Who has used 1600cc Injectors

Holy shit, your flowing 87lbs/min... Is this in the GSX and I sure hope thats not what you ran when you put down the 11.3 at RF?

Thats nice to know about the duty cycle. What gas are you using and what size fuel pump?

Yes that was in the GSX, however these numbers were achieved after I added the Magnus Race Intake Manifold and a Q45 throttle body along with 3.5" intercooler piping. I Didn't have a chance to make a clean run after these additions last season. The 11.3 @ 133.7 pass (note the mph with my stock ass suspension and 18" wheels lol) was flowing around 73 lbs/min...

Hoping to improve on that significantly this season ;)

Is that by choice? Or because of the injectors? My ISC is flakey right now and idles at 1500 rpms. Even that can be annoying in stop and go traffic.

Nice airflow numbers!

It has more to do with my cams, and the fact that I don't drive on the street all that often. I could probably get it down into the 1500 range if I wanted. It's also important to note that I do not have an IAC motor any longer and change idle speed by the BIS alone...

The lb/min numbers aren't going to be accurate unless you have a 100% stock 2g MAS on the car.

You are correct I am using a GM MAFT, thus the numbers cannot be 100% relied upon in regards to lbs/min. However, as you may remember we spent many hours on elite's dyno removing and replacing the stock 2G MAS to get the airflow correction as close as possible...

Anyway, I ordered 1600cc injectors from FIC. I appreciate everyone's input and I'll let you guys know how they work out for me.

Just thought I'd bring this back from the dead real quick as I just installed my PTE 1600's. I've found mine to idle best right now at 70% Global and 375 deadtime. I've been searching and searching and can't seem to fine an exact number to use as far as deadtime goes on these. Generally I found people running anywhere from 350-400 (and 1 case of someone running FIC1600's @ 180), and anywhere from 65-75% global. The equation from the Link forums was (450/1600) - 1 = ~72%. So that's where I started, but ended up getting my best idle at about 70%.

This is still on 92 pump. I just wanted to get it running somewhat decent on pump, before I start doing full E85 here shortly.
