1963 oldsmobile : That's the tractor I heard about. My dad (80 yrs old) told me that itused gasoline when it was cold. When it warmed up, you could switch itto kerosene (cheaper and more available than gasoline). The trouble wasthat kerosene didn't produce as much power as gasoline, so water wasdripped into the carb (which had to be zinc plated to prevent rusting).What I understand about water injection is that water droplets prevent or reduce detonation (knocking) by absorbing some of the heat producedduring compression. After combustion begins, the droplets burst intosteam causing turbulence that causes a more complete burn.Is that all it does? An old car buff told me that it also "cooled the burn". Huh? I'd like to know more about it. tvoivozhd>>>injection was pretty simple---small orifice, small flow under alot of pressure to vaporize it. Either alcohol or ethylene glycol could bemixed to avoid freezingat above 30,000.tvoivozhd>>>my spelling error, as I recall, it was Advance-Rumely. I used onein 1930's to run a threshing-machine---rye, wheat, barley and oats.On Thu, 25 Dec 1997 02:06:25 -0500, "James Adrian van Wyk, PE, PP" wrote:Chevy lowered the turbocharged Corvair's compression ratio from about9 to about 8, used a pressure sensitive control to retard the ignitiontiming, but no>> factory<< water injection. It used a specialmuffler and carefully sized turbo to avoid using a "wastegate" tolimit boost.
1963 oldsmobile : There were aftermarket makers of water injection for Corvairs, andother turbocharged cars. It was suggested to allow higher boost orcompression ratio, not for more power by itself.Turbocharged Corvairs were made from '63 to '66. Folks that "hoppedup" these engines claimed that the actual compression ratio wasusually even less than stated in the brochure. Probably to avoiddiscouraging customers who make decisions based on "specifications."In the early 70's this was listed as the largest automotive use ofturbochargers in history. About 60,000 were made. I'm pretty sure Turbo Saabs and Volvos exceed those numbers easily.Around 1963 Oldsmobile turbocharged a small aluminum (215 CID) V-8,and left the compression ratio fairly high. It used a wastegate, andTurbo Rocket Fluid injection. Olds realized pretty quick that abigger engine worked as well for less money and complexity, andcompact cars swelled up to accomodate larger engines.<<snipped bulk of discussion surmizing what water-injection does>>Ever watch tractor-pulls?? Many of these guys are running 3500+HPdieselengines, and _most_ of those use water-injection systems. It seems tobealive and well in that "hobby"??

Many of these guys are ;running 3500+HP;diesel;engines, and _most_ of those use water-injection ;systems. It seems to;be;alive and well in that "hobby"??I work on diesel tugs in St. Paul. We have an old tug with engines dating backto the 60's that had an injection system fitted to it a couple of years ago. The injection is 50/50 water/alcohol and raises the rpms by about 50 when theengine is under load. (approx. 1150rpm increased to 1200) The engine is saidto blackstack less-though I haven't noticed any change-and has better fueleconomy in addition to the extra horsepower. HOWEVER...the economics are thus: we are able to get most of out alcohol for free since we also clean out tankbarges, including alcohol barges. When we have to BUY the alcohol managementhas hinted that the system isn't really cost effective.JDWill68
1963 oldsmobile : What is your experience with these.One of the hobby shops near me has someinteresting sounding kits.These are all 'old technology' kits. This means you'll get mediocreengine and interior detail and really poor chassis with few or noseparate suspension parts. Axles are metal rods through the engineblock; typical '60's American car kit practice. Don't let this deteryou from buying and building these! The bodies are quite goodrenditions of subjects you won't normally find anywhere else atanywhere near the price. In fact, if any of these are the 'USAOldies' series or the even older 'flat box series', would you mindposting a list and pricing for us? I may be interested in some ofthem unless they're 'collector priced'.--C.R. Krieger"Ignore 'em, m'dear; they're beneath your dignity." - W.C.

And as I said to my local hobby shop owner, anyone canmake the AM McLaren look good - a real modeller can make a Jo-Han kitlook good..
