PS2: I have Audi A4 B8 flex fuel injector bosch number 0261500164 they are good up to 375 hp under E85 according to APR.
So should be good for 450hp at least with 98 gazoline ( 30% less fueling) so that is a cheap OEM option for those who don't have access to E85. Those are plug and play
My T6 make's 320 hp @ 5900rpm with oem turbo and E85 with those injector. At 5900 rpm ( max power) injection time is 7.150ms runing 180 bar of fuel pressure.
so a bit of space. I guess max would be to run a bit more than 8ms
Apr K04 with OEM A4 B8 flexfuel injector's.
The other option for this engine is the Opel LDK injector's delivering 30% more than OEM injector's. Bosch 0261500112. those need different connection so some work on injector wire harness
This guy did 550 hp on EA888 Gen2 engine with those Opel injector's. But still not enough fueling for E85.
with your turbo running E85 I would need injector that can deliver enough fuel for 160 hp per cylinder with 98 gazoline. That is some big injector's about 55% more than OEM. Only Nostrum can match that from what I know. they flow 100% more than OEM.
But open to other sugestion's
