I'm looking for a little more cooling with my setup, The half rad seems to sh!t the bed when it gets over 25* out. I am looking at putting an additional rad in the wheel well/fog light area to see if that will help. Question: -Can I throw a "T" into the upper and lower radiator hoses and run in parallel? The other rad will most likely have smaller in/outlets. Will that actually work, or will the coolant always choose the path of least resistance, and leave one radiator to do all the work? Probably a question for the engineers

Path of least resistance. I would just weld on some bigger outlets.
Also pretty sure you can just use the factory SMIC as your secondary and the ends are the same size. And adding all that extra coolant will have some cooling properties too.

What if you did an electric water pump what is T'd into the current coolant system using just a helper pump? I've got a spare water pump controller to make the job easier. Just get a harness for it, a small pump from Davies Craig and then a relay and fan.

The way the controller works, is you tell it what temp you want the car to run at. Then it regulates the pump speed and fan to maintain that temperature. The spare controller I have is the previous model as of just a couple months ago, but if you dont want to look at it, then you can wire an LED on the dash for it to turn on should the temps get too high.

Haha Mike, I would do it one at a time, who knows maybe all the extra water from adding the extra plumbing and side mount will be enough to cool it, if not than you can add the pump and all the fancy stuff.

I don't think you will find anyone here on this board running tap water, there has been plenty of pictures and info on why you shouldn't use it.
Mike are you using water wetter? I know some guys have noticed some good differences

I ran water wetter years ago, and it worked well, I am not currently, I will probably throw some in before the shootout If I leave things as is.
I threw in some dryer ducting from the one foglight hole to the rad, and some pipe insulation around the rad, and the car seems fine on the highway. I actually did a couple pulls last night and don't think the fan even turned on.
It's just when its a shitty 30* out and I'm doing under 40 in traffic, or waiting for stop lights, things get pretty hairy pretty quickly.
I would love to run in series, I just wish I had some elbows and a Tig at my disposal to route everything how I wanted.

What fan are you running? Maybe you just need something that moves more air?

What fan are you running? Maybe you just need something that moves more air? I'm not too sure, I've been using the same fan from Canadian tire's back shelf that I got at the Invasion in like 2009. And what coolant mix are you using? As Mike mentioned above, going to a 70% water/30% coolant mix can make your system more efficient. I think that is about the mixture I am running, it is from the hose so I suppose I should grab some fancy distilled water.

Haha Mike, you will get mineral deposit build up on your water pump so get the distilled in there!!
I think the fan could be the culprit especially because you are most seeing issues at slow speed.
