the distributor is locked and set at 12 and running a 12 split and running br10egb , scattershield is on the car but i have to trim is hiiting the 4" downpipe and steering , and i havent made it the track yet but as soon it hits boost it sits you back , im sure i can pull more horse power out of it but im pretty happy with where is at should be enought to pull a descent time

thank you , armyofone exactly what is your set up , i used to run a 650 dp but i move to a 750 annular boosters becouse of the way fuel is being sprayed

Not bad for a lil blowthru project , all this was done at my one car garage , from engine to rear end , funny how you don't need all that fancy computer tech or tuner. To pull some descent power out of a rotary, I always believed in stick with what u know

I'm using a GT35 with a 1.06 hot side, 50mm WG, feeding with an Aeromotive A1000. Crutched setup run off a small air pump controlled by an adjustable pressure switch on the hat. Blocked secondary power valve and primary pvcr's open to 1/16" AFR is. 11.3-11.6 at 10psi. Only thing I need to finish up is either air seal or mechanically seal the throttle shafts. BTW I street drive this setup, that is why I am trying to make the 650 work.

Armyofone , I also drive the starlet in the street , i drove to the dyno And is about 40 minutes away , your set up is almost the same as mine. I'm also running a crutch set up. Running a small pump to open my secondaries power valve. pvcr is drilled to .094 , And running a adjustable switch on the hat . 1/2 in fuel lines and a Weldon fuel pump . The difference is that I'm running e85 And. U need annular booster to deliver that much fuel.
The carburetor started as a blowthru demon 650 but I changed to e85 and changed the center section to a proform 750 annular and then did all modification to convert to a crutch system wich lets u control when u want the power valves to open

nice work on the car.
i'd still be a little weary of the jetting though, i saw the wideband spike to 14.1 under full boost at one point but it could just be the placement of the sensor or the calibration.
the saying stick with what you know always works best, i'm sure there's more left on the table but not like it is needed just yet.
