Title: RE: wiring tachos with EFI...

I would have them tested at 100% duty cycle.  If you want to test them yourself, just get a stopwatch, a 9V battery and something to catch the fuel into.  Pull the fuel rail from your engine ( with the injectors still attached ) and place one of the injectors above the container to catch the fuel.  Run the fuel pumps and while they are running, place the 9V battery across the terminals of the injector that you want to test.  This will hold the injector open allowing the fuel to flow, effectively testing it at 100% duty cycle.  Time it for 1 minute and then measure the amount of fuel flowed through the injector.  For your malpassi regualtor, I would say the base fuel pressure would be around 45psi @ atmospheric pressure.  Test the other injectors the same way.   Hope this helps   Daniel Kroehn ---- Original Message ----- From: mark krawczuk To: [EMAIL PROTECTED] Sent: Wednesday, April 10, 2002 7:15 AM Subject: injector fllow testing. hi,  does any body know how  , at what ratings they test fuel injectors for  flow rates?   as far as i know they test at 38 psi,  and  at 80 or 85% duty cycle?    once i get some  figures, i might try and build up my own  injector cleaner,flow  rating bench.   also ,  has any body heard anything  about ultrasonic  cleaning of injectors  vs   solvent  cleaning ? on guy was telling me that he heard of someone  getting this done (ultrasonic) , and  the injector ended up being  worse ?                 mark k --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
