Anyone tell me what lbs/hr the stock TII (88) injectors are? Look like same bosch style as GM Tuned Port.

 

550

 

About 50 lb/hr.

550cc/min (~55lb/hr) at 250kPa.

 

The multiplier is 10.5.

550 / 10.5 = 52 lb/hr.


-Ted

 

550 cc/min = 0.55 L/min = 0.405 kg/min = 0.894 lb/min = 53.6 lb/hr

Assuming a density of 737 kg/m3 for petrol at 16degC (60degF).

 

And the size of all the RX-7 injectors is in the FAQ.

 

Hmmm...



0.55 (liter / minute) x (60 minutes / hour) = 33 (liters / hour)
33 (liters / hour) x (gallon / 3.8 liters) = 8.7 (gallon / hour)
8.7 (gallon / hour) x (6 lbs. / 1 gallon [gasoline]) = 52.2 (lbs. / hour)
I typically use 6 lbs. per gallon of gasoline. :P
Close enough!

Your fuel density figure is a little low. A quick Google search found 737 kg/m3 in a few places, which is 6.151 lb/gal. But like you said, close enough.
