hahaha, well as long as its shiny
i had a r34 smic on my r33 for a short time running 12psi. on the dyno, the tuner wasnt happy. he said 'get rid of that piece of shite, and get a front mount' lol
basically it was limiting things.
anyway, a short time later i did. we made more power up top, and it was all nice and safe.
there was a small loss in throttle response. but the thing you'll notice the most is consistant performance.
with the smic, sometimes it would feel great, other days it felt average. and i did jump out of the car to check the heat of the smic after a good work out, and it was HOT.
the front mount doesnt get like that. its always cooler, especially on the exit side.
i cant comment on the stealth type fmic though. mine is the regular in one side, out the other.
