It really depends what you call pointless....
On a NA, you don't have to worry so much about detonation (you know why). There are pros and cons, you and I went the turbo route (for different reasons); however knocking down the NA route, it is shameful IMHO!
You say pointless, I ask you what did you dyno? Did you ever hit the 200HP mark? Don't take this a attack, but more like "you didn't really get there" or "You didn't do things the proper way"
They did +220HP at the wheels on a street port 6 port engine, you and I know that a Ito's bridge will yeld higher numbers. Don't get me wrong, I know a T2 with the same amount of $$$ or a grand more will make WAY more power; but ever since I bought a miata, I have come to the conclusion that not everything is about HP

I havent gone the turbo route just yet, Im this damn close, so Im going to get some real numbers out of this engine. The only thing left for me is the intake manifold, which is in the process of being fabbed now. I want the numbers, just to finish off this learning experience. But regardless, in the quest for perfection, I have created a monster. I realized long ago that my creation would be a monster, but thought that it coule be domesticated. Sure, it could be tamed with enough work. But no matter what, you still have what accounts to a lion masquerading as a housecat. There is always that hard, sharp edge just below the velvety surface. That is not what I want in a car anymore.
And you brought out one more important point. Not everything is about power. This is where n/a's shine. The perfectly linear throttle response, and the huge usable powerband when done right. Not to mention the light weight, simplicity, etc. The list goes on and on. I am still a fan of n/a's, just decided I cant meed my current goals with one.
And if anyone is truly interested to see what a n/a can do, im helping a friend build a n/a motor for his miata. We're shooting for a peak power around 11K with enough civility to be a daily driver. And not to sound like Im contradicting myself here, but this project has the necessary funding and expertise to pull it off.
Hey J9, where did the thing about bridgeports not increasing torque come from? How about that IPRA bridge 13b I read about putting down 270 ft lbs at the flywheel at 3500 rpm? I do believe thats a little more torque than stock...

Im not knocking down n/a's. There are good reasons for building a n/a. A limited budget and power being on the top of the goal list are quite possibly the two worst reasons to build a n/a though. I guess it came across wrong, but I didnt mean to imply that n/a's were pointless. I meant trying to build one with those 2 specific caveats was.

the engine will need to be torn down about every 12-18months, because when you cut the water seal for the port the silicon doesnt last forever.
