That is flywheel correct. We will test on the chassis dyno as well when we get to that point.

What would be the benefit to going this route vs. port injection?

The current cheapest/most popular PI route looks like this.


THP port plates -$750-$850
THP Reflex - $1,200
AEM wideband for live feedback - $170
THP low profile lid for hood clearance - $1,200-$1,300
Injectors - $500
Fuel lines for port rails - $200(estimated)

Total - $4,020-$4,220

This doesn't include the additional labor to wire the controller or wideband, mount the controller, run the harness, install the port plates & injectors, and make the fuel lines. Or the added complexity of running and tuning a secondary controller.

Our pump and +30% injectors will require virtually no additional labor when doing a heads/cam job and will be competitively priced. It will be 100% controlled and tuned by the factory ECU with no added complexity.

Not to mention its been proven that DI makes more power than PI. As long as you can properly fuel it of course.

It won't be for everyone but it should cover what about 90% of people are trying to do with this platform.

If you are just clipping 130 degree pump angle up top at 1300hp with turbos what do you think the limits would be with a belt driven supercharger?

Really looking forward to getting our hands on one of these.

Question for you, What pressure are you running the 65% over injectors to meet that power level.

100hp less roughly. We will test it in a vehicle with a Magnuson 2650 as that's the most common power adder on this platform.

2,700psi max when using +65% injectors

We made over 1,300hp with turbos and full E85 on the engine dyno.

We made 1520hp on C16 with <100° pump angle when the inercoolers would no longer keep up.

LT4 injectors will operate at 3,600psi. We have been doing it for years. +30% injectors are stable to roughly 3,200psi and +65% are stable at 2,700psi.

Cost will be less than the LPE but do not expect it to be 50% less.

We're talking about XDI's injectors here, right?

I caught that too. Since XDI is the only ones making +65 injectors, I assumed as much. The FIC +30 will not handle 3200 psi, ever lol.

Correct. We currently exclusively use XDI for our DI injectors. They have proven to be the most reliable and best performing injector for us.

That is where I landed as well.

My OEM holds 2800 at 5.4ms on 30+. I'm surprised these differences would matter that much. And I do need more hpfp for race gas.

Race gas is much easier to do that with than E85…. Apples and oranges.

On E85 with stock cam fuel lobe?

No, race gas on 32% fl. Anxious to see how my new build does on OEM HPFP. I would buy this new pump if it was worth it.
