Because NOTHING is being Made in the USA anymore!!

The revised OEM pumps have the same steel vanes now, and the failures were related to <2019 model LT4/LT1s... Many shops/part suppliers like Texas Speed, GPI, BTR & LME all sell the new updated pumps for less than $200.

Just an option as mine has 32K miles of abuse and it keeps the pressure perfect. Also note the new pumps do not get you more flow because flow is a function of restriction and said restriction is monitored as pressure which is controlled by the ECU tuning. SO... in Fact, you can add the TRUCK pump ($105 on Amazon with billet steel parts) which has a higher pressure/flow rating. You can then tune it in the ECU to meet the parameters of your car meaning it will work less or raise the pressure to meet the needs of increasing the volume of the system, like I have to 12.5 quarts. Hmmmm... Might have to try this.

Lot of misinformation here.

Our KAT-A7502 LT wet sump oil pump starts as an OEM GM pump purchased directly from our local dealer network. The "pretty cover" is a stock steel cover with a coating for dress up purposes only. Not an aluminum piece. The blue covers are a staple that helps identify Katech oil pumps from others. The factory 2020+ pumps while revised in design still use a powdered metal inner ring which is the failure point in all Gen-V LT oil pumps. GM has produced no LT wet sump oil pumps that use a billet steel ring like the Katech.

If you would like to be further educated on our oil pumps compared to the OEM feel free to give me a call. 586-791-4120 ect 222.

I can assure you no one in the world has done more development or simply even had more Gen-V LT oil pumps apart than Katech.

Not to jump on, but he also has misinformation about the differences between ZL1s and ZLE in his videos...

And where can we TUNE the oil pressure? Is that in EFILive or a product outside of HPTuners? Kind of like the claims of independent cylinder spark tuning in another thread.

Thank you, as always, for the clarification on the product you produce for our Community. The expert on his product has spoken.

Tuning for oil pressure is not possible within the current software parameters of our cars brotha. Oil pressure is driven mechanically via the crankshaft and the solenoid attached to the oil pump allows the variability from low to high pressure when you gun it.

As for tuning cylinder spark independently.... That's not a thing either. Unless there are parameters I don't know about or they are in user defined parameters that you need to interpret yourself. I would love to be wrong here, but I've been up and down all of the available features in HPT and have never seen that in the spark section.

As for the Katech oil pump itself. It's been one of the best designed aftermarket pieces that I have ever run in any vehicle. A big thank you to yourself and the guys over there at Katech Mike for making some badass products.

Katech Mike, thanks for jumping in for clarification.... that is super helpful!
As far as "tuning" for oil pressure looks like we have some NEW tables from HPT.

The OEM pump / tune doesn't go from low to high pressure mode until 5,750rpm. Looks like you can now adjust the RPM that the pump goes into high pressure mode, or.... adjust the RPM vs. Torque table to kick in at a certain torque value. Full disclosure, this is coming from a members only JWT video (not my own experience)

On high HP PD cars, he is now triggering high pressure mode down at peak torque where you need oil pressure the most. (triggering around 2,500rpm and using the inverse table to turn it off when you want) which should help save some bottom ends... ?

The new table is located.... VCM Editor - System - Variable Oil Pump Control

Hope this helps
Interested to see how everyone decides to use it.

[radz28]

Regardless - THANKS, Gabe, for clarifying the new definitions! That sounds cool!

I'll have to take a look at that, as I think I may be running previous versions of VCM suite and have never seen that before so it's nice to see they are still updating and adding things on there for us!

[radz28]

Yeah - they added some more TB control a month or two ago, and shifted some table row values around (e.g. the AIRMASS axis for [17071]). I haven't noticed much more, but I haven't been looking much.

Really??? Your OWN website says directly that you can TUNE for various pump volume/pressure delivery. FIVE YEARS AGO!!! Shocker!! Not just some recent update if you know how to actually program an ECU code.



Hey Mike... How long have you been with Katech? Back when Katech was family owned and run and when the engines were the standard in Grand-Am LMP racing, I worked directly with the owners and Jason to host the events at Autobahn and the great parties hosted there by Mike Newlander.

I guess more people need to look deeper into the tuning of cars instead of just using bandaid modifiers to fix symptoms.

LMK cause last I checked, at least I am racing my car and several others with my parts in sanctioned events to find out what actually works using my own money, car and parts to prove what is only hype, speculation and junk vs what works. So a video I have from over a year ago will be outdated to what is new now. Only difference is that I am no longer sharing all the details so others who have never had their car on a dyno or track can monetize the testing and parts I have spent two years developing. This is why when I do share something, I back it up with the theory of why so an educated person can find the facts.

Wow. Blocking this guy. Completely off the rails at this point. What a d!ck. And this guy is a vendor? Not getting my money.

Why? When I question from doing research? When their pump is out of stock and the OEM pump has been working fine for 32k miles in my car? The only way to establish what works is by research and testing. Obviously the majority of people here are into drag racing, which in most venues setup is completely different. This is why I always ask the questions of the goals. The OP here wanted an alternative and I offered insight that was immediately discredited without any true facts to back up the insinuations.

In some of your videos. Here. The more you post, the more you reveal. You, still, have yet to show where this spark adder by cylinder is. That would be interesting to learn, for one. I make mistakes, and own up to them.

You have the potential to alienate more than you are attracting.

So it seems you want me to show you how the sausage is made and how to season it. Dwell timing adjustment and logging is nothing new... I adjust dwell timing to determine lots of issues to create better cylinder balance, plug heat range and/or gap as well as using inductive tools to see a graph of all cylinders. True tuning is not just looking at what the OEM median sensor quality PIDs are giving you.

If my not telling you HOW I can tune, make power and have greater reliability than say a competitor, I'm sorry you feel that way. It is why I can justify charging for the services we do and the exclusivity of some of our contracts with racing teams & manufacturers. Some of my customers here have witnessed such firsthand, because they are my customers.

[radz28]

Your video showed you took you car to be tuned elsewhere. If that's the case, YOU didn't tune anything. The way you state, almost EVERYTHING, you make sound like you've advanced, in the couple years you've been working on this platform like you have innovated more than guys that have been on it for a decade. You can't even get facts between differences of models right, let alone dyno numbers no one's ever seen, and you talk like you know more than the likes of Steck, Tanner, Bosson, Ghuggins, and our more local experts, like King' and Megahurtz (he's over on HPT, too, sharing more than some of those already listed). You expect to be trusted among the likes of these experts? You don't get simple facts right, but we're supposed to believe you?

OK. I guess.

BTW - I didn't ask for specifics, nor do I think I'm entitled to anything from anyone. Additionally - I don't expect anyone to believe anything I say, but I try to post facts or data to support my statements. You, apparently, believe otherwise. I think everyone can an will come to whatever conclusion they will, but I'll call out inaccuracies for the greater good of this Community, because I, literally, gain nothing. I am 100% volunteer and support all of those who contribute positively to keeping this place healthy. I have nothing to pedal or push, and have no interests except to see the love of this car live on.

EDIT: I gain knowledge and friends
