I'm considering getting a Boost-a-Pump for my Turbocharged '99 VCT Zetec Cougar, but I'm not exactly sure what the stock fuel limits are on the return-style fuel system?
Does the BAP work on a mechanical Fuel Pressure Regulator system?

Interesting write on swapping out the dual Cobra fuel pumps for dual FSVT pumps compared to dual Cobra fuel pumps + BAP. BAP svtFocus Test

I'm running a 255lph Walbro Mustang Fuel Pump. Pretty much a direct swap. It was the BBK-1607 for $130.
I also went with an Aeromotive 13102 fuel pressure regulator for $110.
Both would cost less that the boost-a-pump, not stress your stock pump, and be much more reliable. IMHO.
This is all assuming that you have converted to a return style system. (Weren't all Cougars return-less?)

My Cougar, which has a birthday of 5/26/98 is definately a return style system.
My engine is exactly the same as a '99 Contour engine. I know this because it actually came out of a '99 Coutour
So, what are the HP limits of the stock return fuel system.
Buttonpuncher, what is the need for the aftermarket FPR?

1999 Contours have a returnless fuel system.

If you have a '99 Contour that was built before 5/2/99, then it will have a return-style fuel system.
So, we are both right, a '99 Contour could be either.
BTW, what are the stock return-style fuel system limitations?

Remember, you want to keep fuel pressure stock while putting in bigger injectors to give more fuel. You only want to raise fuel pressure on a 1:1 ratio to compensate for the extra boost in the intake.
You'll want the rising rate fuel regulator to do that. What size injectors will depend how much power. 42lb/hr injectors will be good for around 200-230whp at stock fuel pressure.
More than 230whp or so, I'd go for the bigger fuel pump also. The main benefit of a return fuel system is when you're driving hard in the upper rpms where lag is minimal to non existant, if you go from low throttle to full throttle(ie. no boost to full boost), the ECU can't compensate for the sudden fuel pressure change as well as a mechanical system can.

The Aeromotive is an adjustable FPR. That way if I run out of fuel with my injectors, I can bump the pressure to compensate.
I have to totally agree with Seawulf. The throttle response with the Mustang fuel pump and the FPR is incredible. There is no bog anymore when I stomp on it. My Zetec just goes. Part throttle is also incredible. 
I'm not sure what the limitations of the stock return fuel system are. I wouldn't want to push it past 160-170 FWHP.
Now with the 255lph Walbro, I'm sure I will never get near the limits that it can provide. I wanted to bulletproof my fuel system before throwing my turbo on. I'm pretty sure that I've accomplished that goal. 
BTW, the Aeromotive is a 1:1 FPR. (It will rise equally with boost.)

I see, I wasn't aware that I could get a pressure-adjusting FPR for that price. I understand the need for an increase in fuel pressure when there is positive pressure present on the output side of the injectors. So, now it looks like I have something else to buy.
How long should it take to drop the gas tank and swap the pump?
