Title: I can't make soot!
Post by: hamradio on July 18, 2007, 04:32:51 pm

Ok.  I was so excited the first time I took out my rabbit.  I was going along, 5th gear, 55-60.  Coming up to a hill (a really slight little hill), and I put it into 4th gear, long before the hill.  I instantly looked back, expecting glorious clouds of black smoke.  Nothing.  I might have as well just been driving a friggin' gasser, for soot ability.  I know that my IP timing is a little off, as I did a tb change, and never set my timing again.  And I can start it, when cold, with the cold start pushed in (starts rough, but does start).  If I set my ip timing to the correct timing, will I gain the magnificent sooting ability?  

Also, a friend was driving behind me once.  I asked if I made black smoke.  He told me I just made a little bit of blue smoke, apparantly, the entire time (not just when I shift).  I drive with the pedal to the floor up to 5th gear anyway, so it might be something with that.  If I'd drive for economy, maybe I wouldn't do that.

You consider soot a good thing?  I guess it looks cool but for me the novelty wore off real quick driving my old Sportruck that smoked like a fiend.  

There is a fuel delivery screw on the injection pump that will make your ride more smokey, but remember that soot is unburnt fuel, every time I see that black cloud, I think of it as a green cloud (wasted money).

I usually picture red hot piston tops and a melting turbo when I see clouds of black smoke

Your top end could probably use a rebuild if it's always puffing blue smoke. It sounds like you have your timing right though, or at least pretty close

Yep, black soot = room for more boost.  Of course it could also mean youv hit the wall as far as how much you can burn with your current setup.  Nice discription Tyler, I have a visual off that. Time till detonation T minus 30 seconds and counting...29...28...

He has a NA, there is lots of room for more boost  8)

Like Darth Garry said, there is a fuel screw on the pump you can turn up and you'll get some serious smoke, or moderate depending on how far you turn it

you gotta adjust your pump starwheel+stuff like that
actually mine only blows soot before the turbo spools up.once it comes on,,it clears right up
 cruisin easy though if i flatfoot it for a second itll throw a puff

If you turn that fuel screw in (clockwise, if memory serves me correctly) about half a turn to a full turn you'll make some soot.

Watch out though, too much fuel is a waste. Ref blue smoke, bad rings or valve guide seals most commonly.
