N55 Injector Flow Rates

What are the flow rates for the OEM N55 injectors & the HP levels they can support (taking the HPFP out of consideration)? Thanks.

I don't think anyone has hit the limit of N55 injectors. Most are supplementing with port injection long before hitting any injector limits. N54 injectors are theorized to be able to support ~3000whp. N55 injectors should have similar capacity. They just use a different injection style but the overall dimensions and capacity of the pencil style injector itself are similar.

A dual HPFP setup appears to still be limited to around 700whp, or at least that's all that TTFS rates their N55 $5,000 dual HPFP setup for (620whp): http://tuningtechfs.com/ttfs-n55-dua...ctory-upgrade/

VTT has their dual shotgun that supports 700whp+ on 100% E85: http://performance.vargasturbo.com/e...&product_id=44

That would lead me to believe injectors shouldn't even be thought about until 1000whp+

Try taking a look at S55 development to see what limits they have hit there. S55 shares injectors with the N55 and people on the S55 platform are pusher higher on DI only setups than anyone I have SEEN do on the N55 platform. There is more money in the M2 community to push $5000 fuel pump upgrades lol.

Does the upgraded pump require tuning in open & closed loop?
