Question FC - oil cooler upgrade?

FC-turbo

Is there a kit available for upgraded oil coolers? Or has anyone built a kit that's been track tested?

No need, the OEM FC oil cooler is one of the best ones you can have

Many guys consider the FC cooler an upgrade...BMW and Volvos, I've heard.
Could repositioning or maybe ducting solve your problem and what drives you to ask anyway?

I'm running a big custom mounted setrab oil cooler with a fan on it and a improved racing thermostat and it works well.

You can also run two stock coolers in parallel :

But first make sure everything is ducted well. You still have the stock undertray right?

I run it liike this, 2 setrab 28row in parallel with ducting infront of them with big openings in the front bumper and venting it out thru louvres in the front fenders via the pictured air channel, the ductings are sealed both against the oil coolers and fenders/bumper. An-10lines with full flow fittings and no oil thermostat. Dual external hp1 sized oil filters and a oil distribution block with direct oil feed to the rotor bearings. 120psi oilpressure.

It will be track proven very soon but ill doubt it wont do its job :-)

The only real upgrade to an fc cooler is two fc coolers.

If you are ONLY considering the oilcooling alone you are right... But if you take aero, watercooling, intercooler, weight, airflow,a thermostat that can fail (like my did, and when i was gonna remove it it was so stuck that the threaded part in the oilcooler cracked) and the part where its actually a 30 year old item that probably got some wear and tear on it affecting its durability.

This is a great setup. I was hoping to do something similar but my intercooler piping is blocking a large portion of this space.

My issue is limited real estate with a fmic taking up much of the openings in the bumper. I am trying to find a solution that won't require spending on a v-mount setup.

I am probably the only person on this forum who would like his oil to get warmer.

That's a negative, unless you meant the cheaper way.

Im not knocking. I didnt really see his post. Nice set up. But yeah, im running a single FC oil cooler. Water is always 84-86 c. Oil is always a few degree cooler than that. Circuit racing cars around these parts usually weld two together to make one big one, which seems overkill to me. I think the secret to the efficiency on these coolers is the tubes have these "turbulator strips" inside them. There's some scientific principle I forget the name of where the turbulation increases heat conduction. They do tend to crack at the flanges from overtightening though, which is common on a 30yo item. New old stock are dynamite. Good second hand are worth finding.

I'm glad I have seen this thread. Was considering getting an aftermarket unit. Going to save money sticking with OEM.

Good choice on a street driven FC. In my experience, it takes FOREVER for the oil to get up to operating temp with the stock setup already.
