i'm going to be making the switch from 93 octane to some sort of race gas and i'm curious what fuel pumps you are running. i currently have a walbro 255 HP pump and i wasn't sure if it could handle the increased fuel usage when i up the boost. currently running 16psi on an sc61.

 

bump?

 

I use E85

 

i'm looking for fuel pumps

 

Made 607@34 psi on a single 255 on C16 leaning on top. Installing a 400 as we speak.

 

thx for the info. i should be in the low 600s so i'll prolly do the same then.

 

Dual walbro 255s here. -8 feed, -6 return, E85.

 

Dual walbro 255's

 

yeah i can get e85 here, but would rather go with race gas since the e85 ethanol levels vary from time of the year and i really don't want to constantly adjust the tune to make up the differences. plus i only drive the car maybe once a month as it is so the extra money on gas isn't really that noticeable.

 

Single walbro 255 in my setup and ran 112 octane at 26psi

 

Get a 400 in-tank and be done with it. The dual walbro setup isnt cheap. You could also run a walbro intank and a bosch 044 inline. A single wabro will make 600 but thats pushing it.

 

any places cheaper than extremepsi on the 400s?

 

the pumps are only 159 bucks, how much cheaper do you want for a good fuel pump? If your shooting for 600+ whp 159 bucks doesnt break the bank lol

 

well they're $150 at extremepsi, was just curious if anywhere sold them cheaper. i just spent $550 on aem gauges so if i can save $10 somehow, i'll do it hah.

 

^spending money in the wrong places.
I realized over time that the only gauge I needed was a wideband everything else is on my tuning software.

 

well one of the gauges i bought is wideband. right now there's an autometer egt gauge that doesn't work so that needed to go. and since i'm a bit ocd the fuel pressure/boost gauges needed to match the wideband.

 

The more you know the better. What tuning software do you have that you can monitor things in real time? Do you have that Brian Spilner setup?

 

I have ectune demon setup. I can monitor my fuel pressure, oil pressure, boost, vacuum, wideband etc etc. aka the Brian spilner setup

 

Nice, I've been going back and forth on how I'm going to monitor things so nothing blows up and I don't want to give 10 million gauges to thieves so I'm thinking about something like Tunerview but I dunno, Stack is a bit too baller for me.

 

I have a tuner view. Best investment can monitor everything

 

aeromotive eliminator fp is what im running no problems what so ever

 

Dual Bosch 044s on q16

 

^This. Simple & cost effective for your Hp goals.

 

Single Deatschwerks 300 lph on q16

 

ok, i ending up buying a walbro 400lph.

now that that's set, what injectors are you guys using to get into the 650hp range? right now i've got a set of 1000cc precisions and was looking at changing to the 1100cc fic hi-z injectors. main reason for the change is that we've had some issues with the precision injectors not being consistent.
