E-85 tune...What injectors? - SRT Forums

**supermech21** · 11-24-2008, 02:57 PM

I havent really seen e-85 tackled with the SRT community....evo's are killing this shit. Im going to be running a fully built engine, ported head, 56lb turbo, tubular set up....what injectors should I run to support this?

Fuel set up RIGHT NOW : P werks BNF, walbro 255, 750cc RC inj, Boomba rail, -6an supply line, Return line, and Home made re wire. And obviously a ems to run it all.

I would assume something in the 1000cc range? I was going to add a full blown dual pump set up, -8an supply line and 1000cc inj. Will these support about 525hsp(mine should be in this ball park)? Will I need a special driver for these injectors?

Thank you

that's about right!!!

After reading the set ups on some of these evos im thinking 1200cc inj more than likely

you'll need between 30-40% more then pump gas. So it's up to you.

i run one hundred percent E-85 on my srt for the past year or so i went with the -8an line and fuel rail with 1000cc injectors with resistor box. under boost with a one to one regulator is great, under no load i am still trying to work out the kinks with my tune. good luck. this is with a holset

I've been running e-85 for 3 months or so and I run 900cc injectors with my 47lb a min turbo and haven't run out of injector yet at 25psi at redline. with a 56lb turbo i would probably err on the side of big. you have to go with a resistor box regardless. 1200cc's sound about right. what would you run for a fuel pump? need lots more at wot. you could probably get away with using a walbro 255 hp in tank with a bosch motorsports 044 pump inline. or buy the full blown dual fuel pump setup.

You could probably get by with 1000cc's and dual pumps, but if you're going to have EMS to tune it, might as well go with a set of 1200's to be safe. I personally run 1200's on my Evo, but I'm running the stock FPR which is around 38psi base pressure.

went with the 1000cc's and resistor box. Got a stupid cheap price on them so ill run them until the turbo runs out of steam or else the inj...i dont mind losing 10-20 peak hsp for the money savings.
