Our first 100% XDI manufactured and tested DI-Injectors are designed for the new GM LT series engines. With a 45% increase in flow over stock LT4 injectors, these supply the required fuel flow for high horsepower applications without the need for auxiliary fuel systems. These injectors are based on the original GM LT4 injector, which makes them a perfect drop in solution. Most of the ECU Injector characteristics stay the same.
Every Injector gets tested at 100bar and 200bar on OEM testing equipment at XDI. Every set gets flow matched to within ±0.5% at 100bar and 200bar fuel pressure !!!

Testing on several fully instrumented engines (8x O2, 8x EGT) done by Katech Inc. has shown unequaled results in terms of cylinder distribution, repeatability and stability at pressures up to 3000psi. Tuning changes required are minimal, offsets and current driver parameters stay the same. The injectors are E85 compatible and have so far been tested up to 1308bhp on engine dyno and 1067whp on roller dyno (Ignite E90).

Maximum Fuel Pressure is 220bar / 3200psi.

Straight E85, 1067whp GDI only !!!

no meth, no PFI, no extra ECUs, no wiring, full control, full OBD Diagnostics.

Sweet. But damn those are a pretty penny.

4 grand for 1000 hp? That’s a smokin deal!!!

[RDBill]

$4k is just for the injectors capable of making over 1000 HP

Yeah I get it, you still have other things to do, but as a fuel solution it’s 50% more flow than WX injectors for 25% more $$$.

How much does it cost to get a fuel system to 1000 hp with a +30% injector... you still need a secondary supplemental fuel kit, right?

I know these sound like total shill posts, but I have no relationship with Katech and no interest in modding my car, but it seems like a very compelling solution for those who do.

what high side pump will be able to keep up with these? the belt driven one?

What kind of FI (turbo, whipple, 2650)

Where were the injector at for instance,,, 6.X milisec? Did they have time to fuel or where they maxed out..

maxed out not meaning loss of rail pressure but as in enough time to complete the burn cycle..

[EDFHOBBIES]

I'd be willing to let my FIC 30% go for 2,000 to try these out I have about 600 miles on them now.

After I ported my 2650 I need bigger injectors now..

2k for the +30s! That’s a good deal. I’m sure that plenty of injector to get to 1000hp

On e85 alone no.. with meth or race fuel yes..
