Having bank to bank fueling issues and maxing out the ID1000s. Need to bump up to something bigger. Reading that ID 2000s have issues and were not intended for petrol fuels. What are people running that has complete tuning data available?

George C....

what fuel are you on now?

C10 when pushing it. 94 E10 with meth spray for daily.

George C....

with maxing out 1000cc injectors you must be near 1000rwhp with that setup?

Well, that's all I was shooting for when I put it together. Was hoping for some better IATs though by not over-spinning the blowers. Theoretically, based on their efficiciency maps, they should be moving something like 2300 CFM.

I have the ID1300's and they work great. They have stainless internals, so will handle any fuel. Bosch also makes the 1650 injectors that have stainless internals, but I have never used them.

Have you swapped your injectors bank to bank to see if the problem follows?

Are you running primarily E85 or gas? ID states that the 1300s are designed for E85 and will provide good idle characteristics on that fuel.

I read a letter that Bosch issued regarding the ID2000's when they found out that they were being modified and used with gasoline. Stated that the internal seals are not compatible with petrol as they were designed for propane. Reading that the ID2000's seals will swell overtime due to additives like MTBE, reducing flow.

Figured I would just get a larger injector rather than swapping banks if I am going to have to go bigger anyway. Nothing is easy access on this setup.

ID 1300's will work fine

I primarily run pump gas, but switch to E85 when I want to make power since I converted my truck to flex fuel. When my wheels come in, I will be using much more E85. The major selling point to me was the fact I could swap back and forth between pump gas. When I got these dialed in, my AFR was completely flat in a log.

George C....

if you were only shooting for 1000rwhp then why are you looking at larger injectors unless you plan to run a different fuel?
1000cc injectors will support little over 1000 rwhp

now if duty cycle is high then check other things like fuel line size, fittings being clogged, fuel filter being gummed up or pumps not keeping up

as for bank to bank, are you sure its fuel issue and not say blower issue?

i havent looked at your at your log
