Looking for an aluminum radiator asap, N/A car, 2001 NB. Anyone know what the lightest one out there is? (metal and fluid both)

 

Lightest one would be stock I would think since its the thinnest and has plastic tank ends.

 

Best compromise would probably be a 37mm KOYO or 37mm PWR. The PWR ain't cheap.

Other options is an all-metal dual core OE replacement...which is copper/brass.

 

Stock = lightest
Anything that is considered an "upgrade" will hold more fluid and therefore be heavier.

 

The one that holds the least water. Think about it.

 

The CXRacing I have is like $100 on ebay and it's aluminum. It is one of the parts that dooes NOT give problems in my car

Fluid temperatures is one area that is universally known to be worth the extra "weight'' of a larger heat exchanger.

 

Yes. This thread sucks erin.

If you really want the smallest lightest one then run some dinky honda radiator.

 

Dinky honda rad, means the ic piping can go right around it, Not under the car. Shorte trip means less piping.
Double weight savings win.

Thought about doing this actually, but I didn't want to remove the ac condesor.
So I went with a giant dual core all aluminum rad. ebay, works great so far.

 

Also, note that Sean did this- run honda rad. I think that his car ran hot. Just run more boost erin for better power to weight.

 

Bringing this back up. Are there any good options (besides more boost lolz) for a lightweight radiator, or just stock?

 

stock or 37mm koyo

 

I've owned a 37mm Koyo before. It wasn't the lightest ever.

 

Are you sure about that? What did it weigh and how much did the non-OE alternatives weigh?

 

for lightweight? Run a large oil cooler. The lowest capacity radiator is still going to be the lightest, as already mentioned in this thread.

For lightweight, but still efficient enough to actually cool your engine? Run stock.

 

Stock. It's definitely the easy button when it comes to light and you're willing to sacrifice some cooling to get it. (see also those silly cars that run for 60 seconds at a time, between a bunch of cones, the weight obsessed run a stock radiator.)

 

Am I sure what I owned?

Well, it might have been in the matrix, but I'm pretty sure not.

And I don't think there were any drugs involved.

Contacting Sav. Probably just get another TSE rad.

 

IIRC the Koyo 37 was ~16lbs. Stock was 9, stock automatic was 11 (all full of water).

 

TSE is obviously best for HPDE/OT, but damn. It's hard to consider more than doubling the weight of a stock part. Especially all the way at the front of an already front heavy car.
