We're throwing out a feeler for interest in our CSF manufactured direct fit, triple pass radiators. I've been running the CSF radiators in my GT3 on the track and see 15-20F lower temps.
The CSF cores use a B tube technology that increases the surface area over competitive all aluminum radiators and is slightly better than OEM (the OEM cores are very very good).
We are also adding attachments to the bottom of the radiator for the CSF E46 dual pass oil cooler, similar to what we use for our oil cooler kits, but should be much less expensive and far easier to attach!
We're targeting less than $500.00 for the radiator, we're releasing the design to production next week and I'll have the first article for fitment testing in a few months...
We'll have a special price on our electric fan kits as well and will run a special on the dual pass oil coolers that fit the bottom.
How would this radiator perform in the winter? I think it would adversely affect getting the engine to warm up to temp as quickly as the OE unit since this one is so efficient at cooling.
That's what the thermostat is for, it stops/slows flow to the radiator to keep the engine at operating temp. It's why the same car can drive through 110° and -30°. This radiator with it's better cooling qualities will just force the t-stat to close more often in cold weather.
I just need the new shroud. Preferably with cat flaps.
