Glowtime? Duraterms vs. the old 9G's

Anyone measure the difference between Duraterms and the original 9G glow plugs as far as time to reach max temperature and if they do so with factory glow times?

I simply want to know if the factory glow plug time gives you similar or better heat out of the duraterms the the 9G's this engine/GP controller was designed around.

Do the duraterms go into self limiting temperature or do I need a longer glow time to get this to happen? I ask from both a 1993 stand alone controller and my 1995 burb project where extended glow time has been programmed in.

The glow system checks out down to voltage at each plug and proper resistance of the GP - all new plugs this summer.

This info may help explain why my 1993 starts better if I crank before the WTS light goes out - still suspect IP issue and just need to find time to swap it... (No 6.5 6.2 should start this hard...) I may override the GP's before I break another starter as a shortcut till I have more time... :nonod:
 
duraterms are self limiting. They heat up faster than 60gs but it's been too long since I messed with 9s. But I think it is a replacement plug for all 6.2/6.5s
 
60G is the replacement of 9G and 11G.

IIRC, Heath did the study comparing 60G vs. Duraterms. Essentially, as AK said the Duraterms glow much faster in a short period of time.
Then it is self limiting after that.

I am not sure if the thread is still here or on the other forum.

The bad of 9G and 11G is that it swell if you put them on extended glow. Then it cannot be pulled out when you want to replace it.

We have ice and snow in Dallas TX now and temp less than 20F probably not as bad as AK.
I am glad I have Bosch Duraterms. It did not have any challenge at all when starting with stock ECM.
 
I have the 60g's in my 95 LD. I have the max glow in the programing. It isn't long enough to get full heat out of them. I'm switching to bosch but haven't used them yet in any that I put them in. Bosch is supposed to heat much faster.

I have 60g's also, only changed the easy 4. I could use an entire overhoul including the wires and harnesses that the vender here makes nicey nice. Summer job.

She starts fine, ugly, but easy. After all its a diesel, i always thought it was supposed to be a loud and ugly start unless its plugged in for 3-4 hours then it purrs like a kitten. However, I'm too cheap, so I give it 1 hour of plug in, then loud ugly start. Hasn't failed me yet.
 
I noticed no difference from 60gs to Duratherms. I call placebo effect on that one. I have swapped to DT's on 3 trucks and no difference on any, in fact the CUCV starts a little harder but that could also be a failing IP.
 
I would not reccomend extended glow time on a 9G plug. I tested the ones that came out of my BURB origanally, and at about 3-4 seconds they were hot. At 8 seconds they were glowing BEYOND cherry red hot, and at about 9.5 seconds they went POOF and exploded. I did this with 2 different ones and both ended with the same results. The WAPS when new are pretty fast heating, but we all know how they end up after a short period of time. Teh 60G's required quite a bit of extra glow time VS the 9G's even in the warm weather we have down here in FL. Never tried DURATERMS.
 
My Bosch plugs would get hot to 1/2 way in 4-5 seconds when I put them in.

The 9g's I took out were slightly slower to that point but as Ferm said they kept getting hotter. I never let it go until it blew though.
 
Hum, I was contemplating replacing the glows in the 6.5L.... I'm at least going to pull one and see what model they currently are.
 
The great thing about being self regulated is that they wont overheat, but stay hot and warm up the metal in the precup as well. If I have to change a set of GPs every two or three years for smoother starts every day thats fine by me. So the longer glow is not just to heat the GP, but the rest of the combustion chamber for better cold starts without the block heater.
 
Had stock acd's in my truck when I bought it, can't say what they were, didn't look.

Started OK, smokey sometimes when cold. Changed 'em out because it would take too long on a crank sometimes.

Swapped in 8 new Duraterms.

Starts each time, every time, not even noticeable smoke. Only been down to -5 without plugged in so far. No more problem than the usual clatter. Always starts within the first 2 secs.

Only time I even get a "puff", it was usually a fail to start on the first attempt (usually my fault with letting key off too soon).

My engine is also very high mileage, sitting at around 300-350,000 kms. Blowby is "phenomenally" huge. the Duraterms still kick 'er off every time.

Your mileage may vary.....
 
Thanks all. Just exploring options before I pull fuel injection stuff.
