1996 mustang hydraboost setup.....to go with my 96 mustang front and rear disc brakes that are going on.
I have finally joined the club!!!
- Thread starter XFlow_Fairlane
- Start date
this is the current setup. I am picking up an intercooler and some AL sheet in a couple weeks to fab up a front mount for it.
below is the oil supply I used form a 2.3L ford
excuse the oil....I forgot to tighen down the VC before taking it for a spin...got it all cleaned up now though.

Looks like a great beginning for a first timer!!
Boost gauge yet?
Boost gauge yet?
gotta pick one up still.....gotta remember I am doing this during my last semester of my engineering degree....on a part time student workers payroll.... driving it seems to be doing ok....just a real bad dead spot right off idle...if you crack the throttle just a hair it will die in this one little spot.....I tried turning the idle up past it and it will just die when you hit that spot.
any ideas?

float level
accelerator pump
cotaminated metering wells
air bleeds
the pump squirts....so do I just need to adjust the lever on it to have no play?
the funny thing is that it does even if you roll on the gas real slow (like turning in the idle speed screw) well I am getting the hang of it....just mash the gas and go

transition circuit problems
well what do I need to do to fix this now? float level? idle screws? I wasted $15 on one of those haynes holley books form autozone...POS is just a collection of carb rebuild instructions basicly....

raising the float level will help.
Its too hard to explain
Its too hard to explain
ok...I know mine is a little low so that would explain some of it. so as the airflow past the throttle plates increases and mains come into use does the idle circuit die off at the same time? I could see how float level would effect this as the pressure at the jets on the mains would be lower requiring more airflow before they "kick in" I currently have my float at the max on the seat adjuster (after my little right hand rule error) so I will drop the bowl tonight and redjust that back better. I would love to get this car dialed in better this weekend and maybe hit the local 1/8th next weekend or the week after before it gets too cold (although turbos do love cold...)

Exactly. As the mains pick up flow due to more throttle opening, the idle circuits stop flowing.
In your case the idle circuit is dying before the mains pick up.

so would a low flow level require too much velocity in the venturi to get a fuel flow than the motor has off idle then? and raising the level will reduce this "jump" in there? when adjusting the float level I pull the sight plug and raise/lower until it just barely wants to weep out right?

The discharge nozzle in the carb is higher than the float level. NOT by a whole lot - - buy high enough so fuel won't run "over" by gravity.
If the bowl level is too low, a lot more airflow is needed to get fuel flowing "over the hump".
se figure "D" , it is the closest to what we are talking about.
It has
1) idle slot (throttle closed)
2) transfer slot (whaT you are haing problems with) and
3)main circuit

Off-idle circuit
As the throttle is opened up slightly from the fully closed position, the side of the rotating "plate" that moves forward as it swings open uncovers extra openings similar to that of the idle circuit. These allow more fuel to flow as well as compensating for the reduced vacuum at slight open throttle.
