10.6 @ 129 mph!!!

:P
In My Mustang ;)

I did undertake a new project for the Capri though.... building a 347, big cam, gt40p heads, stock ported intake...

gonna try and keep it speed density with bigger injectors....

If you understand how speed density systems work you would NOT attempt doing this UNLESS you have an aftermarket computer that is programable. The speed density system is based on a fixed value of known variables, if you change the airflow, the computer has no way of knowing this, therefore it cannot posible adjust fuel or timing.
Thats why the mass airflow meter type system IS able to adapt with larger injectors and a matching mass air meter; it measures the actual airflow and sends the appropiate commands to the actuators.
I had a 331 cu in injected engine with a paxton blower with 10 pounds of boost, it made just under 600 HP, using 50# injectors and a ProM mass air meter. It ran fine, 10.92 @ 128 MPH, and could actually have been street driven, provided I had more cooling system.

wow that is a surprise to see ed from windsor-fox post here. One of the pioneering EFI gurus of all time.

hello ed! :mrgreen:

I can do a chip for it easily....

Some people don't have much luck.... I can't see why it would not work considerig the adjustable paramaters.

I too have a mass air meter Mustang that has gone 9.79 at 139 mph and purs like a kitten.... but I hate mass air and see no need for it.

I'll try speed density this time ;)
