Just curious if anybody is using a large single fuel pump setup on their Silverado with e85 making around 750-800. It seems like most people are running dual pumps at this power level. I would like to maybe use a Magnafuel single pump or something with e85 but just wanted to get some opinions. Thanks.

 

I'm running a single walbro 450 on e85. It's a 4.8 with a cam and a procharger and makes right at 500 to the wheels.

 

Unless you plan for less than 600hp or so you are going to want a large pump or dual pumps.

 

I used a single 255 with a 17 volt KB BAP on E85, took me to about 540 rwhp.

 

I'm planning on 750-800. I guess I should have worded the original question as "Is anybody using a large single fuel pump" as that is what I meant.

 

I would think you would need something like a A1000 with controller or maybe one of Holley's 2 in 1 Dominater pumps for that kinda fuel. Don't think a wb450 is gonna get you there.

 

450 with the relief valve punched in and a boost-a-pump putting 18v to it got me in that balkpark using e85.

Dual pumps are cool until one fails.

 

I run a single aem 380 on my street nova on e85. 6.0 ,s480,glide,3.23 gears. I don't know the hp but it runs 10 teens at 135 mph at 3600 lbs on 12 psi boost. it is not out of pump yet . still holds solid afr down track.

-6 feed to stock truck intake/rails at 54 psi static. 5 1/6 return.

 

I'am using a single walbro 450 and making 535. I am planing on turning up the boost to 12lbs with the hopes of making over 600. We shall see.

 

I'm using a single Walbro 450 part #F90000267 and a Kenne Bell 20V BAP and E85 and made 650/627. This is where the pump was maxed... dropped 1psi @ 14lbs and 2psi @ 15lbs. When I get time this week I'll be putting in the F90000274 in place of the 267. I like the simplicity of the BAP and single pump.
