Here is a link to an article that tells you how much horsepower you can make with different sized injectors,at 100% duty cycle (scroll to the bottom for that info, the math equations to figure it out yourself are above it) : https://www.boostedrps.com/single-post/2017/08/25/How-To-Calculate-Your-Fuel-Requirements-for-Gasoline-and-E85

The real question we need to know before anyone can safely answer you, is how much power are you looking to make?

A 340 will work with E85 but only for so much HP. As you'll see in that article, for 600flywheel HP you'll need roughly 85lb injectors, so 80lb injectors will work for roughly 550flywheel HP.

Hope this helps.

The link was helpful info, or my response was?


hahahah "moist" .... Trust me, once you reach 450, you'll want 500...then 550....then you wonder what happened to your bank account! hahaha

So I'm curious, what is your setup on your car?

...you made 379rwhp and you have the dual fuel pump setup for 680LPH??

Are you planning on making 1,000hp on E85 or something? Who told you that you needed to spend $800 on a 680lph fuel pump setup?!?! Wtf?! Dude a single 450lph would be FINE, if you needed a little more, then add a boost-a-pump! 680lph?! Dude someone took your money and clearly doesn't feel bad about selling you parts you DON'T need...

what happened you didnt like e85? ok cool hopefully it can handle 20lbs
thanks
I re-cammed the engine and the flow I needed to keep running E85 was more than the fuel lines could feed, so I switched back to gasoline. If I ever get around to upgrading the fuel lines and pump, I'll go back to the corn juice in a heartbeat. I can walk to a station that carries it and it's all over town here.
