Default Accel 30# injectors multiply fuel by ???

I have my Accel 150830 30# injectors to go in my car and need to know what to multiply my flow rate v kpa table by. Any sugections or even a equation whould be great. I have seen many discutions on the svo30# and how they are rated at a 48psi. I don't know what psi the accels are rated at. Any help would be apreciated.

You need to know what pressure the Accels are rated at.

The SVO 30lb injectors are rated at 43.5 psi or 3 BAR... as are the Accel injectors... If you had 28.8s to begin with you need to multiply your factory IFR table by 1.203, effectively increasing the numbers by 20.3%

Here's an IFR table calculator.

2002.. 28.8s


1997-1998 LS1 / 28.8 lb injectors
1999-2000 LS1 / 26.2 lb injectors
2001-2004 LS1 & LS6(Z06) / 28.8 lb injectors

Here you go, this is a straight conversion from 28.8's to your Accel's...

Code:
MAP (kPa)	         100	 95	 90	 85	 80	75	 70	 65	 60	 55	 50	 45	 40      35	 30	 25	 20

Injector Flow (g/sec)	4.36	4.39	4.42	4.45	4.47	4.50	4.53	4.55	4.58	4.60	4.63	4.66	4.68	4.71	4.73	4.76	4.78

Hptuners, Why? Oh wait as I just tried to put those values in and noticed it is in Vac & lbs/hr. Are those the values in metric that fit the table? I changed my display units to metric but it is still in Vac on the top of the table so what should I do? Thank you Charlie!

I thought you did, by the way you worded the question. Charlie's info is for LS1Edit, if I am right. You and I have HPTuner. Just multiply your entire "Flow Rate vs. KPA" table by 1.203, which is what I did...

Good Luck,
