Re: What manifolds allow full radiators?
Depends upon what you mean by full sized radiators.. Some can show oem radiators with slim fans on the opposite side, while Dunne can hold a VW sciracco (sp?) Radiators.
Most others only like we've discussed before: log and tubular log manifolds

Re: What manifolds allow full radiators?
I was all set for a half size until I started reading stories of overheating on the Integras due to no large opening for air like the Civics. Those with half size radiators are having to run fans even while on the highway.

Re: What manifolds allow full radiators?
It's not the size radiator or even where it is located. (If that were the case, even the stock civic radiators wouldn't work on a stock car..) like an intercooler, it's the type and brand radiators you get, not to mention they proper cfm fans to go with it.
Fans chime on briefly on highway driving no matter what, but especially after some good accelerated runs.That's perfectly normal.. That's why thermostats are there; to regulate when coolant needs to be exchanged in the system..
Stick to Koyo,Fluidyne, Skunk, and even Mitshimotos (to a lesser degree IMHO), with good fluid and the prior fans and you're more than fine

Re: What manifolds allow full radiators?
That's because they're using cheap low flowing eBay radiators, s n all fans, and never addressed simple issues like air pockets in their coolant systems.

He has a stock 2 core B series half radiator I think
If I could run a half I would rather do that for simplicity but I want to be able to open road course this car possibly sometimes and I'd like to not have to worry about things getting too roasty.

LightningTeg is having problems now as well and I'd like to think he knows what he's doing. lol

On average about 194*F for street, about 200*F-204*F after 20 minute Session Time Attack, but goes back down to 191*F at the cool down session.
I'm only looking at a possible full size because my attack sessions will be getting to about 40 minutes after some time. But right now, never a problem.
For a street car. that combination will do more than enough. Even some Full sized radiators won't get as cold as my Koyo.
Lighteningteg is changing setups completely, so he's not having that much of a problem.
I'm sure you're not worried about getting some sidwinder manifold for the purpose you've discussed. that's just above and beyond what you'd ever need.

Re: What manifolds allow full radiators?
I'm open road course 3 years on VIR, Gingerman, and Mid-Ohio. Half sized, Koyo Rad with SPAL 13" 1800cfm w/ bracketed shroud, using straight distilled water for the course. Switch out to 70% Toyota coolant, 20% Distilled water, 10% Royal Purple Ice.

I believe I will copy your setup. Do you run a JDM front or USDM? I believe I remember your car has JDM, if so I would imagine that would effect airflow.

Re: What manifolds allow full radiators?
Like I said.. I ran with both front ends, and I have a real-time water-temp DEFI gauge it in the car that records the runs.. It wasn't significant at all. THE RADIATOR itself determined more than that source of that little inlet.

Re: What manifolds allow full radiators?
No. Unfortunately, I don't. But no, it was not "cake pan" style as that is advertising. I used the fan shield itself to surround the edges of the radiator, and attached it with custom brackets. It covers the main surface area of the radiator, without the need of a rattling "cake pan" style shroud.

What ems are you running op?
Can you see ect voltage based on coolant temps?
I found my voltages to be way off in my ems and adjusted based off when the thermostat opened and closed and haven't had a problem since.

Re: What manifolds allow full radiators?
I only really starting having issues when I put that big ol intercooler on. Car has a triple core Mishimoto X line "half size", downpipe and manifold are wrapped, turbo has blanket, and it runs straight water with water wetter in the summer with a SPAL 13". Fan will kick on and off every 5 minutes on the highway from about 50 deg ambient temp and up. If its 90+ out it will hang around 200 after pulls and I have to let it cool. Fan kicks on at 196.
When I had a stock setup with a/c and everything still, my full size never really had an issue. Theres still room for improvment, but it will require some custom fab work. I tryed to make a "cake pan" style shroud and not sure if it made a difference or not. Its just some sheet metal I had made at my old job (sheet metal shop).
Id like to try a scirocco rad to move it away from the manifold some more. And next year I wont need such a large intercooler and will upgrade to a more efficient core.

Re: What manifolds allow full radiators?
Could be a dumb idea but Lightning have you tried an air deflector at the bottom of your radiator? I know I have heard in some make and models it makes a difference. Just food for thought.

My solution was to put a heat extractor on the hood

Re: What manifolds allow full radiators?
I run a Koyo Radiator, Maradyne 12 inch 1650 CFM fan with a mishimoto fan shroud in Arizona and never go over 201. Typically my car will get to 198 or 199 and when my fan kicks on will get down to 193-192 quick. I used distilled water and water wetter.
those three items you should never have issues overheating unless you have a problem with an air pocket or a head gasket issue. You should also heat coat your downpipe, dump tube, manifold and housing to help reduce heat. They also have clamp on heat shields for downpipes as well for extra protection which is what I used. see below.

Re: What manifolds allow full radiators?
Lighteningteg's issue was one of using a really dense core (Garrett's are like that) with a stock radiator, and that can cause an overheat issue, not because of the size of the actual surface area of the radiator. The stock radiator (or sub-par aftermarket designs) can get sensitive to the efficiency of the intercooler core, especially if its a BIG one. I actually changed from my C&R radiator to the Koyo because of this issue, as I changed from a GReddy Tube and fin Type 24, to a Garrett 24 X 12 X 3.5".. Once I did that, all was well with the world.

Re: What manifolds allow full radiators?
Whats funny is I originally bought a "triple core" half size from Ebay and it was nothing but overheating problems. So there definitely is a difference! I think I may go for a Koyo since it seems to be the standard for high performance.
