Re: still funny under boost....cuts out intermittently.

[mark krawczuk]

hi, i`m using some mercedes injectors, not sure what they flow....... am running boost retard canister. i have fitted a malpassi reg, and it still ran the same, i then  closed plug gap up it was 98 percent better. i hit boost about 5 times. no worries...         THEN   it was idiling funny,put my foot on the pedal, and it dies down,    cant get no revs, i pulled the vac line going to the  digi one, then after a quick stabon the pedal, i could get it to rev pretty well, and actually drive it,   maybe the  reg settled down , and needs the fuel pressure  reseset?, i`m getting a pressure gauge tomorrow, and check it out then.  ----- Original Message ----- From: steven.taylor To: [EMAIL PROTECTED] Sent: Saturday, March 16, 2002 3:43 AM Subject: Re: still funny under boost....cuts out intermittently. Mark, Are you still using the factory injectors???? I remember u asking about injectors.... If so id say that is your problem. My injectors wouldnt flow much more than that. With the malpassi reg, ca18 inject, and good fuel pumps i was able to run 22psi+ easy. As for the ignition i  ran a S2 dizzy - which i think your running??? Have you fitted a boost retard unit and sorted it all in that regard?? If so then run some BPR7ES plugs (or 6ES's) gap them down to around 0.6mm and youll be right!!!!!!!!!!!!!!! Then boost up 10psi is ordinary you want to at least double that.... Steve.

Sounds like it's running out of something - if it feels like fuel then it's probably spark TR -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of mark krawczuk Sent: Thursday, 14 March 2002 1:15 PM To: [EMAIL PROTECTED] Subject: Re: still funny under boost....cuts out intermittently. hi,   as it approaches max boost (10 psi max) ,  you will be accelerating, then it would  cut out  for a tick, then accelerate again, then it would , maybe  sorta run a LITTLE  funny for a bit , then accelerate again, . most of the time this happens in the period of about 2-3 seconds, then some times  it might happen fractionally.,  then once in a while it will be okay. i will check into those plugs.       mark k ----- Original Message ----- From: "andrew smith" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, March 14, 2002 10:35 AM Subject: Re: still funny under boost....cuts out intermittently. > Mark, > Usually when the plug gap is to big it starts to miss bad when boosted.What do > you mean by cutting out.How long does it last.Sounds more electrical than > fuel.As far as plug range goes i would probably start with what is recomend > range for a z18t which is probably one range colder than what is recomended for > a L20.You could probably go one range colder again if you run heaps of boost > and/or a hiflow turbo.Use the resistance type that is recomended for a s2 dizzy. > > Andrew Smith > > mark krawczuk wrote: > > > hi,  i just fitted a malpassi efi fuel reg to my turbo l20b/z18 efi set up, > > and it  still sorta cuts out intermittently under  boost. > > > > i have also replaced the return line, from  fuel reg, which at one stage was > > blocked  when i first started to try and get this going, the guy at rpm > > performance replaced a section with  hose , so i replace  the lot with > > bundy tubing. > > > >  i was wondering if it would be worth closing up the plug gap? maybe > > cylinder pressure under boost is blowing spark out?: > > what  plugs do u other turbo owners use? > > > > i have a bb 2 electronic dizzy which  has a boost retard canister and was > > also modified by performance ign services,, and  transformer type coil. > > i have redone all  tappet clearances. > > i have also tried  2 other differnt efi pumps, and the problem is still > > there, so  i`ve gone back to my  origuinal efi pump. > > > >   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/ --------------------------------------------------------------------- --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/ ---------------------------------------------------------------------
