We all know cooling is an issue on our cars, especially if you have auto transmission since the lower portion of the radiator is used as trans cooler...

Just wondering if if anyone has used CSF radiator on our platform? The specs say it is an all aluminum core and end tank construction, much better than the plastic crap on the stock radiator.

FYI, they sell MT radiator as well! And the price is quite competitive comparing to the Mishimoto's radiator.

Anyway sent an email to the manufacturer for more information. These guys have been making performance radiators for quite a while, so it would be great there is finally something available for the e9x platform.

If their radiator does work on 6AT cars, I'd buy one in a heartbeat. Please keep us posted.

[moldysack]

I cosign on that, Id buy one in a heartbeat as well.

Sub'd

[whosdady]

I'm interested as well!

Ok, will update once they get back to me. If it looks all good, I will try to work out a group buy deal or something.

You won't see lower temps with the aftermarket radiators, just so you know.

As I predicted when mishimoto was designing theirs, the DME will just cycle the water pump less frequently because it is programmed to keep the water temp within a certain range.

If you guys want to run the coolant cooler, you really need to find the water pump logic and figure out how to adjust it.

You are right. JB4 allows you to toggle the water pump and fan to max. capacity, which works like a wonder for me on track. Honestly with JB4 and aux radiator and the mild summer temp here at midwest, I doubt I will need this upgrade.

But I haven't come across any way to modify the DME software for coolant management, so the guys running stock or on Cobb are out of luck on this. But a more efficient radiator can manage much higher thermal load before car's coolant hits limp mode temp. Given that stock BMW radiators are pretty prone to failure with the plastic end tanks, this could be a viable replacement for those who want a full alum. construction.

I agree that it should be a more reliable unit, and a step in the right direction. We just really need some software savvy people to find the tables in the DME, if there are any, to get the real solution rolling.

What about a low temp coolant thermostat like the one mishimoto sells ?

[sirdaft1]

I'd be onboard for this as well.

Just curious, has anyone with an AT bypassed the stock radiator and used a fender mounted trans cooler like the PPK setup?

A complete waste of money because the DME controls water temp not the thermostat…it will only take longer for the car to warm up, which some will argue has some benefits but also comes with drawbacks

not effective at all for reason stated above. best way to improve the coolant thermal management on our car is with higher capacity / faster running water pump, more aggressive pump operating logics, and more efficient radiator.

Ok well I hope someone can find that dme table

For what?

If you are at the track, just run max cool mode on the JB4.

If you have Cobb tune go eat a brick

[Julian2485]

I guess I'm eating a brick or 2 I have Cobb lol

or just run both, best of both worlds with no drawbacks other than being out $500

[Julian2485]

I ended up getting the low temp thermostat from mishimoto only to have you guys tell me it's a waste 😔

We used to carry the Performance Aluminum Radiator from Mishimoto.
we did not get any demand for it so we took it off our website.
Now that i see there is an interest i might add it back

How does this help the conversation... Mishimoto's radiator is really overpriced anyway; there is no reason a radiator should costs +$800 unless it has billet end tanks, lol. Plus they only made a MT specific radiator, which really isn't necessary at all... No wonder they never sold that many of them...

How is this an ad ?
We do not even carry the product anymore
i replied because the radiators were up on the website for a long time with no interest whatsoever and now suddenly everyone is sub and looking to buy one.
BTW your price is off, we did not have it anywhere near $800 ( but then again i cant go into details or it would be considered an ad).
Anyways it was a joke, we are not getting the product back on the website .
I know its still Monday and people are in a bad mood but seriously you need to relax and enjoy your day
