Fuel system requirements e85 500NA Hey all, so I'm running a 383 stroker ls1 and wanting to know what all is needed for e85 for NA up to around 500hp, as of now I'm at 445 and it's plenty, only saying 500 for a little cushion. If I want more at the strip I'm thinking just a wet shot.(saying this so we know the max I'll need out of injectors) max for lines/pump might be a bit more.
So what I seem to have found so far hat I'll need -80lb injectors (currently have fast 39lb)
-Dual walbro 255s? There seems to be some variability in suggestions here, I love cheap but I don't want to half *** it. I don't plan to boost this car, 450 is enough for daily for me I don't really want more (I know I say that now..) I sometimes here about the 450... Then see not too... Idk. It's a street car that will see autocross and fun strip use. Mostly just a pleasure car.. I would love an easy to install fuel pump situation.
I currently have ls2 fuel rails... Are those rails and my stock fuel lines enough for this?
My goal here is to play with my car to learn about tuning/data logging etc.. And I want to learn about alcohol as a fuel.

I assume you mean 500 rwhp? If so all I can tell you is that my 42's were at 85% duty, and single Walbro 255 with hotwire kit was holding up fine as well, and I'm around 460 rwhp. All on E85

It should be a 255 I would assume, and from what I understand the hotwire kit is good for another 50 hp or so. The one I got from Lonnie's Performance was a Racetronix single 255

Hmm I'll need to look and see if it has the wiring harness as well. I feel like it doesn't but I'm not sure. I'm guessing that probably wouldn't hold up if I went for a nitrous shot down the road though... Hmm
And oops my currents are fast 36s
