Anybody switch from the 35 to the 55? Now that our warmer weather is here, my engine temp is climbing....I have a good rad. Its also the biggest rad that would fit. Never had a cooling issue. But idling around she is starting to get up there. When I called Meizere, they told me it should work. Trying to keep it under 200, but its not possible anymore. Must be making too much power.

I am debating doing that. I recently switched out an OEM mechanical pump on my drag car for a FlowKooler mechanical. Drops right into the OEM housing.....I may call them tomorrow and get their opinion.
And man that unit works well on my drag car until I go to back up and then she will climb maybe 10....But from the launch at 180, down the track at 180, and all the way back, 180...Go to reverse and park 190....And that car has a small rad and two crappy electric fans. Not really optimized like my Hemi street car. The drag car used to get to 195 during the run and then 200 all the way back.
I would have to buy everything, a housing, the FlowKooler pump, and a full set of pulleys and no one makes a kit for a Mopar with a cheppy alt, water neck, and probably a different alternator and belt. The pulley that is on the current one is ON there!

What are you using for fan and shroud? High temps when slow moving and idling around is often a fan issue.

I sent my 35gph pump back to mezeire and had it upgraded to the HD unit which i believe is 42gph, it seemed to help quite a bit driving around on the street.
It was fairly cheap too, around $150 i think.
My combo is 496 at 12.3 - 1 compression, will ride around on the street at around 195 or so once its fully warm.

I've always run the 42 GPM Meziere that drops into the stock housing. It does pretty good, but I'd like it to be better.
I can't fit the big 55 GPM Meziere pump due to my fan and I'm not willing to change that, so my only option is the CVR 55 GPM pump that also drops into the stock housing.

What are you using for fan and shroud? High temps when slow moving and idling around is often a fan issue. I have dual Flex-a-Lite fans with built in shroud stuck right to the rad....But that also might have to be improved....Since I bought those, I see they are making better fans....The rad is 19x31 and supports a pretty good sized fan setup. The BeCool rad is rated to 1000hp.....and I have it sealed to the front opening of the car. Almost all the frontal air has to go thru it. I think the fans were rated at 2500cfm back in the 90's when I bought them. With a core of 27x18, I could switch to the newer S-blade style and pick up 500cfm. Ignore the injection...I took that off some years ago. https://www.summitracing.com/parts/flx-490/overview/

My issue was not enough fan. That completely eliminated my street driving issues. I assume you arent running without an obstruction to slow flow down( hogged out stat works good) running with nothing in the way doesn't work. Fan(s) that way wont have time to cool the water. It needs slowed down. so you can actually cool the water while its in the radiator. When looking at fans i have found the cfm ratings very inaccurate, all over the place. If they aren't drawing a lot of amps, the motor isnt up to snufg. I have seen stuff they say is 3000 cfm and draws 7 amps. And a fan that draws 20 amps and is rated at 2500 cfm cools WAY better. More amps, more likelyhood the fan will cool well. More amps, better motor, better cooling, more money. I like Derale stuff. US made, excellent motors. They make a dual fan 4000 cfm unit that is heavy duty

Well, I run with a 160 stat that has a couple of 1/8th holes in it. Talked with Meizere and they said run without the stat....But as you said I thought the water needed time to loose the heat in the radiator....I am confused.... I just tear the center guts out to slow the water down

So I hollowed out the thermostat today and will try that....What a PITA ....First attempt the o-ring on the housing leaked....2md attempt after cleaning off ALL the old sealer and putting a very light coat of sealer on, leaks......3rd attempt, still leaked....So now tear the whole thing apart, wire wheel all gasket surfaces, and put a ton of damn sealer on.....No leaks, but I hit nicked the mechanical temp sensor line...Guess what, now no gauge.....Go to two stores, buy a new gauge, finally install that....No leaks and finally a temp reading.
So I will try this out without a stat....I can tell you I could not get the car to full temp idling in the garage like I usually do....What it does down the road, I am not sure.

I run the Meziere HD 42gph in my 440rwhp 440cui block with two spal fans (16" and 12") with a 31" triple pass Radiator.
No issues even at 100F. Outside Temperatur does not matter or how fast I drive. It will be, after a while, locked between 200F and 210F (gauge is ok :-) )
Without a T-Stat! If I use one, it overheats. In my opinion the water can go only to slow. It is a closed System. The faster the water flows, the more often it sees the Radiator.

FWIW...I run no thermostat or restrictor per Meziere's instructions. I have wanted to try a restrictor just to see, but never have.
