Scrap the Franken?? FINALLY RUNNING PERFECT! :)

[rabbitman]

My stock (fast glow) system does after glow for 5-10 seconds, I have a ford starter solenoid powered by the stock relay so it's easy to hear when the glow go on and off.

Aren't smokey, belching exhaust pipes on our cars our badge of honor?

I find it very useful to get a white van driver to stop following so damn close by giving him a soot sandwich - a few seconds off boost full throttle 

but the clattering and white smoke is not so cool.

i would try upping the break pressure.. finer atomized fuel burns easier.

I should have 155s in - how far do I go?

At the risk of annoying more conventionalists, the clatter is not neccessarily from inefficient burning but from a combination of rate of combustion, and timing of that combustion, so experimentally, why not try lowering a set of injectors to say 140 or 130bar.
Keep timing the same for effective slight advancement, of initial burn but a stretching out of the whole burn. Even CAD-man dwelt upon the idea

Aren't smokey, belching exhaust pipes on our cars our badge of honor?  Mine no smoke unless I retard it a bunch.  Then it is gag city.  But I can't take the smell that thick so I make it run like he would like he wishes his would.

if i lose boost, my car pours a straight stream of charcoal out the pipe.. and has about the power of a n/a..

normally tho, i get ONE PUFF of smoke on start up if its SUPER DUPER cold outside. and it stumbles and chokes for a second, so i burn the plugs for about 10-15 seconds till i can feel the motor smooth out and pop evenly on all 4 cylinders..

"Keep timing the same for effective slight advancement, of initial burn but a stretching out of the whole burn. Even CAD-man dwelt upon the idea" Mark UK

I think this might be the ticket for a lot of us.  As age and wear change the initial design criteria of our engines we modify.  Hagar advocated running lower pressure injectors to make it smooth but he also was looking for mileage.  Wasn't his theory that one would lose energy of the upstroke if you had it advanced too much?  Thus the clack and bang or marbles on the plate sound.  The longer burn came from the more solid stream of fuel injected at the lower pressure.  Thus less clank and bang. 

Love that CAD-man title, He may have stayed longer or left earlier if you used it sooner. LOL.

I think Hagar initially advocated 155bar, as he kept referring to using the 193's in his TD and setting pressure to maximum stated in the Bentley.
Lower pressures more suceptible to poor spraying etc, but I think Hagar, CAD-man and myself came to the conclusion that there may likely be economy benefits to good condition injectors running lower pressures.

I am running old French 293's set to about 130 bar, and retarded to about 0.7mm.  The slight advance idea for Reg, was because of his hybrid issue.

My only attempt at a new matched set of nozzles [old stock 193's ] was thwarted when I broke one, and one was duff, and that left me with 2. So back to the closely adjusted ones previously mentiioned.

Mileage 50[imp] round town and nearly 60 interstate.[motorway].

Close match injectors with pieces of tape measure spring and razor blade

Had to laugh at that, Super Duper cold doesn't happen down there . Right now nights get to about 20-25F and in the morning I have to crank it a half second longer and it fires off with slightly less boom.......I'll try to remember to check the tailpipe next time.

we had some single digit, and low double digit temps a couple years back.. thats COLD to me..

[regcheeseman]

I've got 135 bar injectors in at the moment, will try a bit more advance and a glow plug mdification.

[vanbcguy]

For what it's worth, the Mk III cars (where the AAZ was originally found) keep the glows on for a WHILE after startup.  If I fire up Jezzie I can usually idle in the driveway for 20-30 seconds, pull out and drive about 8 blocks before I hear the relay click off.  I think it's about 2-3 minutes of afterglow.  The glowplugs don't seem to mind, the biggest thing you have to worry about is your alt belt!!

She does that much afterglow even when it's fairly warm out (+10C)... Maybe worth throwing a switch on the plugs to see if it helps?

[regcheeseman]

AT LAST!

It's fully sorted! Now moke white smoke on start up, idles perfect when stone cold, nice and quiet, running on near standard timing.

Could believe that the solution was so simple...



Simply remove the 1.6 block and fit a 1.9 block in it's place - all the original franken parts can stay.

[8v-of-fury]

So how does the full AAZ feel??

[Mark(The Miser)UK]

Just in time for all that black ice
Reg, about how many times have you whipped engines in and out? Man-hours?
I bet if you decide to sell you will be able to say "I put in 10 G's worth  of work into this" , and noone will believe you. We'll give you a testimonial

[ORCoaster]

So much for the mix and match then.  No longer a Franken then is it?  Just a Frank, that has been dropped. 

[wil892]

Just for reference, the glow plug system used on the GTD engines is different and keeps the glow plugs on for about 30 secs to 1 minute. If find one and put it on these franken engines it might help.
I can tell when the glow plugs turn off on mine because the load on the alternator suddenly drops massively after a little bit.
