Here is my setup
84mm AEBS sleeves
T6766
Front facing Manifold
Dual 255 Walbros
Skunk2 Pro 1's cams
Hondata S300

With my 1000cc injectors @ 20 PSI with pump gas I'm 85% at 8000 and 90% injectors duty at 9000RPM? is it normal?

Do I need to upgrade?

I except to go 30PSI with C16

What is your base fuel pressure?

sanman000719

yah what is your base man i have personally made 650 on rc1000's at 85psi of base not ideal but it worked for 2 years.

and i would do the corn over c16 but thats just me

No corn water where he is, as he is in France. Check base line fuel pressure, and check to make sure fuel pump, lines and voltage are stable.

sanman000719

oh oops correct lol

Steeve_Civic

I ll re Check, but it is around 50 PSI
Do the corn lol!! We can get some E85 fuel, but I prefer racing fuel

If you are injector limited you can try running less rpm, more boost. You will find rpm eats up injector quicker and your peak HP isnt at 9000rpm anyways.

You can also extend your injectors slightly by increasing the fuel pressure - assuming you have enough pump left.

e85 is racing fuel i know news travels slow but ya'll over seas have to know this by now

E85 is ethanol-based fuel that is more forgiving to the environment that just happens to have knock-resistant qualities due to its alcohol content. It's not "race fuel".. Younger people in the U.S. just tend to treat it as such.

Ok but with my 6766 Turbo I need to run high RPM, but you are right around 7500 RPM duty cycle is 65% @ 20psi.

I can switch for ID2000 or slightly less that is not a problem, the question was how many HP can I hit max with my ID1000?

Now there's an ignorant entry to your educational postings. Come on now.

The car wont run worth a **** with 2000's on gasoline. I tried before i fully switched to E85. Im sure with a LOT of tweeking i could have got it to run better but wasnt ideal at all. 20 psi with a 67MM has got to be a pretty decent amount of power. What fuel pump are you running? what regulator are you running. Give a complete rundown of the fuel system right down to the lines and wiring for the pump.

thats what i was thinking also, but thought i would leave it alone lol

Steeve_Civic

Pump fuel here is around 98 oct
Fuel pumps are 2 brand new walbro 255 with AN 10 feed
Fuel pressure regulator is AEM
Wiring is a 4mm from box fuse

I don t like E85 because it is not the fuel in winter and summer, even between two differents fuel station.

Steeve_Civic

I m going to increase fuel pressure to 60 psi first

are they high pressure 255's or standard 255's . Nice 98 octane should be able to make some really nice power with that. I would increase base pressure and see where that gets you.

Steeve_Civic

Gs342 Walbro I think they are standard.
What is the part number of the high pressure?

98 is RON pump fuel I don t know you get same fuel? I think it is your 93 oct fuel

GSS342 is high pressure, GS342 is standard. Be careful running up the base pressure with those pumps. They fall on their face after 70 psi.

ralph11sec

what fuel pressure regulator are you running? rising rate right?

if you set it at 50-60, in my experience a single walbro setup with id1000, the fuel pressure falls off at high rpm...supposedly you should be hitting 80ish psi @ that boost levels, but if you record your FP, it will not go there.

id1000 on pump, 500 should be a cakewalk.

Dont know if this has been mentioned already, but i dont think you can run dual fuel pumps on the stock wiring harness, assuming it hasnt been upgraded already.

Steeve_Civic

I learn every morning on HT thank you !
I m running 50 Psi base fuel pressure with AEM FRP and running 20 PSI so I m around the limit of the dual 255 walbro?
I heard people hitting 800 HP with dual 255?

Spawne32

iTrader: (3)

dual 255 high pressures, ive never seen anyone actually try to push a 255 standard that hard.

ralph11sec

aem fpr is not a rising rate.
that is your problem.

get an electronic fpgauge and monitor your fp @ high rpms...

Turbo-LS

iTrader: (4)

aem is a 1:1 regulator, i dont care for them but they are rising rate. Both pumps should ahve their own dedicated 10 gauge wiring and 30amp relay.

Steeve_Civic

AEM FRP see the boost pressure and adjust it.
I have only 1 wire for 2pumps one 70A fuse and one 60 relay, do you think it can affect the voltage? I can check that that point?
