Under cap pressure, your coolant will boil at 264 Fahrenheit.
It would boil at 275 with a 70/30 mix.
As for the stock airbox, I gave proof that it was a restriction. Keeping the stock airbox lowers boost; if you get a cone filter, you get more boost. Boost increases as you decrease restrictions. Restrictions lower power to any engine. This is why you add an air filter, and free flowing exhaust; to remove engine restrictions. This is my proof, and If you had bothered to read my last post, you would have realised this.
You can continue to argue this point, but more and more it makes you look like you don't know what you are talking about.
If you DON'T think the stock air box is a restriction... tell me why race cars put the filter directly onto the turbo. Surely the filter gets heat soak, but they do so to eliminate the huge restriction of the the stock airbox, AFM, and s-tube.
Funny they don't keep the stock airbox, seeing as it doesn't limit airflow at all....
Don't need a dyno, airflow meter, or timeslip to realize that converting from a 4 square inch opening to a 120+ opening is the removal of a restriction. This is simplicity. Try and suck through a 1/16" straw, and then try to suck through 2" straw. Funny how the 2" straw is easier to suck through, and takes less power.... hmm.... but apparently, by your train of thought, the tinier straw should be easier....
Don't post **** if you don't know what you're talking about.

As for the airbox, I never said there was no restriction, I just said adding a cone in front of your afm or maf won't do jack. The afm is the biggest restriction. How much open area does it have there? Funny you mention that I have don't know what i am talking about. Actually, I have a Master's degree in aerodynamics. On the other hand, it is pretty obvious you have had no technical education whatsoever. But that's ok, cause engineers like me and all the automotive engineers who design intakes have been smoking crack all these years.

So what's your point on the coolant??? I just said the 50-50 mix gives adequate protection under typical coolant system pressure, which according to you is 264 deg.

Funny how you mention you're into aerodynamics, but can't tell me why boost is raised 2 psi with the addition of a cone filter if the stock air box isn't a big restriction? Hmm? Funny how you neglect and ignore this point.
You can tell us you know all about aerodynamics, but you know **** about RX-7 intakes, and its just been proven. Tell me, oh mighty RX-7 god, why every engine tuner I have talked to recommends ditching the crappy stock airbox as the first mod for RX-7's? Apparently this is unnecessary, and a waste of money right? Its fine if you don't believe me, but you can't argue with professionals.
I run a cone filter on my car, and my car makes more power than yours does, so maybe I know what I'm talking about.
Also, call me uneducated and stupid, but I am on full scholarship in engineering at UBC going into Eng phys, pulling a 96% average in my first year. Its obvious I know more about RX-7's and cars in general than you do, so careful who you call uneducated.
Don't believe me, I don't care. But maybe you should do a little actual research before you make statements like you have, and maybe consult with some professionals.

An afm is less restriction than the airbox??? Tell me, Mr. eng physicist, what is the inlet area on you afm? What is your stagnation pressure there? Ignorance may be corrected with the education you claim you are getting but not stupidity.

Oh yeah, one last thing before I stop posting on this thread..
I suggested using a k&n drop-in instead of cone. You keep harping on the increase in boost (may or may not be true, who knows?) versus the stock unit which I am sure included the paper filter. Did you compare it to a K&n drop-in? No!
Try and understand what someone has posted before you pounce on him.

Personally, I dropped the $162 for the K&N FIPK (part # 57-5005). It comes with the plate that bolts directly to the MAF sensor, all the mounting brackets, and has more surface area than a standard generic K&N cone. When coupled with a Mariah cold air box, it makes for agreat system.
Just my $.02

I have done testing. I am not saying the AFM isn'y a restriction, its just not as big of one as the stock air box.
Fact is: I have done testing. You haven't. Come back and argue when you have. We'll know if you did, b/c you'll report the same thing I am.
And Nigel, you are correct, a cold air box is better than just a cone filter, but with or without a cold air box, a cone filter folw better than even an empty stock air box.
Also, I'll appreciate you saving your insults of calling me stupid. You have now shown your maturity, as well as your ignorance for automotive knowledge.
