Their profession is making money. Rotaries just happen to be their area of business.

With a stock 146 HP when new that would put it a little past 20%

geez is it really THAT low? That's like in the miata range! I was hoping it would be around 125ish stock on a good engine.

...On the S4 Turbo (180 hp new) typically has rear wheel dyno runs of around 140-145 HP ....

:-( that's rather discouraging. As sonorous7 said that's like miata range!
If they lose 130 x .20 = 26hp (20%) I guess thats some consolation. But 110-115hp vs. 100-105hp...after considering the weight difference that sounds like a close race for our N/A friends....perhaps too close.

It would be awesome to have a 200 HP N/A... but what about fuel mods? Shouldn't you make fuel mods if you are going to make a few big intake/exhaust mods??

Actually you really just need a reasonable street port and custom intake manifolds (ie, dual throttles), and ported exhaust/headers wouldn't hurt.

And a standalone, obviously.
