pressure up to 3600psi. 

    Fuck driving round with anywhere near that kinda pressure in ya boot.

    we have some trailers at work for transporting bulk CNG. they are long AF and have 7 cylinders on them. 2 inch wall thickness. 25ton empty, 28 full with all of the psi in them.

    There is a crap ton of LPG there to be used.... just need to tell Methanex they cant have any more and you have decades worth of transport supply.

    Methane only takes gas from the pipe. Mostly CH4.

    LPG is produced by stripping the propane and butane from the raw gas at 4 or 5 production stations before it goes into the pipeline.

    Most of it goes to the port to be sea tankered to the south island.

    Need to increase gas production to have more gas to strip the LPG out. Not all production stations have LPG plants tho. We don't. Yet. If the price was higher, there would be room for maybe 2 more LPG plants.
