i run a magnafuel protuner 750(4303). im making around 950chp. ive seem one pushed to 970whp on e85 with 127lb injectors. Anything over 1000whp with e85 id probably go belt drive or multiple 044's or walbro 485's.

Interesting. Van383 who has gone 4.92 runs 2-A1000's and 160lb injectors. He has to be close to 1500 to the wheels.

I hear mixed information on this. The aeromotive ones are not compatible and seem to clog up rather quickly however the 340's that Lonnie's performance and FIC sell have worked well in e85 setups. Not sure if it's just the socks that come on these pumps that makes the difference or what, but I'm
Looking to ditch my dual 255's and go dual 340's. Are the 450's the same physical size as the 255's and do people run dual?

If you mount the 4303 correctly it is anything but loud. I have also heard cars with them solid mounted and the cabin noise is horrible

Mount the pump on a true rubber isolator, not just a pad

my exhaust is stock quiet and at idle the 4303 is hardly louder than a 255 in tank was

whoops, just saw this.

I only notice mine on start up....after that it's canceled out.

I just upgraded to Lonnies dual 340s and FICs 127s. Seem to be working fine. Lonnie does change up the wiring and socks I believe.

I am going to run an areomotive belt drive with stock rear tank and 2 gallon surge tank up front.

I ran the protuner 750 with some rubber under the mount first Noise was unbearable! Then with isolators as pictured above. Cut out more than half the noise. Still obnoxious IMO. Pretty soft isolators too...








You can see how soft they are in the Video.





The multiple inline walbro 255's I ran where VERY quiet in comparison. Only slightly louder than the OEM pump.

magna---pro-EFI, you need to move a LOT of fuel with E85

4303 is the way to go up to 1000w on E.

I just bought a Weldon 2311, supports 3200 hp gas, 1600 methanol, so e85 should be aroun 1800-2000 hp I'm guessing

What about a pump to go 1200hp on E85?

lonnies sells a true 340 pump. its not a the aeromotive one. her pretty much hates those. he also uses ssb lines in side the sending unit. its a 680lph setup, and made specifically for e85 so how can you go wrong.

Yeah I was looking at lonnies, already talked to him about what pumps are available. I want my car to be able to support ~800whp on E85 so I think the 340's are where I need to be at minimum. I'm just waiting till I get back from this deployment to get them. AEM has a new 340 pump that supposed to be E85 compatible. SDparts had made a post about them a while ago.

Also as far as the 450's I believe they are bigger in size than the 225's. I was looking at doing just one one those instead.

I ran a 4303 on my Lexus in the spare tire well. I'll be runnin dual Walbro 400s (E85) on my next setup; reasons being:

Cheaper ($250 shipped for both pump)
Staged Pumps (not heating the fuel up as much, I ran a fuel cooler with the 4303)
Less complicated (I'll run the pumps in tank, with the Lexus I sumped the tank and ran a pre-filter)
