Almost ran the tank dry of 89oct on the way home tonight...and I swore to myself that when I filled it up with e85 I was gonna take it easy...I swore.
Well, with the waste gate inactive at the moment, and a full tank of e85 coursing through my fuel lines...I listened to the devil on the shoulder and floored it after a few miles of driving.
Almost blew everything to hell :roll:
Duty cycle was maxed on my little 380cc injectors at 12lbs of boost and 4800rpm. AFR went to 22.0, the car did a nose dive, and I don't know how things are still together. I drove it around for a bit and made sure all was well. Went into a few lbs of boost to make sure it was all still working, and drove home for the night.
Now the hunt for bigger injectors begins. I'm also starting to think that the Garret T19 turbo that I am using is a little too big. With only ~400 more RPM to go, I don't know if I could even get to 20+ lbs of boost.
I'm just gonna count my blessings and take this as yet another big learning experience.
Log attached for those that want a look...beware, it's cringeworthy

Negative...even though you already mentioned that once already. I'll make sure I get it set up before something like this happens again. Would it be quick enough to be able to prevent something like this from happening?

It can be. Just depends on how aggressive you set it. I've had it too aggressive in the past, got tired of it, turned it off, torched cylinders. It serves its purpose.

So I've been running the E85 for a week now. Haven't been able to push it to 20lbs yet because of my injectors, but it seems to be running flawlessly with a seamless transition from the 89 Octane I was running.

Now that I am in the market for new injectors, I have been glancing over Ebay and the like. I assume that most of the injectors that I have been looking at for Subarus and Hondas will work for me, regarding the style and fitment, but I just wanted to double check with you all.

https://www.ebay.com/itm/4x-Subaru-820c ... 9501!US!-1

I would guess with the correct gaskets that most injectors could be made to fit correctly, but wanted to make sure. Also, are 820cc injectors too big for my motor? I checked an E85 calculator online and it said at 80% DC that I could do 250hp at the wheels with 735cc injectors. I don't know if there are any low rev or idle issues with too big of an injector. 250hp is about all I would want to do with my current set up. Just wanted to make sure they weren't too big for idle and low rev cruising.

I will be doing at least 1000cc with my 1641 on e85. Might go bigger...

Are you concerned about low rpm issues? Guess its just the quality of the injectors too.

Not at all. My 1000s are nice injectors, well known for their ability to control fuel at very low rpm and with small cc.

I've only done a couple fill ups with E85, but it looks like I'm getting ~22 mpg. Yikes. I guess that's ok considering the fuel, but it kinda sucks getting gas every three days.
Had to channel my inner MacGyver yesterday when my throttle cable busted at the pedal right after leaving work. I was able to scrap some parts together and ended up crimping a small ring terminal on the broken end, and then zip tied that to the roller pedal. Babied it all the way home like that for 30 miles in traffic till I could get home and put a little bigger hardware on it. Looking to pick up something a little more heavy duty this time around, as that cable has only been on for a few thousand miles.
I ordered the 820cc denzo injectors off EBay, and I'm really hoping that the O-rings they come with are correct for my fuel rails and endcastings. If not, I'm sure it will delay everything by a few days. Really looking forward to getting up in the 20lbs area :twisted:
