Many may recall the radiator and fan tests that were condutcted last October. For those that missed out these tests were conducted to gain data and dispell myths and misinformation regarding cooling options for the sr20det(obviously applicable to KAs as well). The tests were conducted by David Money(fsae_alum), Kevin Vancleave(Over_Center), Adrian Romanyszyn, and myself, Bradley Denton. The site has been down for a while and many people have contacted me regarding the tests. It has taken some time but the page is available again. You can find the site at its new home here:

SR20DET Radiator and Fan Comparison Test (http://home.satx.rr.com/nissanweb/RadTest/RadTest.htm)

Hopefully this information will help people to make an educated decision on what cooling setup fits their needs and budget. Enjoy!

Now I'm just wondering how you wired the electric fans up. I dont know how I should do my Altima ones =/
A sketchy wiring diagram would be nice, where you put the relays if any or anything like that.

He used a greddy MSS with 2 30amp relays if i recall correctly. exact same thing i did. If you search you'll find up his full write up on them.

By the way, thanks for doing that it was a huge huge help!!!

Also from what i saw on the site the copper koyo is the king of them all??

I think it was the C&R Dual that was the king of them all. But the bang for the buck radiator was the Koyo copper/brass.

Why think when you can just go to the page and see...that it was the Koyo copper/brass.

Wow, that was a lot of work. I am very impressed. It looks like a lab report for a college class.

Nice to see the test back up. I would love to do it again with the radiators I designed after the test. http://forums.freshalloy.com/images/graemlins/grin.gif

very nice writeup!! the thing that suprised me the most is that the alty fans pump more air through the radiator than flexalites do, crazy.

Thanks for getting it back up Brad. Ahhhhh...those were good times.

Sorry everybody it took so long to get the webpage back up. That's all my fault as a result of moving to CA.

Thanks Brad!

This is an excellent right up!!!! I was just thinking about how to handle my cooling issues too. What if we ran the plastic under panel and used the L bracket. Would that help even more. Also the which fan was the SPAL High profile fan?

I checked their site and here are the list. Which one did you guys have just for clarification?

30102113 16" Extreme Performance Pull Fan 3000 CFM
30102036 16" High Performance Fan-Pull Straight Blade 2360 CFM
30102047 16" High Performance Fan-Push Straight Blade 2360 CFM
30102049 16" High Performance Fan-Pull Curved Blade 2070 CFM
30102048 16" High Performance Fan-Push Curved Blade

It was the 30102036 16" High Performance Fan-Pull Straight Blade 2360 CFM. Enjuku's twin S13.5 drift cars have been using the 3000 cfm fan, with good results.

Just to give a VERY brief report on my C&R DP radiator. It is hotter than a $2 ***** here in Florida. The heat index has been consistently hitting 110-115 due to the humidity. Ambient temps are holding steady around 96-98 on a daily basis.

I have been driving the car off and on and with the AC cranking in stop and go traffic, the hottest I have seen my coolant temps is around 193-195. that was basicaly idling in traffic. As measured by my Dakota Digital Fan controller plumbed into the upper radiator hose and my Autometer cobalt electric gauge plumbed directly into the Very Nifty 1/8npt port directly on the radiator (My idea i might add http://forums.freshalloy.com/images/graemlins/smile.gif).

I am running all cooling plates including the ER plate over the top and the factory undertray on the bottom side. All my fender liners are in place as well so the air really has no place to go except through the radiator.

Nice Work by Kevin at C & R!

Sorry to bring back a thread thats been dead for a while, but I think this should be added to the "best of 240SX" forum. I was actually searching through there looking for this thread, I was suprised to see that it wasnt in there.

1) Using the search function on this website is an exact science. If you dont already know the name of the thread it can be difficult to find what you're looking for
2)Aside from that, the thread has some great info in it that could answer tons of questions for months to come.
3)You're not a moderator, therefore you cant decide whether or not this thread should be added to the best of forum...so, dont worry about it.

1. you dont need to know the exact name of the thread.
2.the thread does have good info. but if you look way into the thread it also has some info that isnt as helpful as some post that are still in the basic and adv sections.
3. i know im not a Mod nor do i expect that i would ever be one. Most mods also take into our considerations weather a topic be sent there anyways. I just said that there should be other threads that werent moved and should be so we all end up searching.

*also just realized my grammar was horrible in the post.

my badd for hi jacking the thread
