I have a 416 in my e-85 street car and I wanted to take full advantage of it so I also installed a 1/2" supply line and use the stock 5/16" vent line for the return.
Also, the pump hanger is a pro-type custom billet unit we made and are testing it which takes advantage of the larger lines.
Our preliminary testing shows it should be good to over 500 RWHP, and we may verify this Sunday at the dyno!
When we did the original conversion with stock lines and a 400 LPH pump, duty cycle was ~ 66% at 400+ HP.

Gasp, the stock lines handled that much fuel?
Nick, that's some good info. I was under the impression this was a drop in pump. Does the hanger need to be modified?
How far do you plan on pushing the pump? I would like to make in the neighborhood of 650 RWHP. According to the calculator this pump should support that but again I would like to hear from people that are actually using it.
Keep us posted on the data. Thanks!

My race car has about 650 RWHP with e-85 and I use an external FP.
At that level I would never depend an in-tank pump on a hanger to supply an adequate and reliable fuel source.

What's the reason for not trusting an intank pump to a certain HP level? Does that rule apply to double pumpers etc.?
I've run the DW301 pump mid 10's on E85 and it was able to keep up.. I'm sure this pump would run faster than mid 10's
I would beg to differ.. don't care if its a vendor or not ... 301 pump on E85 has been mid 10's on ALOT of cars.. on 80's ... I personally setup at least half dozen and they run mid 10's no issues.
Some vendors will put you into parts that they think you need.. I can tell you for sure .. a 301 will support mid 10's on E85 and be safe ...
The Walbro is a bigger pump.. so I don't see low 10's hi 9's as an issue...
If you really want to turn things up to block breaking levels ... use a twin intank pump ... run 9's all day on 2 301's
Byron is a downhill track
You can see them run at the Grove and a few in Kaukauna...
As an aside I've seen a 255 car trap over 130 at full weight
The problem is at that power level ... ALOT of other crap comes into the mix... @ mid 10's you can still drive them and not have to wrench all the time ... faster than that ... you start stacking the cards against you pretty quick...
everything starts to be questionable ... motor, trans, diff, chassis, fuel system and on and on ...
Even if you DETUNE and run hi 10's .. plenty fast in the street and a 301 or walbro 400 can hold that all day long and then some.
