Default 42lb injectors

Anyone have the flowrates for a 98 with 42lb green top injectors? I've tried using search, it just goes to a white screen.

Hi Black02SS

I find the numbers below with my calculation for my Lucas 42 lb. per hour high impedence fuel injectors
These fuel injectors will flow 42.5 lbs. per hour at 43.5 psi, my car is a 2002 ZO6.
I use those value, is there something wrong?

Your Fuel Rail Pressure: 58
Injector Rated Flow Rate: 42.5



0 49.08
5 49.38
10 49.69
15 49.99
20 50.29
25 50.59
30 50.88
35 51.18
40 51.47
45 51.76
50 52.05
55 52.34
60 52.63
65 52.91

Yours are correct. I used 42lb on the one I posted as yours is 42.5. It is a small mistake on my part. Good catch as I don't see it being that much of a issue.

Slight problem I should have mentioned, I was using Edit so the readings should have been grams/sec (20-100kpa) the readings you all are listing at pounds/hour, and 0-80kpa.
