I have a shop in texas telling me I should wait for this instead of going PI with my 6870. he said it would be healthier for the car instead of using PI as a bandaid.

This just feels like a bum deal. To deliver the full performance, this solution needs new GDI injectors, new cams, and the pump. You're already in for well over $5K and it's still less performance headroom than PI. You're also not really plopping down the stated performance without an upgraded manifold intercooler, so add that to the cost of the pump too. See the problem?

Literally every fuel-limited DI platform goes to PI for a reason: because burning money on the DI system is a waste.

PI is healthier for the car and it’s already a proven solution.

Gen 3 B58 adding PI is literally proof of that

Exactly! And don't forget they also state you need to upgrade the lpfp too before using their hpfp..

Feel like I'd rather just get an upgraded manifold / cooler with integrated port for the $$ .. wash the valves while we're at it

im curious to see how it goes. If it can make 600-700 whp with just the HPFP and turbo, seems like a reasonable alternative. Looks like there's some dyno tesing coming out... Time will tell I guess.

Having the TU pump on my 2021 Supra, is it even worth to upgrade if I’m going port injection? Currently waiting on the csf manifold but already have the reflex, 1050x injectors, and LPFP.

The DI injectors max out at about the same level as the HPFP, upgrading the HPFP alone won’t really do anything.

They have upgraded injectors available. They just posted 7xx whp with upgraded HPFP and injectors.

Great alternative to the complexity of PI for people that aren’t going crazy power, basically 95% of us.

Following. This is very interesting but time will tell. I’m ok with a little overkill but this could be a game changer. A game changer if it works and holds up and a game changer if it doesn’t and costs you an engine.

I’m curious to see more dyno results. Their test car makes 650 on the hpfp with stock low pressure pump and stock injectors

It's impressive what dyno results they are making right now with just the HP FP. If it's making 650 with just the HP FP, that's about 100 horsepower over the stock setup limits. Only cars I've seen get past that are using meth injection or some supplemental fueling being added.

 

[Thraxbert]

It's actually about 50HP. The stock fuel system can take you to about 600 WHP. It's the stock turbo that gives up earlier.
