WOW ! There sure is a whole lot of posts about pipes and glowplugs.
Honestly, if you really want to know just what the differences are
in them and what is going to work for you. The first thing you have
to do is take the engine out of the box and actually fire it up and
run it youself. What works for some may not for others. I see some
mention about some people trying to run these engines on what
seems to be lower quality, bull sh-t, fuel. Why would anyoine take a
hi-quality engine and try to run it with cheaper low-grade fuel ?
Then come on hear admiting it and get into some big discussion
about what glowplugs and pipes will work with this rather unsavory
combo.
Sure, running hotter glowplugs gives an engine a wider tuning window
and makes it easier for the novice to find a tune and it may be what's
required for a engine to run properly on some kinds of bull sh-t fuel.
But hotter plugs have a weaker coil and burn up easier. All it takes is
one glowplug coil to drop into a cylinder to ruin a piston and sleeve.
So, running ultra hot glowplugs just to save a couple of bucks on the
fuel may cost you alot more money in the long run.
I'm not trying to say anyone is going about things the wrong way,
to each their own. But some times using your head for more than just
hat rack will help you out in the long run.
