PSI086

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

Are these the same 040 injector? http://www.raceworks.com.au/fuel/injectors/bosch-1150cc-4-bar-3-4-length-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

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

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?
