| 575133 | 2007-08-02 17:46:00 | 47+ years in the repair/fabrication business of both personal automotives and larger construction and demo machinery teaches a lot to you on an accelerated scale . If you don't glean something in that amount of time, you're either dead or a retard . Unfortunately, I remember a lot . . . sometimes accurately too! Yes . . . alcohol can produce greater power with higher compression ratios . . . but right now since gasoline is still primary, the engines cannot be built to higher than . . say . . . 10:1, and even THAT'S asking for trouble without some NASA-style injection/cooling management . Variable swept-volume engines are currently on the test dynos, but so far they are pretty flimsy and weak and not reliable . We here in the US are getting about 6-8% methanol right now, but there's political intrigue afoot to get that to 20-30% soon . I foresee carburetters as dinosaurs and since they cannot handle such high percentages of non-hydrocarbonous fuels very well, they won't be running much longer . Two, possibly three scenes are playing out . 1) the new car manufacturers are seeking to increase the need to buy new vehicles if the older ones won't run . . . . can you say: "money"? Can you say: "CEO"? 2) the tree-huggers are trying to get everyone out of oil-fueled vehicles for possibly two reasons: a) they really want to clean up the air or b) they are getting kickbacks from the electric companies and the manufacturers too . 3) somebody in high places has a monopoly on the corn crops worldwide . Sidebar: There are places in Mexico that haven't seen corn for tortillas on the store shelves for almost a year now . . . and they are plowing under their Agave crops (tequilla ingredient) and planting corn on almost all the arable fields in South America . The yields are all pre-sold . Corn is the primary staple in South America . . . maybe they should learn to eat cake . You can't trust individual people with hydrogen fuel . . it's too dangerous and the craters where the explosions happen will tax the road repair crews too much . Nuclear power is just out on so many levels . . . if the average driver can't be trusted with hydrogen, can you imagine the peripheral damage from a car going "China Syndrome"? All the proponents of electric energy for personal transportation are just silly . Where do there bubble heads think the electricity comes from . . . organic crickets? |

| 575137 | 2007-08-03 00:04:00 | no ethanol is a strong solvent, and will dissolve/degrade many plastics and most rubbers . it also has been found to dissolve deposits in fuel lines/tanks, breaking off bigger bits that then block injectors/jets further down the track . as such it isn't recommended for older cars that weren't built to run ethanol and may have sensitive rubbers/plastics/deposits in them even my '98 and my friend's '03 high-performance dirtbike's manuals both say not to run any mix of ethanol as is will damage the fuel lines and carburetor components . yes meth/eth will eat plastics . it will clean the tanks so it pays to have a fuel filter handy ;) race cars have special fuel lines and carby seals for the methanol . however the point here is . . . . that according to car yards, NZ new 2000 model car is fine with the blend BUT the exact same vechile imported 2nd hand is not ! yeah right . . . . . . i see another tui ad . they all run the same fuel lines and same fuel systems . if its safe for NZ new then its safe for the 2nd hand import . oh and surfer, doesn't pure ethanol have an octane rating of 130 or something ridiculous like that that allows for much higher compression, giving better efficiency and more power - albeit at the cost of very high fuel consumption yes/no race cars run on higher octane race fuel anyway so the difference in compession used is mininml . the big difference is methanol (ethanol is not much different) is a poorer fuel power wise so you need to use a lot more of it to get the same amouint of power . the big advandage is methanol burns cooler and the larger amount of fuel helps cool the motor . downside is its trickier to tune and isn't as constant as petrol . no doubt partly due it absorbing water and the heat to evaporate it . mind you it has a lot nicer flames out the exhaust :cool: |

All the proponents of electric energy for personal transportation are just silly. Where do there bubble heads think the electricity comes from...organic crickets? no, meant nuclear power to generate electricity for electric vehicles - in NZ we use mostly wind/hydro/geothermal with a bit of coal too, so for us it works out cleaner to run EVs and has the added bonus of not pushing the price of food up **** i don't trust NZ motorists with petrol, let alone nuclear reactors:rolleyes: |

| 575141 | 2007-08-03 06:30:00 | It is all very puzzling indeed. Those from the UK of a certain age who were around and drove in the 50s and 60s will remember Cleveland Discol. This had 10% ethanol (or ethyl alcohol), and came in two flavours, Premium grade and Super grade. The Super was 100 octane, and boy, did it perform well in a souped up Lightning-ised Black Shadow. The name 'Discol' came from Distillers Company Limited Best results were obtained from fitting bigger main jets in the Amal carbs, I ran 9:1 compression ratio and #400 main jets. The point is that this fuel was used by all and sundry, in all types of cars, many still pre-war as well as new ones. There were never any problems reported with fuel lines or seals etc, so what has happened since? Materials are supposed to be so much better these days, or are they? It was discontinued sometime during the 1960s. Cleveland was a division of Esso. www.imagef1.net.nz |
