DIY_EFI Digest V5 #9:Injector mounting

[Carter Shore]

Cutting intersecting tubing and holes is not a new
problem, chassis and roll bar fabricators must do it
all the time. There is a widely used tool, ('ole joint
jigger, etc. ) that accomplished this task. It can be
adjusted for tubing up to 2-3 inches, and almost any
intersecting angle. Uses a standard hand drill with
common hole saws.

But since the Volvo used batch fire, as Grumpy pointed
out, why bother? What size motor was the Volvo? MGB
was 1.8L AFIR. Look up the flow on the 4 injectors you
have (Lucas, Bosch, ?), then find some compatible ones
that will flow enough for the MGB using just two.

flow req = (MGB motor)/(Volvo motor) x (inj flow) x 2

So if the Volvo was 2.2L, injectors 19 lb, then

flow req = (1.8)/(2.2) x 19 x 2 = 31 lb

Of course, this assumes similar VE, max RPM usage,
etc., YMMV.
