Whos got a hybrid??
vRSAlex:
Stock K04 injectors will run to 400 bhp ok as seen on quite a few revo race maps.
I'm currently running a hybrid. Hits 1.8 bar peak all day long tailing off to 1.5 at 7250. Drives just how I wanted it to. Boost comes in smoothly to help with spin.
I'm just using the revo race file with hybrid. Not aware of a specific 2+ file for a hybrid.
Fitted a few of the usp intank kits with the fake chinese walbro pumps. The whole kits looks like it was made at a nursery.
So is the rs3 intank pump better than the stock fsi pump Steve? Don't want to use the usp tat. Would prefer to use a Bosch 044 in the custom baskets I've made before on race cars, but its not ideal on a road car.

Have you still not been on a Dyno yet Alex?
What boost would a std K04 hold at 7000rpm?

Around 1.3 - 1.4 bar. Need to remember that it might not seem like the hybrid holds much more boost, bit the comp wheel flows more air too at the same boost levels.
Still not been on the dyno. Just need to get over to APR when I have a spare evening.

We don't use anything USP Ive never seen anything from them so can't comment, we order the pumps in direct from the US and mod the cradle to suite, flows 50% more than stock at the same voltage / amps when we tested ourselves
only just fitted the RS3 pump on Saturday so got loads of testing to do were using the twin pick up pipes too
In late 2009 when we first used the TD hybrids we immediatly noticed the mid range was lacking and coming in later.
We had two Ed 30 demo's back then and the stock turbo car we ran physically out paced the hybrid car so the way we had to tune the car to compensate maxed out the stock injectors & in my opinion left very little room for any kind of safety intervention from the ECU, if your maxing the fueling already then factory safety is out the window, our car felt much more settled with better fueling, I ran 2.2 bar holding 1.5 to 6600rpms at International 2010 with a GIAC race file and stayed with Hurdy right to 140mph when he ran WON nitrous (beat all his times too if you ask him, He ran 450hp & 510ftlbs on a DD roller set with the WON kit) so our car was fast back then 12.7 @ Inters sh*te surface in a fully built car two up hasn't been beaten yet even by the stripped out cars running just one seat & no trim
The problem were now having with the loba compared to anything else I've tested is the high torque at high RPM still got 414ft lbs @ 6400 rpms (the old hybrid tailed off like a bitch 300ftlbs at those revs, did peak at 420 with the meth though)
What duty cycle are you seeing in the mid with the S3 injectors AL ? Or are you on a tsi motor I think anything much above 7ms is too much myself although I've seen data logs up to 8.8 / 9.0 on some cars that run ok ish
I always felt the 390-400 hp cars were on the raggy edge of the fueling the data logs are so much more relaxed with more in reserve, I suppose everyone sets things up differently you'll have your ways we have ours etc
Kev @ Revo sent me the RS4 2+ injector file for my T box ecu, it's a custom flash I've not tried yet, by the way AL they are testing with the Loba now themselves on an R so Revo will offer software to support Loba
vRSAlex:
You have to try an 044 at some point. Won't work with the stock pump ecu but on a 3076 it was still holding 6.5 bar at 7.5k.
Is the walbro working ok with the stock pump ecu and can it run the tank down to empty ok?
Need to check my logs on the injector duty. Can't remember off my head. Apr fuel pump deffo helps ove the autotech imo. They always seem to sustain slightly higher pressures. Mine is an fsi.
Do you have an true egt sensor and gauge on your car Steve? I still find it amazing that the tiny k04 hotside will flow 500 bhp without getting too hot, even with the top part of the runners being opened out.
You say twin pickup, do you mean you are running the suction jet pickup that keeps the basket filled?
