C&R to stock radiator comparison question

[450madman]

I thought an aftermarket oversized radiator would be a little wider than this. Does this look about right?

[D Bergstrom]

The pic you posted is only showing the tanks, those are usually close to the same width. Where aftermarket radiators are thicker is in the core area.

I noticed the cores being a little wider. I honestly thought the tanks and cores would be alot wider than the factory unit. I just wanted to make sure I didn't buy an oem replacement marked as oversized.

Looks nice. Were you going to mount your factory screen in front of it or what were your plans?

Another nice thing is the about the c&r is the cross flow design, it gives a little more cooling time when the coolant flow is sideways vs. verticle...

It's a dune bike so I was thinking about leaving the screen off. Not sure yet though.

I've never seen an aftermarket screen for sale so I wasn't sure what most people do.

The fact is that C&R did make both oversize and stock replacement size. A member on here recently sold a bunch of stock replacement size ones and based on the condition, I'm pretty sure you bought a stock replacement one because I had a C&R oversize before and it was quite a bit wider than the stock by about 50%

[laeger400]

The ones that I sold where stock replacement ones. These are the same ones that Walsh had used in there hybrids. You won't be disappointed with that radiator.

[450madman]

It better be oversized. That's what I paid $300 for. It's used, but clean.

[laeger400]

That radiator was around $400 new from Walsh and atv innovations

[450madman]

I'm just worried that it won't much better than my oem radiator. The C&R is older. I noticed this engraved on the side - W.O. 24138 8-18-03. It took me a while to pull the trigger on buying an aftermarket radiator so I want it to be worth it.

[laeger400]

I think you will be fine. If you don't want it I might be interested in it. Pm me some pics.

[450madman]

I'm asking the Ebay seller what he knows about it first.

I would run it without thinking twice.

[450madman]

I have a chance to get all but about $15 of my $300 back. Your saying it's worth it to keep it instead of getting the oversized one I wanted? Wish I knew the temp difference between the c&r replacement & c&r oversized.

[laeger400]

They work well with the 4stoke hybrids I don't think you will have any issues. C&R doesn't make them anymore. You can have them make one as a custom order but it will be real pricy. It's your call.

[450madman]

Thanks

I am going to say not much. Cooling is from air moving over the fins. Yes, the thicker radiator will have slightly more area, but it is perpendicular to the airstream. I would guess the surface area exposed to direct air is probably close to the same. I ran a Griffen radiator for years that was just slightly bigger then stock on my 330, never had one temp issue, even while riding in over 100 degree heat here in Vegas. I think the radiator you have will work just as well as an oversized one.

I can tell that this c&r would cool better than the oem. Just didn't want to regret not sending it back
I've never overheated or anything with my 310. I want to run a little cooler for power and help reduce the chance of overheating in the future.
You can see more area for cooling by this pic

[latheboy]

Is the C&R dual pass? When I bought an oversized radiator, thats what I was more concerned about. The AFCO and my Pro Series circulate the coolant thu the radaitor twice before returning to the water pump. Any way you go, I think you will be just fine with a 310. A 350 in at the dunes, maybe not so much.

[450madman]

Not sure

[450madman]

So what do you guys think this is worth? I may return it tomorrow for a $300 refund. I would keep it but i'm affraid I would be over paying for this factory replacement, when I can get a clean oversized for the same $$$.

[450madman]

Small amount of bent fins on this side that can be easily straightened.

[Honda 250r 001]

Dude, keep it. If oversized radiators were wider, rad shrouds wouldnt work. I dont think you will find many at all that are wider or taller. I bought a PWR oversized and its just thicker. Run it. Thats a pretty good price for a radiator. It looks pretty well built to me.

[laeger400]

We have all told him it's a great radiator. His mind is made up that it won't work. Just get your money back and you will be happier. I worked for a place called velocity racing. We built turbo bikes and shootout bikes. This guy brings us a brandnew busa. Spends 45k on his build. Stage 3 race kit with a full race engine. We cut 4-5 rows off the bottom of the stock radiator for clearance for the turbo and manifold. He goes home and calls us. Says it's over heating. We ask what he was doing. He said it's been sitting in the driveway idling for 45 mins to and hr. We said ride the damn thing and it won't overheat. It's not built to sit and idle. This bike made 430hp at the wheels with a smaller stock radiator and works just fine. You have to ride it. What you have is a badass radiator.

[450madman]

Thanks guys. I'm keeping it. I was just wondering what it might be worth because I feel like I paid the price I would pay for an oversized. I'm working out a price right now with the seller. Thanks for your input, I appreciate it.

if there was still debate on if it is a stock replacement or a larger unit i can say that it is just a stock replacement. i bought a C&R dual pass and mine was alot thicker then that. Should still be a great radiator though

[450madman]

I ended up getting it for $150. Now I'm happy. Thanks guys

Exactly. It all depends on what your quad actually needs.

A while back, there was a test done on intercoolers(basically a radiator for the intake air after a turbocharger compresses it and heats it to hell) for a newer Subaru WRX. The stock one is fairly small and made of plastic. The aftermarket one was twice as thick and aluminum and looked 1000 times more awesome. Definitely had more potential to outperform the stock intercooler, and chances are on a road course it would have. But as it turned out, there was nowhere near enough airflow in normal "around town" every day driving to cool the big core of the aftermarket intercooler, and the little plastic stock intercooler was more then capable of doing the job under conditions most WRX owners drove in 95 percnet of the time. So not only did the aftermarket intercooler cost a bundle, but performed worse then the intercooler that was already on the car!

Not exactly apples to apples, but bigger is not always better. Just depends on what you actually need.
