Oh you kids. :wink:
I just can't help but think of fuel injection as sticking your straw in the bottom of your soda and sipping exactly as much as you want, and carbs as putting your straw on top of an ice cube and sucking a few drops off the surface! :laugh: I guess it works well enough for hot coffee, though. :smile:

I am of an opposite view. With carbs, you suck as much as you want, with injection, the voodoo decides how much for you!

And mine REALLY sucks!

(No, wait - that didn't come out right...) :blush:

If you are so inclined, you can build a megasquirt fuel injection system fo the GT6. Then you can program and map all the voodoo black majik stuff you want. :devilgrin:

I'll stay with carbs for now. :yesnod:
 
I work with computers all day and when I go home I want something I can understand. So a carb is the way to go for me. The only problem is I don't understand carbs either.
 
How about fuel injection that looks like carburators!!

These little percolators aren't all that hard to understand. You're just controlling the leak from areas' of different pressure, that's all.

Back when I was a youngun, we studied the inner workings of carburettors designed for altitude compensation, that didn't care what way was up, and could flow a little over 150 gallons in an hour. Three throats you could fish your arm through to find the little part you dropped.

Drat, linkee no workee, anyway look up "wasp major"
 
Richter,

Don't think the fun stops with the megasquirt. They have a megajolt DIS system on the market. :yesnod:

With the complete package you can have full control over the Voodoo. :devilgrin:

There are a few guys running these systems over at the NASS group.

Don't get me wrong, I think the carbs are cool, and I want to keep it original, it's just a whole new thing for me.

Fuel Injection just seems so easy for me, caveat: As long as you can control it. If your car needs more fuel, type a bigger number in the computer, it's done. :laugh: It's just a big table, one axis is RPM, the other axis is engine load. Get an o2 sensor and tune it for 12.5 or 13:1 (a little richer than stoich for ping resistance). If the number is higher, add fuel. If the number is lower, take it away.

What I'm not sure of is things like, if the carb is rich at say, 2400 rpms, and lean at 4000 rpms, what do you do?
 
Change to a more appropriately tapered needle. :laugh:
 
Many of the guys here use the ColorTune system to see if it is rich or lean. It takes all the guess work out of it.
 
For give me if I've lost the thread here, but with everything else you have going on the with car here I'd suggest that spending a couple of hours (tops) and $80 (tops) to rebuild the existing carbs and use running those until everything else is sorted might be a good idea. I'd be leary of having too many moving parts (so to speak) until I got a good baseline. Once everything else is running correctly and provides a good base for a healthy EFI conversion you run the risk of chasing your tail.

Thats the plan. That is the route we're taking. We just brought it up because carburetors are an outdated, inefficient, and forgotten form of machinery. We do have a brand new megasquirt lying around the house though.

We almost got ourselves in trouble sunday. We had the engine pulled and on a stand, a stand that held a heavy v6 engine, even a v8 engine, but somehow got loose enough that when it held the I6 it tilted and fell on the cement floor. Took a big chunk out of the pavement, but the engine appears fine. We might have forced ourselves into an EFI non-triumph engine, but luckily everything appears fine.
