Exactly. No arguement there. High HP Rotary due to FI=Short life.



High HP due to displacement=Awesome. Practical, obtainable, sensible? Not at all.

No. Short life = ignorant owners. Its universal. I know more people that have blown the engines in n/a hondas than in n/a RX7's.



What youre mising is the correlation between hp and heat. If youre doubling the hp of the car, you are doubling the amount of heat the engine will have remove to keep the engine at it ideal temperature. But just how many 450 rwhp FD's have the cooling capacity doubled? Fluidine radiator? Sure, its better than stock, but its far from doubling the amount of heat the cooling system can take out of the block.

what you are missing is my first fc a 90 s5 na died with 311,??? miles on it no piston motor can do that and even in no turbo conf it made 120hp out of a 1.3 lt so it made on avarage 90 hp per liter so a chevy 350 would have to make approx 535 hp to compare to size/power of a rotary. The last 500 +hp small block that I saw did not last antwhere near 300,000 miles it was lucky if it got a tenth of that.



my philospy could be flaued becouse drinmks are involved

How can you double it's capacity? You can do a V-mount with a big radiator, fans on high all of the time, proper ducting, coolant flushes, vented hood, and people will still report high/hot temperatures.



Also, as perfect as anyone sets up a high HP FD, problems still happen. Things fail all the time, but for a rotary, one spike or failure is one too much.



Man, this thread is making me look like a Rotary hater...:P

We've already discussed this. Your S5 NA lasted forever because it was NA, and as cool as 165hp is out of a 1.3litre motor, it's still only 165hp.

Like many others, you are completely overlooking the point that almost half of the rorary engine's cooling is through the oil.



Big oil coolers make a huge difference in cooling capacity.

I wouldn't count that out, that all of those speaking about said issues were only running one stock oil cooler...



But, like you, I have tried to be a skeptic with anyone posting problems, but I've talked to enough guys that knew what they were doing to make certain conclusions. And I believe, to the other extent, as you could agree: there's not much room for error.

I agree, there is very little room for error.

I hardly consider a v-mount a good solution. Laying the radiator down that much, especially with the air exiting below is far from ideal for airflow through the radiator.

But even still, you answered your own question. All that stuff you listed is STILL NOT ENOUGH cooling for the hp they are running.



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.
