F.I. BBB462 in my 86 Regal

Pic of my latest set up i'm playing with:

 

looks good
whats with the accel pump arm?
a 1050 cfm setup would be nice on my regal

 

The pump arm is in place for the throttle position sensor, and provides provides spring resistance for throttle return, there is a spring under the pump.

did you setup the manifold yourself.
i see you have a late model alternater. how does yours line up
mine is off some and had to use a double pulley

 

Maybe I'm looking at the plumbing weird because of the picture, but your regulator looks like it is not plumbed in correctly. Which directions does the fuel flow? Where is the return to the tank?

Bob....the inlet hose (pressure side) is routed all the way around the front of the engine, down the driver's side and looped around to the rear of the pass. side rail, up and across over to the driv. side rail and back to the regulator (all at FULL pump pressure). That appears to be a return-style Aeromotive regulator and those do have the inlet(s) on the sides and the return out of the bottom.:TU:

 

Very cool, Kerry! Only a warning if you're relying on the accel pump for throttle return by itself; I've seen both the pump shaft & pump linkage on the q-jets bind at one time or another.

Keep us posted...

If that is true, at WOT I bet he will see a big difference in fuel pressure between the #8 cylinder and the #7 cylinder. #8 will see the most pressure and cool fuel, and by the time fuel reaches the #7 cylinder it will have heated up quite a bit and the pressure will have dropped to where the regulator is trying to control.

I know it isn't a perfect solution, but I would much rather see the fuel flowing in "parallel" through the two rails, and have the regulator fed from 2 sides in the back (I think that regulator has 2 inlets).

-Bob C.

 

I totally agree Bob....I would have ran the pressure line to a "Y" at the front of the engine then on to each rail, and finally utilize the regulator's (2) inlets at the rear. This method will evenly "split" and equalize the fuel pressure and temp. much more efficiently and effectively IMHO.:TU: Would have used a lot less braided hose too!:grin:

 

Here is a pic of the intake after modification, it is hard to see in my first picture.

I'm running Accel 30lb injectors at 50 psi, Aeromotive boost vaccum/boost return adjustable fuel pressure regulator. Megasquirt v2.2 board and software and relay board, and lots of tuning. I have plans on getting it back to the track this time with the FI to compare to my last runs with the EDDY. Q-jet. I ran 12.83 @108 with 2.75 gears in the 9".
