i love how after i've supplied all the information anyone could want on how an aftermarket intake does not help AT ALL and possibly loses a couple ponies people still try to tell other people the first thing to do is intake and exhaust.
mazda is not honda guys, rx7's we're designed with a racing in mind. , the only mod that will help is going to a bigger AFM seeing as thats the smallest bottle neck on the stock intake system
any removal of the stock snorkle results in sever Heatsoak and the loss of power is extremely noticable

They seem to pretty much rely on the tailpipe sniffer and a good condition RX will have enough trouble passing with a functional airpump/cat, much less without.
Even if they did perform a visual test, I think a hi-flow cat would be OK.

Although I've seen mirrors on sticks (presumably to check under the car) at the EnviroTest stations, I've never actually seen anyone use them.

i have an intake Temp sensor installed after completely warming up it sits at about the same temperature as it is outside.
with a cone filter on once the car wars up intake air temps are about 127 F consistantly.
IMHO theres no need for 200+ hp in an FC...

Maybe he's talking about no need for a 200hp+ NA FC, in which case I'd tend to agree, on the road with that sort of power to the rear wheels would mean that you'd have to have a bunch of compromises that'd make it not a very streetable engine, in which case you'd be better off to have gone turbo.

ok, I am a physics major, and I can answer this. A flywheel stores mechanical energy like a battery stores electrical energy. Every time you rev your engine, you are spinning flywheel faster and storing more mechanical energy. The advantage is you can use that stored up energy to get the car moving in first gear. The disadvantage is that once you're moving, you can't stop "charging" the flywheel. Therefore its always siphoning off a little of the energy from your engine. While it doesn't increase the actual power produced by the burning of the fuel, it increases the power that reaches the wheels (where it really counts).
I can back this up with actual fomulae

not possible?
One thing I've learned is to never say never.
Claimed 300hp (assuming @ engine) on from vin 86 or 87 non turbo 13B..and it passes cali emissions...

edit....it is turbo, but still that is quite an accomplishment...being emissions legal

Are you talking about torque reaching the wheels or hp reaching the wheels? Neither HP or torque are static values, they change depending on the rpms and the gearing and heat and many other variables..not just the weight of the flywheel right? HP is a function of so many variables that I don't think you can just flat out say that the fly wheel has any more significance than if you changed your oil that day. Peak HP is something different. Again, I'm speculating so...who knows. just my 7 cents
The key thing here is that the flywheel doesn't have anything to do with the making of the power, what it does is parasitically absorb some power before it has a chance to reach the ground. A lower parasitic loss means more power to the ground.
