For me 9 gallons of ambient water It's going to help inlet air temperatures for quite a while. If I want to get serious about a hit, I put ice in the tank and turn on the pump

If your seeing 140 to 150 IATs on your 2650 something is wrong. I had not additional cooling mods except the larger LTR up front which I have on my 2300 build we are doing right now. When I switched from 2300 to 2650 back in 2018 my IATs went from 140 to 150 in the traps to 110 to 115. Something is not right and you shouldn't need additional cooling with the 2650. The bricks are huge, do you have a air pocket in the cooling system?

I didn't log my 1/4 mile runs, so I'm not sure what IATs were start to finish. I was only watching the temps on my AF gauges, both IAT1/IAT2 were sky high. On my first run of that night there was a very nice C7 Z06 in front of me. Both of us had our hoods open while in line, trying to manage the obvious heat soaking that evening.

I'll have to carry my laptop and log some daily drives to get a better look at how the temps are moving up/down. Now that we've broke out of the 100 deg. summer heat here in SW Idaho, I won't be too worried about it. Just working on ideas to keep me busy during the winter months when I do not drive the car much at all.

Thanks for the PM, lets figure this out.

Ted is a wealth of knowledge and has already helped you with your build. Id say stick with him and see what he says

In the case of a ZL1, there is an IAT3 or Manifold Air Temp sensor, and that is what the computer references to determine if it should pull timing from the car at higher temps.

At the top of 6th, IAT 1 and 2 are 73/84 respectively, but manifold air temp is 190. The engine coolant temps are cooler now by 20-30 degrees

I'd agree with that but I'll be glad to help you out also. Been there and done all of it. Give Ted a call to let him know whats going on.

Holy cow! 190 is really high for MAT, no matter what gear or RPM it’s at.

Op, it sounds normal to me based on the conditions. Once the engine is heat soaked on a really hot day the coolest you are going to get the system to recover to is the 130-140 range. There is a big difference comparing how the cooling works on the street vs the track. At the track you make a 1/4 mi hit which isn't very long, bring the car back to the pits, pop the hood, put a fan and/or ice on the supercharger. It will cool right down in 45 minutes. On the street with normal street use that isn't very practical. This is why some use a interchiller.

Perhaps with stock cooling, just not enough fluid moving around to keep its temp down. The cooling setup I have now with stock HX’s would allow temps to stay under 150 even with the old Whipple 2.9 while running for 2 hours through the mountains. The Maggie runs 20-30 degrees cooler in every scenario I’ve tested.

LOL, I agree. But it's inconsistent with the other lower temps. Perhaps the sensor is mislocated?

Not sure what the options are for the Edelbrock. There are two on the Maggie and one will show a little higher temps. Even then, 190 reminds me of an over-spun stock blower with no cooling mods. Maybe air in your lines? Are you sure the pump is running at all times and doesn’t possibly have a loose ground or something?

Yea, something's not right. MAT on my KongX thru its last run was 129-167.

I do not know if the pump is working properly but I'm on it now.

Update: Just made my usual jaunt, and MAT spent most of the time cruising in 90s and between 110-120 at 7000rpm, so the mystery continues. Not sure about the log data the 190 reading came from.

Fender tank would be a good start. I like the Synergy unit.

Trunk tank with EMP would be the best but not everyone wants to go that route.
