How much power will -8 hose be good for with e85?

I know -10 would be better but I normally run 93 pump so already have the -8 hose installed/using

Question is how much power are you planning making?

buick_lsx

well im just running gas right now, and at 9lbs im making 600rwhp...wanting to up it to around 12-14 psi here soon and would like to do e-85. If the -8 wont support say another 150rwhp ill just stick with some 110 gas.

And since were alredy here, if i do go -10, how much will that support e-85

A -8 will flow a lot of fuel... over 1200rwhp on gasoline. I would say 1000rwhp will not be an issue on E85

I have both dual pump kits & injectors in stock... plus teflon line for E85.

Feel free to give me a call.

Do you need Teflon? I have the stainless braided hose now but I'm guessing it's just rubber inside?

Many claim that you do not need Teflon, but I have seen a lot of other rubber based hoses get very stiff in a short time or smell due to the fuel penetrating the hose.

Braided hose will also break internally if brittle, as the only strength is in the outer layer of stainless. When it gets stiff, change it before you end up with a fire.

Great info. I'm getting ready to run fuel line for my project and I'm at a tossup if I wanna run #8 or #10 feed and 8 or 6 return. I'm running a Aeromotive Eliminator pump (in tank) and Bosch 160lb injectors. I have Teflon lined #8 already, but I have access to rubber braided #10 line also. I'm gonna stick with pump gas with meth injection. what do you guys think 8 or 10? I don't plan on making much over 1000rwhp, but you never know.

What Lonnie said^^^^
I see the results of E85 eating the rubber hoses when I clean injectors that are run with that fuel..Black crud in the filter baskets...

The fuel vapor penetration was horrible with mine - I've had some Earl's Perform-o-flex lines up front and out back for the better part of the past 2 or 3 years (I can't remember at this point), and the lines really started to stink after the first year or so. It wasn't much of an issue because I used to live in an apartment with a detached garage, but ever since buying a house with an attached garage, I really started to hate walking out in the garage every morning and smelling it.

Even with the E10 we have around these parts (no other choice), there were tell-tale signs in my fuel bucket in the tank that the rubber lined braided hoses I used were being eaten. Although I didn't get a picture of it, the feed on the top of the bucket had black crud in it. I was less than pleased.

After the past couple of weekends, all of the lines have been replaced with Goodridge PTFE stainless braided hose...here's what the top of the tank looks like now (this is just after I got done doing my Racetronix install yesterday):



The Goodridge PTFE lines are actually really easy to assemble provided you can keep the stainless braid from flaring out on you after cutting it. I had to buy a cut-off saw from Harbor Freight since the cutters I was using on the rubber-lined hose didn't do a good job on the teflon line, but other than that, it wasn't too bad. Just retardedly expensive.

You wrap it in tape before cutting it. Install the nut, then remove the tape.

I keep these lines in stock if you want PTFE hose & fittings.

We made over 800rwhp on stock 3rd gen line(3/8) with e85 on 18lbs and ran the same setup on 23lbs, I'm sure it was making well over 900rwhp. I'd think 8an would be good for a lot of power on e85. Also was running stock rails and 80lb injectors, lots of fuel pressure, and boost a pumps on twin walbros.
