Dont bitch about reliability when the complete lack thereof is due to the choice of mods. Skimping on the details and trying to make more hp than your cooling system is capable of handling is a recipe for disaster, whether it has rotors or pistons.

Okay, but what other cooling solution is there? I am asking you for your answer.
It is my observation that even when all bases are covered, there's still a lot of heat generated because such a small motor is trying to output so much power in one ever-revolving system...
If radiator size, placement, coolant flushes, fan switch, ductwork, oil coolers, lines and caps are all taken care of, what more can you do? Drive at the track with the hood off? What more is there?

I THOUGHT THIS THREAD WAS ABOUT CRAZY ENGINES LIKE THE ROTOBLOCK THINGAMAJIGGER AND THE BEARE SIX-STROKE NOT YOU ******* LITTLE CUNTCASKET'S CEASELESS BICKERING ABOUT HOW LONG YOUR WANKEL WILL LAST

Simple answer. Those "bases" are not covered adequately. Just because its aftermarket and supposed to be better than stock, doesnt mean its the end-all. It just raises the limits somewhat higher than stock. And in this case, not enough higher than stock for many people. Theres likely not a bolt on solution that adequate cools a rotary capable of the power people are seeing with a big single. The nature of a rotary makes it waste a lot more heat through the cooling system than a piston engine, because of the long, wide, and thin combustion chamber. There is a high ratio of surface area to volume, much higher than anything with pistons.

LOL Is it me or have you not offered a solution yet? Still saying that replacing parts doesn't solve it, and that any ducting, refreshing/replacing, fans/vents combination won't save it either....so then what will?
Regardless, I think there's some that have found middle ground where perhaps a few laps of fun just need to be followed by a few calmer laps. Unfortunately, I am nowhere near the powerband or experience to be able to test such things...only in that in August I may be track'in my Stock-ish FD, but that won't account for much.

Im not looking to offer you a solution, merely to have you understand the nature of the problem that you bitch about so much. Its not a design flaw that makes FD's unreliable, its an owners flaw.

to offer a solution buy a oil temp gauge a water temp gauge and a ext temp gauge and study which one raises first. It is usually the oil. The stock 2nd gen cooler is good for about 250 hp driven hard after that my by and I go with bigger alomost twice the size oil coolers. A good ron davis radiator with electric fans tied in to a relay actaviated by the haltech becouse running the fan all the time ***** you. it only needs to run a certain temps below 35 mph.
When usng aftermarket parts you could use apc but stock is better. The best solution is to buy quality pars from reputable dealers and find someone that has a system that works and do that.
