fuel rail question

feeds@yuku.com (xxturbo) — Sat, 30 May 2009 12:32:00 GMT

gary, i'm wondering how to tell if a fuel rail is too small.
my blackbird turbo has 450cc injectors with a 0 map at idle, but it is about +25 at 15lbs boost. fuel pressure is about 75psi at boost and about 30 at idle.
it seems that with these injectors, fuel pressure should be much lower than that, to support just under 300 hp. what ya think?
thanx,pat

FUEL pressure??

feeds@yuku.com (SBeachill) — Tue, 21 Apr 2009 11:05:04 GMT

Have had conflicting info on this, I'm running a BEGi FMU on my GSX14 Turbo and some people have said set the base fuel pressure at 43psi and others have said a lower figure?? Any clarification on this? manual says 43 psi on fuel pressure but would take that as what the stock regulator would be set for (am I right?)

Cheers

HELP!! FMU problem!!

feeds@yuku.com (SBeachill) — Thu, 02 Apr 2009 04:56:45 GMT

I appear to be having a problem with my Begi FMU, my bike will run and idle fine without the FMU in place but when the FMU is hooked up the bike cuts out and refuses to fire up?? have I hooked it up right?, I have a line from the end of the fuel rail going to the IN line on the FMU and then the line on the other side of the FMU returning to the fuel tank, a vacuum line from the inlet manifold to the feed line and the needle valve venting to atmosphere, have tried onset screw in a lot of...

I had several issues since the first time I meet with installing...

Just wondering what fuel pressure I need for 8psi boost on ZX-14?

feeds@yuku.com (TurboLover) — Mon, 09 Mar 2009 19:12:52 GMT

I have a stage one Cycle-Logic kit on my stock flies out ZX-14. It will be running 8lbs of boost. It has a Walbro in-tank pump in place of the in-tank stock pump, and its running a Cycle-Logic custom rrfpr. I was just curious what fuel pressures I should see under full boost and at idle. I'm in the process of installing the kit now, and have a prosport electronic fuel pressure gauge that goes up to 85psi. Will I need a higher reading gauge? And what would be good numbers fuel pressure...

Bigger injectors V's secondaries

feeds@yuku.com (ottocycle) — Tue, 20 Jan 2009 11:41:32 GMT

Hello again,
I am boosting a Busa engine for a car project as seen in my other posts and was thinking of using secondary injectors. I am encountering space issues and have taken another look at using bigger S2000 injectors and a PC3USB. I have checked posts and would like to start a thread on the pros and cons of each. Gary and "Smithabusa" I would love to hear from you on the topic. I have a GT2560R turbo, .080" gasket (8.5:1 compression), head studs, BEGI regulator,...

FMU, FPR?

feeds@yuku.com (SBeachill) — Thu, 15 Jan 2009 01:57:53 GMT

Would this work on the same principle as the BEGI/Cartech FMU?

Confused!! FMU, PC3, Multi hub etc etc

feeds@yuku.com (SBeachill) — Tue, 13 Jan 2009 14:10:36 GMT

Hi All

Currently Turbo'ing my GSX1400 and getting a little confused as to what I require! Have been told the stock pump is capable of coping with 200+ bhp will only be running 6-7 psi boost Max, I already have a PC3 but it's the pre USB type so I can't hook up the HUB can I still use the the PC3 I have and add an FMU to control the fuel or do I still need a map sensor aswell?? Where's the best place to get the FMU from? any reccomendations? What else will I need...

Secondary fuel injectors with Megasquirt.

feeds@yuku.com (ottocycle) — Thu, 01 Jan 2009 19:36:40 GMT

I am working on the final stage of my turbo build using the Garrett GT2560R turbo (aka as the GT28 though I don't know why) for my Busa engined car. I have a .080 base gasket, after market studs and intake sprocket and an intercooler. I will build a weld ell manifold and plan to keep thew stock Suzuki ECU and use an extra set of injectors in the plenum triggered by another MAP sensor to add more fuel under boost. A wide band O2 sensor will be added to closed loop monitor the whole setup...

