Maybe they're making progress. Or you got a good one. That's always been the real issue. It's pretty hit or miss on their quality.

When you were running the CSF radiator, were you running 50/50 antifreeze and water?

With the CSF I ran a 50/50 mix at first and I also ran a 70/30 mix with Recline Water wetter neither worked . I pretty ran simular temps to the OP of this thread witch is hot. One pull on the highway and your running real hot.

Those pics settle it for me.. Mishimoto is definitely the superior unit for performance applications.

The OP of this thread live in Texas look at the temperatures there hot over 200 degrees in 80-85 degree weather . I keep reading on this forum about CSF quality on this forum , and let me tell you my first hand experience. My CSF radiator bleeder screw crossed threaded just taking it out while trying to bleed the system of air , this also happened to a friend that has a similar set up to mine with a built motor his drain plus also crossed threaded . The CSF raditor was the only option for a while now there are better choices Mishimoto and GTM. The radiator is just to small its one row 30MM. It just won't cut it when it comes to pushing the car hard .

I ultimately believe that the GTM radiator would be the best for our cars its just very expensive.

I went with my $250 PWR radiator that required heavy modification of the support simply because the CSF was too expensive and too small for its price...

Didn't know the Mishimoto was so much larger or I might have just gone for that.

The GTM unit is marvelous, but it's really expensive...

Do you know what is the capacity differance in the radiators?

How big is the PWR radiator ?



I am not sure of the capacity difference but the Mishimoto is 40MM vs 30MM for the CSF ,and you can clearly see the size difference in the two.

Big. But like I said, took a lot of work to make it fit.

Do you still have AC in the car?

Im really shocked that Mishimoto made something better than CSF.

I went with CSF radiator because i was 90% sure that GTM fans will work with it (I wanted to go with GTM radiator but they didnt have it in stock at that time)

If radiator didnt cool the engine down then dont blame it on radiator, this car was not designed for boost so there is no air duct to engine as much as factory boosted car.

You cant really depend on radiator and throw it away if it didnt work out. you have to upgrade hood, bumper, hoses, fans, settings, etc.

I'm looking forward to your results and impressions of the CSF rad/GTM fan combo now that you've told us it fits. That may be my next purchase. If it works well in your climate, it'll be fine anywhere.

In my case the radiator just didn't have quick enough recovery in getting the temps back down so it was thrown away. Now upgrading the fans vent the hood will help, its still doesn't change the face that the CSF is to small. Once you start getting up there in higher boost levels it just cant keep up. Your combo of the CSF with the GTM fans should get better results than I had though. Once my bleeder screw crossed threaded I was done with it.

If anyone wants a used CSF radiator for cheap send me a pm.

I have the mishimoto radiator and it's awesome. Keeps the car cool in the hot n humid Miami. Yesterday had fun with an old school m5 and stayed cool after multiple high and long boost runs

Now this is from a SC standpoint which has a smaller intercooler.
Going from the OEM to CSF I saw a good drop in temp after pushing it and recovering, but the CSF is a bit small. It looks to be a solid upgrade for N/A track car, but throwing in boost and high rev driving I think it will fall short. Now new fans, hood, etc might bring it up against others but being smaller will keep it falling short.
