TDR i/c allows way more air to the radiator
#42
frank - this ebay tubeNfin unit is practically a direct swap with the barNplate ebay cooler I now have (and fits w/o a/c mods).
If it were me building my setup from new, I'd go with the tubeNfin just in case- given the nature of cooling issues on a turbo Miata. Odds are, if it's reducing coolant temps tthen it's probably also improving the exhausting of hot air under the hood with greater flow through the radiator.
As it stands now, I can only create a rise in coolant temp when I come to stop after running hard (but the fan brings that down). But I'm sure that'd be different with a stock sized radiator.

I've got an older FM2 setup now but dang it must weigh 60 lbs and it has the all over the place piping. I do have a PWR rad and SPALs that came with the car and I installed, but the weight savings alone would be worth it for $140.
I always knew there was a reason the Suby STI came with a very light and smallish tube and fin and people seem to make great power with 'em tuned. Heat soak is only a problem at high boost, short bursts without speed limit cruisng to cool 'em back down.

They call it "Delta Fin"

There are now eBay/china copies of that design. At least they look like it on the outside. Wonder how it measures up compared to the tube/fin...

To bad the TDR IC cost like 8 times more then the average setup.

They call it delta fin in the auction, when I purchased it and saw the picture i didn't think anything else but tube&fin. I'll kinda be pissed if I get a true delta fin, because I want tube and fin.
