Walbro Fuel Pumps - Everything You Need to Know for 500+whp

[@maperformance]

Drop a comment for fuel pump daddy! 💦

[@christopherrogers8316]

im getting a 255 for my boosted ep3, do i need to buy it with the install kit?

[@kedaotuning]

walbro 450 600+hp on e85 whit relay i replaced it every year just to be on the safe size im also going all motor on my street car whit VP M5 race map whit a external FPR cant wait to see the numbers. been using walbro for years K.I.S.S.

[@joshreynolds729]

So why is it called the hellcat is this what the hellcats come with for a pump in aftermarket translation? The reason I ask is I have a 16 hellcat challenger and as of now I dont need any crazy fuel pressure it's mostly stock on pump I just need a plug and play type kit that can be used for daily on pump and later on e85 and support 800 850hp just dont want this thing fucking up lines and other crap because its giving to much pressure. Also if I do this does it need a tune or will it except the old computer data and run fine after install. Pumps going out. Also if you have a pump that works was thinking the 525 but if you have reasons not to get it or if it needs special fittings please let me know.

I have the fore triple billet pumps for a 03-04 cobra and has 3 255 walbro pumps and I want to be able to run e85 with 1000 hp can I use 3 Walbro F90000267 to do that, its 3 6an lines into a single 8an line to the fuel rails

[@castielangelofthelord1992]

@@maperformance So I know this may sound stupid, but I just get anxiety around stuff like this because it costs money. I was moving my car parts for my upgrade into storage since I wont be upgrading for around 6 months, and I dropped my Walbro 255 fuel pump from about 2 meters high. It was in a box but no padding etc, and I am scared I have damaged it. It looks fine but some research shows that dropping them can cause them to become inoperable. Worried I am going to have to buy a new one.

[@vic_gst7579]

Great video! I currently have the 450 high pressure with a stm hard wire kit on my DSM. And made 480 hp. Currently trying to decide if I should upgrade to the 525 or just do a in line pump to compensate. Since I ran out of injector on the dyno the new 2150cc injectors will be going in. Pump gas car currently, might go e85 🤷🏽‍♂️

You'll get better hp n tq with the e85 just a less common fuel.. I have a switch for my ECU to switch between tunes e85 n 91

PWM Pulse width modulation makes the most sense to ,me.. I am looking to do an LS swap into a car that had a carburetor and 6 psi pump

[@alane8673]

Iv'e had two walbro 460's fail in two years...dont know why...but i'm over it.

[@2seep]

Most likely because of restriction. When you put the pump in a very small space it takes a lot to get the fuel into itself. So to do this is ramps up the speed to achieve the same intake of gas it usually does which causes it to over spin. Increased wear then failure is likely.

[@damnitdang]

Hellcat is 80psi+? Say, a 2jz is optimal forc35-45psi, so with a single hellcat, it won't ever be sufficient for its fuel rating?

Hey Leo, I have a 2020 Chevy Silverado 1500 no engine . Purchased a 427 self built ( don’t ask how much I’ve paid for it. It’s ridiculous ) short block Whipped LT. Anyway, I know you probably won’t get this message, but I’m looking for a fuel system for this truck. I can install two. Walboro 450, a Bean machine sump which I already have all the stuff for it. Flex fuel, methanol injection, Lingenfelter, Katech heads, Callies Magnum crank, Callies Compstar Rods. 1000hp+ daily driver. But anyway, how can you help me with fuel system like I said I have no intention on you replying to this, but I figured I’d write it anyway but I’m getting to that. I’m dropping my engine in right now..

It doesn't causes shortage by E85??As if when you actually spliced the power and also spliced ground in an intake with regular butt connector. Am nervous as doing regular butt connector and planning on use E85.Didnt use heat shrink either. Kinda nervous !
