Tricky-Ricky Posted September 17, 2006 Share Posted September 17, 2006 14.1:shock: Your brave! think i would be a bit hesitant about running 12.1 without a failsafe, i still need to hook up a relay and something to cut boost or interface with the EMU before i would attempt anything more than the high 11s. LOL just noticed this "lucky AFR 13 lean'n'mean" lucky yeah;) Link to comment Share on other sites More sharing options...
paul mac Posted September 17, 2006 Share Posted September 17, 2006 out of interest does methanol mix readily with water and is it safe to use with plastic tanks and pipe work Link to comment Share on other sites More sharing options...
JohnA Posted September 17, 2006 Share Posted September 17, 2006 out of interest does methanol mix readily with water yes. if you have a 50% mix then it isn't even flammable. It then reduces the surface tension of the water, making it much easier to evaporate when in mist form ...is it safe to use with plastic tanks and pipe work It depends on the plastic, many are OK to use with alcohols. What you do not want is high concentrations of methanol sitting for long periods in parts not rated for alcohols. You may get some furring in aluminum parts for example (after prolonged contact, days+) Link to comment Share on other sites More sharing options...

JohnA Posted September 17, 2006 Share Posted September 17, 2006 At some point I should re-write the WI pages of my site. They are kinda stale and obsolete in places. There is nowhere concentrated info on the subject, so it is probably worth spending the time to do a decent writeup. Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted September 18, 2006 Share Posted September 18, 2006 Hi dick did you mange to find that post about jet size and mixture rate's?. thanks Found the chart, but can't remember or find the calculation yet. http://www.imagestation.com/picture/sraid215/pd412cc22545ed47f6a61f4bc7b65262e/eceb69be.jpg Link to comment Share on other sites More sharing options...

JohnA Posted September 18, 2006 Share Posted September 18, 2006 I would only use this chart as a rough starting point. It is better to keep your engine running (for the full voltage to the pump) and disconnect one lug from the pressure switch. This will activate the pump, and if you have your nozzle(s) sitting temporarily in a calibrated container you will see more accurately the real flow per minute. It is not 100% accurate since there is no boost pressure (or vacuum ) for the pump to work against, but it takes into consideration the real path (sucking from the tank, pushing through corners etc) Link to comment Share on other sites More sharing options...
