I don’t think I’ve seen anyone talking about this thing yet. Are there any details out there other than what’s on the website so far?

saw them talking about it at PRI in indy....supposed to the cats meow...iirc it takes care of the low side too....

[Nataphen]

The low side is handled by their new drop in dual pump setup. Just waiting on their PnP harness and filter to run that piece fully through the factory controls.

yup...youre correct....i mixed them up....

Wonder how its specs compare to LPE's BBFP?

There is already a thread with more info about this hpfp on the forced induction section.

Thank you. Subbed to that one.

Katech responded to me on Instagram. They basically expect it to flow more than the LPE BB. However, is that because its designed to run at higher pressures? People run the LPE at 2900 in LT4's. I want to know if the Katech will flow more at 2900 psi vs the LPE. I'm going to buy one and test it.

That’s the million dollar question.

Good to see Katech getting involved in these cars and the fueling limitations.

My hunch is that it's slightly better. If you go back to 2017 or so LPE made 1400hp on E85 with their fuel system on a turbo LTx. This was done on an engine dyno similar to Katechs testing. The problem is belt driven superchargers consume a lot of power to turn. A 2650 probably takes 100hp to spin at 18psi. So a couple ricer math equations later this pump is probably good for 1050whp on full E85 with +65 injectors and a 38% cam fuel lobe along with a good low side to feed the top end.

I think a lot of the big power guys have already went port injection and they aren’t coming back. Imo if this pump can provide a legit gain to the bolt on guys who want to take it a step further to run full e85 or stretch it further on E blend it will be a hit. Yes it would appeal to the guys with aftermarket cam also but I think the bolt on guys will be the biggest market

I agree. There are some people who don't want crazy street cars but they have the financial ability to pay for expensive parts to stay away from more complicated setups or meth.

My interest in the Katech is strictly if it can flow more than the LPE BB on the stock LT4 cam lobe at the same pressures. If it does then this will be a huge win for the stock cam bolt on guys that want to run full pump E. Then the next win will be for the real radical builds that are pushing the limits over 1200rwhp.

Yeah I also fall in that category. And like you I have been playing with bigger injectors and fuel pumps on bolt-on cars extensively for the last 4-5yrs. The problem I see with LT1 cars is the pump lobe is even smaller than the LT4. These high side pumps really need a bigger fuel lobe to get the most out of them. So it might make more sense if wanting to stay on the conservative side but NEED more fuel is to grab the BTR big fuel lobe(32%) stock profile cam. IF you can do the work yourself it would cost less than half of one of these big pumps and likely provide more fuel headroom vs a stock lobe cam with bigger pump. Or keep your LPE and do the BTR big fuel since you already have it.
