fuel management questions for turbo

I am fairly new to turbo's, for a carb application anyway. I was wondering on the blow threw carb/turbo set-up if it is possible to control how much fuel the carb puts out, at idle and WOT. Would a FMU like the Aeromotive Billet Digital Fuel Management Units - AEI-16303 work well? Sorry for not understanding but I am just having a hard time finding the safest way to deliver fuel to a non-computer controlled car and being able to regulate it. Any help on the fuel part would be much helpful. If anyone has any info on the ignition, that would be helpful too. Also if anyone knows where to get a nice bonnet for the carb, that would be helpful also. BTW, I have a 66 ford mustang coupe, 200ci, automatic. under construction.
 
Well, I would start out by searching and reading on this forum. A lot of this has been gone over already.

I actually just went through this, and finally got it working.

They key to making your carb work properly under boost is maintaining a constant relative fuel pressure. IE, if you raise the pressure the carb see's 5 psi (5 psi of boost) raise the fuel pressure 5 psi. If you do this, the carb will work pretty much the same as it would w/o boost.

Now, I dicked around with a few different ways to do this, but in the end, I ended up buying a good quality fuel pressure regulator w/ boost reference port, installed it, and my system started working perfectly.

That's all a FMU really is anyway.

For ignition, I am just using a DS II w/ MSD 6AL. I haven't gone the BTM route... I can't really stand on too much of a pulpit here 'cause I don't have this working perfectly yet - but a lot of what you need here depends on what your goals are.

As for bonnet, there are a few places that sell them, but it's an easy thing to make. If you aren't a good enough fabricator/welder to make a carb bonnet, a turbo setup probably isn't the right choice for you in the first place.
 
Thanks for the information. As far as the carb bonnet, I probably will make my own unless I find one cheaper than a custom made one. I am a back yard mechanic for over 20 years, taken cars completely apart and rebuilt. Have done arc, mig and some tig welding and if not my friend is an expert welder, he built some of the ferries to Nantucket. Once I have all the info, a turbo install will not be a problem.
 
Well, from my own recent experience I can tell you that a turbo install is both easy and hard :)

It's easy in that no one part of it is exceptionally complicated, and having done it now once - doing it again would be a breeze (will I ever own another NA car?).

However, it's hard in that there are a ton of little things that need to get done, and it can be really hard to keep track of it all.

:thumbup: Experimenting is fun.....if you think things through.

Of course, sometimes that is how we get the knowledge to think things through....by failed experiments!
 
Not that I really know a lot about turbos but a little word for the wise.
Edison failed 2000 times at inventing a light bulb and when asked about it he simply said "I didnt fail I found 2000 ways not to make a light bulb but I only need to find 1 way that worked."

Yeah he resorted to copying Sir Joseph Wilson Swan's invention instead.

lol.

Always works. I should also mention that hardly is anyone here inventing a light bulb. This has all been done before. If you want to re-invent the wheel, that is your business, but don't think you are off being oh clever and inventing something new.