I Bought Chris Reno's Busa

feeds@yuku.com (CopperTurbo) — Mon, 05 May 2008 12:33:20 GMT

Hi to all,

I recently found Chris's Busa on Craigslist. Took a ride over and I couldn't believe how clean he has managed to keep it all these years. Hopefully I'll be able to do the same!

A little about me. Started riding way back in 1964 on a used Honda Dream (couldn't afford a Super Hawk). After playing with a AA Funny car in 1971, I bought a new Kaw H2 750 2 stroke. I lived back east then, so in 1973 I took a few engine parts up to Kevin Cameron in...

Fuel needed for 6 psi

feeds@yuku.com (Kerry) — Fri, 18 Apr 2008 20:31:24 GMT

I am in the process of building 3 bikes and I have the same question for all three.

They will be stock compression and running about 6 - 7 psi
Can I get by with just a 1.1 ratio regulator and PC3 being that the boost will be this low? I will add a higher flowing fuel pump to them for sure.

And I also have two of the Vortech super FMUs and was wondering if it would be better to use a 1.1 or the super fmu and if I use the super fmu what ratio would be needed for this low of a...

dynojet hub and map sensor

feeds@yuku.com (denmah) — Mon, 09 Jul 2007 00:39:34 GMT

hi all, anyone using just the power commander and a dynojet hub with a GM map sensor to add fuel and no rising rate regulator?

i have a turbo project im going to start in the winter hoping to add only 40-60hp well within my fuel system limits, and i was going to simply install the dynojet hub and a gm 2bar map, and just add fueling in boost.

i know i read in some other posts people were using it... i was just wondering how you liked it? and if you would reccomend it?

Plotting injector shot volume against fuel pressure

feeds@yuku.com (emarsh) — Wed, 27 Jun 2007 21:42:00 GMT

I bet the relationship between the amount of volume an injector flows and fuel pressure is not a liner one. Is there a source of graphs available that chart this for common injectors (such as the S2k)?

On a bike w/ factory secondaries...

feeds@yuku.com (The Ahab) — Mon, 25 Jun 2007 00:29:17 GMT

like a GSXR1K or the new Busa, Is it possible to run a PC3USB w/ Hub (and a 3 bar map) to sufficiently fuel a Turbo? Would it be possible, or would the secondary system need to be upgraded as well (ie larger injectors, new regulator etc)?

With a new Busa w/ factory secondaries, there may be a upgrade path if a Busa can be purchased from a salvage yard (and we all unfortunately know this will be the case, thanks to squids) suppling the TB's, ECU and other upgraded parts.

Now it wont start????

feeds@yuku.com (Turb06le240) — Wed, 18 Apr 2007 03:37:59 GMT

This is getting aggrivating, I had it running, with the fuel lines and hose clamps, now I mounted everything and ran the aluminum fittings and -6 hose, and it wont run, it sarted and then eemed to stop and wouldnt restart, When I got it started it wouldnt idle or really take the gas, then when It of gas..
My fuel psi is 43psi with a 0 map at idle....tryed to restart it It smelt like gas in the dump pipe..
I checked for kinked lines, and all the obvious stuff already, any ideas..
Thanks

Vortech FMU w/ Mallory reg for turbo busa???

The bike is an 06 hayabusa stock motor
The turbo is a big 16G evoIII {6psi max}
Base psi 43 psi, 4 degrees of timing out under boost, .20 plug gap, and I will have it mapped..

I was going from the tank to the filter to the pump to the rail, from the other side of...

Location of 3Bar map sensor

feeds@yuku.com (Paula Shannigan) — Wed, 21 Feb 2007 12:43:22 GMT

Hi there on my 99 hayabusa setup I'm running a 3bar map sensor with the new power commander HUB I want to know where I need to plumb this in at the out let of the compressor in line with wastegate and the Fuel pressure regulator or behind the trottle valves?
Thanks for you help
