Going E85

[VenemousStang]

So I gave in to the idea of the return system on my cobra. I will be going that route just trying to figure which is the best setup. Anyone know if I can use the stock feed fuel line and use that as a return line with my already upgraded -8 feed line I already have? Currently have twin gt pumps but will probly upgrade to 2 of the 465lph pumps from lethal, also a regulator and ID1000 injectors. What you guys think? Or should I just go -10 feed -8 return? what kind of power can I make with each setup? Looking to make around 850hp

if you already have a -8 feed i would go ahead and run either a -8 or -6 return and be done with it.

What's the best way to route everything for return style?

 

[VenemousStang]

anyone have some underhood pics of their return fuel system? how you guys routed everything

Don't mind the mess I am changing a bunch of stuff under the hood. I have got my -10 feed line running on one side of my FLSFC and the -8 return line running along the other side they are both on the passenger side sub frame connector.

-8an feed and 6an or 8an return is more than enough. I ran 10 feed then 8 in the engine compartment the 10 return. Put the FPR after the rails.

I'm using a -8 feed and -6 return. Thats ideal but you can run bigger if you have bigger plans down the road.

Thanks for the info. I will def be putting the regulator after the rails. Gonna try to go into the rails from the back then out the front into the regulator and back to the tank again

I'm new to all this and was wondering what it takes to change to change to e85? Parts, expense, etc? Also pros and cons

 

[VenemousStang]

It's about 30% more fuel that's needed for e85. Do depending on your power goals you will need pumps injectors fuel lines accordingly.

I agree...
I run 8 in and 8 out never had a prob. 88mm turbo. You have to be making close to 1400 hp to actually need a line that big.

From experience I have ran 8 feed and stock line for return with 750 hp a race gas.

I run -8an feed to stock rails, FRPS adapter to regulator, then -6an return. Click each picture to view in high res.

Is it necessary to run a Y block after running a single feed up to the engine compartment? I was thinking of running a -8 up to the rails and putting a T on the passenger side rail and a 90 on the driver side rail. Would that be ok or would it starve the driver side rail?

Im using a -8 feed and my stock feed line as my return, going to the dyno may 7th for the mods in sig below, should be enough
