Are these the same 040 injector?

I could be wrong but I think racefuels is supplying the V8's E85 this season and it's being branded as Shell stuff. Not that it will probably ever happen but it would be nice to see it rolled out at Shell servos and maybe create a bit of competition

What fuel are you running? 30psi i would expect to see more hp than that
United E85. Its auto with a big stally so it will always read lower on a dyno by at least 10% compared to a manual. It made 376kw on 26psi which is why I asked about the exhaust restriction. Lots of air going in and not enough getting out
Definately worth investigating if I can replumb the gate in its current location
-
Interested to see what difference venting the gate to atmosphere would make with my set up. Currently running a 4" dump to the bellhousing and then 3" from there through a single round muffler after the diff. Single cam RB30 with a powerglide. Head is stock besides slightly oversize valves and a small 218 @ .050 wade cam. Making 396rwkw with a 1.06 gtx35 on 30psi. Basically stopped making decent gains in power with more boost and inlet temps rising quite fast. The gate plumbs back in maybe halfway down the dump pipe. Would it be much more efficient going to atmosphere as I presume a fair amount exhaust flow would be through the turbo at that boost level?
I didn't have a chance to dump the exhaust last time on the dyno to see if any gains were to be made but I guess the stock ports in the head would be holding things back a little also?

Running 4bar fuel pressure so a single 460 will most likely be on it's limit by the sounds of it. I was considering setting up a fuel pressure sensor anyway so I could always set that up alongside the current afr engine protection. The pumps also have check valves installed down the line so if one fails there will still be pressure.
I'm still not sold on the proflow pumps as they are probably just like a ebay knockoff 044. Might be worth modifying the hanger if necessary to fit a pair of 460's
Has anyone got any feedback on the Holley dominator pumps? This is also another option if I wanted to retain my current surge tank
-
I could always run a single 460 as that will fit the carrier. Currently I'm running 1 x 044 constantly and the other is staged to come on at 10psi. Car is on E85 making close to 400rwkw through an auto. What sort of power is a 460 rated to?
-
-
Looking at replacing my current 2 x 044's with a proflow surge tank that incorporates internal pumps. It comes as a kit with these which I presume are just a rebranded walbro style pump as the aem, aeroflow, etc pumps all look identical. Would ideally like to run 2 x walbro 460's but I'm not sure they will fit the hanger in the tank. Any feedback on the proflow pumps would be great
-
I presume this style gm sensor is also compatible? It looks to output 50-150hz like the other continental sensor and is a little more compact in size
-
No one using these at all?
-
Just after some feedback on the Bosch 0280158040 980cc/1150cc injectors. How do they compare to the Bosch 1000cc item? Looking at doing an upgrade to suit E85 in a RB30 making 350-400rwkw. Haven't managed to find much information on them anywhere
-
Would anyone happen to have the dead times for Siemens 750cc's? The part numbers are FI11445 3145. They are probably dinosaur spec now which is why I haven't been able to find any information
-
Using 3 slots on my home made set up with a PS2000 and GT101 sensor. No issues that we have come across so far
-
With a Haltec platinum pro would it be possible to switch between 1 map with certain boost and timing settings and another map with higher boost/more timing that also activates water/meth? So you wouldn't have to constantly be using up water/meth and running the higher power map
My HFS3 is hooked up to the map switch input in my PS2000. Mine is the same as what JGB1600 has done, the failsafes will switch to the conservative safe map plus turning the system off at the gauge will also revert to this map
JGB1600 did you find any difference between the HFS3 and 4 or just the extra features?
-
you have a gtx3540?
I did a vl with a 3540 1.06 internal gay..t
we ran 30psi and 20 degrees of timing on pump 98 and 450cc of water/methanol 50/50 mix
raced it for a year like that. Went 10.4 @134 mph s.. manual.
Only took it of to upgrade to precision 6466 turbo and did e85 as i took my water inj setup back of it
cheers

Pretty impressive results there.
Yeah mine's a GTX35 with 1.06 T4 rear. Made 290rwkw with 17psi and 17deg on straight 98 through the powerglide. Once its actually got some boost in it then it should wake up a bit.
-
Pretty keen to see the gains in mine on high boost setting. Alternator shit itself when we went to do the water/meth tune. Even an extra 5deg should make a huge difference
-
Theres plenty of failsafes you can put in place. My aquamist kit has low level, low flow and over flow which is set up to trigger a map switch in the ecu. Also got engine protection in the ecu as a extra safety net. I honestly can't see it being anymore risky than having a pump or injector fail with a tune on straight fuel
What sort of extra timing on average has everyone managed to add?
-
My alt to battery wiring is brand new as I've just put a new engine harness in the car. Used 16mm welding cable which should be heaps I'd imagine. Is the size of the sense wire critical? I might pull the engine to chassis earth strap off and clean the connections again just to eliminate that.
Also what sort of amps would be sufficient for my set up? Something around the 90 mark would be heaps I'd imagine or am I bettter off upgrading to a 105-110amp unit?
-
Having voltage issues with my alternator and was looking at maybe doing an upgrade if it was necessary. What sort of amps would be sufficient for my set up. Car is a VL turbo running 2 x 044 pumps (1 is staged to come on at 10psi) , 6 x LS2 coils, 750cc low impedence injectors, Haltech ps2000, no thermo fans, basic stereo with no amps and battery in the boot. Currently have a RB25 alternator in the car which is 80 amps but my be failing higher up in the rpm as you can see in the data log below. Ramped up fine on 17psi but had a smaller drop in voltage, 22psi it broke down under boost.
-
That inlet manifold would put a horn on a jellyfish
-
yup stay away from the metal heat sink ones if possible i had a few come in from other places with detonation issues and it was because they were tuned with too much dwell.... its a documented fact they have cost guys engines.
we always recommend running the;
C1512
D514A
OEM part 12573190
and are able to run low dwell and up to 1.5mm gaps with boost.
If you do choose to run with the inferior truck ones just make sure you keep the dwell in check.
Just wondering what you usually dwell these coils at?
-
Does that apply to the truck coils only or the car type ls1/2 items as well?
-
Just about to look into doing this on my car. I presume this sensor will work fine?
-
I was thinking the exact same thing. I've seen one with a set of 440's in it and a factory rb20 ecu and that only just ran
EV14 0280 158 040 settings needed plz .

Same as what I have in my rb30. Running them at 4bar base but can't confirm if the raceworks data is 100% correct
