Anyone know if Stu or someone has written a concise guide on injector sizing?

If not, anyone care to enlighten me?

Cheers

From what i can gather...

(Horsepower x BSFC x 10.5) / (No of Inj's x Duty Cycle) = cc/min

Working on the following:

80% Duty Cycle
5 cylinders and hence 5 injectors
BSFC of 0.6 (which I believe to be correct for a generic FI estimate)
Target of 400bhp

(400x0.6x10.5) / (5*0.8) = 2520/4= 630cc/min ?

I guess that rules out 1.25 sets of VXR injectors unless I want to run them in excess of 5 bar (I dont)

First off Are my calculations correct?

Secondly, any ideas on where I can get such a size of injector without remortgaging my house?
