yes the Wrx is DRAG limited
which means you stock car will only able to push about 140-150 depending on wind factor and road conditions.
the stock out put of the car will not be able to outpower the air being pushed against the front of the car
little more HP will let you go little more faster thats about it
more HP = HIGHER SPEED for the 5sp (up till you hit the REV limiter)
well i wont even go close to that because I WANT TO STAY ALIVE AND OUT OF JAIL. =)
well eveyone be careful when you get up to though speeds
i dont want to here any one getting out of control and getting killed or killing anyone =(
