While many experienced people here and I do agree with their comments. I must say meth is not as bad as the rep it has... a well put together meth kit still costs some coin. I have a 5 nozzle prometh setup with ran like 2.5-2.6K back then and Im able to run full E for 900hp... same setup net me 1100hp on my previous 416 build.

The bad rap is because people who "normally" use meth is they want to keep it under 500-600 bucks and its not well put together.

Think of it this way.... pumps are pumps... and the port injections, in tank pumps they are all aftermarket that can fail JUST like a meth pump... i understand the chemical component of meth is different but thats why you go to dedicated companies like pro-meth or alky, that that's what they do and provide you with the info and quality of parts you need.

A quality part is quality no matter if its used for meth, e85 or coolant. (in terms of pump use)

That being said if back then the options that are out now and at the price range they are at now, I would definitely have PI but THPSI was only doing his own thing back then and not where he's at now.

like everyone has said, first establish a goal and go from there. Hey, at least with Z's you guys have a great engine to start with... us SS guys besides the fueling we also have the immediate engine limitation... so it isn't that bad having to send 5K on fueling instead of 13K on a shortblock PLUS 5K in fueling and labor of it all :P

Oh and regarding port heads, the way i see it everyone ends up getting the head so just do it and not pay double labor....

like its been said here... cry once.... or like shops love to say... "Pay to play"

Florida high performance built my last engine... Erik is Awesome.

Erik is exactly who I am speaking with. Nice guy, has great reviews. Im looking at the initial build below, then possibly go heads cam. He won't do cam only due to many dopped lifters he has seen. His Head/Cam price is not cheap at 12.4k, which includes tuning. The initial build is below-

Vettethret - Well, if this makes you feel better. I've done nothing but bolt'ons. So, no internal mods, no CAM, on Oil pump, no heads, not even upgrades for DI etc. What's in my signature below are all full bolt'ons. So, including the current work being done by Katech for the port injection and other misc. goodies. I'm at $26K. That's with me doing all the labor possible except for what Katech is doing for port injection. Back in Feb 2023 when I purchased most my big ticket items, it seems prices were higher than they are now. Good luck! This is a journey well worth every dollar spent !!! (my tires are obviously not included in that $26K amount!)

Meth? some on here love the meth "for cooling" but that's a myth. A meth car is always meth dependent. Turn meth off and beat on it a few days "if it lasts" and tell me different. Oh ... it will just run hotter is also a myth. I get alot of people love the meth but I'm not one of them. Too High PSI and a DSX aux pump and run E85 is the current hot setup. Pull up to the pump and fill up and off you go. No other hassles

yeah well, this new THPSI and Katech pumps combo is going be the best/most capable setup you can do with these now. a lot more fuel delivery, don't have to tap tank or worry about fuel pick up issues. A lot more room to grow.

You certainly CAN run it just for cooling, but it's mostly used as a fueling source it seems.

If you run a 50/50 water mix and tune fueling and timing without meth spraying, then turn meth on after, you get the cooling effect. Only change is a slight richening of the mixture. If meth stops spraying, no biggie. It leans up back to where you tuned it, and you didn't add any meth-dependent timing in the first place.

I'm with you though, either run E or get a 2650 (or both). Cooling problem solved.

No one does that ... no one - alot of "if's". Its basically poor mans fueling to crank up timing and HP. Yes there obviously is a cooling element and alot of people post they run meth for cooling but its for HP. And they are meth dependent. Just my observations.

If you know anyone running these pumps right now I'd like to read up on them. I have been waiting for some cars to have miles on the road with these

scroll to bottom to see dyno numbers, he just got his car finished with these and THPSI. No engine work, pretty crazy

10K or so for the dual katech and a lingenfelter high side pump, injectors and flex fuel. This is on a cammed Maggie 2650.

yeah the DI shit is so expensive and still can't flow what the port setup can

Yep but it makes more power than port. So running as much DI as possible makes sense.

I pull up and fill full E Without any hassle at all. As well. 🤷🏻
Its the same risk if you intank fails, if your high side fails. Same risk. And they are also aftermarket (when PI) What guarantees you that they wont fail?

Heck, my LT4 HPFP failed on the dyno idk. Its a risk regardless
