I have a similar question posted in air and fuel but I was wondering from a tuning aspect... are 80lb/h injectors to big for a heads cam 346 on e85?

Could get away with a little smaller. My heads cam 346 needs 62# on e85.

Best bet for that combo is the GTP injectors. They flow 42#'s at LS fuel pressure, are EASY to tune, and work great. They will support ~500hp. I have a used set for sale, and they are cheap. Not just mine, but across the board.

Well the thing is I already have the 80's from my planned turbo build... just didn't know if they would be too much?

Remember that that injector is probably 80# @ 3 Bar. It becomes around 92# 4 Bar. But it will be tuneable on E85.

Is there such thing as to much injector? I know nothing about tuning.

ive tuned a 4.8 on 160 lb injectors on e85 factory pcm..80s are easily doable.

80s and E85 will be fine.

What pump are you running? Walbro 450?

That was going to be my next question over at air and fuel. If there is a specific e85 pump other than AEM.

So I guess I won't sell the 80's which is good because it will give me options in the future.

450 can fit in the stock canister with some modification. It will likely overpower the stock regulator but it'd otherwise work with your fuel tank without much issue.

The stock hard lines might work with E85? And since you won't be pushing a lot of HP, might provide enough flow. But, if you end up having to go with new lines/rails then you can go with a FPR and mount it by the engine to alleviate the high pressure issues the 450 would cause.

I have tuned them to a 15 AFR in a stock 5.3L on pump gas.
Should be easy to tune them for a 5.7 on E85

i have id850s at 4 bar on a 4.8 on 93. 80s on a 5.7 with e85 should be cake.
