Need some input on turbo'd integra cooling.
Have full size single core radiatior, 50/50 coolant-water burped for air bubbles, SPAL fan 1300cfm (somewhere around there), turbo heat blanket, DP heat wrapped, dumptube heat wrapped, hood vent, and custom log manifold heat shield.
So I have a center hood vent like such:
it basically vents right over the manifold/turbo/rad
The manifold was not heat wrapped or shielded previously, but just yesterday i added a thin aluminum heat shield like this...
...to the manifold in hopes of dissipating some heat, but im not sure if im now trapping the heat in more.
Would it be better to let the manifold radiate heat up and out of the vent?

Gonna find lots of opinions on this matter, for sure. Me, personally, I don't use any wraps as they tend to trap moisture.. I don't use heat shields either. I keep it all natural and while under hood temps get warm, they do not cause any concern under driving conditions. Now, when I drive a bit then stop at the store or something, yeah, heatsoak is a bitch. Lol! About 5 minutes worth of driving again brings it back to normal. Anywho.. Pics of your setup will definitely help with any other recommendations.. 😉
I think the heat shield is a good idea because it will stop some radiant heat from getting into the radiator. It will also probably make the turbo setup get a little hotter, but I cant imagine it would be much a difference.
Hood vent placement sounds good to me. That should be some of the highest velocity air on the hood, so low pressure.
Dont overlook sealing off the front, ducting, etc. The better you seal the front of the car to the radiator, the more effective the radiator will be.
You using good hardware and a well built manifold? Those are the things that fail from turbo heat on the track.
If youre having issues with studs stretching/breaking and nuts loosening, Inconel hardware is the best fix imo.
I will post actual pics of my setup. The car is a daily and the stop and go heatsoak is what im worried about. Oddly enough driving the car before adding the heat shield to the manifold, I never saw my CEL for temp kick on but today WITH the shield on right as i pulled into my work the CEL popped on.
My other thought was to add a small vent/duct in the bumper to let more air get sucked in like this:
Stop and go is a different beast. I would suggest building or buying a full shroud for the radiator so the fans can pull a vacuum across the whole surface. You can even put little bypass "flaps" in there if youre concerned about it limiting airflow at speed.
Remember. Your engine is not aircooled. You need to make the radiator do the cooling, dont try to cool the block/turbo/etc.
I found a few out there for the full size rads
EDIT: Also, you can run straight distilled water with Redline water wetter for max cooling. Or run a lesser mix of antifreeze with watter wetter if youre super worried about corrosion. Just make sure to get some antifreeze back in there if you expect freezing temps. I see youre in Orlando so idk if it ever freezes there.
I have a half shroud made from a baking sheet thats got like an inch of space to pull from. I guess i could find a full size shroud but i def dont have space to run two fans. The one fan I have is already pretty close to my turbo intake.
I also havent "overheated" really, like i said today was the only day I saw the CEL hot light come one, but normally its been fine (granted i dont do rips and then sit in stop and go, i usually stay out of boost).
Im in FL too btw so its 90+ everyday with 90% humidity lol.

My NA B series setup would sometimes get up to 210-215 in peak summer in stop and go traffic. Im up in Jacksonville, so similarly hot.
This was with a full-race half-ish radiator and a Spal fan, running straight water and water wetter.
I finally managed to fix it by squeezing an OEM fan and shroud in there. Idk if it was just because of the shroud, or maybe the fan actually way outflows the Spal, but it worked great.
Since oyu already have the cookie sheet shroud on one side, maybe you could put another fan as a pusher for the other side? or is the intercooler too close?
ill take some pictures when i get home so everyone can get a real idea with what im working with. If i could get a SPAL or similar with higher CFM without the fan motor running into my turbo intake, then I would try getting the highest flow fan I could in there just to be safe, but i know the 1300ish one I have definitely moves good air, maybe the half shroud just isnt cutting it
Not sure if you can make out here, but i have two abs pieces directing air towards the condenser/radiator. Hood vent. Has the gurney flap for better low pressure creation. Ill get more of the rad/turbo/fan
So drive home pretty much overheated but found out my rad fan wasnt blowing. My SPAL pulls 13amps, anyone know what the stock Rad fan fuse/relay is good for?

I highly recommend running a relay with larger gauge wire, a 40A fuse, and setting your engine management to run the fan at all (most?) speeds. I think stock, the fan turns off when the VSS is over 30 mph. I have mine set to stay on until the VSS is over 90 mph. I think you should wrap as much as you can, and the heat shield is a great idea. My car is an EJ1 Civic, so different front aero to deal with, but I'm running AC as well, which complicates things. I struggled with temps at first, but feel like I have a good handle on it now.

Can i just run a 40A fuse in place of the stock one and upgrade the wiring to a larger gauge? Or do i need to run a larger wire from the battery with a fuse to a relay?(like the SPAL kit)
Can i just run a 40A fuse in place of the stock one and upgrade the wiring to a larger gauge? NO. Or do i need to run a larger wire from the battery with a fuse to a relay?(like the SPAL kit) Yeah, this is how you do it... and use the original wiring to activate the relay.

So do you think the whole overheating issue was because your radiator fan wasn’t turning on?
This. Heatshield beside the point, with your current setup you shouldn't be overheating. Something is off.
Make sure you have a proper shroud for your fan(s)
Nah its true.
Integras have **** poor engine bay airflow. I had the same problem with mine and did all the tricks short of cutting a hole in the hood. Just learned to live with my fan running alot

In another post he mentioned his fan isn't turning on and he never did the fuse/relay upgrade for his SPAL.

yeah this is obviously my main issue. Just ordered the SPAL relay kit. Prior to this overheat when the fan didnt run, the fan did seem to run alot, thats why i added the heat shield. Just to see if it helped any.
ill get a real feel for the effect of it once i get the fan wired up correctly.
