Has to do with pressure. The rule pump flows when it doesn't have any resistance. Once it sees pressure the flow drops drastically.
The Stewart pump is by far the best flowing i/c pump out there. Flows somewhere between 10-15gal per min. Its crazy, flows better than my garden hose

The RULE 2000 is 33 gallons per min, what's the spec on that Stewart pump?
Definitely listen to the guy posting in front of me.
The Rule bilge pumps are JUNK for your setup!
The can’t move water well under pressure/restriction.
They are great with 1.25-1.5” lines and big aftermarket intercoolers with all fittings and lines BIG.
As soon as you put the Rule pumps in a factory system the flow drops off.
I have a Rule in my drag car, but for a stock Cobra intercooler brick and small factory lines and fittings, the stock ‘13-14 GT500 pump or Stewart are what you need for total system flow.

That's very interesting. I'm gonna see about upgrading the pump in my trunk tank. Those Stewart pumps are like $400 from summit I think

They are, like I said not cheap. But once you turn it on you'll see the difference right away.
But I don't think the pump will make a huge difference by itself. It needs to be paired with a better cooler and bigger lines. Everything needs to work together

I know it’s a bummer. Like I mentioned, I have a Rule 2000 in my built Foxbody, but the system is designed with minimal restriction.
These OEM air to water intercooled cars have smaller cores and restrictions in the lines/fittings, so it’s a different animal.
I’m waiting to hear more about the new ‘20 GT500s, but the best OEM pump is the ‘13-14 GT500 Peirburg (also supplier for the ‘20 GT500s and AMG cars).
If you want to get funky, you can also consider a BAP under a Hobbs switch but that might be overkill.
And also like above, it’s a systems approach, so what are you working with now?

Glad I could be of service :). I wish his i/c core was available when I built my system. Ill grab one soon, my financial situation with this virus is a little rough right now. I'll stick with i think the gt500 aftermarket h/e is still a very nice option if you don't want to shell out for his new h/e.
It's a lot of $$$ up front but if you need low iat2s its the only real option. Especially if you live in hot climate like me. Good luck bro

Anybody have any knowledge and or data about how the J2Fab HE does in comparison to say a typical AFCO double pass setup??? Im weighing my options
/cost here and debating on if bumping up to 1" lines with the flow-mod plus the new IC is worth the cost for a upper/lower Cobra. At that price point im considering just going whole hog and getting the HE as well.

However I dont believe Ive seen/heard anything on his new HE as of yet, has anybody???

Here’s some good data to peruse during quarantine, including common pumps and ‘large flowing’ pumps such as the Rule 2000 and Mezeire EWP:

There was a good thread on this topic on Yellowbullet.com that included a tech guy from Lingenfelter posting their research, but I thought some of that was lost, thankfully I found some here.
As others have said, treat it as a system, not just a pump or ice tan’.

there isnt much info on the h/e. maybe email him or message him through FB and see. ill be sticking with my gt500 vmp unit.
i an tell you there is no caparison between the 03-04 cobra units and the 13-14 gt500 units. its literally over twice as big.
however he does make everything with an fittings now so that make sit so you with have to retro a one of the parts or buy all of his stuff

That’s literally the same thing I was thinking regarding the $$$ to be spent. But I’d really like to try his heat exchanger and I/C because being at 30psi generated a ton of heat from my Gen 2 Whipple Crusher.

Having his 10 gallon tank wouldn’t hurt either because aside from more cool liquid flowing throughout, it’ll help aid potential traction issues too.

I’m new to the page. I am finishing up a whipple swap in my 03 Mach 1. I have the J2fab intercooler mod. How are you guys running the 1 inch hoses from the water manifold to trunk mount tank. Thanks for any help

PM me & I’ll help you with routing the lines and everything you’ll need.

Should be good to go from a pump standpoint, just need to maximize the rest of the system.

Yes! Especially because I’m running tests on high boost applications, so I’d really like to see the data on IAT2s with J2Fabs complete system.

I don’t have the ability to pm yet. So I need to post a few more things to get access I guess

Kind of hard to describe but I'll give it a try:
Come out of the trunk water tank to the pump, shortest distance possible and gravity fed. Leave the pump and go to the front. I went through the trunk pan between the spare tire and the back seat. Watch where you come out, you don't want to contact the irs or axles or anything else. After that I basically followed the fuel lines. Run under the passenger side, through the pass fender well and enter the engine bay. Or you can be stealthy and run them through the ground effects so they are hidden. Easier said than done. The lines are big and don't route easy. Plus you want to keep the as free flowing as possible. Do a few trial runs before you cut anything. Make sure they are away from heat and anything moving. And keep them tucked close to the body, don't want them getting caught. Good luck

J2's HE vs. VMP's triple pass gt500 HE, who wins?
I'm debating and been "learning" what I can from various websites and forums... From what I've read, FLOW is very important for low ATW temps. The best description I could get was from departmentofboost, they go into very good detail and compare various HE's on the market and stock HE's as well. AIR Flow is an important factor as well, From what I gathered triple and double passes on an HE can restrict fluid movement making FLOW harder... with that said, Is J2's better being a single pass, vertical flow, -20an and the core being no thicker than 2" for efficient Air flow through the HE? Or... Is VMP's triple still viable IF you go with an EMP pump? I wish someone would compare HE's on the market with ATW temp numbers... It could be settled
I am in a dilemma with who to go with VMP would be the most reasonable priced IMO BUT! It can't be denied that J2's HE, according to how HE's work, his is the best option.
I have already ordered his flow mod and IC also have his 3 gal engine tank... emp soon
I need fans because I do a lot of idle driving leaving my home and coming home and also do some driving out in "mexico" ya dig... should I go with vmps deal or j2's and buy a couple fans later
